Abstract

Précis: Monofocal, trifocal and trifocal toric intraocular lenses induce similar changes on overall retinal OCT measurements.
Purpose: To assess whether trifocal and trifocal toric intraocular lenses (IOL) affect the measurement of retinal parameters using spectral-domain optical coherence tomography (OCT).
Methods: This cross-over study included patients undergoing implantation of a trifocal IOL: AcrySof® IQ PanOptixTM, a trifocal toric IOL: AcrySof® IQ PanOptixTM Toric, and a monofocal IOL: AcrySof® IQ. The monofocal group was considered as the control group. The refractive target was emmetropia in all cases. Mean average macular thickness, macular volume and retinal fiber nerve layer (RFNL) thickness were measured with the Cirrus HD-OCT®. All measurements were performed before and three months after the surgery.
Results: The study analyzed 150 eyes of 150 patients (50 for each IOL group). Macular thickness and macular volume showed statistically significant differences before and after the surgery for the three groups (P<0.05 in all cases). RFNL thickness was found to be similar before and after the surgery in all groups (P>0.05 in all cases). Mean difference values (before and after the surgery) in the monocular, trifocal and trifocal toric group for macular thickness, macular volume and RFNL thickness were: 4.9±7.8, 7.9±10.0 and 7.7±13.7_µm, respectively; 0.1±0.2, 0.2±0.4 and 0.2±0.3_mm3, respectively; and 0.8±5.5, 1.3±6.0 and 0.8±6.7_µm, respectively. Mean differences were found to be similar for the three groups.
Conclusion: The trifocal and the trifocal toric IOLs under study did not induce an additional impact on spectral-domain OCT retinal measurements compared to monofocal IOLs.
