Exploratory Analysis of Glaucoma-Associated SNPs in a Colombian Cohort Highlights Potential Involvement of Oxidative, Vascular, and Neurodegenerative Pathways.

Casanova Carlos C, Valencia-Peña Claudia C, Saldarriaga-Gil Wilmar W, Lozano-Cruz Edgar E et al.

Primary open-angle glaucoma (POAG) is a complex multifactorial optic neuropathy involving genetic, vascular, oxidative, inflammatory, and neurodegenerative mechanisms. Despite advances in genome-wide studies, the contribution of genetic variants remains incompletely characterized in underrepresented Latin American populations. This study aimed to characterize the genetic landscape of POAG in a Colombian cohort by identifying previously reported glaucoma-associated variants, rare candidate variants, and pharmacogenomic markers and integrating these findings into biologically relevant pathways. An exploratory descriptive study was conducted in 21 Colombian patients with confirmed POAG. Whole-exome sequencing (WES) was performed at an average sequencing depth of approximately 100×. Variants were quality-filtered, functionally annotated, and prioritized within 446 POAG-associated genes retrieved from DisGeNET. Previously reported glaucoma-associated variants and rare candidate variants were identified, while pharmacogenomic variants related to latanoprost and timolol response were evaluated using ClinPGx/PharmGKB. Identified genes were classified according to major biological pathways relevant to glaucoma pathophysiology. Of the 446 POAG-associated genes, 381 were detected in the patients' exomes. A total of 10,220 molecular variants were identified, of which 1,187 synonymous variants were excluded, leaving 9,033 variants for downstream analysis. Among these, 955 were non-synonymous SNVs, including 26 variants previously reported in association with glaucoma and 929 potentially novel coding variants. Previously reported variants included loci in SIX6, LOXL1, CYP1B1, NOS3, and SOD2. Two rare candidate variants (minor allele frequency <1%) were identified in FMNL2 and C3. Pharmacogenomic variants in PTGS1, ADRB1, and ABCC4 with potential implications for response to latanoprost or timolol were also detected. Functional integration highlighted pathways involving oxidative stress, extracellular matrix remodeling, vascular regulation, neurodegeneration, and inflammation. This exploratory analysis identifies known glaucoma-associated variants, rare candidate variants, and pharmacogenomic markers in Colombian patients with POAG. The findings support a multifactorial biological framework involving interconnected oxidative, structural, vascular, neurodegenerative, and inflammatory pathways. The FMNL2 and C3 variants represent candidates for further investigation, while the identified pharmacogenomic variants highlight the potential relevance of genomic profiling for personalized glaucoma management. Larger ancestry-informed case-control studies are required to validate these observations and determine their clinical significance.

Optical Quality Degradation Following Nd:YAG Laser-Induced Intraocular Lens Pitting: A Multimodal Experimental Study.

Luca Laura De L, Menna Feliciana F, Lupo Stefano S, Ruello Elisa E et al.

Nd laser posterior capsulotomy is the standard treatment for posterior capsule opacification following cataract surgery. Although generally considered safe, inadvertent laser impacts on the intraocular lens (IOL) optic may induce permanent surface defects that contribute to postoperative dysphotopsias and reduced visual quality. This experimental study investigated the optical consequences of Nd laser-induced damage on two commercially available hydrophobic acrylic IOLs, focusing on retinal light distribution and optical image quality. Two hydrophobic acrylic monofocal IOL models, the CT LUCIA (Carl Zeiss Meditec) and the AcrySof IQ (Alcon), were mounted on a customized experimental holder and exposed to standardized Nd laser applications consisting of 5, 10, or 15 laser shots. Laser interactions were documented using the PhysioGo.Lite laser platform combined with infrared thermal imaging. Untreated IOLs served as controls. Optical performance was subsequently evaluated using a standardized optical bench according to ISO recommendations. Point spread function (PSF) and modulation transfer function (MTF) analyses were performed to quantify retinal image quality, light scattering, and optical degradation. Retinal light distribution was assessed using a high-resolution projection screen simulating the retinal image. Laser exposure produced permanent focal defects on the anterior optical surface of both IOL models, resulting in measurable optical degradation. Even the lowest laser exposure (five shots) generated detectable alterations in light propagation, characterized by increased peripheral light scattering, enlargement of the PSF halo, reduced central peak intensity, and irregular light distribution across the simulated retinal plane. Descriptively, increasing numbers of laser impacts were associated with more pronounced optical disturbances, particularly in the AcrySof IQ samples. MTF analysis demonstrated a reduction in optical performance across multiple spatial frequencies, indicating deterioration of image contrast and resolving power. Although both hydrophobic acrylic IOL models exhibited optical alterations after laser exposure, descriptive differences in the magnitude and distribution of light scatter suggested a possible influence of material composition, refractive index, and surface microarchitecture. These observations should be considered preliminary because of the limited sample size and absence of inferential statistical analysis. Under the present experimental conditions, Nd:YAG laser-induced pitting was associated with measurable structural and optical alterations in two hydrophobic acrylic IOL models. Surface defects alter retinal light distribution, increase forward light scatter, and reduce optical quality, providing a possible optical mechanism that may contribute to postoperative dysphotopsias, although clinical visual symptoms were not directly evaluated in this study. These findings highlight the importance of meticulous laser focusing on the posterior capsule to minimize inadvertent IOL damage and preserve postoperative visual quality. Further investigations combining optical bench analyses with patient-reported visual outcomes are warranted to better define the clinical significance of laser-induced IOL pitting.

