Eyes are the most vital and sensitive organs as far as human life is concerned, and when it comes to the need to undergo an eye surgery, people get nervous. This is more so if you are unaware of the nature of the surgery and procedures involved.
LASIK is one such surgical procedure to enhance the focusing ability of the eye by adjusting the contour of cornea. This FDA-approved procedure is quite popular now as a corrective surgery to improve the quality of life of people with impaired vision.
Here is a quick look at the procedure in details.
The procedure of LASIK surgery
LASIK surgery is conducted in two steps. Pre-surgery, the patient has to be qualified for it by undergoing a detailed eye exam conducted by experts.
- At the first step of LASIK procedure, an expert surgeon gain access to the cornea through a very think tissue flap.
- Once a clear access is gained, the tissue is folded back and then the surgeon performs vision correction process with laser assistance on the inner corneal layer.
No blade LASIK
In conventional LASIK procedure, the tissue flap is created with the use of a handheld device with a metal blade on it. This is used to create a small cut in the cornea to allow smooth passage. However, with the use of a blade, surgeon may not be able to allow full customization of the flap, which is vital in terms of ensuring the perfection of vision correction. Here comes the importance of a more perfect no-blade LASIK procedure.
No-blade LASIK is also know as all-laser LASIK, which is a highly advanced variant of standard LASIK procedure by taking advantage of improved procedural tools. As you know by now, LASIK eye surgery is basically a two-step procedure and both parts of it are crucial.
In no-blade LASIK technology, instead of the handheld device with blade, A laser devise named ‘IntraLase laser’ is used to the first step of LASIK surgery. The IntraLase process uses a precise laser to gain better access to the cornea.
This gives the surgeon more control over customization of the flap and enables a much precise and safer corneal correction. This method takes away all the variables and risks out of the step of flap creation by replacing it with a more customized process to ensure optimal results.
Safer and precise LASIK
The precision of no-blade IntraLase LASIK procedure is also clinically proven in the studies conducted for FDA clearance, in which the accuracy of flap thickness with laser access is demonstrated at about +/- 10 microns. Precise flap thickness is a very critical aspect of LASIK to ensure its successful outcome, and IntraLase assisted flaps are found to have a consistent edge-to-edge thickness when compared to blade cut flaps.
Two types of lasers are used in all laser LASIK. One is the high-accuracy femtosecond laser that eradicates any need for manual tools at the first stage of LASIK surgery to create flap. During the second step of corneal correction, an excimer laser is used.
The cost of no-blade LASIK is obviously a bit higher than conventional surgery, but most of the patients now prefer to go ahead with it as this can ensure added level of safety and also more precise results in vision correction.
