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.
Lasik Eye Surgery Procedure – Extremely Precise Vision Correction

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.
Safety and Lasik Eye Surgery
Lasik eye surgery corrects blurry vision that occurs from a misshapen cornea. The cornea bends light rays to help them focus properly on the retina at the back of the eye. By cutting and lifting a small flap of tissue from the outside of the eyeball, a surgeon can use a laser to reshape the cornea before replacing the tissue, removing your need to wear corrective eyewear.
The procedure is done over two million times a year in the USA, with a very low rate of infection. Complications, like blurred vision, corneal scarring, dryness and haloes or starbursts around lights, generally occur in only 1% of cases and if your surgeon has performed over 1000 of these procedures, the risk is even less.
Lasik Eye Surgery Safety Tips
Lasik eye surgery is not a cure for any and all eye problems. Older patients often require reading glasses because of hardening of the lens, which can’t be corrected by laser surgery. The surgery also does not have a fantastic result for those with either very weak or very strong prescriptions for glasses or contact lenses. Being informed about your eligibility for the surgery will ultimately help you avoid disappointment and an unfavourable result.
Surgeons who offer you a “20/20 Vision Guarantee!” should most certainly be avoided. Many Lasik eye surgeries actually require a 3 month follow up and should not be taken lightly, by you or the surgeon. Only registered Ophthalmologists are permitted, and are qualified and experienced enough, to perform the procedure. So ensure that you choose your laser-wielding doctor wisely!
Lasik eye surgery does run the risk of a slight loss of vision and diminished night or fog vision that can’t be corrected by glasses or contact lenses. While a low risk, ensure that you discuss your options with the surgeon and that the benefits outweigh these risks.
Lasik eye surgery is a relatively safe procedure, with amazing benefits accompanying minimal risks. In order to have a positive experience, ensure that you’re well-informed and make educated choices, then simply enjoy your new clear vision!
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.
Leave your Apprehensions Behind With Lasik Eye Surgery Center
It has become easier to get treated for any disease easily these days, all thanks to the advent of information technology along with the advancement of medical science. However, getting operated for some treatment leaves people with many apprehensions, especially when the vital organs like eyes are in question. Sometimes, even looking for lasik eye surgery center becomes tough, but not any more, as you can flip through the pages of the directories or even get information through search engines.
The doctors at the lasik eye surgery center will offer you treatment for eye diseases and conditions like myopia – a condition in which things that are at quite a distance, become blurred or indistinct, but things that are approachable can be viewed easily and clearly. The other condition, hyperopia is characterized by clear vision when viewing objects in the distance but blurrs vision up close. Lasik surgery is also effective for astigmatism, which is a distortion of the image as reflected on the retina. This is caused by a misshapen cornea or lens of the eye. In fact, the combination of these conditions is common and can be cured easily at any good and reliable lasik eye surgery center.
Well informed doctors from the center will provide you with the information on the procedure of lasik surgery. In fact, if anyone who wishes to undergo the lasik surgery wears contact lenses, then it is advisable to stop wearing them before the initial check-up. The center will ask to you not to wear contact lenses for at least two weeks before surgery, as they are capable of altering the shape of the cornea. The doctors from the center can choose a treatment from a variety of procedures that suit the eye condition. However, wavefront mapping method is generally used prior to the surgery. Lasik treatment is not advisable for pregnant or nursing women or people with various conditions like corneal scratching or infection, keratonconus, herpes simplex or herpes zoster, glaucoma or high blood pressure, inflammation of the eye or eyelid and crusting of the eyelashes. In fact, a consultant from lasik eye surgery center will further inform you on the conditions that cannot be treated or are less likely to be successful.
In fact, the consultants from lasik eye surgery center will also advise you to restrain from using the cosmetics, at least a day before the surgery. This is to prevent debris from entering the eyes that can cause incorrect incisions and lead to infections. A reliable lasik eye surgery center also imparts information on the recovery period and risks involved. The vision may take three to eight weeks to stabilize. If you suffered from any visual problems before your surgery other than distance viewing conditions, it is important to remember that the surgery is not expected to correct any of those conditions that were pre-existing. While lasik eye surgery is quite safe, there is always the slight risk of complication. Hence, it is important to consider these risks before going for or deciding on the procedure. And that is what the lasik eye surgery center does, by giving you factual points involved in the lasik surgery.
Alternatives to Lasik Eye Surgery if You’re a Less Than Ideal Candidate
LASIK eye surgery is elective. It is not cosmetic, like facelifts, or medically necessary, like heart bypasses, but it does correct a physical problem and enhance quality of life. However, if you are comfortable wearing glasses or contact lenses, you don’t really have to have any kind of laser eye surgery.
There are a number of reasons why you might not be an ideal candidate for LASIK eye surgery. Not all LASIK surgery alternatives involve the same degree of surgical intervention. For example, intracameral intraocular lenses (ICLs), which are pending approval by the FDA, may become a good option if you are simply too nearsighted or farsighted to benefit from LASIK. A small lens is placed behind the pupil but just in front of the eye’s existing lens, adding another focusing apparatus and changing the orb’s focal point. When approved, this procedure could become quite popular, but probably won’t replace LASIK because of the additional risk.
There are several types of intraocular lenses (IOLs) that can be implanted in the eye, temporarily or permanently, to correct moderate to severe nearsightedness. In nearsighted patients, light rays focus in front of the retina resulting in blurry vision, so the IOL is placed behind the cornea to alter the focus and improve vision. Like LASIK surgery, this is an outpatient procedure than takes little time.
There are several different laser surgery methods available as alternatives if you are not a good candidate for LASIK eye surgery. One of the best known, and most widely performed, is photorefractive keratectomy (PRK), which uses a laser to sculpt the cornea’s exterior surface. (LASIK makes changes inside the cornea.) For patients with low to moderate nearsightedness and farsightedness, with or without astigmatism, PRK has proven extremely beneficial. This procedure is often recommended if you have certain corneal conditions, such as ulcerated areas, scarring, or what is called “recurrent corneal erosion.” It takes longer to achieve a final result from a PRK surgery because there is a greater amount of tissue that requires healing.
A new procedure called laser epithelial keratomileusis (LASEK) – simply a modification of photorefractive keratectomy (PRK) – was developed by an Italian surgeon and first described in the medical literature in 1999. In the LASEK procedure the surgeon loosens the outer layer of the cornea (epithelium); but, unlike PRK, the epithelium is not removed but folded back so the laser can sculpt the cornea as it is exposed. After applying the laser, the surgeon replaces the epithelium over the cornea. Vision recovery following LASEK is usually faster than with PRK, but slower than LASIK.
The LASEK procedure, which utilizes the eye surgeon’s favorite laser (called an “excimer” laser), is not FDA-approved. Surgeons cannot advertise the LASEK procedure except to get subjects for clinical trials. Early results with this procedure are promising, but many additional studies are required before LASEK is accepted as a safe, effective procedure.
Research continues on both surgical and non-invasive vision correction procedures. Using a variety of approaches, from implanting plastic pieces to reshape the cornea to using different heat sources than lasers (like radio waves and probes), doctors and physiologists continue to make progress in the treatment of various eye maladies. Somewhere among the many existing and soon-to-arrive techniques, from LASIK to LASEK, there is bound to be one that matches up well with your diagnosis, goals, expectations and comfort level.
What Complications You Can Face After A Lasik Eye Surgery

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.
The Importance Of A Reputable Lasik Eye Surgery Center
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.
