Sensitivity change in cornea and tear layer due to incision difference on cataract surgery with either manual small-incision cataract surgery or phacoemulsification.

Purpose: To describe corneal sensitivity changes caused by different incision methods-manual small-incision cataract surgery (manual SICS) and phacoemulsification-and their influence on tear film quantity and quality.

Methods: This was a prospective observational study conducted in 30 subjects undergoing manual SICS or phacoemulsification. Corneal sensitivity was assessed before and 1, 7, and 15 days after surgery by Cochet-Bonnet esthesiometer.
