Visual efficacy after implantation of monofocal intraocular lens on one eye and higher-order aspheric IOL on the other eye

Abstract

Abstract Purpose: To compare clinical results after cataract surgery with Tecnis® Eyhance ICB00 and Tecnis® monofocal ZCB00 intraocular lenses in the same patient. Setting: Bucheon St. Mary’s Hospital, Catholic University of Korea. Design: Retrospective review. Method: 112 eyes of 56 patients underwent intraocular lens implantation using Eyhance ICB00 and monofocal ZCB00 in the same patient from April 2020 to February 2022. Pre-operative uncorrected visual acuity, post-operative far, intermediate, and near uncorrected visual acuity, and depth of focus were analyzed. Satisfaction and discomfort after cataract surgery were investigated by conducting a questionnaire survey. Results: There was no significant difference in the values between Eyhance ICB00 and monofocal ZCB00 groups before surgery. At two months postoperatively, the monofocal ZCB00 group had significantly higher distance visual acuity than the Eyhance ICB00 group. At one week, one month, and two months after surgery, the intermediate distance visual acuity was significantly higher in the Eyhance ICB00 group than in the monofocal ZCB00 group. There was no significant difference in near visual acuity between the two groups at one week or one month after surgery. In the survey conducted, most patients answered that their daily activities were not limited by their vision or glare. Conclusion: Inserting a high-aberration aspheric intraocular lens(IOL) at one eye rather than inserting a monofocal IOL in both eyes is better for improving distance and intermediate vision. In addition, there is no discomfort in daily life in patients with Eyhance ICB00 inserted into one eye and monofocal IOL into another eye.