Posterior capsular rupture and phacoemulsification device.

Ahmed Mahmoud M, Passaro Maria Laura ML, Kaye Stephen B SB

To investigate whether phacoemulsification platform type and phaco tip design are associated with differences in unadjusted posterior capsular rupture (PCR) rates in cataract surgery. This retrospective observational study used centre-level data from UK National Health Service (NHS) cataract surgery centres included in the 2024 National Ophthalmology Database Cataract Audit, with a complementary analysis from two tertiary NHS centres. Phacoemulsification platform and principal tip design were identified by contacting each centre. Unadjusted PCR rates were compared using χ² tests with ORs and 95% CIs. A separate eye-level analysis assessed the association between tip design and PCR after adjusting for surgeon experience. Twenty-four NHS centres contributed 166 213 cataract operations, with a mean unadjusted PCR rate of 1.48% (SD 0.61%). Among 44 202 procedures, Alcon systems accounted for 25 921 cases with 462 PCRs (1.78%), while Bausch & Lomb systems accounted for 18 281 cases with 202 PCRs (1.10%) (OR 1.62, 95% CI 1.38 to 1.92; p<0.0001). Flared tips were associated with higher unadjusted PCR rates than straight tips (2.12% vs 1.30%; OR 1.64, 95% CI 1.40 to 1.93; p<0.0001). In the local eye-level cohort, flared tips remained associated with higher odds of PCR after adjustment for surgeon experience (OR 2.33, 95% CI 1.18 to 5.13). In this national audit sample, phacoemulsification platform and tip architecture were associated with differences in unadjusted PCR rates. Similar associations were observed in a complementary eye-level analysis adjusting for surgeon experience. Given the unadjusted nature of the data and the lack of adjustment for case complexity, surgical technique, training and fluidics configuration, these findings should be interpreted with caution, and further prospective risk-adjusted studies are needed.

Comparison of manual marking and femtosecond laser-assisted capsular marking methods for toric intraocular lens alignment.

Dinc Dincer D

To compare the effectiveness of femtosecond laser-assisted capsular marking and manual slit-lamp marking methods in correcting astigmatism during cataract surgery, for accurate positioning of toric intraocular lenses (IOLs). The medical records of 35 eyes that underwent preoperative manual marking with implantation of AcrySof IQ PanOptix (Alcon Laboratories, Fort Worth, TX) toric trifocal lens (Group 1), and 35 eyes that underwent the same toric trifocal lens implantation using femtosecond laser IntelliAxis software (Group 2), between 2019 and 2024, were retrospectively reviewed. Pre- and postoperative uncorrected and corrected visual acuity, preoperative corneal astigmatism, postoperative residual astigmatism, and slit-lamp and fundus examinations were evaluated. In the manual-marking group, the mean preoperative corneal astigmatism was 2.11 ± 0.66 D, while the postoperative astigmatism was 0.51 ± 0.17 D. In the femtosecond laser marking group, the mean preoperative corneal astigmatism was 2.06 ± 0.61 D, and the postoperative astigmatism was 0.38 ± 0.13 D. Both groups demonstrated a statistically significant reduction in astigmatism values before and after surgery ( P < 0.05). Postoperative residual astigmatism was lower in the femtosecond group, and the difference between the two groups was statistically significant ( P < 0.05). Both femtosecond laser-assisted and manual-marking methods are effective techniques for toric lens alignment. However, the femtosecond laser-assisted method was found to be statistically superior in correcting astigmatism. Additionally, femtosecond laser marking offers several advantages over manual marking. It is less surgeon-dependent, requires less experience, shortens the procedure time, and eliminates ink-related complications during surgery.

