is a complication after cataract extraction, characterized by secondary closure of the posterior capsulorhexis area by connective tissue. Clinically, the disease is manifested by a progressive decrease in visual acuity, deterioration of color perception, impaired dark adaptation, diplopia, and blurred vision. To confirm the diagnosis, visometry, eye biomicroscopy, ultrasound, and OPT are performed. Additionally, laboratory diagnostics are performed. To eliminate the clinical symptoms of secondary cataracts, an automated aspiration-irrigation system or a laser discision method is used.

General information

Diagnostics

Secondary cataract is a difficult pathology to diagnose, for the detection of which a complex of instrumental and laboratory research methods is used. An ophthalmological examination includes:

• Visometry. The technique allows you to determine the degree of decrease in visual acuity with and without correction.
• Biomicroscopy of the eye. The procedure is used to visualize clouding of the optical media, degenerative-dystrophic changes in the anterior part of the eyes.
• Ultrasound of the eye in A- and B-modes. The method makes it possible to evaluate the anatomical and physiological features of the structure of the organ of vision and the position of the IOL.
• Optical coherence tomography (OCT). The technique is used for additional study of the topography of the eyeball and intraorbital structures. The examination is indicated to identify pathological changes in the posterior chamber (dense connective tissue film and accumulation of Semmerring rings, Adamyuk-Elschnig cellular elements).

Instrumental diagnostics are informative only in cases of pronounced changes in the lens capsule. Laboratory methods are used in the early stages or to predict the risk of developing nosology. Additionally, for secondary cataracts the following is indicated:

• Measuring anti-inflammatory cytokine levels. The study is carried out using hybridization and immunofluorescence methods. The determination of an increased titer of cytokines in the blood serum correlates with the severity of inflammation at the postoperative stage.
• Study of antibody titer to the lens. An increase in antibody titer in the blood or tear fluid is associated with a high risk of secondary cataract formation.
• Cytological examination of film. Detection of Adamyuk-Elschnig cells and Semmerring rings is possible no earlier than 90 days after the initial surgical intervention, indicating a long course of the disease.

Treatment of secondary cataracts

Timely treatment measures make it possible to completely eliminate the clinical manifestations of the pathology and restore visual functions. Conservative therapy has not been developed. The following surgical treatment methods are used:

• Laser dissection of secondary cataracts. The laser capsulotomy technique involves making small perforations followed by complete removal of connective tissue growths. The surgical intervention is performed under regional anesthesia and does not limit the patient’s ability to work.
• Cataract removal using aspiration-irrigation system . The automated bimanual aspiration-irrigation technique makes it possible to remove the proliferating lens epithelium by forming two paracenteses in the cornea, introducing viscoelastic and mobilizing the IOL. Additionally, implantation of a capsular ring or capsulorhexis under an intraocular lens can be performed.

Prognosis and prevention

With timely diagnosis and treatment of secondary cataracts, the prognosis for life and ability to work is favorable. The lack of adequate therapy is the cause of frequent relapses; in the future, irreversible loss of visual functions is possible. Surgical prevention comes down to an individual approach to choosing the model, material and design of the edge of the intraocular lens, taking into account the anatomical and physiological features of the eye structure. Drug preventive measures require local and oral use of non-steroidal anti-inflammatory drugs and glucocorticosteroids in the pre- and postoperative period. Modern trends in the prevention of secondary cataracts involve the use of photodynamic therapy and monoclonal antibodies to lens epithelial cells.

Greetings, dear readers! You've probably heard that cataract surgery is not always successful. In some cases, secondary cataracts occur after lens replacement. It affects not the lens itself, but the capsule surrounding it, leading to its clouding and reduction.

In approximately 30% of cases, the first surgical intervention leads to recurrence of the disease. The only way to prevent relapse of the disease is to remove the clouded lens along with the capsule, but first things first.

Secondary cataract is the name given in ophthalmology to an eye disease in which the posterior lens capsule thickens and becomes cloudy.

It is noteworthy that this disease occurs not only in adults, but also in children, and in young patients this occurs much more often.

Let me remind you that during surgery to eliminate cataracts, the clouded lens is completely removed, but its posterior capsule remains in place.

Subsequently, a special intraocular lens is implanted into it, which is an artificial part that is an analogue of the natural lens.

After a certain time, the surface in which the posterior lens capsule is located undergoes some changes, leading to the proliferation of epithelial tissue.

