What is 'laser eye surgery'? What is LASIK surgery? How can I find a laser eye surgeon? What is the difference between LASEK and LASIK surgery? These are just a small part of the many questions people ask of laser eye surgery.
Here, we propose what we believe is a comprehensive and easy to understand guidance, laser vision correction.
There are two main methods used in laser eye surgery:
1. Corneal laser eye surgery
2. Laser refractive surgery
The main difference is the matrix of two surgical methods, the middle layer of the cornea, exposure prior to laser vaporization. In the PRK surgery, at the top of the cornea, called the epithelium, stroma scraped away to expose the following. In the cornea, a reduction in the matrix layer and the flap folded back.
This guide provides an overview of laser surgery, including possible complications of treatment.
Excimer laser eye surgery
Excimer laser advocates laser corneal epithelial Keratomilieusis, very similar, short-sighted apart from one thing: the outer layer of corneal epithelium or retained. This is indeed a relatively new variation of the refractive laser energy directly applied to the outer surface of the shape of the eye to correct people's vision. To understand the excimer laser works, you need to know the difference, from the LASIK and PRK.
In LASIK surgery, a thin flap is cut in the eye's surface, and then it is lifted. In order to reshape the eye, the shape of the cornea under the laser energy. Flap is put back into place, act as a natural bandage for an operation. This will also speed up the healing process.
In the myopia of the program, rather than cutting a thin flap in the eye's surface, laser energy directly applied to the surface of the eye. Ultra-thin outer layer called the epithelium. This layer is completely removed with laser energy in the PRK surgical procedure. Epidermal growth back in time.
In the excimer laser process, save the epithelial cell layer. This application is made before the lifting of laser energy. When the shaping is completed, the surface of epithelial cells back into the eye.
The main difference between LASIK and excimer laser method is to use a microkeratome corneal cutting tool or a special laser, and in the excimer laser method, the tool called a trephine use.
Who is suitable candidate excimer laser eye surgery?
Excimer laser is an ideal program for people who are too thin corneas or too steep. Excimer laser to reduce the chance of complications with the corneal flap method. If the flap thickness is not satisfactory, the excimer laser corneal methods may be right for you. Excimer laser-produced thin flap than in LASIK surgery methods.
Remember, those who after excimer laser treatment than those who slow after LASIK surgery. In addition, people who through the excimer laser procedures tend to have more complaints. Given these results, doctors generally prefer to perform excimer laser photorefractive keratectomy.
What will happen during the excimer laser procedure?
In an excimer laser procedure, local anesthesia will be used. Epithelium will reduce the use of a fine blade called a trephine. Eye surgeon will fill half a minute with diluted alcohol solution will allow loose epithelium. Flap will be folded out of the way so that there is an operational space of corneal tissue below it. A excimer laser will be used for similar LASIK and PRK, and then flap is put back into a better healing.
What will happen after excimer laser procedure?
Excimer laser, the recovery is slow compared with recovery from the cornea. According to the doctor who performed the excimer laser, flap will heal within a day, but the eye bandages usually takes about 4 days to protect the eyes from infection and foreign stimulation. From the excimer laser to restore the process is relatively slow, but it is not easy to infections and complications, especially in dry eye. You may feel some discomfort in your eyes the first 48 hours with the excimer laser. This will take longer for your vision back to normal, if the excimer laser on the implementation of the program compared to your LASIK surgery. This may require a week or so of your vision fully restored. In the excimer laser process is generally more painful than LASIK surgery.
