Abstract

Purpose: To investigate the clinical outcomes of new hydrophobic trifocal intraocular lens (IOL) with hydroxyethyl methacrylate (HEMA) in the Korean population.

Methods: This prospective, multicenter, and observational study evaluated the clinical outcomes of eighty eyes of 40 patients with age-related cataract underwent cataract surgery using CNWT (Clareon PanOptix). Assessment included monocular and binocular uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity (UIVA at 60cm), near visual acuity (UNVA at 40cm and 33cm), uncorrected defocus curves, questionnaires evaluating photic phenomena, spectacle independence and spectacle free satisfaction.

Results: At 3-month postoperatively, mean uncorrected binocular visual acuities were 0.04, 0.04, 0.03 logMAR at far, intermediate, and near distances respectively. All patients achieved uncorrected binocular VAs of 0.2 logMAR or better. Monocular and binocular defocus curve indicated a mean VA of 0.2 logMAR or better at the defocus range of +1.0 D to - 3.0D (100 cm to 33 cm) and +1.0 D to - 3.5 D (100 cm to 28 cm). High spectacle independence was observed at all distances, with 37.5% patients reporting photic phenomena.

Conclusions: The Clareon PanOptix IOL has shown positive clinical outcomes, providing a viable option for cataract surgery. These lenses effectively address patients' visual needs, especially in intermediate and near distance tasks, reducing dependence on glasses.
