YAG Capsulotomy Rates in Patients Following Cataract Surgery and Implantation of New Hydrophobic Preloaded Intraocular Lens in an Australian Cohort: 3-Year Results.
PURPOSE: To assess the risk of posterior capsular opacification (PCO) following implantation of the Clareon lens.
MATERIALS AND METHODS: Retrospective analysis was performed for 484 consecutive eyes that had undergone phacoemulsification and implantation of a monofocal lens (CNA0T) between April 2018 and February 2020. Eyes with other ocular pathology that may affect outcomes, previous refractive surgery or eyes corrected for a near target were excluded. Incidence of PCO and YAG capsulotomy was recorded and regression analysis was performed to determine risk factors associated with PCO formation.
RESULTS: Overall incidence of PCO following implantation of the CNA0T monofocal lens was 3.7% (18 eyes) at 1 year with 1.9% (9 eyes) undergoing YAG capsulotomy. At 3 years, 8.7% (42 eyes) had developed PCO and 4.1% (20 eyes) had undergone YAG capsulotomy cumulatively. Primary open angle glaucoma (POAG; OR = 6.53; 95% CI = 18.68, 2.28; P = 0.0005), age-related macular degeneration (AMD; OR = 2.35; 95% CI = 5.21, 1.06; P = 0.036), vitreomacular traction (VMT; OR = 7.32; 95% CI = 45.08, 1.19; P = 0.032), retinal vein occlusion (RVO; OR = 8.42; 95% CI = 38.99, 1.82; P = 0.006) and history of anti-VEGF therapy (OR = 3.22; 95% CI = 10.26, 1.01; P = 0.048) were positively associated with an increased risk of PCO.
CONCLUSIONS: Incidence of PCO requiring YAG capsulotomy was relatively low. However, certain co-morbidities were found to increase the risk of PCO development, most significantly POAG and RVO.
