How can you find a good Lasik surgery center?

Lasik eye centers are very popular and can be found worldwide. You can check you phone books for eye centers in the area you are living. You could also ask co workers or friends that may have had work done to see where they went to.

What are the symptoms of dry eyes?

Causes of dry eye syndrome before or after LASIK include:

  • Older age, particularly if you are female and have undergone menopause.

  • Allergy medications (antihistamines), certain blood pressure medications and anti-depressants that can decrease eye moisture.

  • Autoimmune diseases such as Sjogren's syndrome.

  • Unusually dry climates or environments, such as a room that is highly heated or air-conditioned.

How is laser eye surgery performed?

LASIK surgery is done by creating a flap of corneal tissue with a blade or laser, exposing the corneal tissue under the flap that needs to be treated, reshaping the cornea by removing tissue with the Eximer laser and laying the flap back in place for the tissues to heal. To determine if someone is a suitable candidate for LASIK surgery, an eye surgeon must be consulted. For other concerns, you may visit http://www.about-eyes.com/ or CataractCoach@twitter.com. Thanks for asking.

What is involved in refractive eye surgery?

"Refractive eye surgery is also known as laser eye surgery. It removes the first layer over the eye that keeps you from seeing as well, making you not need glasses."

What causes post menopausal fluid in uterus?

In post menopausal women, the cervical opening often thickens and may close alltogether. This is called 'cervical stenosis'. This may be caused by scarring from previous endometrial ablations or from growing fibroids which are benign tumors inside the uterus or the uterine wall. Fluid may collect inside the uterus because it cannot travel out of the constricted cervical opening. This is usually detected by ultrasound. Your doctor may request an 'endometrial biopsy' which is a procedure involving gently dilating the cervical opening and removing tissue for examination by a pathologist. The tissue will be examined for cancer cells. Just going through this procedure may be enough to have the fluid drain since the cervix will be opened wide enough for the small biopsy tube. If the fluid, pelvic pain, pressure, or other symptoms are not resolved by this procedure, the next step is a D&C (dilation and curettage) which is the gentle removal of tissue inside the uterus....a more involved procedure.

How expensive is the average Lasik surgery?

The cost of laser eye surgery will greatly depend on factors such as insurance as well as the specific procedure being performed. Laser eye surgery, however, can cost anywhere from several hundred dollars up to ten thousand dollars.

How safe is laser back surgery?

Laser surgery is generally safe and is far less traumatic to the body than traditional surgery methods. Whether laser back surgery is effective depends on the patient.

When did laser eye surgery begin?

Who knows? Eye surgeries, especially cataract removals are some of the oldest surgical procedures that exist, stretching back to Biblical times.

Will your voice ever get back to normal after laser throat surgery to remove a polyp on the side of the larynx?

Yes it will. Try to force your voice to much. Like any surgery it will take time to heal. If you have further questions it's best to discuss them with your doctor.

What if you have really small eyes can you make them bigger with surgery?

No. It is not possible to make your eyes bigger. However, effective use of make-up can give the illusion of bigger eyes. Try a thin line of liquid liner on the upper rim of your top eyelid, as close to the lashes as you can get and a pencil liner just beneath your lower lid. Don't line the inside rims of your eyelids, this will make your yes appear smaller.

What does laser iridotomy treat?

Laser peripheral iridotomy makes an opening in the iris allowing the fluid to drain, argon laser trabeculoplasty is aimed at the fluid channel opening to help the drainage system function.

How can lasik surgery help color blindness?

Color blindness is a problem with the retinal receptors in the back of the eye and LASIK in no way can help this problem.

What are the pros and cons of laser eye surgery?

The positive health benefits of Laser eye surgery is that it takes shorter period of time to finish, it is effective and less invasive and it has a pretty good success rate of good prognisis.

Does lasik cause presbyopia?

Lasik surgery is advised around the age of 20 ; by that age, the power stabilises.

After Lasik, the remaining power is given in glasses. Never expect 100% correction

by Lasik. The problem of presbyopia starts around 40 and one has to wear

glasses. New types of operations are now done to correct correct presbyopia.

How does a laser hurt your eye?

Well, If you have ever looked into the sun and then looked away (please don't if you haven't!) You will see e series of purple and green dots. This is from the sun, a laser in itself, burning your eye. You may not feel it but it does cause damage. Remember to wear eye protection. imagine a laser closer to you and stronger then the sun. it would blind you!!!

Why was LASIK invented?

This simple question is profound, because it touches on an invention that has changed the way in which the world views vision correction and has helped millions of people worldwide to see better without the aid of glasses or contact lenses.

