Visual Performance and Optical Quality after Implantation of a New Generation Monofocal Intraocular Lens
Purpose: To evaluate the performance of two intraocular lenses (IOLs). The new monofocal IOL using a higher-order asphericoptic (Tecnis Eyhance ICB00) was compared to a standard monofocal IOL (Tecnis monofocal ZCB00) of the identical platformand material. Methods: The medical records of the patients who had undergone cataract surgery with implantation of either the ZCB00or the ICB00 in the dominant eye from March 2020 to August 2020 and with available data from the 3-month visit were reviewed. Subjects with ocular comorbidities or corneal astigmatism greater than 1.00 diopters were excluded. The uncorrectednear, intermediate, distance visual acuity and corrected distance visual acuity were the main outcome measures. Opticalquality parameters measured using an optical quality analysis system, clinical records including age, sex, laterality, oculardominance, and information related to refractory errors was also collected. Parameters related to the refractory errors wereall uniformly based on the Barrett Universal II formula. Results: Of the 197 recruited patients, 111 and 86 were implanted with the ICB00 and ZCB00, respectively. No statisticallysignificant differences in baseline parameters were observed between the two groups. While no statistically significant differencesin distance visual acuity or optical quality were found between the two groups, compared to the ZCB00 group, theICB00 group showed significantly higher intermediate visual acuity (p < 0.001) and near visual acuity (p < 0.05) 3 months postoperatively. Conclusions: ICB00 provided superior intermediate vision and comparable distance performance and photic phenomenacompared to a standard monofocal IOL.
