Costs and Healthcare Resource Utilization Associated with Posterior Capsule Opacification After Cataract Surgery with Five Different Intraocular Lenses: An Economic Analysis for Spain

PURPOSE: To estimate the economic impact of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser capsulotomy and its related complications for five different intraocular lenses (IOLs) from the payer and hospital perspectives in Spain. MATERIALS AND METHODS: The three-year incidence rates of Nd:YAG laser capsulotomy after cataract surgery with five different single-piece acrylic monofocal IOLs (AcrySof IOLs, AJL LLASY60, IOL Tech Stabibag, Medicontur Bi-flex, Zeiss Asphina) for 8293 patients were derived from odds ratios of multivariate analysis adjusted for age, gender, and diabetic retinopathy. A cost-consequence model for a hypothetical cohort of 2000 eyes was then developed to quantify the potential impact of Nd:YAG capsulotomy in terms of costs and time for each of the included IOLs, from the payer and hospital perspectives. RESULTS: The adjusted three-year Nd:YAG laser capsulotomy incidence was 5.0% (95% CI 3.9 to 6.1) for AcrySof and ranged from 26.0% to 44.0% for the other four IOLs. The average costs of Nd:YAG treatment and related complications were €261.90 for payers and €19.99 for hospitals. The average time needed for Nd:YAG treatment and related complications was 32.82 minutes. Model estimates based on 2000 hypothetical cataract surgeries showed that AcrySof IOLs could lead to cost savings between €110,259.90 and €205,591.50 for payers. For hospitals, time, and cost savings with AcrySof ranged from 230.29 hours and €8415.79 compared to Zeiss Asphina to 429.40 hours and €15,692.15 compared to AJL LLASY60 IOLs. CONCLUSION: Post cataract surgery, AcrySof IOLs were associated with a significantly lower incidence of Nd:YAG treatment and its subsequent complications compared to other IOLs. Our analysis shows that IOL choice is an important factor that can reduce the burden for patients, payers, and hospitals.
