Comparison Of Clinical Outcomes Of Cataract Surgery Operating At Iop 30Mmhg Vs 60Mmhg In Cataract Patients With High Myopia

Patients with high myopic cataracts who planned to undergo cataract surgery were included and randomly divided into experimental (30mmHg) and control (60mmHg) groups in the study. The OCTA (VG S) was performed on both eyes to get central fovea thickness (CFT) and parafoveal vessel density, while axial lengths (AL), anterior chamber depth (ACD), Central corneal thickness (CCT) of both eyes were obtained by IOL Master700 before surgery and at 1day and 1 week after surgery. Cumulative dissipated energy (CDE), aspiration time, phaco time and estimated fluid usage (EFU) were obtained during surgery.

33 patients with high myopic cataract were enrolled. The aspiration time was longer in the experimental group than in the control group (73.6±17.46 vs 61.00±13.61, p=0.013). Percentage of CCT increase at 1d and 1w post-op of the experimental group was slightly lower than the control group (1d 2.08% vs 4.51%;1w 0.37% vs 0.76%). Two groups showed no statistically significant difference in the change of central fovea thickness and parafoveal vessel density from preoperative value at both 1w and 1d postoperatively.
