Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The overall objective is to develop the hardware systems and software algorithms necessary to make accurate measurements of the whole eye with optical coherence tomography (OCT). The research procedure that each subject will undergo is imaging with the OCT system. Three populations will be included: 1. Normals to ensure the imaging range of the system, 2. Patients with previous LASIK who will be undergoing cataract surgery, and 3. Patients with a history of cataract surgery or high myopia. The third group will also undergo MRI imaging for comparison. There are no known risks to the subject from imaging with optical coherence tomography beyond what is normal for standard ocular photographic procedures. Light exposure is below ANSI limits. In groups 2 and 3, clinical parameters drawn from the OCT images will be compared to standard of care imaging.
