The two-part LASIK procedure is completed using a microkeratome blade and a highly advanced laser that work together to reshape the cornea to improve vision. In addition to this traditional method, Cornea Associates of Texas performs iLASIK surgery which utilizes two lasers and eliminates the use of the microkeratome blade.
When we do LASIK surgery, there are two parts of the procedure. The first part involves preparing the flap of the cornea and the second part involves using a laser to reshape the cornea and there are two different ways we can actually prepare the flap. The traditional way has been to use a machine called a microkeratome, which is a surgical instrument that curves the thin flap of the cornea that we can fold over to do the second part of the procedure, the laser treatment. There is another approach in preparing the flap and that involves using a separate laser called the IntraLase and this laser will actually prepare the flap with the laser rather than cutting it with a surgical instrument. The benefit of the IntraLase involves the safety that it brings to the procedure. The microkeratome is still a very good machine, but like any surgical instrument there are some concerns about how the flap could be cut and if the flap is cut in an irregular fashion then we may not be able to perform the actual laser treatment. With the IntraLase, because it is a laser driven computer controlled machine, it is very precise and very safe and we very rarely would ever see problems with an irregular flap with the IntraLase, so it brings safety to the procedure and is a preferred way for doing LASIK surgery.
