The operation was performed with Visumax femtosecond laser platform (Carl Zeiss Meditec AG, Jena, Germany). The spot distance was 3 µm for lamellar cuts and 2 µm for side cuts. The spot energy was set to 140 nJ. The minimum lenticule side cut thickness was set to 15 µm. The lenticule side cut angle was 120, and the optical zone was 6.5 mm.
When the lenticule and side cut had been created, the surgeon positioned the eye under the operating microscope of the laser platform. Under the operating microscope, a blunt spatula was inserted into the anterior lamellar photodisruption plane to perform dissection of any remaining attachments. The same maneuver was performed in the posterior lamellar photodisruption plane. After the lenticule was completely dissected from the overlying and underlying stroma, it was extracted through the side cut with forceps.
Postoperatively, all eyes received dexamethasone eyedrops 4 times daily for 2 weeks and moxifloxacin 0.5% drops 4 times daily for 5 days. Artificial tears were prescribed to be used for at least 1 month.
