Why are some people bad candidates for LASIK? Because they have a genetic condition called Granular corneal dystrophy (GCD), which causes the development of white or grayish granular deposits in the cornea.
Normally these spots develop slowly, over many years, causing a gradual clouding of vision. But LASIK surgery can worsen the density of the cloudiness to the point of severely diminished vision.
A new gene test offered by Avellino Laboratory USA may be crucial in identifying people who carry the GCD gene and therefore should not receive LASIK. According to a study that was published in Ophthalmic Epidemiology, one out of every 870 people is at risk of carrying the gene.
Often people with GCD do develop the small white spots in time to be disqualified by their LASIK surgeon. But for those who don’t yet have any spots in their cornea, the Avellino-GENE Detection System (AGDS) Test offers a safe way to discover if they carry the gene.
