ABSTRACT Objective: To develop and validate a prototype of magnifying glasses to improve precision and safety in the extraction of corneal foreign bodies. Methods: The prototype was made on a 3D printer using ABS material, containing a 30x magnifying glass and LED lighting. Validation was carried out by 22 specialist ophthalmologists using the Delphi method, who evaluated the device’s functionality, usability, aesthetics, safety, and durability. Statistical analysis included the Content Validity Index (CVI) and McDonald’s Omega coefficient. Results: The experts […]