For perhaps millions of years, much of human kind has suffered with vision problems. There are the serious eye diseases such as cataracts, glaucoma and a myriad of other problems. Beyond this is the simple fact that many people are unable to see clearly at distance, near, or both. This is from the imperfections of the eyeball as a camera and this was greatly helped over that last few hundred years by glasses and more recently in the last 50 years by contact lenses. Although with the advent of lasers, there was a hope that such technology could improve vision, limitations in the nature of the eye had limited laser application to vision correction until the advent of LASIK.

LASIK is a hybrid procedure, that is it involves two steps which together are able to improve vision very rapidly and predictably for patients with ametropias. The first step is to create a potential space for the laser to correct the vision and the second is to do the correction itself. In the early days of LASIK about 15-20 years ago, this potential space was made with a device called a microkeratome. This is a miniature shaver which can peel a thin layer of outer tissue from the cornea which remains attached at the edge or "hinge". Another laser, the excimer laser then focuses on the freshly cut surface, and removes tissue in a programmed manner to reshape the eye. Finally, the flap is replaced which assumes the contour of the newly shaped cornea beneath it. It is the transfer of the shape combined with covering the treated area with living tissue that makes LASIK so remarkable. Healing occurs at the edge or seam of the flap and the eye barely knows that anything has occurred beneath. The vision is rapidly restored with no significant healing response, which is key to the success of LASIK.

Newer lasers, called femtosecond lasers, are able to make the flap layer more precisely without a cutting blade but fundamentally perform the same function. This all laser approach is a safer and slightly more effective way of restoring vision by LASIK.

We become complacent very quickly with new technologies but it is a truly amazing and revolutionary accomplishment that in a procedure that lasts only a few minutes, a persons vision can be corrected from a lifetime of limitations.

Why are eyes called eyes?

Private eye: Noun slang.

Meaning: A private detective.

Origin: 1935 -1940; eye, an allusive phonetical rendering of I, the abbreviation of investigator.

Case closed.

How do you cure mixed astigmatism?

LASIK is a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. In LASIK, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser. The surgeon folds back the flap, then removes some corneal tissue underneath using an excimer laser. The flap is then laid back in place, covering the area where the corneal tissue was removed.

With nearsighted people, the goal of LASIK is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. LASIK can also correct astigmatism by smoothing an irregular cornea into a more normal shape.

Does lasik eye surgery have a lot of risks?

Lasik eye surgery do carry some risk. The most dangerous is losing your eyesight. Fortunately, that is extremely rare. There are cases where you end up being worst off and then there are minor issues like dry eyes and halo effects.

What are the risks if opting for laser spine surgery?

There are several dangers to spine surgery since the spine is a vital, complex, and sensitive bone in our body. During surgery, your spinal cord could be damaged, which can lead to nerve damage involve different conditions such as paralysis. If the surgery is to relieve pain, the surgery can actually end up causing more pain or chronic pain. Spinal surgery is very stressful on the body which can lead to future pain, can lead to blood clots, and ruptured discs. It is best to discuss the dangers with your doctor at your convenience.

Can astigmatism be corrected?

Laser correction surgery can be performed on people with an astigmatism, but check with your eye care professional. Depending on what needs to be corrected, some cases may not be good candidates.

Does lasik eye surgery really work?

It can't cure actual blindness.

It might potentially be able to cure certain types of legal blindness (defined as having vision worse than 20/200 with the best possible correction).

What happens if you squeezed your eyes too hard after lasik?

As long as the eye has had ample time to heal following the surgery, usually nothing happens. There are some eye traumas, though, that can relift the flap that is created in the LASIK surgery. For that reason, there are certain people I recommend not get LASIK surgery b/c of their profession, most notably boxers. There are also freak accidents that may relift the corneal flap as well (like a patient who was hit in the eye with the edge of a 2x4). When this sort of accident occurs, we simply lay the flap back in place and give it time to heal. On the same note, the military used to prohibit LASIK in their pilots because of the fear that the G-force created in high speed planes would dislocate the flap. With the introduction of the Intralase laser, the military not only allows LASIK but performs it routinely on pilots.

Can lasik surgery correct vision to 20 10?

It's possible, but not likely. LASIK surgery changes the natural shape of the eyes by ablating (removing) part of the cornea to change a person's prescription. When changing the natural shape of the eye, this induces what are called higher order aberrations. (ie - spherical aberration, coma aberration, etc. ) These aberrations make seeing 20/10 nearly impossible. I have seen patients with 20/15 results, but it's not usually a crisp 20/15, and usually results in a slight fuzziness or haze around letters and halos around car headlights/streetlights at night.

Can you have eye surgery if you have a cold?

Yes, you can. Common cold isn't an absolute contraindication for surgery. However, if viral infection affects the lungs, the surgery should be postponed.
