The Effect of a Scleral Lens on the Anterior Chamber Depth and Minimum Rim Width

NCT03926975 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 26

No results posted yet for this study

Summary

The purpose of this study is to evaluate the use of two instruments to measure changes in two ocular structures: 1) the anterior chamber depth (ACD) - measured using low coherence optical biometry, and 2) minimum rim width of the optic nerve head (MRW) - measured using optical coherence tomography. Changes in these ocular structures indicate fluctuations in intraocular pressure (IOP) and will be measured during scleral contact lens (SGP) wear to determine if SGP wear influences IOP. We hypothesize that a scleral lens increases the intraocular pressure (IOP) during active wear and that the ACD and MRW will also change.
