Design: This is a retrospective consecutive case series. Methods: From all uneventful phacoemulsification cataract surgeries performed during 2018 (n = 1528), eyes with AL ≤22 mm and ≥25 mm were included and, after applying exclusion criteria, were validated (n = 114). Five IOL power formula predictions were compared to registered postsurgical refractions using IOL Master 500©. Two subgroups were created: eyes with AL ≤22 mm (n = 52) and AL ≥25 mm (n = 62). The formula performance in each subgroup was assessed by values of mean error, mean absolute error (MAE), median absolute error, standard deviation, and frequencies of eyes within lesser values of prediction error (PE). Results: The formulae presented different PE values in both subgroups. In AL ≤22 mm subgroup, the MAE was 0.622 (±0.120) for Barrett II, 0.684 (±0.153) for Haigis, 0.625 (±0.131) for Hoffer Q, 0.593 (±0.130) for Holladay I, and 0.593 (±0.119) for SRK/T, without statistical significance (P > 0.05). In AL ≥25 mm subgroup, the MAE was 0.409 (±0.110) for Barrett II, 0.739 (±0.159) for Haigis, 1.143 (±0.224) for Hoffer Q, 1.058 (±0.212) for Holladay I, and 0.928 (±0.190) for SRK/T, with statistical significance compared to Barrett II and Haigis (P < 0.001). In this subgroup, the application of Wang–Koch AL adjustment seemed an advantage in Hoffer Q and Holladay I, whereas a disadvantage in Haigis and SRK/T. Conclusions: Despite performing better than any other formulae, the 4th generation formulae performed worse than initially expected. Formula constants might explain this difference, and different IOL models can be used. However, these limitations are faced in day-to-day practice. Thus, these results hold their value as real-life refractive outcomes in eyes with extreme AL.","PeriodicalId":378703,"journal":{"name":"The Pan-American Journal of Ophthalmology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131321635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Study Design: A cross-sectional study of all individuals seen at the ophthalmology outpatient clinic during March 2016 to February 2017. Methods: All cases presenting to the ophthalmology outpatient clinic during March 2016 to February 2017 were reviewed (n = 895 patients, 1790 eyes). Visual acuity was measured using the Snellen chart. Results: The most common reasons for consultation were decreased visual acuity in 37.7% (326/865), foreign-body sensation 20.2% (175/865), glaucoma control 5.9% (51/865), screening or follow-up of diabetes mellitus (DM) 5.8% (50/865), and blunt trauma in 5% (43/865) of patients. A total of 252 (14.1%) eyes presented with a best-corrected visual acuity (BCVA) ≤20/200; 357 (19.9%) eyes had a BCVA 20/200; and 1181 (65.9%) had a BCVA ≥20/40. There were 40 (4.5%) patients that had a BCVA ≤20/200 bilaterally. The most common ophthalmic findings included cataract in 552 (30.8%) eyes, pterygium in 296 (16.5%) eyes, primary open angle glaucoma (POAG) in 187 (10.4%) eyes, age-related macular degeneration in 168 (9.4%) eyes, and 131 (7.3%) eyes with diabetic retinopathy (DR). Conclusions: The most common cause of ophthalmic consultation was decreased vision, of which 14% had a BCVA ≤20/200. The common findings included cataract, pterygia, POAG, age-related macular degeneration, and DR. Seventy-five percent of bilateral visual loss is avoidable.","PeriodicalId":378703,"journal":{"name":"The Pan-American Journal of Ophthalmology","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133042076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
