ABSTRACT
Objective:To compare the changes in tear film stability and corneal sensitivity after laser-assisted subepithelial keratectomy (LASEK) and laser in situ keratomileusis (LASIK). Methods: Forty eyes of 20 patients underwent LASIK and 40 eyes of 20 patients underwent LASEK to correct mypia. The patients were observed for corneal sensitivity, tear break-up time (BUT) and Schirmer test under local anesthesia before and 1, 3 and 6 months after operation. The results were analyzed statistically. Results: The tear film stability and corneal sensitivity were decreased to some extent in both groups after operation. Compared with before operation, there were significant differences in corneal sensitivity 1, 3 and 6 months after operation and in BUT 1, 3 months after operation in LASIK group (P0.05). Conclusion: Both LASIK and LASEK influence the corneal sensitivity and tear film stability after operation; the influence diminishes with the recovery of the cornea. The influence in LASIK group is more serious and more persistent than that in LASEK group.
