Visual outcomes and safety after bilateral implantation of a trifocal presbyopia correcting intraocular lens in a Korean population: a prospective single-arm study

BackgroundTo investigate the 3-month postoperative performance and safety after implantation of a trifocal intraocular lens (IOL) in a Korean population.MethodsThis was a clinical, prospective, multicenter, single-arm study. Forty-four subjects (88 eyes) with bilateral cataract with expected postoperative corneal astigmatism of <1.00 diopter (D) and no ocular disease or eye condition underwent bilateral implantation of the AcrySof IQ<(R)> PanOptix IOL (TFNT00). Postoperative examination at 3months included binocular defocus curve; binocular best corrected distance visual acuity (BCDVA); monocular/binocular uncorrected VA (UCVA) at distance (4m), intermediate (60cm), and near (40cm); contrast sensitivity under photopic conditions with/without glare; and subjective outcomes, including satisfaction and spectacle independence.ResultsBinocular defocus curve at 3months after bilateral implantation showed VA of 0.1 logMAR or better from +0.5 D through -2.5 D. Binocular BCDVA meanSD at 4m was -0.050.07 logMAR. Binocular and monocular UCVA was 0.03 +/- 0.1 and 0.08 +/- 0.12 logMAR (4m), -0.00 +/- 0.11 and 0.05 +/- 0.13 logMAR (60cm), and 0.03 +/- 0.12 and 0.09 +/- 0.13 logMAR (40cm), respectively. Contrast sensitivity with glare was 1.67 +/- 0.13, 1.91 +/- 0.17, 1.54 +/- 0.21, and 1.14 +/- 0.20 log units at 3, 6, 12, and 18cycles/degree, respectively. At near and intermediate distances, 84 and 77% of subjects reported good/excellent satisfaction, and 84 and 91% of subjects reported spectacle independence, respectively.Conclusions p id=Par In a Korean population, visual performance of the trifocal TFNT00 IOL 3months postoperatively was <0.1 logMAR for binocular UCVA at all distances, with high subject satisfaction and spectacle independence.Trial registration p id="Par www.ClinicalTrials.gov (NCT03268746).
