A pilot study involving a 3-month implantation in a rabbit was conducted, including histological analysis.</p><p><strong>Results: </strong>Flexible acrylic copolymer sheets of high clarity were produced by free radical polymerization. Their mechanical properties and refractive indices could be altered with different material formulations. They demonstrated no <i>in vitro</i> toxicity in human corneal cells <i>via</i> MTT assay. 3D printed silver molds allowed for the production of keratoprostheses of complex shapes made from these materials. Surgical implantation resulted in clear implant at 3 months.</p><p><strong>Conclusions: </strong>Molding of flexible acrylic allows for production of one-piece keratoprostheses of a complex shape and opens new possibilities for the treatment of corneal blindness.</p>","PeriodicalId":10782,"journal":{"name":"Current Eye Research","volume":" ","pages":"1-7"},"PeriodicalIF":1.7,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143771727","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}
