Abstract

Purpose
To evaluate endothelial damage after cataract surgery in eyes affected by an angle-closure attack (ACA) and compare it to that in the unaffected fellow eyes (FEs) of patients with ACA and normal eyes (NEs).
Methods
The medical data of eyes affected by ACA, FEs (with no history of acute glaucoma attack), and NEs of patients who underwent cataract surgery with simultaneous intraocular lens implantation were retrospectively reviewed. Endothelial cell density (ECD) and central corneal thickness (CCT) measured before surgery and at 1 week, 1 month, and 3 months after surgery were analyzed, and the percentages of loss in ECD and increase in CCT of the three groups were compared.
Results
The study enrolled 140 eyes from 100 patients (50 eyes in the ACA group, 40 eyes in the FE group, and 50 eyes in the NE group). The mean ECD was significantly lower in the ACA group than in the other groups (p < 0.001). However, the percentage of ECD reduction was not significantly greater in the ACA group than in the other groups (p > 0.05). None of the eyes developed corneal edema at 3 months postoperatively. Moreover, the CCTs of the three groups were similar throughout the follow-up period (p > 0.05).
Conclusions
Phacoemulsification was not associated with greater endothelial cell loss in the ACA group than in the NE and FE groups. This finding shows that ACA history may not contribute to the exacerbation of corneal endothelial damage in cataract surgery.
