Visual results after implantation of a trifocal intraocular lens in high myopes

Abstract

PURPOSE: To report visual and refractive outcomes after implantation of a trifocal intraocular lens (IOL) in highly myopic patients. SETTING: Department of Ophthalmology, Goethe University, Frankfurt, Germany. DESIGN: Retrospective case series. METHODS: This study included eyes with previous phacoemulsification and implantation of a trifocal IOL (AT LISA tri 839MP or 939MP) with an IOL power between 0.0 diopter (D) and 10.0 D. Postoperative outcomes at 3 months including uncorrected distance (UDVA), intermediate (UIVA), and near visual acuity (UNVA), corrected distance visual acuity, spherical equivalent, and refractive astigmatism were analyzed. Age-matched eyes after implantation of the same trifocal IOL with higher dioptric power (>10.0 D) served as controls. RESULTS: Thirty-six eyes of 19 patients were included: 18 eyes (10 patients) in the highly myopic group (IOL power 0.0 to 10.0 D) and 18 eyes (9 patients) in the age-matched control group (IOL power >10.0 D). Three months postoperatively, the mean UDVA, UIVA, and UNVA in the highly myopic group were 0.06 logarithm of the minimum angle of resolution (logMAR) ± 0.08 (SD), 0.13 ± 0.09 logMAR, and 0.12 ± 0.07 logMAR, and -0.01 ± 0.10 logMAR, 0.04 ± 0.10 logMAR, and 0.04 ± 0.11 logMAR in the control group, respectively (P = .022, P = .033, P = .053, respectively). CONCLUSION: Implantation of a trifocal IOL in highly myopic eyes with low IOL power (0.0 to 10.0 D) provided satisfactory short-term visual and refractive outcomes; however, results were not as good as those obtained in eyes with higher dioptric IOL power.
