Lasik

How old do I have to be for laser vision correction?

You need to be over 18 years of age, and your glasses or contact lens prescription should not have changed in the last year. If your eye is still changing from year to year, you should not have the procedure until the cornea is stable.

Isn’t all laser vision correction the same?

No. Many of the discount LASIK centers want you to believe that LASIK should be purchased like a commodity and that surgeon experience, lasers, diagnostic technology and follow-up care don’t matter. Laser vision correction will affect the way you see for the rest of your life. You should make your decision to have laser vision carefully, not quickly. Our Web site has a lot of information about our surgeons, our laser technology, our advanced diagnostic technology and what you should expect for the money you spend. We provide you with all of this information because we feel the more you know about us, the more confident you will feel about choosing us as your laser vision correction provider.

What are the diagnostic tests done before one can undergo LASIK procedure?

Besides routine eye examination two preoperative tests viz. Topography Test & Pachymetry Test need to be performed. Topography Test is done to map the refractive power of the cornea and to rule out certain corneal conditions like conical cornea, etc. The Pachymetry Test is done to measure the thickness of the cornea.

Will the procedure hurt?

There is no pain during any of the laser vision procedures since anesthetic eye drops numb your eyes, although some patients may experience mild discomfort or a pressure sensation during their procedure after LASIK, you might experience mild irritation for a few days after your procedure. An over-the-counter pain reliever or use of artificial tears will generally take care of this discomfort.

Will I need glasses after LASIK?

If thoroughly evaluated and performed in the right candidate with the latest technology, patients who have LASIK do not generally require glasses for most activities. However, patients who are over the age of forty must wear reading glasses after LASIK (if both eyes were corrected for clear distance vision). Some patients will choose “Monovision”, in which one eye is corrected for distance and the other eye is corrected for near. Whether you are a candidate for Monovision will be determined during your consultation.

If I choose to have monovision, does that mean I’ll never need reading glasses?

Not necessarily. The effects of presbyopia continue to worsen as you get older, whether or not you have monovision. At some point in time, reading glasses or another vision correction procedure may become necessary. The benefit to having monovision is that there won’t be a complete dependence on glasses for close vision. Many who have monovision are able to see well enough both at distance and near to do things at any age without corrective lenses.

Can I have both eyes operated upon at the same time?

This is what we recommend. It has been demonstrated in several large, clinical studies that LASIKs results and safety are identical whether the procedure is reformed on both eyes simultaneously versus one eye at a time. Most patients elect to have both eyes operated upon the same day out of convenience, less time out of work, and avoiding imbalance between the two eyes.

How long does the procedure take?

Once in the laser room your eyes will be cleaned and prepared for surgery. The surgery itself usually only takes five minutes or so per eye, however the preparation process of surgery may vary between 3 to 6 hours depending on technology and procedure chosen.

What keeps the flap in position?

Following your procedure, the flap stays in position without the need for stitches. Initially, there is a vacuum effect created by the cells lining the inner surface of the cornea. As the eye heals over the first few days, the epithelium (the outer surface of the cornea) seals the edges of the flap.

Will I have 20/20 vision following laser vision correction?

The goal of any refractive surgical procedure is to reduce your dependence on corrective lenses. However, we cannot guarantee you will have 20/20 vision as a result. Our commitment to you is that we will not perform laser vision correction on you or anyone we feel does not have a good possibility of achieving independence from glasses and contacts. The vast majority of our patients are extremely happy with their results and can do most activities without dependence on corrective lenses after laser vision correction.

Is laser vision correction safe?

There are possible risks with any surgical procedure. Serious complications with LASIK are extremely rare. The chance of having a vision-reducing complication from LASIK has been documented in clinical studies to be less than one percent. Many of the risks and complications associated with this procedure can be reduced or eliminated through careful patient selection and thorough pre-operative testing using the latest diagnostic technology. After laser vision correction, you may experience some visual side effects. These are usually mild and most often diminish over a few days to a few weeks. But there is a slight chance that some of these side effects won’t go away completely, such as feelings of dryness, glare and halos. If after a thorough examination we decide you are a good candidate for laser vision correction, you will be given additional information about the procedure that will allow you to make an informed decision about whether to proceed. Be sure you have all your questions answered to your satisfaction.

