Can I see the scenery clearly without glasses or contact lenses? Millions of people have undergone LASIK laser eye surgery to improve their vision. This is a popular surgical procedure with a high success rate that can improve your quality of life. If you are tired of glasses or troubled by contact lenses, LASIK eye surgery may be for you. Whether you are nearsighted, farsighted or astigmatism, LASIK is a ten-minute quick operation that can improve your vision. But not everyone will benefit from LASIK. You should know that LASIK is a medical procedure.
What is LASIK Laser Eye SurgeryLASIK is an eye surgery used to correct myopia, hyperopia and astigmatism. The operation is performed by an ophthalmologist using a laser. Approximately three million procedures are executed each year. LASIK is been known as the abbreviation for laser-assisted in the situ keratomileusis.
Vision defects are caused by irregularities in the cornea (the transparent front cover of the eye). This changes the way the cornea focuses the light entering the eye. LASIK eye surgery can correct these vision defects by reshaping the cornea. LASIK eye surgery cannot correct presbyopia, so people over 40 still need reading glasses.
During LASIK, a flap is cut on the outside of the cornea and folded back. Then use an excimer laser to reshape your cornea. The laser will not burn or cut, but will vaporize the tissue under the cornea. The removed tissue layer may be only ten microns thick. Next, put the flap back in place to heal the eyes.

Prepare for Eye Surgery and RecoveryA few weeks before surgery, contact lenses should be stopped. Your surgeon will examine your eye, measure its surface contour, and calculate the amount and location of corneal tissue to be removed.
LASIK is an outpatient surgery and you will stay awake during the operation. Use anesthetic eye drops and antibiotics. Sometimes you will get sedatives. The metal speculum opens your eyelids. Your vision will be blurred during the operation. After that, the corneal flap remains naturally adhered without sutures. Most people will immediately notice an improvement in their vision. In the next six months, your vision may continue to improve.
Note that you don't need to drive or work after laser eye surgery. It is been advised to take at least two days off to recover your health. As your eyes return to health, you will be asked to rest and stay in the dark. You will get the use of antibiotics and anti-inflammatory eye drops. Eye drops will also help moisturize the eyes. The eye mask can protect your eyes from strong light. Sleeping goggles prevent you from rubbing your eyes while you are asleep. You will have some discomfort and may not see clearly after a few days.
Is LASIK Laser Eye Surgery Right for you?There are several reasons why you are not suitable for LASIK eye surgery. The ideal LASIK patient is over 21 years old and has stable vision. If your sight changes frequently, LASIK will not work properly. If you are under 21, your eyes will still change rapidly and LASIK will not work well. If new glasses prescriptions are often needed due to changes in vision, then you are not the ideal candidate for LASIK laser eye surgery. Pregnancy and nursing can also change your vision.
For successful LASIK surgery, your eyes should be healthy. If you suffer from dry eye, large pupils, thinning of the cornea, or poor eye health, your doctor may decide not to recommend LASIK. Certain medications, such as hormone replacements, antidepressants, steroids, and antihypertensive drugs, may cause dry eyes or changes in vision. If you participate in contact sports, LASIK may not be recommended. Eye diseases such as glaucoma or high intraocular pressure may rule out LASIK eye surgery for you. Your doctor is your best advice for LASIK eye surgery.

Do You Know the Risks of LASIK Laser Eye Surgery?Most patients are very satisfied with the results of LASIK laser eye surgery. But all operations have risks. Although LASIK can usually be used to correct vision to 20/20, temporary complications may occur. Your doctor will need to perform follow-up tests to check for abnormalities.
After the operation, some patients noticed that the image was not as clear as when wearing glasses. This means that the eyes are temporarily less sensitive to the contrast between light and dark. Some patients experience temporary dry eyes, which can cause glare and halos. Some night vision capabilities are temporarily reduced. Other patients become more sensitive to light. The patient may get inflammation or infection. These symptoms can be cleared by medical treatment, and gradually disappear as the eyes heal.
However, if surgery results in over-correction or under-correction of vision, additional surgery must be performed within 3 to 6 months to enhance vision. Some patients may notice that over time, mild nearsightedness or farsightedness gradually recovers. This is called visual regression. Repeated LASIK surgery can offset this regression. It is also possible that the vision cannot be corrected or even deteriorated. In this case, glasses must be worn.
How much does LASIK Laser Eye Surgery Cost?The cost of LASIK eye surgery varies by surgeon and state. The cost ranges from $1500 to $7000 per eye. Don't choose a doctor based on cost alone, but based on the quality of care you get. Your doctor should take time to answer your questions. Choose a doctor who has done many LASIK eye surgeries and received equipment training. Determine whether the cost includes all preoperative and postoperative visits. Ask if you can choose your surgeon or assign a surgeon on the day of the operation. If complications occur, does the cost include emergency care? You or the doctor, who will determine if a second surgery is needed, called augmentation surgery? Also, if you need intensive surgery, can you pay for it?
In the United States, LASIK laser eye surgery is considered elective surgery and is usually not covered by medical insurance. Please contact your insurance company for details. If you have participated in a medical cafeteria plan or a medical stretch plan through your employer, you can save money by paying LASIK in pre-tax dollars. You should also ask your tax advisor whether the cost of LASIK eye surgery can be deducted from the federal income tax return.
Other Techniques of Laser Eye SurgerySince LASIK was first used in 1990, laser eye surgery has made progress. These are the other five procedures of laser eye surgery.
- Wavefront LASIK is a breakthrough technology for customized LASIK surgery with better results. It uses precise three-dimensional measurements to measure how your eyes process images. People with poor night vision, poor contrast sensitivity and glare will benefit from Wavefront LASIK. Traditional LASIK cannot solve these problems. Now, most ophthalmologists use Wavefront LASIK.
- Intralase is a modification of LASIK eye surgery. It uses a machine-guided laser instead of a hand-held blade to cut the flap into the cornea. You can call it a bladeless LASIK. Some patients feel more confident in computer-controlled bladeless cutting.
- PRK or photorefractive keratectomy is another type of laser surgery that can be used to correct myopia, hyperopia, and astigmatism. Ophthalmologists who use PRK will not cut thin flaps on the ocular surface like LASIK surgery. Instead, laser energy is applied directly to the surface of the eye. In the PRK process, the ultra-thin outer layer of the eye (epithelium) is completely removed by laser energy and eventually grows up. PRK is a successful surgical method, but LASIK has less discomfort and results faster.
- The LASEK program is different from LASIK. With LASEK, a very thin epithelial layer can be lifted from the surface of the eye, and then laser energy is applied for shaping. After LASEK surgery, the epithelium is replaced with the surface of the eye. This is a relatively new procedure that can be achieved with a hand-held cutting tool called trephine and is suitable for patients with thin corneas.
- Monovision LASIK is now available. Everyone develops presbyopia after the age of 40 and needs to wear reading glasses. To avoid wearing reading glasses, some people have undergone LASIK eye surgery for correction. Surgery corrects one eye to see very far, while surgery corrects one eye close and middle distance. Monovision will reduce depth perception, but many people are satisfied with this operation. Without surgery, you can get a prescription for glasses or contact lenses
