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

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.
