AIM:To evaluate changes in corneal sensitivity of different positions following thin-flap laser in situ keratomileusis (LASIK).  METHODS:Corneal sensitivity was measured in 43 cases (84 eyes) before and 1 month, 3 months after correction of myopia by thin-flap LASIK. Sensitivity measurements were made with an esthesiometer at the central,temporal,inferior,nasal and superior points on the corneal flap.The data were statistically analysed. RESULTS:The corneal sensitivities after thin-flap LASIK were reduced during the first month after surgery at any points on the corneal flap. Corneal sensitivity was significantly decreased at the central point. The corneal sensitivities of all the positions except the central point were recovered to preoperative levels at postoperative 3 months.Compared with postoperative 1 month, the central corneal sensitivity significanthy recovered, which has statistical significance. However, compared with preoperation, it decreased, which also has statistical significance. CONCLUSION: The corneal sensitivity is significantly reduced following thin-flap LASIK during the first month, with a return to preoperative levels at postoperative 3 months. The recovery of central corneal sensitivity needs more time.
