Specific Aims : Develop a complete pre-production MRCT system. To accomplish this goal, the specific aims are to develop the following: 1) optimized reflection target with LED back lighting; 2) electro-optics assembly; 3) optical head mechanical frame; 4) optical head enclosure; 5) system software; 6) mechanical interface to off-the-shelf manipulator; 7) calibration fixture and software. We will also evaluate performance of the system with test objects. Health Relatedness: Provide more accurate anterior surface measurements needed for research and vision intervention techniques that correct higher-order aberrations. Methods: The project incorporates a novel reflection target design, reconstruction algorithm, and a high- resolution digital camera. We refer to this new system as the muti-resolution corneal topographer (MRCT) because the reflection target employs color sinusoidal profiles that provide three simultaneous multiple- resolution ring images. Technological Innovation: The MRCT system represents a new way surface that will be more robust and accurate than other commedcally Our approach is a technological innovation over traditional reflection color sinusoidal ring target to acquire multiple-resolution ring images PERFORMANCE SITE(S) (organization, city, state) Sarver and Associates, Inc. 1020 Wild Elm Street Celebration, FL 34747 of measuring the anterior corneal available corneal topography systems. target methods in that it incorporates a (9, 17, and 33 rings) in a single exam.
