Abstract

Purpose

To evaluate objective and subjective results after bilateral implantation of a diffractive trifocal intraocular lens (IOL) in a Mexican population.

Methods

Prospective, interventional case series involved 15 cataract surgery patients who underwent bilateral implantation of the trifocal Micro F lens FineVision IOL (PhysIOL, Liège, Belgium). Objective analysis involved assessment of monocular uncorrected distance (UDVA), near (UNVA) at 30 and 40 cm, and intermediate visual acuity (UIVA) at 50, 60, and 70 cm, preoperatively, and at postoperative months 1, 3, and 6. Higher-order aberrations were assessed via aberrometry. Contrast sensitivity was determined via modulation transfer function. Subjective outcomes were assessed using the National Eye Institute Visual Functioning Questionnaire-25 (VFQ-25).

Results

At postoperative month 6, mean monocular UDVA was 0.06 ± 0.11 logMAR, and UNVA was 0.03 ± 0.04 logMAR at 30 cm and 0.05 ± 0.08 logMAR at 40 cm. Mean UIVA at 50, 60, and 70 cm was 0.12 ± 0.06, 0.13 ± 0.08, and 0.04 ± 0.08 logMAR, respectively. Spherical equivalent at postoperative month 3 was 0.23 ± 0.4 diopters (D). Aberrometry revealed a mean RMS of 0.18 microm and PSF of 0.19 (Strehl ratio). VFQ-25 questionnaire results showed a mean score of 93.64 ± 4.19 points (maximum 100 points). Vision during distance and near activities was reported as “excellent.” Adverse events were reported as occurring “never to occasionally.”

Conclusion

Implantation of a diffractive trifocal IOL in a Mexican population appears safe and effective, both objectively and subjectively. Good uncorrected visual acuity outcomes were achieved at far, near, and intermediate distances. Overall patient satisfaction was excellent.
