Abstract

Purpose : Postoperative anterior chamber depth (ACD) is an important factor for predicting refractive outcome. There is controversy regarding the factors that affect postoperative ACD. This study aimed to determine the relationship between postoperative ACD and preoperative factors.

Methods : Seventy-three eyes undergoing cataract surgery were retrospectively evaluated. Axial length (AL), central corneal thickness (CCT), ACD, lens thickness (LT), white-to-white (WTW) distance, and mean keratometry readings (Km) were measured preoperatively and at least 2 months postoperatively by swept-source optical coherence tomography (Argos; Movu, Inc.). Anterior cortical (ACT), nuclear (NT), and posterior cortical (PCT) thicknesses were measured using the embedded software. Postoperative changes were evaluated for significance by a t-test. Simple and multiple regression analyses of postoperative ACD as a function of AL, CCT, ACD, LT, WTW, and Km were performed. We also evaluated the relationship of postoperative ACD with ACD + ACT, ACD + ACT + NT, and ACD + LT (corneal epithelium to anterior and posterior nuclear surfaces and posterior cortical surface, respectively).

Results : Pre and postoperative AL, ACD, LT, WTW, and Km differed significantly. Simple regression analysis revealed significant correlations between postoperative ACD and AL, preoperative ACD, LT, and WTW (β = 0.098, 0.613, 0.266, and 0.280, respectively; p < 0.001, all). Multiple regression analysis revealed significant correlations between postoperative ACD and preoperative ACD (β = 0.739; p < 0.001) and LT (β = 0.400; p = 0.003). Pearson’s correlation analysis revealed significant correlations between postoperative ACD and ACD + ACT, ACD + ACT + NT, and ACD + LT (R = 0.711, 0.641, and 0.618, respectively; p < 0.001).

Conclusions : Postoperative ACD is associated with preoperative ACD and LT. Evaluation of these two parameters will help predict postoperative ACD more accurately.
