Measurements, including axial length (AL), anterior chamber depth (ACD), and lens thickness (LT), were compared. SpikeFinder was applied to eyes with the most prominent ACD and LT measurement differences. Statistical testing was performed using Wilcoxon (two variables) and Kruskal-Wallis ANOVA tests (multiple variables) with Tukey post-hoc adjustments. Heteroscedastic testing (WHWK Statistics Package) was used to assess differences after software application.Results: 99.1% of AL measurements were within 0.01 mm between the two biometers. SS-OCT LT was significantly longer than the OLCR LT: 33% differed by ≥ 0.50 mm (p<0.001). Correspondingly, SS-OCT ACD was significantly shorter than OLCR ACD: 14% differed by ≥ 0.50 mm (p<0.001). SS-OCT biometer - OLCR biometer values for ACD and LT before applying SpikeFinder were -0.64 ± 0.31 mm and 1.15 ± 0.38 mm, respectively (p<0.001). After applying SpikeFinder to a subgroup of 337 eyes, these differences were -0.02 ± 0.03 mm and 0.01 ± 0.11 mm, respectively. SpikeFinder ACD and LT values were similar to SS-OCT biometer-measured ACD (p=0.872) and LT (p=0.987) values.Conclusion: The SpikeFinder program can help improve the accuracy of ACD and LT measurements obtained by the OLCR biometer, which may enhance the performance of formulas that utilize these measurements.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AS INTRASEG features an arc length of 150 degrees and asymmetric width (800 to 1200 µm). Anterior segment optical coherence tomography (AS-OCT) combined with Placido disc MS-39 (CSO, Firenze, Italy) were performed before, 1, and 6 months after surgery to assess keratometric, aberrometric outcomes, and epithelial remodeling. Refractive outcomes were also evaluated. Analysis of the correction profile according to the width of the base of the ICRS was performed.Results: 43 keratoconic eyes were analyzed. Significant improvement of corrected distance visual acuity was observed (LogMAR): from 0.34 ± 0.23 to 0.08 ± 0.10 (p<0.001). The flattening effect was higher at the widest end than the narrowest end (-10.59D ± 2.59 versus -4.54D ± 1.30, p<0.001), contributing to reduce the Symmetry Index Front from 9.06 ± 4.02 to 2.21 ± 3.81.

Setup without running fluidics to produce air bubbles inside the system. 2. Circulation fluidic setup to compare measurements with and without cataractous lens material. 3. A surgery-comparable system that closely mimics a realistic setup.Porcine lenses were incubated for 1.25h in formalin to simulate middle hard cataracts and emulsified in a test chamber. Free radicals were captured by the spin-trapping agent 5,5'-dimethyl-1-pyrroline N-oxide and measured using electron-paramagnetic resonance spectroscopy.Results: Hydroxyl-radicals were the predominant free radicals detected. The maximum amount of radicals was produced when air bubbles were allowed to build up inside the system. Less radicals were produced during lens-emulsified compared to application without lens. This effect was enhanced when the phacotip was in close contact with the lens during the whole procedure. In the surgery-comparable setup, the least amount of free radicals was detected.Conclusion: For the first time we were able to analyze free radicals during phacoemulsification of lens-tissue. We show that emulsification of lens tissue reduces the production of free radicals, an effect that is enhanced during close contact of the tissue with the phacotip. Also, we show that air-bubbles should be avoided during cataract surgery, as they may enhance free radical production. Furthermore, running fluidics remove most of the radicals making oxidative stress less likely.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143399269","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Correlation between the measured value of axial length, corneal diameter, age, and bag diameters and their effect on Intraocular Lens (IOL) implantation (Aphakia/Pseudophakia) were observed.Results: We included 112 eyes of 68 children with a mean age of 11.42 + 11.34 months ( 1 month - 4 years). Mean capsular bag diameter(CBD) in the eyes where IOL was placed successfully in the bag was 8.27 ± 0.6 mm (7.1 - 9.39 mm). The eyes in which IOL placement was difficult in the bag and who were either left aphakic or bicapsular capture IOL was performed had a mean diameter of 7.09 ±0.99 mm (5.23 - 9.09 mm) (p<0.05).

Exclusion criteria were sulcus IOL placement, subsequent intraocular or refractive surgery in the operative eye, and 5-year Snellen visual acuity of 20/60 or worse. Outcomes of interest were change in spherical equivalent and change in magnitude of the astigmatism vector between the postoperative month 1 and postoperative year 5 refractions. Refractive stability was defined as ≤0.5D change in spherical equivalent and ≤1D change in magnitude of the astigmatism vector.

To perform an external validation a dataset of 45 observations was used.Results: The Pearson correlation coefficient between observed and predicted values was similar in the five models in the external validation, with least absolute shrinkage and selection operator (LASSO) regression being the highest (r = 0.62, p < 0.001), followed by random forest regression model (r = 0.60, p < 0.001) and backward stepwise regression (r = 0.58, ρ < 0.001). In addition, the predictions generated by the different models showed closer agreement with the actual vault compared with the Nakamura formulas. Using the new methods, about 70% of the observations had a prediction error below 150 µm.Conclusions: Advanced forms of regressions models based on machine learning allow satisfactory calculation of the ideal lens size, offering greater precision to surgeons customizing surgery according to implant orientation.","PeriodicalId":15214,"journal":{"name":"Journal of cataract and refractive surgery","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143065820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
