Recent developments in LASIK technology mean that those who suffer from higher-order vision aberrations, such as halos and astigmatismcan also enjoy significantly improved vision in one minute procedure. To perform a LASIK procedure, your doctor will create a very thin flap in the surface of your eye, either manually or using surgical lasers. After carefully lifting up this flap, the surgeon can access the cornea, which he or she will reshape with a computer-driven laser.
How the eye is tracked and the laser is aimed. This makes for a dizzying variety of possible procedures falling under the Laser Eye Surgery umbrella. While some discussions on laser eye surgery focus on comparing Lasik, Lasek, PRK, etc, even this level of detail covers only a subset of the important differentiators, and decision points, that make up just the first grouping above.
In order to truly understand the procedure, prospective patients need to look at each of these areas in detail. In this article, I will focus on just the first major question: For more information about the subsequent important! Correction Site and Access: Lasik vs PRK The most critical decision in choosing a laser eye surgery procedure is selecting where the correction is made and how that correction site is accessed.
The four primary types of laser eye surgery, PRK, Lasik, Lasek, and Epi-Lasik fall within two main categories of where the correction is made: Each procedure and their sub-types are refinements on how that correction site is accessed.
Lasik mid-cornea procedures are always more invasive, significantly compromising the biomechanical integrity of the eye. While each of the differences between the various procedures warrants careful consideration, this factor alone, where the correction is made, has by far the greatest impact on overall short-term and long-term risk of the surgery.
These mid-cornea procedures are relatively new compared to the much older cornea-surface procedures.
As illustrated above, the flap-based correction method involves cutting a significant way through the structure of the cornea, before any corrective shaping is performed.
As a result of this, Lasik mid-cornea procedures are always more invasive, significantly compromising the biomechanical integrity of the eye. With PRK pictured belowthe skin layer is loosened by an alcohol bath, removed completely via a blade, and then allowed to grow back over the cornea after surgery.
With Lasek and Epi-Lasik, the skin layer is loosened by an alcohol bath all Lasek and some Epi-Lasika skin-only flap is created via a blade, and then re-seated overtop the cornea after surgery. As illustrated above, the cornea-surface correction method involves lifting off the epithelium, the skin layer, then correcting the surface of the cornea.
As a result, the cornea-surface procedures are the least invasive, retaining the highest degree of biomechanical integrity of the eye. Each of the surface-ablation methods are quite similar, with the only differences being how the skin is removed and whether or not it is reseated after surgery.
Check out the Pros and Cons section below for a more detailed breakdown of each. This graphic illustrates diopter cornea-surface corrections. The ugly truth about Lasik is that the cornea flap never actually heals.
The cut is permanent. The cornea is forever compromised. Use your instincts when assessing the wisdom of severing a significant portion of the cornea. Ask yourself what purpose the cornea serves See: Bear those thoughts in mind as you read the following areas of concern with the Lasik procedure.
