Nowadays, there seems to be way too many variations of Lasik eye surgery. It really is unbelievably easy to get lost in the complex world of Lasik and its alternatives. As a result, we are going to discuss a few of these procedures in an attempt to clear up any confusion you may have.
First, let's discuss the traditional Lasik procedure. With normal Lasik, a surgeon uses a blade to create a small flap in the patient's cornea. After the incision has been made, the surgeon then uses the laser to vaporize a portion of the stoma. This removal of the stoma is what causes the eye to reshape, which leads to better vision for the patient. In case you are wondering about the flap that was created, it will heal fairly quickly whereas the stoma does not heal.
Another variant of Lasik Dallas is Lasek, which sometimes is confused with Lasik since they sound so similar. Lasek is also a refractive eye surgery. During Lasek, the surgeon uses alcohol to remove layers of surface cells from the cornea (these cells are called epithelium cells). Since alcohol is used instead of a microkeratome blade, a side effect that is often experienced by patients is eye inflammation and eye irritation. Also, as a benefit, since alcohol is used instead of the blade, this surgery can be performed on people with thin corneas. Additionally, the recovery time is usually quicker with Lasek than with Photorefractive Keratectomy eye surgery.
Photorefractive Keratectomy (PRK) is another variant of Lasik that is still in use today. PRK was actually Lasik's predecessor. Nowadays, PRK is mostly used on patients who can not have Lasik due to their corneas being too thin or damaged. During the PRK surgery, a surgeon removes layers of epithelial cells using a mechanical blade (unlike in Lasek, where the surgeon uses alcohol). Also, in PRK, a surgeon uses a laser to gain access to the stoma without cutting a flap into the cornea.
Lastly, when compared with Lasik and Lasek, PRK offers a longer recovery time.
A recent improvement to Lasik is a variant called Epi-Lasik. This procedure is very similar to the Lasek procedure discussed above. The prime differentiator between these two procedures is that Epi-Lasik does not use alcohol to remove the layers of the epithelium cells. Instead this procedure uses a plastic blade to remove these surface cells from the cornea.
A side effect of this procedure that many patients complain of is eye irritation, although this will eventually go away. Additionally, your surgeon may require you to wear specialized contact lenses, which act as bandages, following the surgery.
The most precise variant of Lasik that we are going to talk about today is wavefront Lasik. With this method, the eye surgeon uses the computer and laser to truly create an individualized vision correct plan.
This is done by the laser bouncing light off of your eye and developing a three dimensional map of your eye. This map is able to identify any irregularities or aberrations in your eye with an amazing level of precision.
After the map is created, the surgeon then inputs some information into the computer and the computer and the machine do the rest.
The one glaring negative of this procedure is the cost. Since it uses new technology, requires much more of the eye surgeon's time, and the surgeon must pay a royalty fee every time he or she uses it, this procedure is much more expensive than the traditional Lasik procedure.
As we have shown, there are many variations of Lasik available today. With the knowledge gained today, we believe that you will be able to make a more informed decision. With that said, for the final authority on what is best for your eyes, we recommend you contact a Lasik surgeon for a consultation today.
