Intralase

InstraLASIK is a form of LASIK that creates a corneal flap using a femtosecond laser microkeratome instead of the mechanical microkeratome, which uses steel blades. For the most part, the only difference between traditional LASIK and intraLASIK is, indeed, the way in which the LASIK flap is created. Once the corneal flap is removed, an excimer laser is used on the inner cornea to correct vision.
The creation of the flap is an important part of the laser eye surgery procedure. It’s true that flap predictability is better with a laser flap than with bladeless LASIK. Moreover, there is a reduced possibility of flap complications, such as partial flaps, flap dislocation, free flaps etc. However, an expert surgeon wielding a contemporary microkeratome can very well match the finesse of bladeless LASIK. Although the chances are rare, there is an issue of transient light sensitivity as well – a unique risk associated with blade less LASIK. Moreover, the bladeless LASIK procedure costs an extra $300 per eye, when compared with traditional LASIK.