It becomes cloudy, which often leads to another deterioration in vision due to a veil appearing before the eyes. As a result, the images perceived by the visual analyzer become unclear and blurry.

Due to the individual characteristics of the patient’s body, this moment cannot be predicted and prevented. This means that the appearance of secondary cataracts is not caused by a medical error, but by a number of other factors, which will be discussed further.

Reasons for the development of secondary cataracts

Despite the fact that medical science has quite well studied such pathology of the visual organs as cataracts, the root cause that leads to its re-development has not yet been established.

However, the following reasons can be identified why secondary cataracts develop:

1. Hereditary factor. If one of your close relatives has cataracts, the likelihood of its occurrence in children increases significantly.
2. Age characteristics. In most cases, this disease develops after 50 years.
3. Mechanical or chemical eye injuries.
4. Metabolic disease.
5. Lack of vitamins in the body.
6. Lack of eye protection during prolonged exposure to the sun.
7. Negative effects of UV rays on the organs of vision.
8. Abuse of alcohol and tobacco products.
9. Medical errors made during the first surgical intervention.

How to recognize secondary cataract?

When cataracts recur after replacing the natural “lens,” certain symptoms appear that cannot be ignored.

The development of this disease is indicated by the following signs:

• splitting of objects and images;
• the appearance of small dots before the eyes;
• the occurrence of difficulties in the reading process;
• predominance of yellow tint.

In the early stages of the development of the disease, patients usually do not notice a deterioration in visual functions, but over time, visual acuity gradually decreases, leading to loss of objective vision.

Features of the treatment of eye pathology

What to do if cataracts reoccur? Its treatment is carried out using 2 methods:

1. Laser dissection. It involves “burning” a hole in the lens capsule with a YAG laser to allow light to penetrate. This is necessary in order to restore visual functions. This method is the most modern, safe and painless.

The advantages of laser surgery to remove secondary cataracts are that complications almost never arise after it. In addition, it does not require additional examinations and strict limitation of physical activity during the rehabilitation period.

1. Mechanical capsulotomy. During the procedure, the cloudy film formed on the posterior capsule of the lens is removed. All manipulations are carried out using special tools.

Such surgical intervention is performed in cases of serious complications arising after repeated lens replacement, which threaten the patient with complete loss of vision.

The prices for the operation depend on the method of its implementation. For example, the cost of laser discision is 10,500 rubles per eye, and mechanical capsulotomy will cost patients 6,000-8,000 rubles.

Cataracts are an unpleasant disease, but nevertheless curable. Often, however, it is necessary to use surgical techniques to cope with it. But such intervention is not always successful and does not lead to a number of problems. And in certain situations, so-called secondary cataracts occur after lens replacement, which also requires treatment. How to proceed in this case?

What it is?

The usual so-called primary cataract develops due to clouding of the substance located in the lens. Treatment involves the intervention of surgeons - the natural lens will need to be replaced with a special lens. During the operation, one of the walls of the lens capsule is carefully excised, the affected lens is removed, and a new, artificial one is placed in its place. The first such operation was carried out in 1950 in Great Britain.

However, after surgery to rid the patient of this pathology, cataracts may appear again. But where does it come from if the lens has already been removed? The fact is that the lens capsule, which is quite soft and elastic, is not removed during surgery - a special intraocular lens is placed in it. And the walls of the remaining posterior capsule simply thicken and become overgrown with epithelium - in a healthy eye they are very thin, and thickened walls in an eye affected by cataracts and operated on lead to blurred vision. It’s just that light rays can no longer freely penetrate all the structures of the eye and reach the retina.

This is how a pathology called secondary cataract. The symptoms are very similar to the usual one, but in fact this is not a returning primary cataract, since the nature of the pathologies varies. The secondary type develops only after surgery to treat the primary.

On a note! Secondary cataracts usually occur in 30% of people who have had cataracts. Typically, the pathology develops within 6-18 months from the date of surgery.

Most often, secondary cataracts occur in people who suffered from the disease at a young age. In older patients, fibrosis of the lens capsule usually develops instead. Sometimes the incidence of the disease can be greatly influenced by the material and type of artificial lens implanted in the eye. For example, it appears more often from acrylic lenses than from silicone ones.

Table. Types of secondary cataracts.

