Presbyopia Correction

What is Presbyopia?

Presbyopia is the condition where the crystalline lens of the human eye looses its flexibility. This normally occurs at the age of about 40 years.

What is the cause?

The lens in the human eye continues to grow and it produces more and more cells which will eventually result in the lens loosing its focusing ability. This was found to be the case by an American Ophthalmologist Dr R Schachar in 1994. The eye stops to grow in our teens but the lens continues to grow.

Presbyopia cannot be prevented. In farsighted people the loss of accommodation can occur at an even earlier age as these individuals have a greater need to accommodate. In myopic (shortsighted) people the eye can normally focus for near. When Presbyopia occurs they can normally read without spectacles depending on the degree of the myopia.

After Excimer Laser Vision correction or Phacic Lens Implantation patients would normally require spectacles to read. By a comprehensive examination by an Ophthalmologist we can determine the extent of the Presbyopia.

Correction of Presbyopia

This is mainly done by wearing close vision spectacles. However, Presbyopia can also be corrected by a surgical procedure developed by Dr Schacher whereby four tiny implants are inserted into the sclera (white) of the eye in small tunnels. The operation is done on the outside of the eye. This procedure allows the ciliary muscles to stretch and thus have an affect on the shape of the human lens. There is progressive improvement of the Presbyopia within three months. The ability to accommodate improves to that of a young adult.

 

 

The procedure is done under a local or general anesthetic in a sterile theatre environment.
