A good LASIK … WebInterestingly, the aforementioned study correlated the lower efficacy index of eyes treated with microkeratome to the deviation in achieved versus intended flap thickness. 15 Several studies have shown that flaps produced using Femto-LASIK are more predictable, thinner, and have a favorable planar shape. 19–22 However, it is unclear whether ...
WebIn LASIK-treated corneas, total corneal thickness was further subdivided into flap and residual stromal bed thickness by the LASIK interface that was easily identified by the presence of brightly reflecting particles. 18 Only scans from the photoablation center, defined as the region of minimal stromal thickness, were used for subsequent analyses. WebManagement:Depending on the amount of residual stroma and the location of the flap hinge, the surgeon should decide to either terminate the procedure or continue with …
