Aim: To investigate the difference in postoperative Anterior Chamber Depth (ACD) following phacovitrectomy depending on the type of the vitreoretinal diseases, measured using optical biometry.

Methods: We investigated 14 eyes of 14 patients (11 males, 3 females; mean age 59.4 ± 8.4 years) with Rhegmatogenous Retinal Detachment (RRD) without macular involvement who underwent phacovitrectomy (RRD group), 14 eyes of 14 patients (10 males, 4 females; mean age 68.4 ± 4.7 years) with a macular hole (MH) who underwent phacovitrectomy (MH group), 24 eyes of 24 patients (14 males, 10 females; mean age 66.5 ± 7.6 years) with Epi Retinal Membrane (ERM) who underwent phacovitrectomy (ERM group), and 42 eyes of 29 patients (15 males, 14 females; mean age 71.4 ± 11.8 years) without macular disease who underwent cataract surgery (cataract group). ACD was measured prior to surgery and one month after surgery using optical biometry and was compared between groups. Results: The mean difference in ACD (postoperative ACD minus preoperative ACD) was 0.68 ± 0.38 mm in the RRD group, 1.12 ± 0.32 mm in the MH group, 1.04 ± 0.56 mm in the ERM group, and 1.00 ± 0.47 mm in the cataract group. Postoperative ACD in the RRD group was shallower compared to the other groups.

Conclusion: Postoperative ACD in patients with RRD is shallower compared to other groups, including patients with MH, making it one of the suspected causes of myopic shift in patients with RRD.
