| Popis: | Purpose: To analyze the accuracy and consistency of corneal flap thickness created in myopic LASIK using the Moria One Use-Plus microkeratome compared with the Moria M2 Single Use 90- μ m microkeratome. Methods: Bilateral LASIK was performed in 68 myopic patients. Flaps were created using the One Use-Plus microkeratome in 82 eyes (41 patients) and the M2 90- μ m microkeratome in 54 eyes (27 patients). Flap complications and visual outcomes were evaluated. Horizontal “High Res. Corneal” scan pattern of anterior segment optical coherence tomography (AS-OCT) was applied to measure flap thickness at five locations (0, ±2, and ±3.5 mm from the corneal vertex) on the first postoperative day. Results: No significant differences were noted in flap complications and visual outcomes between groups. The central flap thickness was dramatically thinner in the One Use-Plus group (114.7±10.1 μ m and 109.4±11.0 μ m for right and left eyes, respectively) than in the M2 group (155.6±14.8 μ m and 151.6±12.5 μ m for right and left eyes, respectively) ( P P Conclusions: The One Use-Plus and M2 microkeratomes have similar safety and efficacy. The flap created by the One Use-Plus was much thinner than the flap created with the M2; however, the One Use-Plus can not realize a fully planar-shaped flap. |
