About this trial
The purpose of this study is to see if OCT technology can optimize scleral contact lens fittings. Subjects with keratoconus, post-penetrating keratoplasty (PK), post-LASIK ectasia, post-radial keratotomy (RK), or a variety of anterior surface disorders requiring scleral lens fittings will be considered for enrollment. For each study eye, a clinically-selected scleral lens fit will be compared against an OCT-selected lens fit. The quality of each lens fit will be determined by flourescein exam at the slit lamp. Apical clearance, limbal clearance, conjunctival compression, and lens edge lift will be assessed. A lens that satisfies all four criteria will be considered satisfactory.
