Cataract surgery

Cataract surgery involves replacing the clouded eye lens by an artificial one, thus restoring the former vision for 90% of all patients. Cataract is the most common eye disease for older people, the vision can deteriorate till such a point when it is fully lost. As time goes by, proteins of lens start to move or merge with each other, thus forming spots, which clouds the lens and prevents the light from penetrating to deeper layers of the eye. These spots are called cataract.

The only method to cure this disease and restore the eyesight is to surgically remove the clouded lens and replace it with an artificial one.

During cataract surgery, clouded eye lens is shattered and suctioned out through a small (2-2,5mm) incision. Through the same incision, new artificial lens is inserted into the cavity where the clouded lens was. This surgery is not painful and usually lasts about 20-30 minutes. It is performed under a local anaesthesia (the eye is numbed with eye drops or an injection is made into tissues, which surround the eye). The vision becomes better within the first few days and stabilizes within a few weeks after the surgery. The biggest change after this surgery is found in much stronger sharpness of eyesight and better colour vision.


  • vision gets worse gradually;
  • clouded eyesight;
  • yellowing of colours;
  • frequent changes in eyeglass;
  • sensitivity to bright light;
  • increasing difficulty with driving at night;
  • double vision in a single eye.

POSTOPERATIVE PERIOD: after a surgery, bandage is applied, in order to protect the eye.

Cataract surgery is outpatient, which means that stationary treatment is not required afterwards.
Patients are allowed to go home on the same day, after one to two hours since the end of surgery.

It is recommended to follow these several rules for the first two to four weeks after surgery:

  • avoid eye rubbing with hands;
  • do not lift any heavy objects;
  • avoid traumas, physical exercises, swimming;
  • do not work in a dusty environment;
  • avoid sudden temperature changes, wind;
  • protect eyes from direct sunlight, it is advisable to wear sunglasses;
