Laser In-situ Keratomileusis With Crosslinking Compared to Conventional LASIK in Patients With High Myopia

By randomized selection, one eye was treated with the LASIK Xtra procedure that consists of fs-LASIK treatment combined with intraoperative accelerated continuous UV-riboflavin crosslinking. After laser ablation, the corneal bed under the flap was coated with riboflavin, rinsed with saline solution, and after 90 seconds the corneal flap was repositioned. The eye was irradiated at 30 mW/cm2 for 90 seconds with continuous UVA.
