Fundamental of LASIK Eye Surgery is an article which can provide people an overall process of LASIK Eye Surgery. It is also a kind of medical treatment of eyes to eliminate the errors of patient which is related with their vision that may be myopia, hyperopia or astigmatism. LASIK stands for Laser Assisted In Situ Keratomileusis. LASIK Eye Surgery is not for every problem of eye but only for the vision problem like for the farsightedness or nearsightedness that means the people who are not able to see the clear image of distant object they will be able to see them clear and the people who are not able to see the clear image of close to object they will be able to see them clear.

Cause of vision problem:-

 As a fact, the ability of vision of an individual depends on her or his cornea which focuses the light on the retina of eye to structure the figure of any object.  It works exactly like a camera. When the shape of cornea gets little flawed due to gathering of many dead tissues over the cornea of eye, it causes the defect in the focusing ability of eye. To cover these fault the people used glasses and contact lenses but  some people thought that these decreases the value of their face and want to get released form these. For them LASIK Eye Surgery is a convenient substitute to take their specs and lenses away from their eyes.        

Procedure of LASIK Eye Surgery:-

 As above clarify that during this surgery the surgeons take out the dead tissues that assembles on the cornea of patient’s eye. Usually the surgeons use laser rays to remove these, devoid of disturbing the neighboring cells of the eye.  LASIK Eye Surgery is almost painless and faster than any other eye surgeries procedure because the surgeons make use of painkiller drops to numb the eye of the patient. The patients who are getting operated with LASIK Eye Surgery they gain much improvement in their vision just within sometime of surgery. 

For minimum risks and complications:-

Unlike any other surgeries, LASIK Eye Surgery also contains some risks and complications too. So it is important for patient that they choose a well qualified and experienced surgeon for LASIK Eye Surgery and before you deciding for LASIK Eye Surgery consult with the surgeons or your family doctor to get aware with all the risk factors of LASIK Eye Surgery.    

anonymous asked:


The most commonly used refractive surgery procedure is the lasik eye surgery procedure and this is a very popular form of surgery that has the advantage of being less painful and resulting in a 20/20 vision in most cases, usually on the very next day.

The basic lasik surgery procedure involves an instrument which is known as a microkeratome which is used in the surgery to create a thin and round flap in the cornea. The surgeon will take the flap and fold it back so that it is not in the way and then takes away some corneal tissue that is underneath with the help of an excimer laser which uses cool ultraviolet light beams to exactly remove very small bits of tissue from the cornea in order to reform it.

Once the cornea is reformed into the correct shape it will work in an improved manner and focuses light into the eye as also onto the retina thereby getting the person to see clearly which will be better than what it was before the lasik eye procedure. Afterwards, the flap is replaced back in place and covers the area where the corneal tissue had been removed.

Corrects Nearsightedness, Farsightedness as well as Astigmatism

Lasik surgery procedure is helpful for nearsighted as well as farsighted people. In the case of nearsightedness the aim is to flatten the extra-steep cornea and with farsightedness, a steeper cornea is required. Excimer lasers are also used to rectify astigmatism through smoothening of the irregular cornea and getting it into a more normal shape and the lasik eye procedure will help to achieve this.

There are certain steps to follow before getting your lasik eye procedure performed and these include choosing a good surgeon, finding out whether you are the right person for this type of surgery as well as finding out whether you have any dry eye diseases which need to be treated and cleared prior to the lasik eye procedure.

There are different types of lasik eye procedures such as blade versus bladeless and also custom lasik or wavefront lasik procedures. The wavefront-guided lasik eye surgery procedure makes use of 3-dimensional measurements that figures out how the eye processes images and this is helpful for guiding the laser in reshaping the front portion of the eye that is called the cornea. The wavefront measurement of the lasik eye surgery procedure is extremely useful in extreme and precise individualized vision correction.

Kevin Pederson asked:


Lasik Eye surgery is a surgical process that is aimed at reducing a person’s dependency on glasses or contact lenses. The article provides basic information on LASIK eye surgery.

LASIK (Laser-Assisted In Situ Keratomileusis) surgery permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A flap in the cornea is cut using an special knife called microkeratome. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middlesection of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. This is just one of the techniques of Lasik.

Lasik Eye Surgery: Is this the right time? Examine your eyes with your eye doctor to start with. You must be in good general health and should be over 18 years of age. You should not have any eye diseases of concern like cataracts or glaucoma. Laser vision correction can treat a very broad range of nearsightedness, farsightedness and astigmatism.

Does the Lasik eye surgery hurt? Is it painful? The surgery may be a bit uncomfortable for a few patients. One good way to learn more about how it might feel is to talk to someone who has had the procedure, such as a friend or relative, or a staff member at the doctor’s office. Most of the times, its just the fear of the unknown. Anesthetic drops are used to numb the eye just before surgery begins and you may be given a mild sedative. After your procedure, your eye may feel a foreign body sensation or irritation for a few hours, but most patients are quite comfortable after taking a short nap. You will be given drops for your eyes to counteract the potential dryness you may experience for several days following the surgery.

