| Popis: | PURPOSE: To evaluate the accuracy and consistency of corneal flap thickness, horizontal diameter, and hinge size with the Moria M2 90-µm single use head. METHODS: Fifty-two myopic patients (104 eyes), mean age 32.6 years, underwent bilateral LASIK with a superior hinged flap using the Moria M2 microkeratome (90-µm single use head). Prospective evaluation included flap thickness (subtraction method), diameter, hinge size, interface particles, intraoperative complications, and visual recovery. RESULTS: The mean preoperative spherical equivalent refraction was -5.72±2.59 diopters (D) (range: -2.88 to -10.75 D) and -5.84±2.73 D (range: -3.13 to -9.38 D) for right and left eyes, respectively. The mean preoperative central corneal thickness was 548±24µm and 547±25 µm for right and left eyes, respectively. The mean preoperative steepest K was 44.12±1.28 D and 44.41±1.27 D for right and left eyes, respectively. Corneal diameter (white-to-white) was 12±0.4 mm and 11.9±0.4 mm for right and left eyes, respectively. The mean postoperative flap thickness was 109±18 µm (range: 67 to 152 µm) and 103±15 µm (range: 65 to 151 µm) for right and left eyes, respectively. The mean postoperative flap diameter was 9.4±0.3 mm (expected mean according to the nomogram given by the company was 9.5 mm). The mean postoperative hinge chord was 4.4±0.4 mm (expected mean 4.2 mm). No interface particles were detected on slit-lamp examination. CONCLUSIONS: The Moria M2 90-µm single use head is safe with reasonable predictability for LASIK flap creation. [J Refract Surg. 2007;23:45-49.] |
