Laser Eye Surgery: What Happens And Why

Laser eye surgery often called lasik eye surgery, is a procedure that allows your eye sight to be corrected. There are actually many different types of this surgery and the equipment often changes from one doctor to the next. What the overall benefit is, though, is simple. By adjusting the shape of your cornea, you can improve your eye sight considerably. Like any other surgery, there are risks involved. But, the benefits are there for most that have laser eye surgery.

The cornea of your eye is the film of tissue that covers your pupil. In a normal eye with no vision problems, it has a very specific shape that is even and rounded. In an individual that has near sightedness or far sightedness, the cornea is misshapen to some degree. By bowing out or changing shape in just a bit or a lot of area, the cornea distorts your vision, which leaves you with problems like not being able to see things that are far away or being unable to see things up close.

With the help of laser eye surgery, though, this can be changed. The doctor will remove part of the cornea from your eye on only three sides, creating a flap. From here, he will use a high powered laser to change the shape of the stroma, which is the tissue that lies under the cornea that?s been removed. By shaving that to the desired level, he improves your vision. When the cornea lays back over the eye, it now lays there correctly, with the right curve which ultimately improves your vision.

The laser eye surgery procedure is one that should be carefully considered because there are some risks. But, if the procedure goes correctly, within some time after healing has been complete, your eyes can actually improve in vision. Some individuals gain excellent eye sight. Others improve. Talk to your doctor about the benefits that can come from your improvements.

Are You A Bad Candidate For Lasik Eye Surgery?

Lasik eye surgery is not the right thing for everyone. Although there are many individuals that can see remarkable improvement with eye surgery, some are just not the right candidates for the job. That?s because of the eye conditions or the risks that they face. The eye surgeon that you are working with will talk with you specifically about your actual benefits versus the risks of lasik. They will also tell you if you even are a person that can consider having lasik eye surgery at all.

Some of the reasons why lasik eye surgery may not be right for you include these.

? If you are talking medications like steroids or medications that will limit the healing that your body can do, you may not qualify.

? If the costs are too high and you simply do not have coverage with your insurance company, you too may be limited.

? If you have an autoimmune disease or some other type of major illness or chronic condition, you may not qualify. This will depend on what condition you have.

? If you have a prescription for glasses that is quite strong, have a prescription that changes often, or you have a need to wear your glasses only some times, you may not qualify.

? If your career depends on your eye sight, you may want to consider your options closely.

? Your eye?s physical condition may also make a difference. Things like the pupil?s size, the amount of tear production that you have as well as the corneal thickness that you experience, all matter.

Although many individuals are the perfect candidate for lasik eye surgery, others have other conditions that stop them from having lasik performed. Your doctor will work with you to determine your level of risk and ability to have it before making any promises to you.

LASIK Eye Surgery: A Definition

The word LASIK means ?Laser-Assisted In Situ Keratomileusis.? In situ is latin and means to deal with a phenomenon in place where it occurs, as opposed to outside of it?s environment. Keratomileusis is a surgical improvement of the refractive state of the cornea. It is performed by lifting up the front surface of the eye by forming a thin hinged flap, under which the shape of the cornea is changed by using some type of surgical device.

Excimer Lasers

LASIK eye surgery is therefore surgery that is done in order that a person who wears glasses or contact lenses should no longer be completely reliant on them to see. It is a medical procedure undertaken by a qualified opthamologist. The aim is to modify the shape of the cornea (the clear covering of the front of the eye) through use of an excimer laser. An excimer laser is a type of ultraviolet chemical laser that is unusually well focussed and capable of highly delicate control. Instead of burning away or cutting materials, an excimer laser intrroduces sufficient energy to disrupt molecular bonds of surface tissues. Effectively the tissue disintegrates in a controlled fashion through ablation rather than burning. Excimer lasers can remove very thin layers of surface material with almost no heating or change to the material which is left behind.

Flap Creation

When LASIK surgery is performed, a knife known as a microkeratome is inserted into the cornea and cuts a flap of skin. A human cornea measures from around 500 to 600 micrometres in thickness; the microkeratome creates a 100 to 200 micrometre thick flap. At one side of the flap is left a small piece of skin known as a hinge. The flap of skin is then gently folded back to show the stroma (otherwise known as the middle area of the cornea).

There are two types of microkeratomes currently in use, mechanical and laser. Both are affixed to the eye by use of a 360 degree vacuum ring, flatten the cornea with a clear plate, then cut the cornea underneath the plate.

Mechanical microkeratomes use a sharp thin metal blade. Laser microkeratomes are used in the IntraLasik procedure. They employ amplified light energy to form thousands of minute bubbles at a predetermined depth. These bubbles of water and carbon dioxide connect with each other create an incision.

