Changes in Corneal Sensitivity after Cataract Surgery

Purpose: To evaluate the changes in corneal sensitivity following cataract surgery with a limbal incision. Methods: The sensitivity threshold was measured in 53 eyes following procedures using a superior limbal incision (42 eyes) or a temporal limbal incision (11 eyes). Results: The corneal sensitivity was significantly lower at the superior and temporal limbal incision sites after surgery than at the other sites (p<0.05). That sensitivity recovered 90% of its preoperative level 30 days post-operative. Conclusions: Corneal sensitivity decreased following cataract surgery using limbal incision. There were no significant differences in either the rate of decrease or recovery of corneal sensitivity according to the incision sites.
