Abstract
Cataract surgery had evolved into a refractive procedure aimed at improving patient satisfaction and postoperative visual quality. Advances in intraocular lens (IOL) design had expanded visual outcomes beyond distance vision to include intermediate and near vision, while also influencing visual disturbances and spectacle dependence. This study aimed to compare the impact of different IOL designs on postoperative visual quality and patient satisfaction following cataract surgery. This retrospective observational study included 120 patients who underwent uncomplicated cataract surgery with implantation of a single type of IOL. Patients were equally assigned to four groups: monofocal, enhanced monofocal, multifocal/trifocal, and extended depth-of-focus (EDOF) lenses. Postoperative outcomes included visual acuity, visual disturbances, patient satisfaction, and spectacle dependence. Statistical analysis involved descriptive statistics, chi-square tests, correlation analysis, and multivariate regression. Postoperative distance visual acuity was favorable across all IOL groups. Enhanced monofocal, multifocal/trifocal, and EDOF lenses demonstrated superior intermediate visual acuity compared with standard monofocal lenses, while multifocal/trifocal lenses achieved the best near visual acuity. Visual disturbances were more frequent in the multifocal/trifocal group, whereas monofocal and enhanced monofocal lenses showed fewer dysphotopsia symptoms. Patient satisfaction was high across all groups, with significantly higher spectacle independence observed in the multifocal/trifocal and EDOF groups. Intraocular lens type and spectacle independence were significant predictors of patient satisfaction. Overall, intraocular lens design played a key role in postoperative visual quality and functional outcomes, highlighting the importance of individualized IOL selection to optimize satisfaction after cataract surgery.
