About This Trial
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…
