Comparison of quality of life with two trifocal intraocular lenses under different lighting conditions

Abstract

Aims/Purpose: To evaluate the effect of two types of trifocal intraocular lenses on the visual quality of patients undergoing cataract surgery by assessing contrast sensitivity, halo perception and subjective visual satisfaction under photopic and mesopic lighting conditions.Methods: Observational, prospective, cross‐sectional study. The study was conducted at the Hospital Universitario Sanitas la Moraleja in Madrid. The study followed the principles of the Declaration of Helsinki. The sample included 16 cataract or lensectomy patients with bilateral implantation of one of the two intraocular lenses (IOL) under study: 20 eyes implanted with FineVision and 12 eyes implanted with PanOptix. After 30 days after surgery, contrast sensitivity was measured with the CSV‐1000 test (2.5 metres) for four spatial frequencies (3, 6, 12 and 18 c/g), halo perception was assessed with the Halo.V.1 software and finally quality of life was assessed with the VF‐14 questionnaire. A p‐value < 0.05 was considered a criterion for statistical significance.Results: Analysis of contrast sensitivity under photopic conditions showed significant differences greater for the FineVision lens of 0.15 log units at 3 c/g and 12 c/g frequencies between the two lenses under photopic illumination conditions (p‐value 0.034). However, there were no statistically significant differences in mesopic illumination conditions. Furthermore, there was no statistically significant difference when purchasing the perception of halos, with a p‐value (0.149). On the other hand, patients' subjective perception of quality of life scored worse in night vision (p‐value 0.023) and near vision (p‐value 0.046) when comparing the PanOptix lens and the FineVision.Conclusions: The FineVision IOL lens provides better contrast sensitivity in photopic illumination conditions than the PanOptix. However, in mesopic conditions, both IOL designs provide similar contrast sensitivity values for the far distance. On the other hand, although the lenses did not show statistically significant differences in halo perception, the FineVision shows better vision satisfaction results during night driving than the PanOptix.
