Abstract

Background: Sutureless clear corneal cataract incisions may be associated with an increased risk of endophthalmitis. Objective: To assess the degree of ocular surface fluid ingress into the anterior chamber of cadaveric human globes with clear corneal wounds. Methods: Self-sealing clear corneal incisions were created in 4 eyes, and intraocular pressure was controlled with an infusion cannula. To evaluate possible flow of surface fluid through the corneal wound, india ink was applied to the corneal surface while the intraocular pressure was varied, so as to simulate the intraocular pressure fluctuations secondary to blinking or eye squeezing. The optical density from aqueous samples of globes were measured both before and after india ink application using a spectrophotometer. Results: Aqueous aspirates from the 3 globes with sutureless clear corneal wounds revealed a significant increase in spectrophotometric readings (P
