Should I Choose Femtosecond Intra-LASIK & Traditional LASIK?

In all forms of LASIK procedures, a cornea flap in the eye must be cut opened in order for the laser to shape the eye lenses. The IntraLase® laser was approved by the FDA in 2001, it is the first and only laser technology approved for use in the first step of the LASIK procedure, creating the corneal flap. And the only difference between traditional LASIK and IntraLASIK is that the flap is created using a femtosecond laser microkeratome rather than with a mechanical microkeratome or steel blade.

Should I Choose Femtosecond Intra-LASIK & Traditional LASIK?

Better Vision Results

The main advantages of Intra-LASIK with femtosecond laser is reduce the harm for corneal than creating the corneal flap with microkeratome. The metal blade of microkeratome can create uneven edges on the flap even cause to scars, which can lead to vision defects like astigmatism. The issues is less to happen with the femtosecond laser of Intra-LASIK. Intra-LASIK has been shown clinically to deliver better visual outcomes in both standard and microkeratome LASIK procedures with more patients achieving visual acuity of 20/20, 20/15 and even 20/12.5.

Thin Corneas May Be Good Candidates For Intra-LASIK

The Intra-LASIK with femtosecond laser also make it possible for individuals with thin corneas to undergo the procedure. The thin corneas about 500 to 600 microns are considered to be ineligible for the microkeratome LASIK because the microkeratomes will cut about 100 to 200 microns. The Intra-LASIK with femtosecond laser only need to cut a flap as thin as 100 microns. People who are ineligible for traditional LASIK because of thin corneas may be good candidates for Intra-LASIK.

Severe Dry Eye Symptoms Has Been Greatly Improved

The clinical studies show that use of the mechanical bladed microkeratome of LASIK is responsible for a significant amount of dry eye symptoms. However, the Intralase flaps markedly reduce nerve injury and allow for rapid nerve regeneration compared to old microkeratome methodology. The severe dry eye symptoms has been greatly improved with the Intralase of LASIK.

Cost Of IntraLase System Is The Biggest Factor In Why Surgeons Do Not Use

The greatest disadvantage of the microkeratome over the Intra-LASIK with femtosecond laser is the cost.

The cost of a IntraLase® Femtosecond system is about $500,000 and there is an annual maintenance fee of approximately $70,000, and a cost of disposable suction ring about $200 per eye. A microkeratome can be purchased for $35,000 or less, there are no annual maintenance fees and the cost of a blade is around $50 for both eyes.

The cost of IntraLase® system is probably the biggest factor in why many surgeons do not use the Intra-LASIK with femtosecond laser technology. Another disadvantage that almost no consideration is that the procedure with femtosecond laser takes a little more time than traditional LASIK surgery.
