Abstract
Abstract
Purpose: To assess clinical outcomes and patient satisfaction after unilateral implantation of a diffractive trifocal intraocular lens (IOL) following phacoemulsification in unilateral cataract.
Patients and Methods: This retrospective case series study included six males and five females. Patients underwent phacoemulsification and unilateral implantation of a trifocal IOL (AT LISA tri 839MP, Carl Zeiss Meditec, Jena, Germany). Visual acuity was evaluated at 1 month, 3 months, 1 year, and 2 years postoperatively. Monocular and binocular contrast sensitivity and patient satisfaction were evaluated at 2 years of follow-up using 25 item National Eye Institute visual functioning questionnaire (NEI VFQ-25).
Results: At 2 years, the mean uncorrected distance visual acuity was from 0.549 ± 0.32 to 0.021 ± 0.037 logMAR, uncorrected intermediate visual acuity was from 0.544 ± 0.31 to 0.018 ± 0.045 LogMAR, and uncorrected near visual acuity was from 0.52 ± 0.30 to 0.022 ± 0.045 LOGMAR showing a significant improvement in the operated eye. The VFQ-25 evaluation indicated that patients were satisfied with their outcomes. Also, Binocular contrast sensitivity measured by CSV1000 was similar to monocular contrast sensitivity.
Conclusion: Unilateral implantation of trifocal intraocular lens can be considered as a safe and viable option in presbyopic patients with unilateral cataract.
