Abstract

Purpose: To analyze structure and recovery of corneal wound in different corneal incision size with or without stromal hydration in cataract surgery by using anterior segment optical coherence tomography.

Methods: Cataract surgeries were done by single surgeon. 2.2mm and 2.8mm cornea incision was made with diamond blade (ME-759®, Meyco, Swiss). Patients were divided into four groups according to incision size (2.2mm, 2.8mm), and with or without stromal hydration. Fifteen eyes were assigned to each group, and incision wounds were measured by using anterior segment optical coherence tomography (3D-OCT 2000, Topcon, Japan)at 2 hours, 1 day, 1 weak, 1 month, and 3months postoperatively. Corneal thickness, incision length, incision angle were measured and existence of epithelial, endothelial gaping, and descemet membrane detachment were inspected.

Results: Endothelial gape was greater in group with stromal hydration than in group without stromal hydration on operation day(p=0.023). Stromal hydration exerted greater influence on 2.2mm incision group than 2.8mm incision group. In stromal hydration group, corneal thickness has decreased more rapidly than in group without stromal hydration(P=0.018). No statistical significance was observed between two groups(2.2mm, 2.8mm) on operation day,regarding corneal thickness, endothelial gape, epithelial gape and descemet's membrane detachement.

Conclusions: Corneal wound by smaller incision may help maintaining structural stability, but could be more vulnerable to external stimulus such as stromal hydration.
