Purpose: This study compared the extended depth of focus (EDOF) intraocular lens (IOL) (ZXR00; Tecnis Symfony, Johnson & Johnson Vision, Santa Ana, CA, US) to a novel, higher-order aspheric monofocal IOL (ICB00; Tecnis Eyhance, Johnson & Johnson Vision, Santa Ana, CA, US) which uses the same platform and material. Methods: Medical records of patients undergoing cataract surgery with ZXR00 or ICB00 implantation between March 2020 and January 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; and optical quality parameters were the main outcome measures. Results: Among the 174 enrolled patients, 72 and 102 received the ZXR00 and ICB00, respectively. The average patient ages were 59.6 ± 10.6 (range: 49 to 70) and 65.2 ± 8.2 (range: 45 to 82) years in the ZXR00 and ICB00 groups, respectively, with significantly older patients in the ICB00 group. The other baseline parameters were not different for the 2 groups. Compared to the ICB00 group, the ZXR00 group showed markedly superior near VA ( P < 0.05) at 3 months postoperatively. In terms of optical quality, ICB00 was, statistically, significantly superior to ZXR00. Conclusions: The ZXR00 showed remarkable near vision and defocus curve smoothness, while the ICB00 achieved better optical quality. The 2 IOLs had comparable distance and intermediate vision.

Purpose: To compare the lipid layer thickness (LLT), meibomian gland (MG) dropouts, and blinking pattern determined by the analysis of images acquired from the LipiView® II (LVII) and the IDRA® Ocular surface analyzer. Methods: A cross-sectional single-visit observational study was conducted. The LLT (minimum, maximum, and average), percentages of MG dropouts, and partial blink rates (PBR) were taken from both eyes of 47 participants using LVII and IDRA. Both devices were used to image the inferior eyelid of each participant in a random order. Results: Forty-seven participants (mean age 56.77 ± 14.47 (21–79) years, 66% female) completed the study. There was no significant difference in LLT between the two devices. A significant difference in percentages of MG dropouts was obtained between the LVII (36.51 ± 17.53) and the IDRA (45.36 ± 21.87), p = 0.003). There was also a significant difference in PBR between the LVII (0.51 ± 0.37) and the IDRA (0.23 ± 0.27), p < 0.001). Conclusion: No significant difference in LLT was obtained between LVII and IDRA. IDRA had a significantly lesser percentage of MG dropout and a higher PBR compared to LVII. These results indicate that these devices should not be used interchangeably for the evaluation of MG dropouts and PBR.

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.
