A Prospective Study of Femtosecond Laser Intracorneal Lensectomi

A Prospective Study of Femtosecond Laser Intracorneal Lensectomi in Treatment of Moderate to High Myopia

The purpose of this study is to compare visual acuity, safety, predictability, corneal biomechanics, dry eyes, and nerve-morphology after all femtosecond laser refractive lenticule extraction. Approximately 30 to 40 patients with moderate to high myopia will randomly (after ocular dominance) receive ReLEx flex in one eye, and ReLEx smile in the other.

Inclusion Criteria:

• 25 to 45 years,
• moderate to high myopia with astigmatism =< 2 D,
• otherwise eye healthy,
• CDVA of 0.8 or better (Snellen).

Exclusion Criteria:

• systemic or ocular disease or previous eye surgery,
• thin cornea,
• a difference of more than 2 D myopia in the eyes of each subject.
