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 For Perfect Eye Sight
If you have ever worn glasses or contacts you have probably considered the benefits of Lasik eye surgery. Here we will look at what this surgery consists of and how it may be beneficial to you.
Lasik was developed around 1990 as a modification and blending of two other procedures that had been around since the 50′s. It is the process of using laser equipment to make a small flap that is pulled back, allowing access to the tissue below for reshaping by the laser.
The surgery has been successful in treating a range of vision problems. It has been found effective on patients with myopia, hyperopic and astigmatism.
PRE-OP
The procedure itself is quick and painless. If you wear soft contacts, it is suggested that you remove them for a minimum of 5-21 days before the surgery. For hard contact patients the requirements are a bit stiffer. Hard contact wearers should remove their contacts for six weeks before the surgery and an additional six weeks for every three years they have had them.
POST-OP
Once the surgery is complete, the patient will be prescribed a round of mild antibiotics and anti-inflammatory eye drops. In addition, you should get plenty of sleep and wear both darkened sunglasses during the day and goggles to prevent rubbing your eyes at night. This will decrease the chances for postoperative complications.
OUTCOME
The results have been most adequately calculated by patient satisfaction. In 2008, the American Society of Cataract and Refractive Surgery did an analysis on worldwide patient satisfaction over the past ten years and found that 95.4% were very satisfied with the outcome.
RISKS
As with any surgery, there are of course risks to consider. Below is a list of possible problems after Lasik surgery.
- Dry eyes: This is the most common complaint after Lasik surgery. It occurs because nerve endings in the cornea are responsible for tear production. Many times this side effect will go away several weeks after surgery, but in some cases, it may be permanent.
- Overcorrection or under correction
- Visual acuity fluctuation
- Light sensitivity
- Ghost images or double vision
These are a few of the more common side effects of Lasik surgery. A proper preoperative examination is crucial to minimizing these risks.
COST
The cost of Lasik will vary depending on provider and the condition of your eyes. The more complicated the surgery and follow up the more expensive it will be.
That being said a recent study of 2008 costs estimate the range to be between $1,000 and $3,000 per eye. Beware of advertisements that offer Lasik for as little as $500 per eye, there are often strict guidelines for this cheap alternative that most people will not fall into. These offers often come with a necessary deposit, which is non-refundable if you opt to not have the surgery.
CONCLUSION
Lasik eye surgery is a great option for some people. As technology increases the procedures become better and better. However, the advice is to seek out all the possible side effects and be sure that you could live with them. The incidence of problems is small, less than 5% of Lasik patients have any complaints but it is better to be safe than sorry.
How Safe Is Lasik Eye Surgery In The Elderly Years ?
It’s a pretty well-established fact that most people experience a decline in the quality of their vision when they hit their forties. And, with a very large population of baby boomers now in their forties and above, the demand for corrective eye surgery to help improve these common vision problems has been on the rise. But many senior citizens question if it is worth it to have Lasik eye surgery in their later years.
The answer, according to experienced ophthalmologists and laser eye surgeons, is that people are eligible for laser eye surgery at just about any stage of life. Those experiencing problems with their eyesight can enjoy improvement with correction laser vision surgery. The main vision problems that can be improved with corrective eye surgery are astigmatism, far-sightedness and near-sightedness.
Lasik eye surgery in virtually any stage of life is considered a very low risk procedure, overall. But, there are a few precautions that doctors recommend to those who are a bit older. One common condition that the elderly deal with is eye dryness and therefore, after Lasik eye surgery, the elderly are strongly encouraged to take extra care to be sure to keep the eyes well-hydrated and lubricated with eye drops.
Lubrication of the eyes after Lasik eye surgery is not only important for those who are having the procedure done in their later years. Keeping the eyes moist and keeping them from drying out is an important part of aftercare for everyone who has undergone corrective eye surgery, but it is even more crucial for the elderly and for anyone who tends to naturally have dry eyes.
Using eyedrops routinely after the corrective procedure is a very simple, yet very effective way to avoid problems and complications. The laser eye surgery clinic will provide the patient with the proper lubricating eye drops for post-surgery use.
One of the reasons why eye surgery in the later years is still safe and effective is because overall the procedure has proven to have very few complications and has very low risk. This is because the surface of the eye is not cut with traditional surgical instruments, which can cause damage to the cornea.
Instead, the small cut that needs to be made is accomplished with a laser beam. This means the incision will be tiny, accurate and extremely clean. All of these factors result in much less risk of infection and other complications.
