Hi doctors.

I have an above average cornea thickness of about 580 microns in each eye. The degree in my left eye is about 850, astig 50 and right eye is 750, astig 125.

My doctor has recommended me to do corneal collagen cross linking in only my left eye, which left me quite confused as the degree difference between both my eyes isn’t a big difference. Also, I have an above average cornea thickness, so I’m not sure if going for CXL is worth it because of the steep price.

Can I get some advice on whether I should go ahead with CXL, and if it’s really necessary to prevent my degree from returning?
