Abstract :
Background: Cataract surgery results in diminished corneal sensitivity, as the procedure involves damage to the normal organization of corneal innervations. The objective of this study is to measure the corneal sensitivity after different types of cataract surgeries.
Methods: A hospital based cross-sectional study was done in patients who were phakic in one eye and pseudophakic in the other, above the age of 45 years. Only patients in whom a minimum of 3 months passed after surgery were taken. Corneal sensitivity was assessed by a Cochet- Bonnet esthesiometer.
Results: The corneal sensitivity following cataract surgery was decreased 9(50%) in SICS superior incision, 12(57.1%) in SICS temporal and 18(85.7%) in corneal incision phacoemulsification by comparing it to the phakic eye of the same group, which has normal corneal sensitivity.
Conclusion: This study suggests that a thorough ocular evaluation of all pre and post-operative patients of cataract surgery should include evaluation for corneal sensitivity.