Recovery period after Lasik 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.

What are the risks from Lasik surgery? There are very few risks with the laser vision correction procedure. However, the chances of having a vision reducing complication have been documented in a number of clinical studies to be minimal. Do not forget that millions of people have had excellent results from laser vision correction.

J. Lloyd asked:


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.

April Kerr asked:

Everywhere you look there seems to be ads for LASIK eye surgery. The way they advertise the procedure can make you think that is will be the perfect solution to your vision problems. No more straining to read the ingredients on food packets or road signs. Simply undergo LASIK surgery and all there hassles will be a thing of the past.

However it is important to note that LASIK eye surgery may not be suitable for everyone so it’s important to read up as much as possible out the procedure.

The acronym LASIK means laser in-situ keratomy, eye surgery and uses an excimer which is a powerful laser. These have been specially designed to work on the delicate eye area. The laser can quickly re-shape the cornea (for treating nearsightedness) or the hyperopia (for treating farsightedness).

When the cornea is reshaped what happens is that tissue underneath is removed. So that the tissue can be worked on, a very small flap is pulled back from the surface of the cornea. The laser or microkeratome blade can be used to create this flap.

The laser zaps away excess tissue determined by the ophthalmologist whilst viewing an extremely detailed image of the cornea. This process can take only a matter of minutes and the patient won’t feel a thing. Vision can be corrected so swiftly that they are able to drive home aftwards.

The primary consideration when deciding if LASIK is for you is to look at the costs involved. Many health plans don’t cover this procedure as they believe it to be purely cosmetic.

The cost of surgery can vary greatly however the costs generally reflect the use of a reliable and experienced ophthalmologist and will cost several thousand dollars per eye. The cost is certainly not insignificant.

Cost isn’t the only consideration however. You can only undergo surgery if you have healthy eyes which have stopped changing. Other situations can also arise which prevent surgery.

When you go for your first consultation a number of tests will be performed to detect eye problems or diseases which could cause problems with the surgery. Because of hormones, LASIK surgery cannot be performed on pregnant women or on people with suppressed immune systems.

If you have the money to spend on surgery then LASIK may be a good way to improve your vision. The success rate is very high and the procedure is painless. There aren’t many reasons not to go ahead with treatment.

Louis Zhang asked:


LASIK eye surgery is a procedure that treats nearsightedness, farsightedness and astigmatism. LASIK stands for Laser-Assisted In Situ Keratomileusis.

A laser or a surgical blade is used to cut a flap in the cornea. Then, a laser removes tissue beneath the flap, permanently changing the focusing power of the cornea, thereby improving vision.

Laser eye surgery is relatively painless, quick and convenient. There are two surgical methods from which to choose.

Do your research, ask lots of questions and follow all of the surgeon’s directives both prior to and following the lasik procedure to improve its effectiveness.

The Lasik Procedure In order to access the stroma, the surgeon cuts a flap in the upper portion of the cornea, right above the pupil. Numbing drops are put into the eye, the cornea is marked to aid in replacing the flap, and then the eye area is cleaned.

A lid speculum holds the eye open. High pressure is applied to the eye with a suction ring that is briefly placed directly on the eye. Then the flap is cut. This is called a keratectomy, which may be done by either of two methods.

The time-tested way uses a microkeratome, a cutting instrument or blade. The newer method of cutting the flap is by “laser-only” or femtosecond lasik, sometimes known by the brand name “IntraLase”.

After the suction ring is removed, both lasik methods are nearly identical.

The corneal flap is folded back, and the exposed tissue is allowed to dry. Then, the patient is asked to stare at a light for about sixty seconds to help keep the eye fixed and immobile.

In less than one minute, the lasik computer pulses high-energy ultraviolet light removing the tissue that was previously determined to reshape the cornea most effectively and accurately.

The lasik laser makes clicking sounds, and there may be a smell of burning tissue. After very precise amounts of tissue are removed from the stroma, the surgeon lays the flap back into place. The eye is observed for a few minutes to make sure that proper bonding is taking place.

After Lasik Eye Surgery Once the surgery is complete, a protective shield is placed over the eye, to prevent pressure and anything from bumping the eye. Since there are no stitches in lasik surgery, these precautions must be taken to ensure that the flap remains in place.

Some patients return to work the next day, but most doctors recommend that you wait a few days. Strenuous activity, and non-contact sports should be avoided for up to three days.

Facial products and makeup are out for up to two weeks. The eyelashes may need to be scrubbed fairly often during this time to help prevent infection.

No contact sports are allowed for at least four weeks. Expect to leave off swimming, hot tubs, whirlpools and saunas for up to eight weeks.