Symptoms

There are not many symptoms of secondary cataracts, but it is thanks to their appearance (sometimes gradual) that it is possible to identify the developing disease in time. Signs include:

• deterioration in the quality of vision (gradual);
• blurred vision;
• change in color perception - all objects acquire yellowish tints;
• duality of the image, its distortion;
• increase in the level of photosensitivity;
• the appearance of black or white dots before the eyes;
• inability to correct vision with glasses;
• the appearance of glare in the eyes;
• the appearance of a cloudy focus on the pupil - a gray speck (in certain cases).

It is after the operation that it is impossible to say that a person may develop cataracts. And even improved vision does not guarantee the absence of its development. Therefore, it is very important, especially in the first year after surgery, to monitor your condition and, at the slightest sign of the development of secondary cataracts, go to the doctor.

Reasons for development

Secondary cataract is a fairly common complication. It can have several forms and each has its own reasons for its development.

Fibrosis of the posterior capsule is caused by the active development of epithelial cells, which is why the capsule becomes compacted. Visual acuity is significantly reduced. To call this pathology a pure secondary cataract would be somewhat incorrect.

May also develop pearly dystrophy, which is called secondary cataract. It occurs frequently, but its cause is the formation of defective lens fibers, which are called Adamyuk-Elschnig balls. Such fibers migrate over time into the central optical part and create cloudiness in the eye. Vision deteriorates due to the inability of light to pass through the lens capsule.

On a note! The development of secondary cataracts can be caused by diabetes mellitus, rheumatoid arthritis, etc. If performed incorrectly, it can also cause complications.

Risk factors that provoke the development of cataracts include:

• young age of the patient;
• eye injuries;
• inflammatory and non-inflammatory diseases of the organs of vision;
• metabolic problems;
• negative habits and unhealthy lifestyle;
• poisoning;
• heredity.

Treatment methods and diagnosis

If signs of cataract development appear, you should immediately visit an ophthalmologist. The doctor will conduct a diagnosis and determine whether the pathology is really developing or whether the deterioration in vision is caused by some other reasons.

Diagnostics includes:

• checking vision clarity;
• biomicroscopic eye examination using a special slit lamp. It will help determine the type of clouding of the capsule and will reveal the absence or presence of edema or any inflammation;
• measuring pressure inside the eye;
• fundus examination, which will reveal retinal detachment and a number of other problems;
• if macular edema is suspected, the doctor performs angiography or coherence tomography.

Treatment of secondary type cataracts can be done in two ways - laser and surgical. In the second case, the cloudy area is excised. The technique is applicable if secondary cataract has caused the development of a number of serious complications that threaten complete loss of vision. Previously, treatment was carried out only in this way, but over time it became possible to correct the pathology using laser technology.

Laser correction is a safe and simple method that does not threaten a person with the development of any complications and does not require a number of complex studies. The technique appeared and began to be used in 2004, it is called laser capsulotomy, is non-invasive and painless.

As a rule, a special laser is used to perform capsulotomy, powered by the so-called yttrium aluminum garnet with neodymium. Doctors call it a YAG laser (Latin abbreviation YAG). This laser is capable of destroying clouded tissue, anesthesia is performed by drip, and the procedure lasts no more than 10-15 minutes. Vision returns to normal immediately after treatment, the patient will be able to go home even while driving.

Contraindications

Fortunately, this operation has virtually no contraindications. However, it may be rescheduled due to a number of aspects:

• with corneal edema;
• due to cystoid edema of the macular area;
• for a number of pathologies of the retina or macula;
• for inflammatory diseases of the eyeball;
• due to a number of changes in the cornea, including its edema.

Prevention after surgery

The patient needs to monitor his health after routine cataract surgery on his own. Only if you follow all the recommendations of the ophthalmologist will you be able to protect yourself as much as possible from the development of complications. For example, for 4-6 weeks the patient must instill special eye drops that will protect them from the development of inflammatory processes. Lifting heavy objects, rubbing your eyes with your hands, or moving suddenly is also not a good idea. It is forbidden to go to the pool, bathhouse or sauna, play sports, or apply makeup.

Laser cataract correction can also be accompanied by complications if eye care rules are not followed. It is important to monitor eye pressure for 30-60 minutes immediately after surgery. If the pressure is normal, then the person simply goes home, where he independently carries out antibacterial and anti-inflammatory therapy for the time indicated by the doctor.

