Is applying MMC in LASEK surgery safe enough?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hi doctor,

Is applying MMC in LASEK surgery safe enough? Concerning risk with corneal opacity from LASEK vs corneal 370 µm left after LASIK, which is greater?

Answered by Dr. Dadapeer. K

Hello,

Welcome to icliniq.com.

Applying MMC (Mitomycin-C) in LASEK is safer and in many studies, it has not caused any problems. So, you need not worry.

Coming to your second question, LASIK with 370 µm left, is very safe as we take the safety level as 250 µm. Hence I feel LASIK risk is lower.

For more information, consult an ophthalmologist online
