Abstract:
AIM: To evaluate the visual function and optical quality in adults aged 80y and older following the bilateral implantation of zonal refractive multifocal intraocular lens(IOL, LS-313 MF30).METHODS: A single-center, non-randomized, prospective clinical trial was conducted, involving cataract patients aged 80 y and older. Patients received bilateral implantation of the LS-313 MF30 or CT Asphina 409MP, based on personal preference. Postoperative assessments included uncorrected and corrected visual acuity at distance, intermediate, and near ranges, as well as defocus curve. Subjective evaluations were performed using the visual function(VF-14)questionnaire, spectacle independence rates, and patient satisfaction surveys. Photic phenomena such as glare, halos, and starbursts were also analyzed.RESULTS: The MF30 group(16 eyes from 8 participants, 85.38±2.56 y)exhibited superior uncorrected and corrected intermediate and near visual acuity compared to the 409MP group(26 eyes from 13 participants, 85.77±2.20 y), while distance visual acuity was comparable between groups. The defocus curve of the MF30 group revealed two peaks at 0.00 D and -3.00 D, indicating a broader depth of focus. Patients in the MF30 group reported higher rates of spectacle independence and greater satisfaction. While photic phenomena such as glare(28.6% vs 18.5%, P=0.584), starburst(9.5% vs 3.7%, P=0.567)and halos(23.8% vs 11.11%, P=0.438)were more prevalent in the MF30 group, they were generally mild and did not significantly impact daily activities.CONCLUSION: Zonal refractive multifocal IOLs provide elderly patients with improved distance and near vision, greater spectacle independence, and greater satisfaction. Although photic phenomena were slightly more frequent with MF30, they are generally reported as non-disruptive and do not affect their daily life compared to monofocal IOLs.
