Visual Outcomes and Patient Satisfaction after Bilateral Implantation of an Enhanced Monofocal Intraocular Lens: A Single Blind Prospective Randomized Study

Purpose: To evaluate and compare the visual outcomes of an enhanced monofocal IOL with two different monofocal IOLs. Setting: Eye Clinic, Department of Medicine, Surgery and Health Sciences, University of Trieste, Trieste, Italy. Design: Prospective, single-centre, single-blind, randomized controlled clinical study. Methods: The study included patients undergoing phacoemulsification and IOL implantation. Patients were consecutively randomized by block randomization and assigned in a 1:1:1 allocation ratio to three study arms to bilaterally receive Tecnis® Eyhance (model ICB00) or Tecnis®1-piece (model ZCB00) or Alcon®1-piece (model Clareon, CNA0T0) respectively. Monocular and binocular (both corrected and uncorrected) visual acuities for far, intermediate and near were registered and compared among groups. To track changes in patient quality of life, the Catquest-9SF questionnaire was administered to each patient before and after cataract extraction. Results: A total of 90 patients (30 for each group) were enrolled. At 3 months follow-up, statistically significant differences for intermediate and near distance visual acuities were found between the three groups. Non-statistically significant differences were observed for distance visual acuities and the changes in Catquest-9SF scores. Conclusion: Tecnis® Eyhance ICB00 IOL provided better results in intermediate visual outcomes without negative effects on patients’ quality of life.
