Clinical Outcomes After Implantation of New Trifocal IOL
Purpose
To assess the effectiveness of a new trifocal intraocular lens(IOL).
Methods
In a retrospective study, 80 eyes in 42 patients with AT Lisa tri 839MP IOLs were included. Visual acuity, refraction, and complications were assessed over a 3-month follow up. Uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 63 cm, uncorrected near visual acuity (UNVA) at 40 cm were tested.
Results
The study included 80 eyes of 42 patients. The mean spherical equivalent changed from +0.51 diopters (D) ± 1.87 (SD) preoperatively to 0.16 ± 0.59 D at 3 months. The postoperative mean IOL power was +20.62±2.64 D. The mean corrected distance visual acuity was -0.03 ± 0.05 logMAR. Mean UDVA was 0.00 ± 0.08 logMAR. Mean UIVA was 0.180 ± 0.12 logMAR at 63cm, mean UNVA was 0.1 ± 0.08 logMAR at 40cm. At 3 months, 100% of the bilateral and 93% of the unilateral cases achieved a UNVA of 6/9 (0.18 logMAR) or better. No severe visual symptoms requiring an IOL exchange were reported.
Conclusion
The AT Lisa tri 839MP IOL provided good distance, intermediate and near visual outcomes with minimal adverse effects.
