Changes in anterior chamber depth and intraocular pressure at day one after uneventful phacoemulsification surgery

Abstract

Objectives: This study aimed to determine the relationship of anterior chamber depth (ACD) change toward intraocular pressure (IOP) at day 1 after phacoemulsification surgery and intraocular lens implantation. Materials and Methods: This is an analytical cross-sectional study. Data were extracted from medical records of cataract patients above the age of 40 years who underwent phacoemulsification surgery at Christian University Hospital from September to November 2019. Each participant’s ACD (biometry) and IOP (non-contact tonometry) were determined before and on day 1 after phacoemulsification surgery. Comparison of ACD and IOP measurements was done using paired t-tests and the relationship was analysed with Pearson correlation testing. Results: Twenty-five eyes were included in this study. ACD pre-operative was 2.99 ± 0.599, and day 1 post-operative was 3.42 ± 0.349. ACD was significantly deepened on day 1 post-operative (P = 0.001). The mean pre- and 1-day post-operative IOP were 18.16 ± 3.460 and 17.32 ± 5.429, respectively (P = 0.412). No relationship was found between ACD and IOP pre-operative (P = 0.178). There was a statistically significant relationship between ACD and IOP day 1 post-operative (P = 0.002). Conclusion: ACD was significantly deepened 1 day post-operative, and there was a statistically significant relationship between ACD and IOP 1 day post uneventful phacoemulsification surgery.
