In the modified Yamane technique, a single-path sclerotomy with bilateral symmetry was performed instead of an angled sclerotomy. In the modified Canabrava technique, the intraocular lens was inserted first, followed by the creation of a circular polypropylene loop with 2-mm flange spacing. Postoperative refractive parameters, including intraocular lens astigmatism, and complications such as intraocular lens iris capture were analyzed.Results: Of the 88 patients, 70 underwent the modified Yamane technique, and 18 underwent the modified Canabrava technique. No significant differences were observed between the two techniques regarding refractive outcomes or postoperative complications, except for surgical duration, which was significantly shorter (p<0.001) in one technique. Mean intraocular lens astigmatism was -0.675 D for Yamane and -0.666 D for Canabrava.Conclusion: Optimizing needle engagement for symmetry in the Yamane technique and narrowing flange spacing while ensuring a circular polypropylene configuration in the Canabrava technique may reduce surgical complexity and improve postoperative outcomes.","PeriodicalId":8397,"journal":{"name":"Arquivos brasileiros de oftalmologia","volume":"89 1","pages":"e20250052"},"PeriodicalIF":1.2,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145601934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The test application was standardized using the EyeSpy algorithm. Additionally, 147 participants were tested with the standard Snellen E paper chart. Paired t tests were performed to assess the clinical significance of logMAR visual acuity differences.Results: The mean logMAR visual acuity with LEA symbols was 0.12 (standard deviation [SD]=0.18; range, -0.10 to 0.80), while with Cloudscaper symbols it was 0.18 (SD=0.19; range, -0.10 to 0.80). The mean difference between Cloudscaper symbols and LEA symbols was 0.099 logMAR (approximately 0.5 optotypes; SD=0.08; range, 0.0-0.14; p<0.0001). Cloudscaper symbols slightly underestimated visual acuity compared to LEA symbols. Visual acuity measured by both methods was highly correlated (Spearman's r=0.74, p<0.0001). The mean visual acuity difference between Cloudscaper symbols and the Snellen E chart was 0.0045 (p=0.805; 95% confidence interval [95% CI]), whereas the difference between LEA symbols and Snellen E was 0.0883 (p<0.001; 95% CI).Conclusions: Cloudscaper symbols provide a reliable tool for visual screening in children. Although they slightly underestimate visual acuity compared to LEA symbols - a finding also reported when comparing ETDRS letters with LEA symbols - Cloudscaper symbols show strong agreement with Snellen E chart measurements. This suggests that Cloudscaper symbols allow precise visual acuity assessment comparable to the gold standard.","PeriodicalId":8397,"journal":{"name":"Arquivos brasileiros de oftalmologia","volume":"89 1","pages":"e20250049"},"PeriodicalIF":1.2,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145602008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Sirius Scheimpflug imaging system was used to assess corneal topography, epithelial thickness, and non-invasive tear break-up time at baseline, 3, 6, and 12 months. Corneal warpage was evaluated using symmetry indices and Baiocchi Calossi Versaci indices. We performed statistical analysis using repeated-measures analyses of variance with Greenhouse-Geisser correction.Results: The mean baseline central corneal thickness was 537.83 (±7.92) µm, with no significant thinning after one year. The average simulated keratometry values remained stable, indicating no progressive corneal steepening or flattening. There were no significant changes in warpage indices over time, suggesting corneal shape preservation. Higher-order aberrations (coma, trefoil, and spherical aberrations) and non-invasive tear break-up time remained unchanged throughout the study period.Conclusions: Modern silicone hydrogel soft-contact lenses do not induce significant corneal warpage, epithelial remodeling, or optical aberrations over a one-year period. We found that corneal morphology and tear film stability were preserved, supporting the safety of soft-contact lens use. These findings provide clinically relevant insights into the long-term impact of contact lens wear. They may facilitate improved lens fitting strategies and preope rative refractive surgery assessments.","PeriodicalId":8397,"journal":{"name":"Arquivos brasileiros de oftalmologia","volume":"88 6","pages":"e20250118"},"PeriodicalIF":1.0,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12997644/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145298219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the initial assessment, information on screen use was gathered, and refractive error, anterior segment examination, tear breakup time, and Schirmer test measurements were conducted. Participants tracked their screen usage and break durations throughout the day. At the end of the workday, tear breakup time and Schirmer I tests were repeated. Baseline and follow-up results were compared, and regression analysis was performed to identify factors linked to tear breakup time reduction.Results: The study enrolled 60 female office employees. Their mean screen time was 269.26 ± 70.21 min, with an average break duration of 151.93 ± 46.24 min. Tear breakup time at the second assessment (6.38 ± 2.70) was significantly lower than at baseline (8.62 ± 2.73) (p<0.001), whereas Schirmer test scores showed no significant change (p>0.05). Tear breakup time reduction was noted in 54 participants (90.0%), with a significant association between tear breakup time decrease percentage and screen exposure (p=0.001, r=0.463). Regression analysis showed that uncorrected or undercorrected refractive error was an independent risk factor for a ≥30% tear breakup time reduction, while taking more frequent short breaks (<15 min) acted as a protective factor.Conclusions: Taking more frequent short breaks (<15 min) and correcting refractive errors help prevent intra-day tear breakup time decline during visual display terminal use.

The included participants were followed up for at least 24 months, and only one surgeon performed all the procedures. The number of glaucoma medications, pre- and postoperative intraocular pressure, treatment extension (in quadrants), surgical complications, and any associated events or interventions were documented.Results: This study included 13 eyes from 10 patients (mean age, 4.5 ± 3.2 years; range, 3 months to 10 years). After a 24-month follow-up, the mean intraocular pressure significantly decreased from 26.1 ± 3.7 to 11.8 ± 2.5 mmHg (p<0.001). The mean number of glaucoma medications was reduced from 3.3 ± 0.5 to 0.85 ± 1.0 (p<0.001).