Attention! One of the most common complications after surgery is anterior uveitis. But it usually develops in the absence of proper care and non-compliance with doctor’s recommendations.

In the first weeks after surgery, “” may appear before your eyes, but you should not worry about this. They appear due to the fact that the remains of a destroyed lens capsule fall into a person’s field of vision. But if the spots do not disappear, then you need to visit a doctor. Decreased visual acuity should also cause concern.

How to prevent the development of cataracts

Sometimes preventing a disease is much easier than curing it. Let's look at how you can reduce the risk of developing cataracts in general.

Step 1. It is important to protect your eyes from the sun. Exposure to sunlight without eye protection for a long time is dangerous - it can cause the development of cataracts or even eye cancer. It is better to wear a Panama hat with a visor on your head, and sunglasses on your eyes. During the day, if possible, it is not recommended to be in the sun between 11 a.m. and 3 p.m.

Step 2. It is recommended to lead a healthy lifestyle, give up alcohol and cigarettes. Substances that the body receives due to bad habits can reduce the body’s regenerative processes and have a negative effect on the body as a whole.

Step 3. You need to eat right, include as many vegetables and greens in your menu as possible, as well as foods rich in vitamins E and C. The antioxidants contained in greens are good preventatives against cataracts.

Step 4. Doctors often associate cataracts with diabetes, which, in turn, is associated with obesity. Therefore, it is important to monitor your weight and exercise.

Step 5. Regular examinations by an ophthalmologist are required. In this case, the disease can be detected in the early stages and treatment will be easier.

Step 6. If you experience any symptoms of cataracts, it is important to see a doctor immediately.

Step 7 In your activities, it is important to use glasses and other means that help prevent cataracts and prevent its further development if it has already appeared.

Recurrent cataract (secondary) after lens replacement surgery

Surgical treatment of cataracts is considered a simple, quick and fairly safe procedure. It does not require preoperative preparation or hospital stay. It is performed on an outpatient basis, most often under local anesthesia. But despite its apparent simplicity, complications after this operation are not uncommon. One of the common complications is the development of recurrent cataracts after lens replacement.

Cloudiness of the lens of the right eye

Cataracts in general are clouding of the lens. This definition refers to primary cataract, the underlying disease of that name that requires surgery to replace the lens with an intraocular lens (IOL). After this operation, in 30-50% of cases, secondary cataracts may develop - also clouding, but of the posterior capsule of the lens. When replacing the lens for cataracts, this capsule is preserved and an intraocular lens is placed in it. But sometimes epithelial cells grow on this capsule, and as a result, clouding occurs.

What is the reason for this?

There is an opinion that repeated cataracts after lens replacement are the result of a medical error or a poorly performed operation. But that's not true. The exact causes of this complication are currently unknown. Perhaps, after removing the lens, particles of its cells remain on the capsule and proliferate, forming a film. Or perhaps it’s all about the reaction of the cells of the capsule itself to the artificial lens.

The following factors contribute to the development of secondary cataracts: risk factors:

How to recognize the development of pathology?

Secondary cataracts can occur at any time after surgery, even after many years. The disease develops gradually (although the rate of increase in symptoms varies from person to person).

This pathology is characterized by the following symptoms:

1. Gradual decrease in vision (its sharpness is lost, everything is seen as if in a fog);
2. The perception of colors and shades changes;
3. The image may appear double;
4. Possible photosensitivity;
5. Glare appears (when the capsule shrinks, this is a bad sign);
6. Sometimes you can see a cloudy focus on the pupil (a grayish spot on the black pupil).

The disease can affect one or both eyes.

If after lens replacement surgery your vision has improved, but after some time it begins to decrease again, you should definitely contact your doctor for examination and treatment.

What is needed to clarify the diagnosis?

Eye diagnostics by an ophthalmologist

Typically, the diagnosis of secondary cataracts does not cause problems. The main examination if it is suspected is a routine ophthalmological examination using a slit lamp. In this case, the doctor can clearly see the veil on the pupil, which allows you to immediately determine the degree of clouding. Visual acuity is also determined. These data are subsequently used to determine prognosis and treatment options.

What to do if you have secondary cataracts?

The first thing to do if there are signs of recurrent cataracts is to make an appointment with an ophthalmologist. After examination and examination, the doctor will decide on further treatment tactics.

