Before undergoing vision correction surgery in South Korea, it’s advisable to undergo genetic testing to identify potential risks associated with corneal dystrophies. The Avellino Lab Universal Test is a widely recognized genetic screening that detects mutations in the TGFBI gene, responsible for various corneal dystrophies. This test is particularly crucial for patients considering procedures like LASIK, LASEK, or SMILE LASIK, as individuals with these mutations may experience rapid corneal opacity post-surgery, leading to vision loss. The test boasts 100% sensitivity and specificity, as demonstrated in large-scale clinical trials conducted in Korea . Notably, clinics such as B&VIIT Eye Center in Seoul have integrated this genetic screening into their preoperative assessments, offering a comprehensive 15-step examination process to ensure patient safety and optimal surgical outcomes .
Yes, I had vision correction surgery through Cloud Hospital at JRYN Eye Clinic and before the surgery, they did several important tests. These are not genetic tests, but they are very detailed eye checks to make sure your eyes are healthy and safe for the procedure.
The clinic checked things like cornea thickness, eye pressure, pupil size, and the shape of the cornea. These tests help the doctors—like Dr. Sang Youp Han, Dr. Heo Joong Gu or Dr. Lee Jae Jung—decide if LASIK or LASEK is right for you.
