Postoperative Visual Performance With Two Models Of Trifocal Diffractive Intraocular Lenses

To evaluate and compare the clinical outcomes with two models of diffractive trifocal intraocular lens (IOL) during a 3-month follow-up.

 Veni-Vidi Eye Center, Istanbul, Turkey

Prospective comparative study including 40 eyes of 20 patients (46-78y) undergoing uneventful cataract surgery. Each patient was randomly assigned to one type of IOL, trifocal A-Clareon PanOptix, (20 eyes) or trifocal B-TECNIS Odyssey (20 eyes). Visual, refractive changes and a questionnaire about patients’ satisfaction and visual symptoms were evaluated in a 3-month follow-up. The binocular defocus curve was also measured at 3 months postoperatively.

No statistically significant differences between groups were found in postoperative uncorrected and corrected distance visual acuities (P=0.386). Postoperative 3 month uncorrected near (40 cm), intermediate (60 cm) and distant visual acuities were 0,12, 0,16, 0,03 logMAR in trifocal A and 0,09, 0,12, 0,05 in trifocal B groups respectively (p1=0.952 , p2=0.082, p3=0.406). Similar uncorrected near and intermediate and visual acuity were found during all follow-up in the trifocal group, which was consistent with differences among groups in binocular defocus curve. Spectacle independence was achieved in most of the patients in both groups. Very few patients had complaints of halo and glare in both groups.

Both of the trifocal diffractive IOLs are able to provide an effective visual restoration which is maintained during a 3-month follow-up.
