My sister recently had corneal strengthening at SNU Eye Clinic with Dr. Won Yeo Kyoung, and I thought sharing her experience might help others considering it. She was advised to undergo the procedure because her cornea was slightly weakening, and her doctor wanted to prevent further progression.
During the consultation, they did several detailed eye tests and explained everything clearly—what the procedure does, how it helps stabilize the cornea, and what to expect afterward. That really reassured her.
The procedure itself was quite quick, and she said it was more uncomfortable than painful. Afterward, she had some light sensitivity and mild irritation for a couple of days, but it gradually improved. She followed the prescribed eye drops and avoided screen time as advised.
Now, a few weeks later, her eyes feel stable, and her follow-up showed good results. She’s relieved that it helps protect her vision long-term rather than just correcting it temporarily.
