Vision correction and DNA testing

 

Avellino corneal dystrophy is a hereditary disorder in which the cornea gradually becomes cloudy, causing whitish opaque spots to form and leading to decreased vision. It is mainly caused by mutations in the TGFBI gene located on chromosome 5.

In people with a TGFBI gene mutation, an abnormally large amount of protein is produced in corneal wounds created during vision correction surgery. As these proteins continue to accumulate in the cornea, vision may progressively deteriorate, and in severe cases, it can eventually lead to blindness.

Therefore, it is essential to undergo Avellino corneal dystrophy screening before receiving vision correction surgery.

A DNA test can provide results within 60 minutes, allowing possible complications during vision correction procedures to be identified and prevented in advance based on the results.

Bright Eye Clinic Gangnam DNA Research Center

Bright Eye Clinic Gangnam operates an affiliated DNA Research Center for patients considering vision correction surgery. By taking genetic factors related to eye health into account, the clinic provides personalized treatment options. This allows patients to receive safer and more effective vision correction procedures while helping prevent potential side effects in advance.
