Abstract

Objective: This study was conducted to evaluate corneal endothelial cell changes after Phaco surgery with or without Goniosynechialyis on patients with primary angle-closure glaucoma using cohesive viscoelastic with dispersive viscoelastic at the Glaucoma Department - Viet Nam National Eye Hospital. Patients and Methods: Primary angle- closure glaucoma patients with cataract who has operated phacoemulsification with or without goniosysechialysis. Clinical interventional study was conducted at Glaucoma Department,  Viet Nam National Eye Hospital from August 2024 to December 2024. Results: The average age of the study group: 70% of patients were over 65 years old, 26,7% were 50-65 and 3,3% were under 50 years old. Before surgery: Mean preoperative intraocular pressure was 23,67±8,52 mmHg. Average visual acuity before surgery was 1,48±0,46 logMAR. 2 months post - surgery: 100% patients had controlled intraocular pressure without medications with average intraocular pressure of 15,1±4,85 mmHg. Average visual acuity: 0,76±0,53 logMAR. The average endothelial cell density decreased from 2838±407,87 cell/mm² pre-surery to 2615,97± 361,52 cell/mm^2. post - surgery with endothelial cell loss of 8,63±5,04%. Conclusion: Using both cohesive viscoelastic and dispersive viscoelastic help to protect effectively corneal endothelial cells during phacoemulsification sugery with or without goniosysnechialysis on primary angle closure patients.
