The FemTec™ Laser Microkeratome is indicated for use in the creation of a corneal flap in patients undergoing LASIK surgery or other treatment requiring initial lamellar resection of the cornea.

The FemTec Laser Microkeratome is intended for use in the creation of a corneal flap by producing short bursts of laser pulses, with each laser pulse having a duration on the order of 500 to 1000 femtoseconds ("fs", 10-15 seconds). Microscopic gas bubbles, which form as a result of the laser induced optical breakdown (LIOB), arc created adjacent to each other at a pre-determined depth in the cornea. It is this continuous layer of gas bubbles that create the lamellar corneal dissection plane just like a mechanical microkeratome blade. The FemTec Laser Microkeratome creates a flap under very low vacuum (250 mbar), and delivers the laser energy directly to the stromal layer of the cornea through a disposable PMMA contact lens, referred to as the Patient Interface (PI).
