Lasik Eye Surgery
If you or someone you care about has been considering corrective eye surgery, you've
probably heard the term lasik eye surgery. You may have wondered if it's just a fancy
term for laser eye surgery or if there's more to it than that. The answer is yes and no.
Lasik eye surgery is a specific eye procedure whose purpose is to reshape the cornea.
The difference between "lasik eye surgery" and "Custom lasik surgery"
The major difference between traditional lasik eye surgery and custom lasik surgery is
the way that measurements are taken before the procedure. In traditional lasik corrective
surgery, the laser is calibrated to measurements based on your eyeglass or contact lens
prescription. In custom lasik, the ophthalmologist uses a device called a wave analyzer
to measure the way light passes through the eye. By measuring the way light hits your
retina, he has a precise map of YOUR cornea. This gives him custom measurements to program
the laser when shaping your cornea. It's like the difference between buying an off-the-rack
suit and having one custom-fit just for your body.
How Lasik Vision Correction Works
The cornea is a layer of clear tissue over the front of your eye that allows the light to
pass through, and helps to focus it properly on the retina. Many vision problems are caused
by malformations or small aberrations in the shape of the cornea that distort the passage of
light. Lasik vision correction works by using cool lasers to literally reshape the cornea,
and then correct the way that light passes through it to focus on the retina.
Other forms of lasik eye surgery
Other variations of lasik surgery like Lasik Plus Interlace and Epi-Lasik do away with the blade entirely, and use lasers to make the corneal incision. In addition, there are other alternatives to lasik surgery like CK, or conductive keratoplasty, which uses radio waves to treat farsightedness and PRK, or photorefractive keratectomy, which uses lasers to reshape the cornea.
What are the potential lasik complications and risks?
Lasik complications and risks associated with lasik surgery include vision aberrations like halos and starbursts or reduced contrast vision. Complications from lasik surgery are rare, but when they do occur, they're often caused by problems with the 'flap that cause vision distortion. Other risks include a worsening of the vision after surgery, dry eyes, and in very rare cases, permanent vision loss. These complications are rare, but should be considered if you're considering lasik surgery.
What is the cost of lasik eye surgery?
The cost of lasik surgery is another consideration in your decision. It will depend on the amount of correction required to your vision and the type of lasik eye surgery procedure you selected. In the last quarter of 2004, the average cost of lasik eye surgery procedure was US$1800. You can find prices as low as US$425 per eye, or as high as US$2500 per eye. In addition, keep in mind that most health insurance doesn't cover the cost of lasik surgery when making your decision.
How to choose a lasik eye surgeon?
Choosing a good lasik eye surgeon shouldn't be based on cost alone. While lasik eye
surgery may seem uncomplicated, it's still surgery, and you will want the best doctor
that you can find. To help you find a good lasik eye surgeon, follow these
