Very high-frequency digital ultrasound measurement of the LASIK flap thickness profile using the IntraLase femtosecond laser and M2 and Carriazo-Pendular microkeratomes.

摘要: PURPOSE To evaluate the corneal aberrometric outcomes and flap thickness profile after LASIK using three different devices for lamellar keratotomy: Moria M2 microkeratome, SCHWIND Carriazo-Pendular IntraLase femtosecond laser. METHODS Sixty-six myopic eyes of 33 patients who underwent with ESIRIS excimer laser were enrolled in this study. Lamellar keratotomy was performed that assigned randomly to each patient: The intended depth 110 microm all cases. Flap profile, aberrations, contrast sensitivity, refractive evaluated. RESULTS Mean central 117.50 +/- 7.80, 118.08 8.34, 115.95 6.22 M2, Carriazo-Pendular, systems, respectively. No significant differences found among groups. Nasal thicknesses significantly larger flaps compared (P < .05) = .046 only at 3-mm position). Temporal flaps, although between reached statistical significance. Larger superior inferior also observed no statistically found. Regarding aberrometry, coma-like .138) spherical-like root-mean-square .300). CONCLUSIONS systems create predictable during LASIK. Additionally, a planar profile.
