PURPOSE: To compare the progression of posterior vitreous detachment (PVD) between eyes that underwent cataract surgery and eyes that did not undergo surgery in non-highly myopic patients.
METHODS: One-hundred twenty-five eyes of 125 patients scheduled for phacoemulsification and 125 eyes of 125 age-matched patients who did not undergo surgery were enrolled. PVD status was evaluated using swept-source optical coherence tomography at 2 days (baseline), and 1, 3, 6, and 12 months postoperatively, and classified into five stages: 0 (no), 1 (paramacular), 2 (perifoveal), 3 (peripapillary), and 4 (complete). The PVD stage and incidence of progression to complete PVD were compared between groups.
RESULTS: The mean PVD stage significantly progressed over the 12 months in the surgery group (P = 0.0004), but did not change significantly in the non-surgery group. The PVD stage did not differ significantly between groups at 2 days, or 1, 3, and 6 months postoperatively, but was significantly more progressed in the surgery group than in the non-surgery group at 12 months (P = 0.0390). After adjusting for age, sex, axial length, and baseline PVD stage, the relative risk for progression to complete PVD was 7.1-fold higher in the surgery group than in the non-surgery group (P < 0.0001, 95% confidence interval 2.9-17.3).
CONCLUSION: PVD progressed significantly faster in eyes after cataract surgery compared with eyes that did not undergo surgery, and the relative risk of progression to complete PVD was approximately seven-fold higher within 1 year, indicating that the risk for PVD-related diseases is high after cataract surgery.
