Q Value Customized Versus Wavefront Optimized Ablation in Femtosecond Laser-Assisted LASIK

NCT04738903 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

No results posted yet for this study

Summary

Corneal asphericity is expressed numerically as the "Q-value". A minus value means that corneal curvature flattens towards the periphery and the cornea is prolate in shape, but when the curvature steepens towards the periphery, the cornea is oblate in shape and has a positive Q-value.

The current study evaluates the effect of LASIK eye surgery on corneal asphericity by comparing 2 software treatment platforms; the Q value customized ablation versus the conventional Wave-front optimized ablation in a fellow eye study pattern.

Conditions

  • Patients With Myopic Spherical Equivalent up to -12 Diopters

Interventions

PROCEDURE

Femtosecond laser assisted LASIK eye surgery

FS-LASIK eye surgery includes corneal flap creation with femtosecond laser using the Femtosecond laser WaveLight FS200 followed by excimer laser vision correction of the patient's refractive error using excimer laser WaveLight EX500.
