Visual Outcomes and Contrast Sensitivity After Myopic LASIK

Phase 4

Completed

• Conditions: Myopia
• Interventions: Device: bilateral myopic LASIK

• Registration Number: NCT01746589
• Lead Sponsor: Daniel S. Durrie, MD

Brief Summary

Evaluate visual outcomes and contrast sensitivity for subjects undergoing bilateral myopic LASIK procedure using the 200 kHz WaveLight® FS200 Femtosecond Laser and the WaveLight® Allegretto Wave® Eye-Q Laser. The use of advanced technology may decrease the loss of contrast sensitivity and improvement of postoperative visual acuity results.