If clouding of the posterior capsule of the lens has led to a significant deterioration in vision, a decrease in the quality of life, photophobia or, conversely, “night blindness” has appeared, surgical treatment is necessary. Doctors most often choose laser treatment for secondary cataracts, namely laser dissection. This is a fairly comfortable operation, since no incision is made into the eyeball, and local anesthesia is sufficient. However, to carry it out there is contraindications:

• bleeding disorders;
• metabolic diseases;
• autoimmune and chronic diseases in the acute stage;
• infections;
• oncological diseases;
• increased intracranial and/or intraocular pressure.

How is laser dissection performed?

Preoperative preparation of the patient

Before laser discision surgery for secondary cataracts, drops are applied to the cornea of ​​the eye to dilate the pupil. Then, a special apparatus produces several flashes of laser pulses that destroy the haze. This way the damaged capsule is cleaned. After the procedure, anti-inflammatory drops are instilled, which need to be used for several more days. A few hours after the operation, the patient can go home; hospitalization and observation in a hospital are not required for this intervention.

Possible complications after laser treatment of secondary cataracts

Despite the safety of this procedure, laser discision of a secondary cataract is an operation, which means that there may also be postoperative consequences after it. complications:

• mechanical damage to the intraocular lens;
• inflammation (uveitis, iridocyclitis);
• increased intraocular pressure;
• displacement of the artificial lens;
• swelling and/or retinal detachment;
• chronic endophthalmitis (inflammation of the internal structures of the eye).

Prevention of recurrent cataract development

After cataract lens replacement surgery, you must be examined by an ophthalmologist once a year. In the postoperative period, you must follow your doctor's instructions. Anti-catarrhal drops are often prescribed during this period. Under no circumstances should this recommendation be ignored. But you cannot use these drugs yourself if the doctor does not consider it necessary to prescribe them. On sunny days it is necessary to wear sunglasses with an ultraviolet filter, including in winter.

Despite the fact that secondary cataracts cause many fears and concerns among patients, the treatment of this disease is simple, and the prognosis for this disease is favorable. In most cases, vision can be restored completely and complications can be avoided. The most important thing is to see a doctor in time.

Secondary cataracts after lens replacement require treatment. Develops in every third person who has undergone lens replacement surgery. It occurs in all age groups, most often in people over 50–60 years of age.

– damage to the optical system of the eye when the lens becomes cloudy. In this case, the posterior capsule is usually preserved, which serves as a support for the new intraocular artificial lens. It is subject to repeated clouding, wrinkling due to thinning of the walls, and pathological proliferation of epithelial tissue.

Secondary cataracts are divided into 3 forms:

1. Fibrous cataract, when connective tissue elements grow.
2. Proliferative cataract, when specific cells are identified, indicating a long-term course of the process.
3. Thickening of the capsule, not accompanied by turbidity.

The first two forms of secondary cataract cause unpleasant symptoms.

Causes

The secondary form of the disease does not have a specific cause. There are predisposing factors:

• Leaving destroyed fragments due to the carelessness or inexperience of the surgeon.
• IOL materials. Acrylic lenses with a square edge are less likely than silicone lenses with a rounded edge to cause the development of secondary cataracts after surgery.
• Elderly age.
• Somatic diseases (autoimmune connective tissue diseases, arterial hypertension, thyroid dysfunction).
• Ophthalmological diseases (uveitis, high degree of myopia, glaucoma, retinal detachment, dystrophic changes in the organ of vision).
• Complications after.
• Hypovitaminosis, vitamin deficiency.
• Factors that irritate the visual organ: frequent exposure to bright sun, welding, caustic fumes, smoke.

The development of secondary cataracts after lens replacement has no clear causes. No specialist can guarantee that you will not experience repeated changes in the lens during the recovery period or after a few years. Eliminating predisposing factors will only reduce the risk of occurrence.

Symptoms

After eye surgery, a person may notice a progressive decrease in the quality of vision. This is how the first symptoms of secondary cataract begin after lens replacement. What other manifestations does the secondary form of the disease cause?

• Flashing flashes, sparks.
• , blurred vision.
• Double vision.
• Blurred vision.
• Impaired color perception.
• Fuzzy image, blurred contours.
• Focus problems.
• Decreased visual acuity. Spectacle correction is unsuccessful.