Reshaping the Stroma

A laser that is controlled by a computer is then used to disintegrate a part (but not all) of the stroma and after that is finished, the flap of the cornea is fixed up and put back into place. New and more advanced ways of performing LASIK surgery are being looked at all of the time.

The purpose of eyeglasses and contact lenses is to compensate for the weaknesses of the eyes and to allow for vision that is as clear as can be. LASIK is a form of refractive eye surgery that is geared towards improving the eye?s ability to focus and not just focus, but also focus well on any object. When it comes to LASIK surgery, a laser is used to remove part of the tissue of the cornea and then it is reshaped in order to improve its ability to focus.

Lazer Eye Surgery: The Real Percentages

Lazer eye surgery is not lazer perfect. Although there are a number of people that will get the best possible results, there are also a few that won?t have the best results. If you considering an eye surgery that will provide you with the tools that you need to stop wearing glasses, or even better to stop have to deal with the problems of contact lenses, you need to know the truth. How often is it possible for patients to get 20/20 vision with the use of lazer eye surgery?

The problem with getting a straight answer is that you often have to understand what the options are and what the likely outcomes are. You see, there are a number of factors that play into what your results will likely be. For example, there are a number of different, FDA approved lazers that can be used to treat eye conditions. Each of these has a different success rate. In addition, the extent to which you have an eye condition also matters as well as the eye condition in the first place. Each has a different benefit possibility.

You can visit the FDA website to learn about the specific benefits and results based on a number of these factors if you like. The best way for you to find out what your benefits are likely to be is to talk with your doctor. Doctors can examine your eyes, see what your specific needs and conditions are, and then access your specific possibilities. While you can get some basic information from that website, your doctor will know better about your condition.

Lazer eye surgery is something that you can consider, but you should know the benefits you are likely to earn. You?ll find that many individuals will have excellent results. Talk to your doctor to learn what he can offer to you.

The Popularity Of Lasik Eye Surgery

There are few among us who, at one time or another, had not had to manage some level of impaired vision. Whether age has rendered us no longer able to see far away or up close, or we have suffered an illness or disease that has compromised our vision, it is likely that, if we have not already, we will someday need corrective measures to help us see at our best.

And for those who have long managed the expense and inconvenience of eyeglasses and contact lenses, the idea of corrective eye surgery seems most appealing. It's no wonder, therefore, that Lasik eye surgery has continued to grow in popularity since it was first performed in the United States in 1991.

Lasik is relatively new on the scene to us ? the consumers; but in actuality the technology has been a long time coming. In fact, in 1948, Columbian ophthalmologist, Jose Barraquer first experimented with corneal procedures by actually surgically removing more than half of a patient?s cornea that he then froze. Once the cornea had been frozen to an appropriate temperature, Dr. Barraquer was able to reshape its surface thus removing barriers to clear vision.

Once the cornea had been reshaped it was replaced into the patient?s eye. Such technology evolved by the 1960s to the point where such corneal procedures could be done without removing the cornea from the patient?s eye; this procedure was perfected and performed in Russia and involved the use of a scalpel.

Lasik began to take shape in the early 1980s when a U.S. ophthalmologist made alterations to laser technology that had begun to be used by the U.S. military. But in 1990, Lucio Buratto and Ioannis Pallikaris developed the Lasik surgery that we know today by combining methods of two pre-existing techniques ? keratomileusis and photorefractive keratectomy. Both keratomileusis and photorefractive keratectomy are techniques in which the cornea is reshaped with the use of an excimer laser or other technology.

The word Lasik refers to Laser-Assisted In Situ Keratomileusis and is a form of refractive laser eye surgery that was first performed in the United States in1991. During the procedure, the patient?s eye is immobilized with the use of a cornea suction ring after which the surgeon creates a flap through an incision made in the top layer of the corneal tissue.

The flap is then lifted back to reveal the mid-section of the cornea ? known as the stroma. The surgeon then uses a low-powered excimer laser to resurface the stroma. The corneal flap made during the procedure is then replaced over the stroma; the healing process is natural and generally speedy. The procedure itself is very quick ? usually less than 10 minutes an eye ? and virtually painless. The most discomfort experienced by the patient is general anxiety in anticipation of the procedure.

Today, over one-million people in the United States alone have undergone Lasik surgery ? generally with very good success. In fact, it is a very small percentage of patients ? less than 6% - who have experienced any complications following their procedure. Such complications generally include light sensitivity, dry eye, double vision, and scarring. These incidences, however, are very rare and can be greatly reduced by having your procedure performed by a reputable and experienced surgery center.

Finding Reputable Lasik Eye Surgery In New York

As more and more people choose to seek alternatives to pricey and inconvenient eyeglasses and contact lenses, the popularity of Lasik eye surgery continues to grow exponentially. The Lasik procedure was first performed in the United States in 1991; today over one million people in the U.S. have undergone the procedure. For patients looking to embark on Lasik, finding a reputable surgery center is paramount to achieving success.

