Visual Outcomes and Patient Satisfaction after Unilateral Implantation of a Diffractive Trifocal Intraocular Lens to Treat Cataract
To assess clinical outcomes and patient satisfaction after unilateral implantation of a diffractive trifocal intraocular lens (IOL) following phacoemulsification in unilateral cataract.Patients and
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).
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.
Unilateral implantation of trifocal intraocular lens can be considered as a safe and viable option in presbyopic patients with unilateral cataract. Keywords: Cataract; Surgery; Trifocal; Intraocular lens; Visual acuity.
