- To begin with, your eyes will be numbed using an eye drop anesthesia.
- Then, we will place an eyelid holder between your eyelids so you don’t have to worry about blinking.
- Next, we will make a thin protective flap in the cornea. At our center, you have the option of utilizing a razor-sharp microkeratome blade, or our all-laser IntraLASIK technology. You may feel a little pressure, but you won’t feel any pain.
- After your protective flap is folded back, a laser beam will gently reshape your cornea. The actual procedure lasts only a few minutes per eye.
- The protective flap will be folded back into place, where it will bond with your eye without the need for stitches. You will likely experience some sensitivity to light and blurred vision immediately following the procedure, but most people can return to work within 24 hours.
What LASIK Delivers
LASIK utilizes the Excimer laser to reshape the protective front window of the eye, called the cornea.
- In nearsighted patients – those who can’t see far away clearly – the cornea is flattened by removing a thin layer of tissue from the center of the cornea.
- In farsighted patients – those who can’t see close up clearly – the center is made steeper by removing tissue from the outer portion of the cornea.
- For astigmatism, the oval-shaped cornea is made more round by removing more tissue in one direction than the other to make the shape more spherical
The Excimer LASER
The actual laser used in LASIK, LASEK, PRK and laser vision correction is known as the excimer laser. This excimer laser is used to permanently change the shape of the cornea, or the outer layer of the eye. The EXCIMER laser, which is a specific type of "cool" laser, generates its power from light in the ultraviolet range. It cannot be visualized by the human eye. Because the laser does not generate any heat, there is no tissue damage as the result of the laser light. As the treatment with the laser proceeds, microscopic layers of tissue, approximately 1/10th the width of a human hair are removed. The laser is programmed to remove precisely the amount of tissue needed to achieve the desired result.
LASIK eye surgery is a surgical procedure performed on the cornea part of the eye. It is very necessary that LASIK candidates are well educated on the potential benefits and risks of the LASIK procedure. As with any type of surgery, risks are involved. After your pre-operative evaluation you will have a good idea about the risks and what they mean to your specific visual situation. It is important to discuss any concerns with your surgeon and weigh the risks and potential benefits. Each patient’s vision is different and different treatment options are available in order to give the best possible results. The only way to determine if LASIK is right for you is to come in and discuss your options with our LASIK coordinator. Vance Thompson Vision is committed to safety and patient care and as a result invests in the latest technology and the most advanced procedures. If you are not a candidate for LASIK eye surgery there may be other options. Please feel free to discuss your specific visual situation with our staff and we will determine the best possible solution.
The LASIK procedure is the right answer for most patients who are considering refractive surgery to improve their vision. However, in patients with higher degrees of nearsightedness or farsightedness, the cornea may be too thin to allow full refractive correction.
In these cases, surgical implants may be the best alternative. These special devices are placed in the eyes to improve their focusing ability.
