My doctor told me I have Keratoconus and performed C3r on my eye. 1wk post-op, and my eyes are still very blurry.

Haziness/blurred vision after CXC surgery is common and part of the recovery process. If the haze persists there are treatment options your doctor can discuss with you.

Corneal haze (cloudness) after corneal cross linking is very common. In fact, haze is one sign that CXL has done something good to your cornea. In my experience all patients will have haze. The degree of it varies a lot, hence the degree of blurred vision varies as well. Excessive haze is not desirable and need treatemt which your doctor can recommend, hence importance to have the initial regular check up after CXL by your surgeon. Patients normally complain of blurred vision when CXL is performed on an eye with good vision / or the better seeing eye. I hope that answer your question