However, even with a very good track record of success, eye surgery in general is not completely foolproof. Corrective eye surgery patients experience complications from the procedure or disappointing results approximately 5% of the time. When the procedure does not go well, the patient might end up having fluctuating vision, seeing halos around light sources, having increased sensitivity to glaring light, and possibly experiencing more dryness of the eyes.
Even though most laser eye surgeons are in agreement that Lasik eye surgery in the later stages of life is still a viable and effective option, they also mention that Lasik vision surgery is not the right procedure for everyone. There are conditions, such as glaucoma and presbyopia, which will not be corrected through laser eye surgery. In fact, with glaucoma, such a procedure can even worsen the condition.
5 Tips for Post Treatment Lasik Eye Surgery
Lasik eye surgery has performed by the eye surgeon to the patients who are suffering from the various diseases like myopia, hyperopia and astigmatism.
The lasik surgery can cure all the problems and improve the vision.
1. People normally perform the lasik surgery needs extra care after the surgery. People who performed the lasik surgery and needs special care and wear lenses or glasses for extra care.
2. The doctor given the eye drop to protect the eyes, you must have to put the drop at regularly. The after care treatment is more important. It will take time to correct the eyes.
3. The post operative position is essential in the lasik eye surgery to take care of the eyes. The lasik surgery needs few weeks and it requires treatments properly to take extra care in the post operative position. Once the lasik surgery performs than the post treatment anti-inflammatory and anti-biotic medicine are used for the treatments.
4. Post operative eye care is one of the essential tasks to take care of eyes. You must have to follow the guidelines like you must have to wear the dark glasses and follow the strict instructions given by the eye surgeon. It is essential to keep the proper treatment to give better care of the eyes.
5. You must have to take care of your eyes and avoid any types of infections till the healing of eyes. It is essential to avoid such types of complications. It is better you can strictly follow the guidelines under post operative condition.
Lasik Eye Surgery – A Refractive Eye Surgical Procedure
Lasik eye surgery is a refractive surgical procedure that works wonders on the eyes of people suffering from nearsightedness, farsightedness, astigmatism and presbyopia. It reduces a person’s complete dependency on glasses and contact lenses. The full form of Lasik is Laser-Assisted In Situ Keratomileusis and is a procedure that involves permanently changing the shape of the cornea, the clear covering of the front of the eye using an excimer laser.
How is Lasik surgery done?
The surgery should be done with great skill as it involves the most delicate part of human body. It is done with a knife called microkeratome and is used to cut a flap in the cornea. A hinge is done at one end of this flap and then the flap is folded back revealing the stroma, which is the middle section of the cornea. Instant pulses from a computer-controlled laser vaporize a portion of the stroma and the flap can be easily replaced.
How is Lasik advantageous over other surgical procedures?
Lasik eye surgery is quite advantageous over other surgery procedures because they often involve much less pain as an aftermath. Lasik unlike other eye surgeries also promise extremely good vision that can be achieved almost immediately or at least by the next day.
What to do in Lasik eye surgery?
But before you go for the Lasik surgery, you should have a proper test done by your physician. The optician will examine your eyes to determine their health, analyze the kind of visual correction needed and determine how much Lasik ablation is required. Risks like losing vision, developing debilitating visual symptoms, severe dry eye and large refractive errors are often associated with Lasik eye surgeries. So you consult a proper eye surgeon for the best results.
Once you are confident about undergoing the Lasik eye surgery you should follow certain rules to get quick results from the surgery. Following is a brief history of what should be done before, during and after Lasik:
Before surgery
§ Stop wearing soft contact lenses, rigid gas permeable lenses and hard lenses. § Do not feel pressurized by your doctor, friends and family § Stop using creams, lotions, perfumes and make-ups. § Keep removing all debris and residues from the eye surfaces.
During surgery
§ Apply a numbing drop to your eye that will clean the area around your eye and create a numb feeling near your eyes. § Wear the shield that holds the flaps in places. Wear it to prevent any sudden accidents or getting hit in your eyes.
After surgery
§ Consult your doctor immediately in case of any itching, eye irritation, mild pain or sudden discomfort. § Use eye drops given by the doctor to prevent infections or inflammations. § Never wear contact lenses at least for next fortnight.
Lasik eye surgery is hassle-free but you should take proper care for your eyes. In spite of such care, if you face any worsening symptoms you should immediately contact your doctor to prevent any further eye-related problems.
Lasik Eye Surgery Procedure – Extremely Precise Vision Correction

Filed under Non Fiction
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.
Lasik Eye Surgery – A Boon For Everyone
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.
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.
