Comparison of visual effects and optical quality between LS-313 MF15 with regional multifocal and Rayner 920H intraocular lens after implantation surgery

The aim was to investigate the visual effects and optical quality differences between artificial lens LS-313 MF15 with regional multifocal characteristics and artificial lens Rayner 920H after implantation. This study retrospectively analyzed the postoperative clinical data of patients who received artificial lens LS-313 MF15 (LS-313 MF15 group, 106 patients) and artificial lens Rayner 920H (Rayner 920H group, 164 patients) implantation in our hospital from March 2023 to July 2024. The main evaluation indicators include visual acuity at close, medium, and long distances, corrected distance vision, defocus curve, refractive error, optical quality parameters, and patient reported visual performance parameters. Among the 270 enrolled patients, 106 patients (120 eyes) were implanted with LS-313 MF15, and 164 patients (300 eyes) were implanted with Rayner 920H. The average age of the patients was 65.2 ± 10.2 years (range: 40-85 years) in the LS-313 MF15 group and 65.3 ± 12.3 years (range: 40-85 years) in the Rayner 920H group, with no significant difference (P > .05). There was no significant difference between the 2 groups in baseline parameters and postoperative refractive error. Three months after surgery, the LS-313 MF15 group showed significant improvement in both mid-range and close-range visual acuity compared to the Rayner 920H group (all P < .05). In terms of optical quality, the VF-14 scores of LS-313 MF15 is significantly better than Rayner 920H (P < .05). Two types of artificial intraocular lenses perform equally well in long-distance vision. The LS-313 MF15 group performed better in terms of mid-range and close-range vision, as well as optical quality on the VF-14 scores.
