Official title
Optical Coherence Tomography-Aided Differential Diagnosis and Treatment of Irregular Corneas
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This main goal of this study is to improve the detection, classification, monitoring, and treatment of irregular corneas due to keratoconus, warpage, dry eye, scar, stromal dystrophies, and other corneal conditions. The primary goal will be achieved by using optical coherence tomography (OCT) to: 1. Develop an OCT-based system to classify and evaluate corneal-shape irregularities. 2. Develop OCT metrics for more sensitive detection of keratoconus progression. 3. Develop OCT-and-topography guided phototherapeutic keratectomy (PTK) for irregular corneas.
