Purpose:
To describe a method of LASIK enhancement in which a femtosecond laser-assisted new flap is performed over the original LASIK flap
Setting:
VISSUM Corporación Oftalmologica Santa Hortensia, Madrid, Spain
Methods:
We performed a femtosecond laser-assisted new flap over a primary LASIK flap for the enhancement of post-LASIK late regression. The new flap, we called it as " mini-flap" must be smaller in diameter and thinner than the original LASIK flap: usually the preferred diameter is 7 mm, and the attempted flap depth is 100 microns. The purpose of the " mini-flap" is to be smaller and thinner than the original LASIK flap, so the ablation can be performed over the deepest lamellae of the original flap, and not over the original stromal bed, thus decreasing the risk of excessive stromal thinning and postoperative ectasia
Results:
We treated ten eyes with this technique. All eyes were within 0.5 diopters of emmetropia at the 3-month postoperative visit. No intraoperative or postoperative complications were found in any case during the follow-up
Conclusions:
Performing a femtosecond laser-assisted new flap over a primary LASIK flap is a safe and effective procedure for the enhancement of post-LASIK late regression. This method reduces the risk of epithelial ingrowth associated with manual flap-lift retreatments, and the risk of flap-related intraoperative complications associated with recutting a new flap with a mechanical microkeratome FINANCIAL DISCLOSURE?: No
