Abstract

Objective: To assess the outcome of phacoemulsification in shallow anterior chamber eyes according to different nuclear density. Methods: This was a prospective case-control study. Seventy-one eyes of 62 patients including 39 eyes in the shallow anterior chamber group and 32 eyes in the control group underwent phacoemulsification surgery with intracapsular intraocular lens implantation. The study was conducted at HCMC Eye Hospital, from February 2024 to September 2024. All eyes were divided into 3 subgroups according to three nuclear opalescence (NO): NO2, NO3, NO4. Corrected distance visual acuity (CDVA) was measured prior surgery and re-examined at 1 week, 1 month postoperatively. Surgical parameters including UST, CDE, PHACO power, the volume of BSS used were obtained. Results: In our study, the mean age in the shallow anterior chamber group was 67.08 ± 9.57 years, and mean anterior chamber depth (ACD) was 2.34 ± 0.23 mm. There was a postoperative improvement in logMAR CDVA among the shallow anterior chamber group and the control group, the difference was not statistically significant. The shallow anterior chamber group used a longer UST than the control group in the NO3 subgroup (P<0,01). Eyes with mean ACD 2.28 ± 0.31 mm required prolonged UST (>60s). BSS use showed higher in the shallow anterior chamber group than the control group, in the NO2 (P<0,05) and NO3 (P<0,01). There was a statistically significant inverse correlation between ACD and UST, BSS use in the NO3. Conclusion: Measuring ACD prior surgery would help the surgeons to assess the difficulty and intraoperative risks
