Cataract FAQ

The consequences of ignoring the disease can be sad. Fear and little knowledge about the disease raises many questions that we will try to answer on this page.

What is a cataract?

A cataract is a condition where the lens, which is inside the eye behind the pupil, loses its transparency. This results in a barrier to light beams that would freely penetrate into the eye with normal vision. Therefore, the main symptom of cataracts is a significant deterioration in vision. In addition, the person suffering from this disorder has the sensation of flickering in form of stripes, strokes, and spots, a blinding glare around objects in bright light. There is also difficulty in reading, writing, and working with small details.


What is the cause of cataracts?

One of the causes of cataracts lies in changes in the biochemical composition of the crystalline lens, most often associated with age-related alterations in the body, a disruption of its blood supply, and nutrition. Therefore, unfortunately, no one is safe from this eye condition. One could say that if all people lived to 120-150 years old, everyone would have cataracts.


What is phacoemulsification surgery?

Unlike the classic (old) technique, there are no sutures after this surgery because the corneal micro-access is so small (up to 1.8 mm) that it seals on its own afterward.

The surgery is performed within 10 to 15 minutes, in one-day mode. Local droplet anesthesia used during phacoemulsification completely excludes painful sensations and complications from the cardiovascular system. During treatment, the turbid crystalline lens is emulsified with ultrasound and then removed from the eye. A folding intraocular lens is implanted in its place, which unfolds automatically and fixes securely inside the eye.


What will my vision be like after cataract surgery?

The feelings of someone who has undergone cataract surgery can be described as follows. Just imagine that in your youth you looked at the world through a transparent glass, and over time, layers of dust settled on it. Colors became less bright and juicy, and objects lost their sharp outlines. After the surgery, you will get the impression of turning back the clock and seeing again as well as you once did.

The intraocular lens characteristics are calculated based on the parameters of a particular eye, so after the surgery, a person can simultaneously get rid of cataracts, as well as myopia, hyperopia, astigmatism, if he/she suffered before. The result will be better vision than before the cataract. In the majority of cases, modern methods allow considering the patient’s wishes regarding the future vision. Today, such intraocular lenses are used that possess practically all the properties of the natural crystalline lens, making it possible to see well both close and distant objects and to limit considerably the use of glasses or even to get rid of them.

Of course, the result largely depends on whether the patient has concomitant diseases, such as glaucoma or macular dystrophy. These conditions can also have a significant impact on eye functions and prevent full recovery of vision.


Do I have to undergo vision diagnostics and general examinations before surgery?

A complete diagnostic examination of the visual system is the key to successful treatment. Vision diagnostics at Eximer Ophthalmology Clinic is conducted with modern computerized equipment, which provides an objective and complete picture of the cornea, lens, retina, i.e., the entire visual system, as well as estimates regarding the artificial lens.


Do I need glasses after cataract surgery?

After cataract surgery, the patient usually needs glasses when reading, writing, and working with small details. After all, the surgery removes the affected cataract lens but does not restore the accommodation, that is, the ability to see well at close and far distances at the same time.

However, thanks to recent developments in intraocular lenses, it is now possible to significantly reduce a patient’s dependence on glasses or to get rid of them at all. For this purpose, Eximer Ophthalmology Clinic implants high-tech multifocal, toric lenses.


Are there any restrictions after surgery?

There are very few restrictions after modern phacoemulsification surgery. Doctors warn patients that in the first month after surgery they must guard their eyes against excessive strain, avoid sharp inclinations, prevent sudden temperature changes, avoid rubbing the operated eyes, and avoid alcohol abuse. However, as before, you may watch TV, read, write, bathe, and eat anything. If bright light causes discomfort, you can wear sunglasses.


What is the maximum possible age for cataract surgery?

The high reliability and predictability of phacoemulsification technology along with attenuated local anesthesia allow this method to be used for treating patients of different ages. Thus, the oldest Eximer`s patient who had a cataract extracted was 98 years old and the youngest patient was only 5 months old.


How long does it take for my eyesight to restore after the surgery?

After phacoemulsification, the patient sees quite well in just several hours, and full visual stabilization occurs within a week.


Do I need hospitalization for cataract extraction?

There is no need to go to the hospital. Eximer Ophthalmology Clinic performs the surgery on the same day, within 10 to 15 minutes. The patient may go home the same day after being examined by the doctor.


How often will I need to see a doctor after surgery?

After surgery, the attending physician will determine a schedule for preventive check-ups. Usually, patients are examined the day after surgery, and then in one week, one month, three months, and more often if necessary. It all depends on the individual peculiarities of the visual system.
