“…ZXR00 IOL is transparent with nine diffractive rings, while ZFR00 IOL is white wine colored with 15 diffractive rings. 11 The average height of the 15 diffractive rings on the ZFR00 IOL is like that of the ZXR00 IOL, but the height of the diffractive rings varies more in ZFR00 IOL. 12 This study was designed to compare the visual results and optical qualities of the two IOLs.…”

Purpose This study compared the extended depth of focus (EDOF) intraocular lens (IOL) (ZXR00; Tecnis® Symfony®, Johnson & Johnson Vision, Santa Ana, CA, USA) and a new presbyopia-correcting IOL that combines EDOF and multifocal profiles (ZFR00; Tecnis® Synergy®, Johnson & Johnson Vision, Santa Ana, CA, USA) with the same material. Methods The medical records of patients undergoing cataract surgery with ZXR00 or ZFR00 implantation between March 2021 and July 2021 and with the data available for the 3-month visit were reviewed. The uncorrected near, intermediate, and distance visual acuity (VA), corrected distance VA, defocus curves, refractive errors (RE), optical quality parameters, and patient-reported visual performance parameters were the main outcome measures. Results Among the twenty-three enrolled patients, twelve patients (21 eyes) received ZXR00 and nine patients (17 eyes) received ZFR00. The mean age of the patients was 59.6 ± 10.6 (range: 49 to 70) and 65.2 ± 8.2 (range: 45 to 82) years in ZXR00 and ZFR00 groups, respectively, without significant difference. There was not a significant difference between the two groups in terms of baseline parameters and postoperative RE. The ZFR00 group showed markedly superior intermediate and near VA ( p < 0.001 for all) at 3 months postoperatively. In terms of optical quality, ZXR00 was significantly better than ZFR00 ( p < 0.001). Conclusions Both IOLs had comparable distance VA. ZFR00 IOL was superior for intermediate and near visual acuity, but ZXR00 IOL was better for optical quality. Research with more participants is needed to support this finding.

“…Keratoconus progressively degrades the corneal shape and, consequently, vision in adolescence, with a prevalence of 0.05% in the general population. (11) Standard IOLs are mostly designed for long-distance vision. Although accommodative IOLs have been proposed, the current designs only provide a modest range of accommodation in the best-case scenario.…”

A complex intraocular lens (IOL) design involving numerous uncertain variables is proposed. We integrated a genetic algorithm (GA) with a freeform surface lens by using CODE V optical design software to design a multifocal IOL for the human eye. We mainly used a freeform surface lens of acrylic material in the initial crystalline state to enhance image sensing quality; therefore, we used the internal human eye model in the software. The proposed optimization algorithm employs a GA method to optimally simulate the focusing function of the human eye; in this method, the thickness and curvature of the anterior lens and the posterior part of the IOL were varied. We performed a comparison of the proposed GA-designed IOLs and those designed using a CODE V built-in optimization algorithm for the hyperopia 300 degree condition of the human eye. When the pupil entrance was 6 mm, the proposed IOL design improved the RMS of the spot diagram by approximately 11.99 and 10.65% for the human eye to object distances of 35 cm and infinity, respectively. Moreover, the modulation transfer function (MTF) was improved by approximately 5.06 and 15.06% for distances of 35 cm and infinity at a spatial frequency of 15 cycles/mm, respectively.
