Purpose: To assess the clinical outcomes and patient satisfaction of the Tecnis Eyhance, an advanced monofocal intraocular lens (IOL), compared to a conventional monofocal IOL. Design: Retrospective case-control study. Methods: This study included 120 eyes of 60 patients (30 patients in each group) who underwent bilateral cataract surgery either with the implantation of conventional monofocal IOLs (Tecnis PCB00), as a control group, or advanced monofocal IOLs (Tecnis Eyhance ICB00). Ophthalmological evaluation included the measurement of binocular corrected distance visual acuity (CDVA), monocular and binocular uncorrected distance visual acuity (UDVA), and uncorrected intermediate VA (UIVA). In addition the binocular defocus curve was analyzed. Furthermore a subjective questionnaire (Catquest-9SF) was used to assess vision and life quality. Results: The average binocular UDVA was 20/22 in the ICB00 group and 20/20 in the PCB00 model ( p = 0.62). The average monocular UIVA was 20/32 in the ICB00 group and 20/40 in the control group ( p < 0.001). We found the binocular UIVA, had a mean value of 20/30 in the ICB00, compared to 20/40 in the control group ( p < 0.001). The reported dysphotopsia was not significantly different between both groups ( p = 0.56). Regarding the life quality questionnaire, the ICB00 group showed less difficulty in activities requiring intermediate vision. Conclusion: Our results demonstrated a significant improvement in visual acuity for intermediate distance in the ICB00 group compared to the control group, without compromising distance visual acuity. We also found a greater capability for intermediate distance activities (namely for computer use and reading price tags) when comparing ICB00 patients with the control group.

Introduction and Objective To evaluate corneal epithelial thickness (ET) and corneal thickness (CT) profiles in healthy eyes of Portuguese children and provide information to establish the first normative Caucasian database for these age group. Methods Sixty healthy eyes of 60 children aged between 8 and 18 were evaluated using the Cirrus high-definition optical coherence tomography device. The average ET and CT were assessed using Cirrus Review Software with predefined concentric corneal ring-shaped zones. Specific regions of ET (central, superior, inferior, temporal, nasal, superonasal, inferotemporal, superotemporal and inferonasal) were also assessed. The mean ET, the mean CT and the difference of ET in corresponding octants were compared by gender. Correlations between central epithelial thickness (CET), age and refractive error were evaluated. Results and Discussion The average ET was lower in the peripheric zones, whereas the average CT was higher. ET was thinner in the superior area than in the inferior (p<0.05). ET was thicker in boys than in girls (p<0.05), but CT did not differ. CET was not correlated with older age or refractive error. Conclusion Optical coherence tomography analysis of ET reveals that it is thinner in the periphery, where the CT is thicker. Unlike CT, ET seems to be influenced by gender. ET profile proved to be a useful tool in keratoconus diagnosis and subclinical keratoconus detection in adults. As epithelial changes occur early in the disease and keratoconus is more aggressive in pediatric population, a normative database of ET profile could contribute to enhance early recognition of the disease in this age group.

Purpose To assess the preliminary clinical outcomes and patient satisfaction of the new enhanced depth of focus (EDOF) LuxSmart™ intraocular lens IOL and to compare with a conventional monofocal IOL (Akreos™) in patients who had undergone bilateral cataract surgery. Methods Twelve patients underwent bilateral LuxSmart IOL implantation, and twelve underwent bilateral Akreos IOL implantation. Best-corrected distance (CDVA) and uncorrected distance visual acuity (UDVA), uncorrected intermediate visual acuity (UIVA) at 66cm, uncorrected near visual acuity (UNVA) at 40cm and defocus curve were assessed. Patients-reported visual function was inquired by Catquest-9SF. The presence of photic phenomena was evaluated. A p-value lower than 0.05 was considered for statistical significance. Results The mean IOL power was +21.90D in LuxSmart group and +22.30D in Akreos. Monocular UDVA (p = 0.32) and CDVA (p = 0.52) did not differ between groups. The average binocular UIVA (0.18 ± 0.12 logMAR vs. 0.30 ± 0.13 logMAR, p < 0.001) and UNVA (0.38 ± 0.14 logMAR vs. 0.44 ± 0.17 logMAR, p = 0.02) were higher in LuxSmart IOL group. No patients reported disabling photic phenomena in either group. Conclusion This study shows that new LuxSmart EDOF IOL achieved higher performance for intermediate and near vision compared with a conventional monofocal IOL, without increasing the risk of dysphotopsias. LuxSmart may be an attractive and safe option for patients who desire spectacle independence for distance and intermediate vision after cataract surgery.

Purpose: To assess long-term vascular density measured by optical coherence tomography angiography (OCT-A) in former preterm children with history of retinopathy of prematurity (ROP) with and without need of laser treatment. Methods: This observational study included former preterm children that developed ROP stage 2 or 3. Infants were divided in two groups according to previous need of laser treatment, and underwent a complete ophthalmologic evaluation, including assessment of macular morphologic and vascular parameters by OCT-A. Results: Fifteen eyes were included in group 1 (laser-requiring ROP) and 19 in group 2 (non-treated ROP). Group 1 had lower mean gestational age and birth weight values than group 2 ( p < 0.001 and p < 0.001, respectively). Best corrected visual acuity (BCVA) was lower in group 1 (0.08 ± 0.04 logMAR vs 0.04 ± 0.07 logMAR, p = 0.03). Laser-requiring ROP had lower vascular parameters, especially of central and internal vascular density (9.15 ± 2.75 vs 10.52 ± 0.86 mm−1, p = 0.05; 13.74 ± 1.00 vs 15.86 ± 0.64 mm−1, p = 0.05; respectively), and lower avascular zone circularity (0.58 ± 0.06 vs 0.76 ± 0.02, p < 0.001). Mean macular thickness was higher in group 1 (300.50 ± 10.50 vs 281.11 ± 2.50 μm, p = 0.05). Best corrected visual acuity (BCVA) was correlated with superficial vascular density ( p < 0.05). Conclusion: Laser-requiring ROP seems to result in a decrease of long-term BCVA, which is at least partially attributed to a decrease in superficial macular vascular density. However, prematurity degree was more pronounced in children that required treatment, which might have influenced our results.
