Cataract surgery

Cataract is a clouding that develops in the eye’s internal lens. Eye lens is located in the anterior segment of an eye, called the iris (the colored part of an eye). The iris helps you to focus images thus providing a clear vision. Clouding of the lens leads to a visual deterioration.

Cataract symptoms are:

  • Painless loss of vision; 
  • The need for an eyeglass spectacle replacement; 
  • Night vision deterioration; 
  • The need for a bright light when reading a book.   

Cataract treatment 

In the initial stage of the cataract vision can be improved by simply replacing eyeglass spectacles but in time the vision will deteriorate due to a cataract progression. Cataract will never improve; it may only remain in the current stage or deteriorate slowly.

Cataract cannot be cured with medicine, drops or exercises. The only treatment with results is a removal of the natural lens and its replacement with an artificial lens. 

There are two main types of cataract surgery: 

  1. Phacoemulsification (Phaco) where an ultrasound is used;
  2. Conventional extracapsular cataract extraction (ECCE) with a manual expression.  

The advantages of Phacoemulsification:     

  • There is less stress on the inner endothelium of the cornea;
  • There is a less risk of postoperative complications. 

At the end of the surgery an artificial lens is inserted to rebuild the eye’s ability of focus, that is, to see clearly at different distances.

During the operation we use a microscope of a German company Zeiss and an ultrasound Phacoemulsification system of an USA manufacturer Alcon.
