Why it matters
Laser vision correction works by reshaping corneal tissue — so its thickness and regularity decide who is a safe candidate. A detailed corneal map is the heart of every serious assessment.

Thin or irregular corneas, and conditions such as keratoconus, generally exclude laser surgery. A refusal on corneal grounds protects your sight.
