Purpose

To compare anterior chamber stability during cataract surgery and postoperative outcomes using Centurion with Active Sentry (AS) handpiece VS. Ozil handpiece in age-related cataract patients.

Setting

A prospective randomized controlled study.

Methods

Patients with age-related cataract aged 50-80 years who underwent surgery from November 2023 to April 2024 were randomly divided into two groups and underwent surgery with the AS handpiece or the Ozil handpiece, respectively, and were followed up for 1 month. The primary endpoint was intraoperative anterior chamber instability score. The secondary endpoints were central corneal thickness (CCT) and its change from preoperative values at 1 day after surgery, and the corneal endothelial cell density (ECD) and its change from preoperative values at 1 month after surgery.

Results

A total of 78 patients were included (39 in AS group / 39 in Ozil group). No statistical differences in baseline data and surgical parameters between the two groups. The intraoperative surge score was 1.05 ± 0.94 in AS group and 3.31 ± 1.59 in Ozil group  (P = 0.000). CCT at 1 day postop was 545.3 ± 33.0 μm in AS group and 543.0 ± 44.0 μm in Ozil group ( P = 0.792). CCT change at 1 day was 3.9 ± 28.4 μm in AS group and 9.5 ± 25.5 μm in Ozil group ( P = 0.361). ECD at 1 month postop was 2486.5 ± 313.3 in AS group and 2346.6 ± 376.7 in Ozil group (P = 0.079).  ECD change at 1 month was -141.8 ± 279.7 in AS group and -270.8 ± 332.0 in Ozil group (P = 0.067). No other statistical differences observed between the two groups.

Conclusions

Compared with the Ozil handpiece, the AS handpiece can significantly reduce intraoperative surge and improve the safety of cataract surgery.