From Earlier to Updated Quadrifocal Intraocular Lens Designs: An Objective Optical Metrology Analysis.

Jeong Eun Ah EA, Bang Seung Pil SP, Pantanelli Seth S, Kang Su Jin SJ et al.

To compare the optical performance of the Clareon PanOptix and Clareon PanOptix Pro intraocular lenses (IOLs) using interferometric metrology and identify measurable optical differences. Physiological Optics Laboratory, Daegu, Republic of Korea. Experimental optical-bench investigation. Three +20.0 D samples each of the PanOptix and PanOptix Pro IOLs (Alcon) were analyzed using a Mach-Zehnder interferometer in a model eye incorporating +0.27 µm corneal spherical aberration. Microscopic imaging, wavefront reconstruction with Zernike analysis, diffractive-step profile reconstruction, point-spread function (PSF)-based retinal image simulation, halo analysis, and through-focus modulation transfer function (TF-MTF) analysis were performed. Both IOLs showed broadly similar diffractive architecture and spherical aberration profiles. Peak-to-valley step-profile amplitudes were comparable, although the PanOptix Pro showed localized differences in the reconstructed step-height contour. PSF-based analyses showed broadly similar focal behavior, but the PanOptix Pro demonstrated clearer Sloan F contour preservation and more evident central PSF-core brightness at the far-intermediate position. In through-focus average MTF (aMTF) profiles, the PanOptix Pro showed a modestly higher far-focus peak and a less pronounced post-peak dip, particularly at 4.5- and 3.0-mm pupils. MTF50 analysis showed a similar overall pattern, with greater variability and more apparent inter-model differences at larger pupil sizes. The PanOptix Pro preserves the fundamental design and spherical aberration profile of the original PanOptix, while showing localized diffractive step-height modifications. Together with clearer far-intermediate F-image preservation, sustained central PSF-core brightness, and a shallower post-peak aMTF dip, these findings are consistent with a relative redistribution of optical energy toward the far-intermediate region, supporting greater far-intermediate optical continuity without substantial changes in nominal add power or overall focal structure.

Straylight-Based Evaluation of Glare in Two Presbyopia-Correcting Intraocular Lenses.

Kremser Frederick F, Łabuz Grzegorz G, Zielińska Agnieszka A, Khoramnia Ramin R et al.

BACKGROUND: Presbyopia-correcting intraocular lenses (IOLs) provide a complete spectrum of vision but frequently induce dysphotopsia due to multiple focal points and diffractive designs. Standard straylight assessments using a C-Quant meter at a 7° visual angle often show no significant differences between evaluated IOLs. Therefore, evaluating glare effects effectively requires device modifications to demonstrate differences across lower visual angles. This study evaluates glare from the diffractive designs of two presbyopia-correcting IOLs. MATERIAL AND METHODS: This in vitro laboratory study assessed two IOL models: the Clareon PanOptix (Alcon) and the Tecnis Odyssey (J&J Vision). Straylight was measured using a modified C-Quant straylight meter, allowing evaluation at the standard 7° angle as well as lower angles of 2.5° and 3.5°. RESULTS: At 7°, the Clareon PanOptix exhibited straylight of 0.29 ± 0.19 deg2/sr, while the Tecnis Odyssey showed an 8-fold higher value of 2.29 ± 0.60 deg2/sr. At 3.5°, the Clareon PanOptix measured 3.01 ± 0.88 deg2/sr, whereas the Tecnis Odyssey demonstrated more than twice the magnitude at 6.85 ± 0.68 deg2/sr. At the smallest angle of 2.5°, the Clareon PanOptix recorded 4.57 ± 0.12 deg2/sr. In contrast, the Tecnis Odyssey reached 9.34 ± 0.41 deg2/sr, approaching the reference value of a 65-year-old natural crystalline lens. CONCLUSION: The Clareon PanOptix demonstrated substantially lower straylight values across all measured angles compared with the Tecnis Odyssey. This suggests a reduced potential for glare phenomena. Further research using validated patient-reported questionnaires is needed to correlate these objective findings with subjective visual disturbances. QUINTESSENCE: in vitro straylight testing shows that the Clareon PanOptix IOL exhibits lower straylight levels than the Tecnis Odyssey across all measured angles. While clinical confirmation is needed, these findings suggest that the Clareon PanOptix may be associated with a lower risk of dysphotopsia related to its diffractive design.
