“Schools do routine vision checks, and I failed it in my right eye…[After undergoing iLink®™ FDA-approved cross-linking, my eye] went from basically blind to 20/20 with this [corrective] contact.”
– Louis Jahnigen, age 15
Fifteen-year-old Louis Jahnigen always thought he was just clumsy, until one day he failed a routine vision exam at school. At first, he simply thought he needed glasses to help improve the vision in his right eye. It wasn’t until an optometrist determined that he was living with progressive keratoconus that he realized he would need more than a pair of glasses.
After learning of his diagnosis, Louis was referred to Dr. Adam Kaufman of the Cincinnati Eye Institute to discuss available treatment options. It was during the appointment that Dr. Kaufman recommended he receive iLink® FDA-approved cross-linking to slow or halt the progression of his keratoconus. Not wanting his vision to continue to decline, Louis decided to have his right eye treated in September of 2021. Following the procedure, he was fitted with a corrective contact lens to improve his vision.
Now, Louis is once again able to spend time outdoors and participate in scouting events, all without worrying about his condition progressing. He’s also doing his part to raise awareness of the importance of regular school vision exams. Without the routine vision check at his school, he may not have known he was living with progressive keratoconus and he would not have been able to receive timely treatment to preserve his vision.
