ABSTRACT
This study aimed to compare the postimplantation clinical outcomes of 2 types of posterior chamber phakic intraocular lenses (IOLs): Visian™ implantable collamer lenses (ICL; EVO+ V5; Staar Surgical, Monrovia, CA) and an implantable phakic contact lens (IPCL) (IPCL V2.0, Care Group Sight Solution, India) to correct high myopia and myopic astigmatism. This retrospective study included patients who had undergone phakic IOL implantation performed by a single surgeon between March 2021 and March 2022. Preoperative assessments included slit-lamp examination, fundus examination, spherical equivalent, uncorrected distant visual acuity (UDVA), corrected distant visual acuity (CDVA), specular microscope parameters, and optical quality analysis system parameters. Postoperative assessments after 1 year included slit-lamp examination to detect adverse effects and spherical equivalent, UDVA, CDVA, specular microscope, optical quality analysis system, and anterior-segment optical coherence tomography. Eighty eyes from 42 patients (47 eyes from 24 patients in the ICL group and 33 eyes from 18 patients in the IPCL group) were included. No statistically significant differences were observed between the 2 groups regarding preoperative parameters. At 1-year postoperatively, the mean UDVA in the ICL and IPCL groups was 0.019â ±â 0.040 logMAR and 0.019â ±â 0.041 logMAR, respectively. The mean CDVA was 0.001â ±â 0.008 logMAR and 0.001â ±â 0.007 logMAR in the ICL and IPCL groups, respectively, showing no statistically significant differences. The postoperative parameters did not differ significantly between the 2 groups. The visual acuity and refractive results of both groups were excellent, and both groups exhibited similar efficacy and safety profiles.

This study examined the link between fatty liver disease (FLD) and cataracts, as previous research has suggested that FLD may contribute to metabolic syndrome, systemic inflammation, and potentially cataracts. We studied a nationwide cross-sectional cohort of the Fifth Korean National Health and Nutrition Examination Survey 2010-2011. FLD was defined as nonalcoholic FLD (NAFLD) and metabolic dysfunction-associated FLD (MAFLD). Multinomial logistic regression was utilized to investigate the relationship between cataracts and FLD after adjustment for potential confounders. Participants with cataracts had higher liver fibrosis scores, including the NAFLD fibrosis score (NFS; P < 0.001), fibrosis-4 index (FIB4; P < 0.001), and fatty liver index (FLI; P = 0.001). NAFLD was not associated with a higher odds ratio (OR) for cataracts in the fully adjusted model (OR = 1.23, P = 0.058). MAFLD was significantly associated with a higher OR (OR = 1.34, P = 0.006). After adjusting for all factors, the severity of FLD was linked to an increased risk of cataracts, with significant linear trends (P values for linear trends of NFS, FIB4, and FLI < 0.05). After adjusting for well-known cataract risk factors, MAFLD was significantly associated with cataracts. Our analysis suggests that FLD may serve as an independent risk factor for cataracts.

Purpose: To compare the effectiveness of intravitreal injections of brolucizumab and aflibercept in patients with polypoidal choroidal vasculopathy (PCV). Methods: In total, 62 treatment-naive PCV eyes (62 patients) treated with intravitreal brolucizumab or aflibercept were analyzed retrospectively. All patients received a monthly loading injection of antivascular endothelial growth factor for 3 months, followed by further injections as required. Visual and anatomical outcomes were compared between drugs after 12 months of treatment. Results: The improvement in best-corrected visual acuity after 12 months of treatment was not significantly different between the brolucizumab-treated (22 eyes) and aflibercept-treated groups (40 eyes). However, in the brolucizumab-treated group, there was a significantly greater decrease in central retinal thickness (172 vs. 147 µm; P = 0.031) and subfoveal choroidal thickness after treatment (51 vs. 29 µm; P = 0.025). In addition, the regression rate of polypoidal lesions was significantly higher in the brolucizumab-treated group (77.3%, 17/22 eyes) than that in the aflibercept-treated group (45.0%, 18/40 eyes; P = 0.014). Sterile intraocular inflammation showing mild vitritis was observed in 1 of the 22 eyes (4.5%) of brolucizumab-treated patients. Conclusion: Intravitreal brolucizumab injections for PCV showed visual improvement comparable to that of aflibercept during the 12-month treatment period. However, brolucizumab was more effective than aflibercept for the regression of polypoidal lesions and caused a greater decrease in central retinal thickness and subfoveal choroidal thickness.

