LASIK SURGERY

Hi  friends today i am talking about LASIK EYE SURGERY.you can see world now with your eyes without any contact lenses or specs, I have a personal experience of it and i am enjoying,

LASIK, which stands for laser in-situ keratomileusis, is a popular surgery used to correct vision in people who are nearsighted, farsighted, or have astigmatism.

All laser vision correction surgeries work by reshaping the cornea, the clear front part of the eye, so that light traveling through it is properly focused onto the retina located in the back of the eye. LASIK is one of a number of different surgical techniques used to reshape the cornea in most cases, laser eye surgery is pain-free and completed within 15 minutes for both eyes. The results — improved vision without eyeglasses or contact lenses — can usually be seen in as little as 24 hours.

Laser eye surgery requires only topical anesthetic drops, and no bandages or stitches are required.
It works! It corrects vision. Around 96% of patients will have their desired vision after LASIK. An enhancement can further increase this number.

• LASIK is associated with very little pain due to the numbing drops that are used.
• Vision is corrected nearly immediately or by the day after LASIK.
• No bandages or stitches are required after LASIK.
• Adjustments can be made years after LASIK to further correct vision if vision changes while you age.
• After having LASIK, most patients have a dramatic reduction in eyeglass or contact lens dependence and many patients no longer need them at all

Before LASIK Surgery
Your eye doctor will perform a thorough eye exam to ensure your eyes are healthy enough for the procedure. He or she will evaluate: the shape and thickness of your cornea; pupil size; refractive errors (myopia, hyperopia and astigmatism); as well as any other eye conditions.

BEST CANDIDATES
mild/moderate myopia, hyperopia and/or astigmatism, adequate corneal thickness

• The moistness of your eyes will also be evaluated, and a precautionary treatment may be recommended to reduce your risk of developing dry eyes after LASIK.
• Usually, an automated instrument called a corneal topographer is used to measure the curvature of the front surface of your eye and create a "map" of your cornea.
• With wavefront technology associated with custom LASIK, you also are likely to undergo a wavefront analysis that sends light waves through the eye to provide an even more precise map of aberrations affecting your vision.
• Your eye doctor will also note your general health history and any medications you are taking to determine if you are a suitable candidate for LASIK.
• You should stop wearing contact lenses for a period of time advised by your doctor (typically around two weeks) before your eye exam and before the LASIK procedure, as contacts can alter the natural shape of your cornea.

What To Expect During LASIK

Before your surgery begins, numbing eye drops are applied to your eye to prevent any discomfort during the procedure. Your doctor may also give you some medication to help you relax.

1. Your eye will be positioned under the laser, and an instrument called a lid speculum is used to keep your eyelids open.
2. The surgeon uses an ink marker to mark the cornea before creating the flap. A suction ring is applied to the front of your eye to prevent eye movements or loss of contact that could affect flap quality.
3. After the corneal flap is created, the surgeon then uses a computer to adjust the excimer laser for your particular prescription.
4. You will be asked to look at a target light for a short time while he or she watches your eye through a microscope as the laser sends pulses of light to your cornea.
5. The laser light pulses painlessly reshape the cornea, although you may feel some pressure on your eye. You'll also hear a steady clicking sound while the laser is operating.

LASIK is performed on each eye separately, with each procedure taking only about five minutes.

Immediately After LASIK Surgery
Upon completion of your LASIK surgery, your surgeon will have you rest for a bit. You may feel a temporary burning or itching sensation immediately following the procedure. After a brief post-operative exam, someone can drive you home. (You cannot drive after LASIK until your eye doctor sees you the following day and confirms your uncorrected vision meets the legal standard for driving.)

• You should expect some blurry vision and haziness immediately after surgery; however, clarity should improve by the very next morning.
• Your eyesight should stabilize and continue to improve within a few days, although in rare cases it may take several weeks or longer. For most people, vision improves immediately.
• You may be able to go to work the next day, but many doctors advise a couple of days of rest instead.

Also, it is usually recommended that you refrain from any strenuous exercise for at least a week, since this can traumatize the eye and affect healing.
Generally, you will return to see your eye doctor or your LASIK surgeon the day after surgery.
At this initial check-up, he or she will test your vision to make sure you are legal to drive without glasses or contact lenses. In most states, this requires uncorrected visual acuity of 20/40 or better.
As with any other surgery, always follow your doctor's instructions and take any medication prescribed. Also, avoid rubbing your eyes, as there's a small chance this could dislodge the flap until it heals and adheres more securely to the underlying cornea.


Long-Term Results
Laser eye surgery offers numerous benefits and can dramatically improve your quality of life. Most people achieve 20/20 vision or better after the surgery, but LASIK results do vary. Some people may achieve only 20/40 vision or less.
