Toric Contact Lens Performance Study
- Conditions
- Astigmatism
- Registration Number
- NCT03546647
- Lead Sponsor
- University of Houston
- Brief Summary
This study seeks to quantify digital visual performance and subjective visual acceptance of toric contact lenses as compared to spherical lenses in low to moderate astigmatic patients.
- Detailed Description
This is a prospective, single site, randomized, masked, crossover study. This study will evaluate the ability of toric contact lenses to decrease signs and symptoms of asthenopia and improve digital reading performance. Symptoms and objective near vision outcomes will be measured at baseline and after 1 week of wear with each correction.

Name Time Method Near Visual LogMAR Acuity 10 +/- 2 days High contrast LogMAR visual acuity was assessed at 40 cm using the M\&S Clinical Trial Suite system (Niles, Illinois, USA). The system was calibrated according to the manufacturer's directions every day, prior to use. Testing was performed binocularly. The test started at 20/200 and continued until three letters were missed on a line.