OBJECTIVE: To assess and compare the visual performance of two extended depth-of-focus intraocular lenses (IOLs), Tecnis Symfony (Symfony; Johnson & Johnson Vision, Santa Ana, CA) and Acrysof IQ Vivity (Vivity; Alcon Inc, Fort Worth, TX). METHODS: The medical records of patients undergoing cataract surgery with Symfony or Vivity implantation from May 2021 to September 2021 and the data available for the 3-month follow-up were reviewed. The main measures of the findings were uncorrected and corrected distance (4 m) visual acuity (VA), uncorrected intermediate (66 cm) VA (UIVA) and uncorrected near (40 and 33 cm) VA (UNVA), refractive error (RE), defocus profiles analysis, optical quality parameters, and patient-reported quality of vision questionnaire results. RESULTS: Of the 40 patients, 19 patients (31 eyes) were treated with the Symfony IOL and 21 (32 eyes) with the Vivity IOL. The mean age of the patients was 63.4±7.8 (range, 40-76) years in the Symfony group and 61.8±9.7 (range, 40-77) years in the Vivity group. There was no meaningful difference between the two groups in the preoperative parameters, except that the Vivity group had a better CDVA. Among the main measures of results, there was no statistically significant difference, except for the UNVA (33 cm). The Symfony group also showed a smoother defocus curve at 3 months postoperatively. CONCLUSION: There was no significant difference between the two groups regarding uncorrected/corrected distance VA, UIVA, UNVA (40 cm), RE, optical quality parameters, and patient-reported quality of vision questionnaire results. The Symfony group demonstrated a significantly superior UNVA (33 cm) and a smoother defocus curve with a broad landing zone.

OBJECTIVE: To compare corneal endothelial cell changes after femtosecond laser-assisted cataract surgery (FLACS) in diabetic and nondiabetic patients. METHODS: This retrospective study included patients with cataract who underwent FLACS performed by a single surgeon between August 2018 and November 2020. Changes in corneal endothelial cell density (ECD), hexagonality, coefficient of variation in cell size (CV), and central corneal thickness (CCT) at baseline and at the 1-month and 3-month postoperative follow-ups were investigated by dividing the patients into diabetic and nondiabetic groups. RESULTS: We included 75 patients (60% men, mean age: 57.7±11.4 years, range: 27-80 years) in the analysis: 31 diabetic patients (64% men, mean age: 58.7±11.9 years, range: 27-79 years) and 44 nondiabetic patients (56% men, mean age: 57.1±11.3 years, range: 34-80 years). No differences were observed between the two groups as regards preoperative and intraoperative parameters, the mean postoperative ECD, hexagonality, and CV. At 1 month postoperatively, the CCT was significantly greater in the diabetic group (P=0.034); however, at 3 months, there was no significant difference between the two groups (P=0.927). CONCLUSIONS: Changes in postoperative corneal endothelial cells were comparable between patients with and without diabetes after FLACS. Femtosecond laser-assisted cataract surgery seems to cause less damage to the corneal endothelium in diabetic patients because it uses less phacoemulsification energy.

PURPOSE: To evaluate the performance of two intraocular lenses (IOLs). The new monofocal IOL using a higher-order aspheric optic (Tecnis Eyhance ICB00) was compared to a standard monofocal IOL (Tecnis monofocal ZCB00) of the identical platform and material. METHODS: The medical records of the patients who had undergone cataract surgery with implantation of either the ZCB00 or the ICB00 in the dominant eye from March 2020 to August 2020 and with available data from the 3-month visit were reviewed. Subjects with ocular comorbidities or corneal astigmatism greater than 1.00 diopters were excluded. The uncorrected near, intermediate, distance visual acuity and corrected distance visual acuity were the main outcome measures. Optical quality parameters measured using an optical quality analysis system, clinical records including age, sex, laterality, ocular dominance, and information related to refractory errors was also collected. Parameters related to the refractory errors were all uniformly based on the Barrett Universal II formula. RESULTS: Of the 197 recruited patients, 111 and 86 were implanted with the ICB00 and ZCB00, respectively. No statistically significant differences in baseline parameters were observed between the two groups. While no statistically significant differences in distance visual acuity or optical quality were found between the two groups, compared to the ZCB00 group, the ICB00 group showed significantly higher intermediate visual acuity (p < 0.001) and near visual acuity (p < 0.05) 3 months postoperatively. CONCLUSIONS: ICB00 provided superior intermediate vision and comparable distance performance and photic phenomena compared to a standard monofocal IOL.
