Abstract

Corneal epithelial mapping can help us identify early keratoconus while screening patients for corneal refractive surgery. Lasik, PRK (photorefractive keratectomy) & smile surgery included in our study and the corneal epithelial mean thickness was measured. In a cohort of 75 eyes, preoperative epithelial thickness was comparable in all 3 surgery groups as: (Mean epithelial thickness+/-SD) 54.26+/-4.13 in Lasik, 53.4+/-3.06 in PRK, 54.53+/-5.63 in smile with p value of 0.76. After 1 month of surgery, there was significant change in 3 surgery groups as: (Mean epithelial thickness+/-SD) 63.38+/-12.11in Lasik, 49.1+/-8.50 in PRK, 55.84+/-5.78 in smile with p value of 0.01. After 3 months of surgery, mean epithelial thickness+/-SD is 59.26+/-5.60 in Lasik, 54.3+/-4.32 in PRK, 56.07+/-4.99 in smile with p value of 0.01. It shows that significant epithelial remodeling occurs in initial 3 months after refractive surgery which is maximum in PRK and minimum in smile.