For those living in the New York area, reputable Lasik eye surgery in New York is relatively easy to find. In such a populated area ? and one that is a medical hub of the east coast ? Lasik has been made available to the masses.

Lasik eye surgery works to repair the way in which our eyes refract light. In a normally functioning eye, the lens of the eye works to refract ? or bend ? light to the retina. The retina ? a group of cells in the lining in the back of the eye then takes that light and converts it to messages that can be understood by the optic nerve of the brain. The optic nerve receives these messages as visual images. When one link in the chain is affected the end result changes ? much like the childhood game of Whisper Down The Lane.

In the case of refractive disorders such as nearsightedness, farsightedness, and astigmatism, light is not refracted properly to the retina. In turn the message that the retina sends to the optic nerve in the brain is received as a blurry image. Lasik surgery corrects the way in which we refract light through the use of laser technology.

During a Lasik procedure the eye is numbed, held open with a speculum, and immobilized with a corneal suction ring. After immobilization, the surgeon cuts a small incision in the top layer of the cornea making a flap. The flap is then folded back and the surgeon is able to access the underlayer of the cornea known as the stroma.

A low-powered laser is used to resurface the stroma so that light is refracted correctly going forward. After the laser procedure, the flap is replaced over the eye and allowed to heal naturally. Such a surgical procedure ? while completed quickly ? requires enormous precision and skill by experienced surgeons. Those undergoing Lasik eye surgery in New York often have little problem finding reputable and experienced surgical centers.

Ultimately, finding Lasik eye surgery in New York requires some research from the prospective patient. Those living in the New York area can often get a referral from their regular eye doctor or primary physician. But often the best way to find reputable Lasik eye centers is through a recommendation by someone who has had the procedure performed.

Talk to people who you know to have had the procedure and ask questions regarding their particular experience ? including comfort level, respect received by the staff, the way in which surgeons addressed their questions and concerns, billing procedures, and aftercare.

Make sure to conduct your own research when it comes to finding Lasik eye surgery in New York; visit surgical centers in which you are interested and interview the surgeons to make sure that you are compatible with them on a personal and professional level. Ultimately ? no matter where you have your procedure performed ? you should feel as if you have been educated thoroughly regarding the procedure and have had all your questions answered.

The Rise Of Lasik Eye Surgery

The days in which eyeglasses and contact lenses were the only option to those with impaired vision came to an end in 1991 when Lasik eye surgery was first performed in the United States. Today, with more than a million patients having undergone the procedure, Lasik has become commonplace among eye patients who wish to minimize the long term expense and inconvenience associated with eye care. Lasik is something of a miracle for those who have struggled with compromised vision. And while it may be something that is relatively new to us, it utilizes technology that has actually existed for quite some time.

Lasik eye surgery focuses on the reshaping of the eye?s cornea ? the transparent tissue that covers the iris (the colored segment of the eye) and the lens (the part that rests behind the iris). The lens is the part of the eye that bends or refracts light to the retina ? cells that exist in the lining of the back of the eye. The retina?s job is to then take that light and convert it to messages that can be received by the optic nerve in the brain.

When the eye experiences refractive difficulties ? such as what is experienced in nearsightedness, farsightedness, astigmatism, and a host of other issues ? the light that our eye receives is not refracted properly and the message that our brain receives is that of a blurry image. Traditionally, eyeglasses and contact lenses have been utilized to correct how light is refracted by our eye. But modern times have seen the rise in popularity of Lasik eye surgery ? that makes such corrections with the aid of a laser.

Experimentation with surgically correcting the cornea first began in the late 1940s when a Columbian ophthalmologist was able to successfully treat patients by removing over half of their cornea, freezing it, resurfacing it once it was frozen, and then replacing it in the patient?s eye. In the 1960s, an ophthalmologist in Russia was able to elevate the technology by making adjustments to the cornea while it remained in the patient?s eye; such adjustments were made using a scalpel.

In 1990, Lucio Buratto and Ioannis Pallikaris developed Lasik eye surgery; the first of which was performed in the United States in 1991. Lasik stands for Laser-Assisted In Situ Keratomileusis and makes correction to the cornea to improve light refraction. During Lasik eye surgery, the patient is first given numbing drops to anesthetize the eye. The patient lies down and the eye is held open with a speculum and immobilized with a cornea suction ring. The surgeon then cuts a thin flap into the top layer of the cornea. The flap is folded back to reveal the underlayer of the cornea ? the stroma. Using low-powered laser technology, the surgeon then resurfaces the stroma to improve light refraction. When the procedure is completed ? normally in less than 10 minutes ? the flap is replaced over the cornea and allowed to heal naturally.

Most patients report virtually no pain during Lasik eye surgery and only mild and infrequent discomfort. Recovery time is short; patients can generally resume normal activities ? with a few safety guidelines ? the day following the procedure.
