Purpose: To investigate the change of ocular higher-order aberrations (HOA) after cataract surgery in the eyes of acute primary angle closure (PAC) attack with mid-dilated fixed pupil.
Methods: This study included eyes of patients with mid-fixed dilated pupil after acute primary angle closure attack. Also, uncomplicated cataract patients were enrolled as control. All the eyes had been underwent cataract surgery with phacoemulsification. Best-corrected visual acuity (BCVA, in logMAR) and HOA (i-Trace, Tracey technologies, Houston, TX) were evaluated preoperatively and postoperatively at 1 month. Paired t-test were used to compare preoperative and postoperative HOA values, and independent t-test for comparison of postoperative HOA in PAC and control groups.
Results: BCVA were significantly increased in PAC group (0.64 ± 0.51 vs. 0.43 ± 0.45, p=0.042, respectively), and in control group (0.51 ± 0.25 vs. 0.18 ± 0.15, p<0.001, respectively). Intraocular pressure were significantly decreased in both groups. In control group, coma-like, spherical-like, and high order total (HOT) aberrations were significantly changed (p=0.006, 0.008, 0.006, respectively) in internal optics aberrations. However, HOA values did not show significant changes in PAC group. HOT aberrations of entire eye after cataract surgery in PAC group were higher than those in control group (1.21 ± 1.13 vs. 0.41 ± 0.48, p=0.001).
Conclusions: This result suggests that HOAs change after cataract surgery were less profound in the eyes with mid-fixed dilated pupil after acute primary angle closure attack than uncomplicated cataract group.