Expected Outcomes from Lasik Most lasik patients see huge improvements in their vision by the next day. Vision may continue to improve for three to six months post-operatively. While visual fluctuations may occur temporarily throughout the day, this tendency diminishes over time.

Lasik eye surgery is not for everyone. Most good candidates follow their surgeon’s pre and post-operative directives faithfully. They find their vision, and therefore their lifestyle, greatly enhanced by this laser procedure.

Arvind asked:


Lasik that stands for Laser-Assisted In Situ Keratomileusis. It is a refractory laser eye surgery in which the deformities in the cornea of the eyes are corrected with mild laser rays. This procedure is approved by FDA and has a high rate of success that is around 92% to 95%. If compared with other forms of corrective eye surgeries, Lasik procedure takes less time, causes less pain and the recovery time in Lasik operation is also minimum. With a Lasik vision correction the common disorders of vision the myopia (nearsightedness), hyperopia (farsightedness), and astigmatism can be cured permanently. So, with a Lasik eye surgery New York you can get rid of those corrective glasses or contact lenses that you have to wear to get proper vision.

In Lasik operation the eyes are numbed, held with a speculum and then immobilized with a corneal suction ring. The surgeon cuts a small incision of the top layer of the cornea with a mechanical microkeratome using a metal blade or a femtosecond laser microkeratome to make a flap. The flap is then folded and the surgeon uses a low power excimer laser to resurface the stroma so that light is refracted correctly within the eye, while going forward. The process requires optimum precision and promptness of the surgeon for maximum benefit of the patient. So, it is important that you find one reputed Lasik eye institute that have the proper infrastructure and competent doctors to carry out the procedure. If you have chosen Lasik eye surgery New York to do the operation you are never short of options.

Not only Lasik eye surgery New York but you will also find number of Lasik centres throughout the country. In fact Lasik surgery Chicago can also be an option for you. You have to make the choice of Lasik centre based on some factors. It always better to choose a local centre, cost is another factor and of course quality of service remains the first priority.

Whatever Lasik eye surgery New York clinic you choose, make sure you are absolutely ready to undergo a Lasik surgery. Consult your eye surgeon and try to understand the complications of the Lasik surgery. It is wise to opt for the Lasik surgery only when you have a stable vision and didn’t require a change in the prescription for the glasses or contact lens during the last one year.

Chris Crowe asked:


Wavefront Lasik is called by some a slightly better procedure than the traditional lasik eye surgery operation. Also called custom wavefront lasik, this procedure is more precise than other procedures

because it maps corneal irregularities before the surgery begins.

This means that the wavefront lasik procedure (which is also more expensive) is more attuned to the actual eye it is being performed on. With a detailed map of the specific eye, in theory the procedure can be more effective in solving the particular vision deficiencies of the patient.

Traditional lasik utilizes a similar way of measuring the eye as when you get fitted for contacts or glasses. For people with minor vision modifications needed, this is fine. But for people with higher order aberrations, they may need a more exact procedure.

Nearsightedness, farsightedness, and astigmatism are some of these lower level problems that the normal lasik eye surgery may be used with great effect on. Other problems may require more specialization.

Wavefront lasik eye surgery works in a few steps. First, the doctor shines a light into the eye. A computer inputs the data (which will show any abnormalities in the eye) and analyzes the data. Then a three dimensional model of the eye is created and the laser is put to use.

A beam of laser light then shapes the inside layers of your cornea to replicate the particular prescription the patient has in glasses or contacts. In addition, it looks for other repairs that can be made to the eye to improve vision. Wavefront uses more technology–the name is derived from the fact that light waves are used to scan the eye and gather information about the cornea and any necessary vision corrections. Some people have had great outcomes with this surgery.

Some people have trouble with glasses and contacts and just can’t seem to avoid annoying vision problems like glare and the halo-effect of lights at night when they wear glasses. People who just don’t want to deal with glasses and contact lenses also may opt for lasik surgery. It’s very important to talk to qualified physicians about the procedure and be guided by them throughout.

The wavefront lasik procedure can take as little as a half-hour or even shorter, depending on the vision doctor and whatever guidelines he or she follows.

Since the corneal flap that is created is so tiny and is in a high-blood area of the face (the eye) recovery time is very quick. Most doctors recommend lots of fluids and that the patient avoids any kind of eye-straining activities. Reading and even watching television may be considered “too much.”

But even then, the healing process takes only two or three days. Lasik is a procedure that shouldn’t be taken lightly even though the process and the healing seems so quick, relatively painless, and easy. It is always necessary to find a vision specialist you trust and to find advice from people who have undergone the procedure, general basic information about the procedure, and any other information you can find to prepare yourself.

If you are not convinced that one doctor is right, you can always consult others to get a different perspective on your health needs. You only have one pair of eyes–you should take care of them.

