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

Abstract

To report visual and refractive outcomes after implantation of a trifocal intraocular lens (IOL) in highly myopic patients. Department of Ophthalmology, Goethe University, Frankfurt, Germany. Retrospective case series. 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 3months 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. 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). 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.