The clinical picture develops differently. For some, the secondary form appears sharply and suddenly, while for others it slowly progresses over years. Typically, the first symptoms appear no earlier than 3 months after phacoemulsification.

Diagnostics

Repeated cataracts are treated by an ophthalmologist. First, a series of examinations is prescribed. The doctor measures IOP. Uses Sivtsev-Golovin tables to assess visual acuity (visometry). Performs perimetry: determines the boundaries and areas of loss of visual fields.

Examination using a slit lamp (biomicroscopy) evaluates the structures of the eye, allows you to see the localization of the pathological focus, its size, and characteristics. If macular edema is suspected, fluorescein angiography and OCT (optical coherence tomography) are performed.

If a person has diseases of internal organs, he is referred for examination to doctors of the appropriate profile. Treatment of the underlying pathology and normalization of laboratory parameters are required. Otherwise, repeated cataracts will recur after treatment.

Treatment

Increasing visual impairment requires treatment of secondary cataracts. If left untreated, partial or complete blindness will develop over time. What removal methods are used to treat recurrent cataracts?

The best treatment for recurrent cataracts after lens replacement is laser dissection of the secondary cataract. Laser dissection is widely used and ophthalmic surgeons have extensive experience. Considered the gold standard of treatment, it is carried out quickly and does not require hospitalization.

Before the operation, mydriatics are instilled to dilate the pupil. A small hole is then created with a laser. Next, photodestruction of the altered tissue is carried out, i.e. dissection and destruction using a laser.

Treatment of secondary cataracts is a complex task. This is due to the frequent need for surgery and the impossibility of performing it due to concomitant diseases. In this case, conservative treatment methods help slow down the development of pathology and improve the quality of life. Patients are prescribed drops that have a positive effect on the condition of the lens, improve metabolic processes in it, and promote normal regeneration of damaged tissue. For example, a doctor may recommend Oftan Katahrom - Finnish eye drops with a proven clinical effect, which include the antioxidant cytochrome C, vitamin nicotinamide and the energy source adenosine.

Removal of secondary cataracts with a laser is low-traumatic; there is no need to insert surgical instruments into the eye cavity. 98% of people report significant improvement in vision. Contraindications to laser treatment of secondary cataracts: scars, opacities, swelling of the cornea, pathological changes in the fundus, inflammatory eye diseases.

The surgical method of removing secondary cataracts is outdated and rarely performed. It's called a capsulotomy. The essence of the method is to dissect the clouded lens capsule with surgical instruments. Surgical capsulotomy is dangerous due to the risk of traumatic damage to the structures of the visual organ. Has a long recovery period. Associated with an increased risk of infectious complications.

In the postoperative period, symptoms may be observed: redness of the eyes, swelling of the eyelids, lacrimation. This is the result of intervention on the visual organ. To improve a person’s condition, an ophthalmologist prescribes eye drops and ointments.

The goal is to prevent infectious complications, reduce inflammatory manifestations, and stabilize IOP. The course of local therapy is up to 1 week. During follow-up examinations after surgery, the doctor assesses the condition of the visual organ and decides whether to shorten or extend the course of therapy.

Prognosis and prevention

Laser dissection proceeds, as a rule, without complications. Secondary cataracts require re-intervention in only 2% of people. Most often, IOP increases within 3 hours after surgery. To reduce blood pressure drops are prescribed. A follow-up examination is required the next day.

Anterior uveitis is the second most common complication after surgery. To prevent it, antibacterial and anti-inflammatory local agents are prescribed. It is extremely rare for the macula or iris to swell, the retina to detach, the IOL to be damaged, or hemorrhage to occur. The reasons lie in defects in the operation.

Almost all people with the secondary form have a favorable prognosis. At the beginning of the recovery period, the quality of visual functions returns. In the first month, people complain of floating dots and the appearance of flashes before their eyes. The complaints will go away when the organ of vision is completely restored. In general, a person begins to see clearly within the first days after laser treatment.

• Wear sunglasses when going outside.
• Avoid eye makeup for 2-3 weeks.
• Instill the prescribed drops 3-4 times a day, duration is 1 week.
• Have a routine check-up the next day, a week and a month after surgery.
• At the first suspicious symptoms, immediately contact an ophthalmologist.

After the end of the recovery period, it is recommended to be observed by an ophthalmologist at least once a year. See your doctor even if you have no symptoms. Secondary cataracts can occur again. There is a risk, but it is minimal.