John Porter asked:


Lasik eye surgery has gained tremendous popularity since the time it was introduced in the last decade. The main reasons for this has been its efficacy and the realtivly high rate of success compared to most other operations. But at the end of the day it is a question of your eyes and it is always better to be properly educated about the operation and the kind of complications you might face.

It is generally your optometrist who will first provide you with the details of the operation. In this article we just provide you an overview.

This eye surgery is used to cure three main types of eye conditions-myopia, hyperopia and astigmatism. Myopia, also know as nearsightedness is the problem of not being able to see what is far away without glasses. Hyperopia, also known as farsightedness, is the other way round. Astigmatism is something different where the patient has irregularities in his cornea which as a result distorts the image formed on the retina of the eye. The complications that one can face after surgery are discussed below.

The capacity to distinguish an item from its neighboring backdrop is a problem of contrast sensitivity. The reduction in contrast sensitivity is a comparatively common occurrence after LASIK surgery, particularly in patients with high amounts of myopia.

The occurrence of a second, generally fainter, image of an object next to the original object, creating an indistinct vision is what double vision or ghosting is. This problem is generally an effect of irregular astigmatism brought on by surgery. Like several other lasik-related vision problems, double vision often goes away over a period of time.

Then there is the problem of halos where one can see halos around lights. It must be noted that corneal swelling after this operation can cause halos for the first few weeks. In fact it is quite normal. However, if you think that the halo has persisted over a normal period of time, then it might be necessary for you to go for treatment again.

Another eye surgery related complication, starbursts cause a person to see lights as blurred. Often spikes or rays of light seem to radiate out of the center of the light source. Generally it affects night time vision, but in some cases, it might be a problem for all light sources at any time of the day.

Lasik has become a wildly popular surgery and while it does have some risks and occasional complications, it usually results in greatly improved vision for many people. To have the best chance for a successful recovery be aware of the restrictions after eye surgery. Here are the most important:

Prior to your lasik procedure, your eye care professional will have already performed an in-depth eye exam. In addition to an eye exam, you doctor needs a thorough health history to determine whether or not you are a good candidate for this procedure.

Many factors can make or break your eye surgery. To have the expected outcome, you must be a good candidate, you should follow all pre-operative instructions and you should always follow the post-operative instructions.

When you are ready for your operation procedure, your doctor will discuss several things to look for after surgery. He or she will also give you detailed post-operative instructions. Some of these restrictions may include not driving or working for several days, going to your check up appointments when scheduled, avoiding make up or touching the eye and refraining from physical activity.

J. Lloyd asked:


For anyone considering Lasik eye surgery, the importance of finding a reputable and experienced Lasik eye surgery center is absolutely crucial. Just as you would never embark on a surgical procedure with doctors that you didn’t know or trust, you should never entrust the health of your eyesight to random surgeons you find in the yellow pages of the phone book.

In order to get what you need from Lasik surgery – in a safe and effective way – you must find a surgical center that extends quality, dependability, experience, and professionalism to their patients – at all times.

Lasik eye surgery – for the uninitiated – is a refractive procedure that works to correct the way in which our eyes refract light. When light is captured by the lens of our eye – the portion of the eye located directly behind the iris, or colored part of the eye – the lens refracts, or bends, the light to be then captured by the retina, a group of cells in the lining in the back of the eye.

The retina then takes those light signals and converts them into messages that can be understood by the optic nerve in our brain. When there are refractive difficulties in our eyes – through nearsightedness, farsightedness, or astigmatism – the light is not refracted to the retina properly and the brain receives a message of a blurry image.

During the Lasik procedure, a laser is used to resurface the cornea – the thin, transparent covering that blankets the iris and lens of the eye – thus clearing the way for refractive clarity. Lasik is generally a painless procedure that can be performed in mere minutes. Skilled surgeons who work within a Lasik eye surgery center and perform this procedure on a daily basis are in the best position to assess your candidacy for the procedure and what will work best for your eyesight.

Begin your search for a Lasik eye surgery center by looking in your immediate area; logistical convenience should be your first consideration but it shouldn’t be your only one. Speak to people who have had the procedure performed in your area in order to get a sense for the more popular and reputable surgery centers.

If you are interested in a particular Lasik eye surgery center, then speak to patients who have had the procedure performed in that center and who are willing to share their experience. Finally, visit the centers in which you are interested to assess their organization, patient care including pre-operative and post-operative care, cleanliness, professionalism of the staff, and financial options available to you.

Once you have decided on a Lasik eye surgery center it is important to then research the surgeons who work within the center and who will be assigned to your case. With the assistance of the Internet it does not take very long to investigate the education, experience, and reputation of any surgeon in which you are interested. Meet with the surgeon yourself to get a feel for his/her standard of care and what systems they put into place to ensure your comfort and successful outcome.
