Access and usage of technology was compared between academic and community practices, United States and non-United States, and high-volume (≥60 SLs) and low-volume fitters.</p><p><strong>Results: </strong>423 practitioners who fit SL for keratoconus participated. Image- and impression-based technologies were more frequently available in academic practices compared with community practices and high-volume compared with low-volume practitioners ( P <0.005). Practitioners with image-based technology used it for a median [interquartile range] 5 [25]% of SL fittings; those with impression-based technology used it for 8 [9]% of fittings, and those with both types of technology used image-based devices for 12 [23]% of fittings and impression-based for 5 [8]% of fittings.</p><p><strong>Conclusions: </strong>In this study, most participants report using diagnostic lenses to fit SLs for patients with keratoconus.</p>","PeriodicalId":50457,"journal":{"name":"Eye & Contact Lens-Science and Clinical Practice","volume":" ","pages":"292-296"},"PeriodicalIF":2.0,"publicationDate":"2024-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11296498/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141793974","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}
