[Predictability of the corneal flap creation with the femtosecond laser in LASIK].

Objective: To observe the predictability of corneal flap creation with the FEMTO LDV femtosecond laser and analyze preliminarily the factors correlating to the thickness and diameter of the flap .

Methods: It was a study of serial cases. 260 eyes of 130 consecutive patients were treated with the FEMTO LDV.

Contrast sensitivity and higher-order aberrations in patients with astigmatism.

Background: Astigmatism is one of the most significant obstacles for achieving satisfactory visual function. This study was to evaluate the influence of astigmatism on contrast sensitivity (CS) and higher-order aberrations.

Methods: CS, accommodation response and wavefront aberration were measured in 113 patients with astigmatism, aged 18 - 36 years.