What about nighttime side-effects?

You have probably seen news stories about people having difficulty driving at night after refractive surgery. Nighttime side-effects may include halos, starbursts, and glare around lights and blurry vision. Some of these can be caused by overcorrection, undercorrection, or residual astigmatism and higher order aberrations (imperfections). These effects usually diminish as the eye heals in the first three to six months. Sometimes additional touch-up (enhancement) procedures will be recommended or the doctor may recommend Wavefront procedure to minimize these side effects. Another possible cause of nighttime side-effects is pupil size. At night, the pupil expands to let in more light. Light coming through the peripheral cornea may be out of focus if the pupil opens beyond the laser treatment area. This is why some patients are not good candidates for LASIK, if they have very large pupils. However, our advanced laser technology has expanded treatment zones to the widest optical zone therefore patients that were at one time not candidates for LASIK because they had large pupils, can now be treated.

How long will the results of the surgery last?

Laser vision correction is considered to be permanent. However, your eyes can still change as you age which may cause a need for glasses or contacts or additional vision correction procedures in the future. As people reach their early forties, they develop presbyopia and begin to need reading glasses. If you’re over 40, you may want to consider monovision.

What if I move my eye during the laser treatment?

While the treatment is performed, you will be asked to look at a light under the laser. You are required to look steadily at the light throughout the operation, since this keeps the eye centered under the laser. However, if you temporarily look away or lose the ability to look at the fixation light, do not be concerned. The WaveLight Allegretto Laser is equipped with a special eye tracker that tracks the eye at 400 times a second throughout the procedure.

Do I have to go without my contacts before having laser vision correction?

If you are wearing hard or gas permeable contacts, it’s important that you remove them at least three weeks prior to your exam. Soft lenses should be out for at least one week before your exam. Soft toric lenses may need to be out longer. Your doctor will advise you how long you need to be out of your contacts prior to your exam and prior to your surgery.

Does LASIK cause dry eye?

Following a LASIK procedure, every patient has temporary dry eye, which can be treated most often with artificial tears. This dry eye sensation usually clears up in eight to 12 weeks except in rare cases, where it may take longer. Patients with pre-existing dry eye may not be good candidates for LASIK. If you have dry eye, you should discuss it with your doctor at your pre-op examination. Tests can often diagnose dry eye but it is still somewhat difficult to predict who will experience significant dry eye following LASIK. A thorough evaluation of your current medications, medical history and work environment should all be taken into account.

What will my recovery be like?

Most LASIK patients usually see quite well the day following their procedure and may be able to resume most of their normal daily activities, but patients with higher prescriptions may recover more slowly. Although the speed of visual recovery depends on personal healing patterns, most patients notice dramatic visual results within the first few days following their procedure.

Can I have laser vision correction while I am pregnant or trying to conceive?

Pregnancy can affect your vision, therefore if you are pregnant or trying to conceive, you should not have laser vision correction. You should wait several months after your pregnancy or after you finish nursing before having laser vision correction.

Can I drive home after the surgery?

No, you will need a designated driver! For the first couple of hours your eyes will be sensitive to light and the vision blurred, so you should wear the special dark glasses that we provide.

I have a “lazy” eye; can I still have LASIK to correct myopia?

Lazy eye encompasses a wide range of visual problems and levels of visual acuity. The only way to know for sure if you are a candidate for LASIK is to come to the office for a consultation with our expert doctors for a thorough evaluation to determine if LASIK will help you. Many patients with lazy eye have enjoyed their results following LASIK because they no longer need glasses or contact lenses to achieve their best acuity.

My son has kerataconus and I would like to know if he is a candidate for laser eye surgery.

Laser vision correction is not suggested for patients with keratoconus. However, it is important to treat this condition to prevent it from progressing. Our very sensitive topolyzer grades the keratoconus and gives us the right treatment plan and rigid contact lens fit.
