Purpose: Academy IRIS® (Intelligent Research in Sight) Registry was used to determine the incidence of postoperative neodymium-doped yttrium aluminum garnet laser capsulotomy (Nd:YAG) and time to posterior capsular opacification (PCO) diagnosis based on intraocular lens (IOL) type and brand.
Methods: This retrospective analysis included eyes implanted with 1 of 2 IOL brands, with ≥ 365 days of follow-up available in the IRIS Registry, and ≥ 2 visits within 180 days of surgery. Analyses included Nd:YAG incidence due to PCO within 1 year after surgery by IOL type and brand, mean time to PCO diagnosis, and mean time to Nd:YAG.
Results: Of 89,947 eyes after cataract surgery, 24,834 (28%) had PCO diagnosis within 365 days, and 9262 (10%) underwent Nd:YAG; 4.1% of 57,523 eyes with monofocal and 21.2% of 32,424 eyes with diffractive multifocal (MF) or diffractive extended depth of focus (EDOF) IOLs had Nd:YAG. Nd:YAG was 3.2 times more likely in eyes with diffractive MF or diffractive EDOF IOLs versus monofocal. For monofocal IOLs, 3.2% of eyes with AcrySof® and 8.1% of eyes with Tecnis® had Nd:YAG (P< 0.0001). For diffractive MF or diffractive EDOF IOLs, 13.0% of eyes with AcrySof and 21.7% of eyes with Tecnis had Nd:YAG (P< 0.0001). Nd:YAG risk was 2.4 times higher in eyes with Tecnis versus AcrySof IOLs. Overall, mean time to PCO diagnosis and Nd:YAG was 150.7 and 180.7 days. Mean time to PCO for monofocal versus diffractive MF or diffractive EDOF IOLs was 165.3 versus 139.7 days (P< 0.0001). Mean time to Nd:YAG for monofocal versus diffractive MF or diffractive EDOF IOLs was 196.4 versus 175.3 days (P< 0.05).
Conclusion: Real-world data for AcrySof and Tecnis IOLs revealed lower Nd:YAG rates and longer time to PCO diagnosis and Nd:YAG after monofocal versus diffractive multifocal or diffractive EDOF implantation. Nd:YAG rates were significantly lower with AcrySof versus Tecnis IOLs.
