Purpose: To compare the clinical outcomes obtained after implantation of 1 of 3 models of diffractive trifocal IOLs.
Setting: Hospital da Luz, Lisbon, Portugal.
Design: Prospective randomized comparative study.
Methods: Patients undergoing cataract surgery with bilateral implantation of 1 of 3 models of diffractive trifocal IOLs were enrolled. The IOL models implanted were the FineVision POD F, RayOne Trifocal, or the AcrySof IQ PanOptix IOL (30 eyes of 15 patients in each group). Visual acuity (VA), refraction, defocus curve, and contrast sensitivity outcomes were evaluated during a 3-month follow-up. Furthermore, the Quality of Vision questionnaire (QoV) was used to evaluate the frequency, severity, and discomfort of different visual symptoms.
Results: A total of 90 eyes of 45 patients were included. No statistically significant differences were found between groups in distance, intermediate, and near VA (P ≥ .112) and postoperative refraction (P ≥ .059). Postoperative binocular uncorrected intermediate VA of 0.10 logarithm of the minimum angle of resolution (logMAR) or better was found in 14 (93.33%) patients in the 3 groups. Postoperative binocular uncorrected near VA of 0.10 logMAR or better was found in 13 (86.67%), 14 (93.33%), and 13 (86.67%) patients in the POD F, RayOne, and PanOptix IOLs groups, respectively. No statistically significant differences were found between groups in scotopic contrast sensitivity with and without glare and in the QoV scores (P ≥ .057), except for the difference between the POD F and RayOne IOLs groups in depth perception severity, which was less in the RayOne IOL group (P = .019).
Conclusions: The 3 trifocal IOLs evaluated provided a complete visual restoration with good visual quality outcomes.
