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.

Lasik Eye Surgery Exposed
Lasik eye surgery stands for Laser Assisted In-Situ Keratomileusis. It actually reduces people’s dependence on their glasses or contact lenses and involves a simple short surgical procedure on your eye using a cool laser beam. The whole procedure is virtually painless, takes only minutes per eye and is a one day procedure so you may go home the next day.
The Lasik procedure is as simple as the following three easy steps.
1. The cornea is like a few layers of stacked paper. An instrument
called a microkeratome gently glides across the top two of these
layers creating a flap which has like a hinge.
2. The doctor then has access to the third layer or the stroma of your
eye. The Excimer Laser then alters the shape of the cornea by the effect it has on the stroma.
3. The flap is then repositioned back over the newly contoured stroma without the need for stitches as eye tissue binds together
very quickly and simply on its own.
After this simple process, you are then sent home to rest. You will feel a
little discomfort, rather like having an eye lash stuck in your eye for about 12 hours or so until the healing process is well under way.
On average, one in 5 people are not suitable for Lasik surgery and this
can only be determined by a professional. Those not deemed suitable for Lasik may be more suited to other types of surgery so it is important to be aware of your options.
One of the best parts about Lasik eye surgery is that by the next day, your vision will have improved to the point where you can at least drive a car. Many people report their eyesight having improved to 20/20 vision!
The end result hopefully of Lasik surgery is to return the cornea to as close to a normal shape as possible, and in doing so improve your vision. Although Lasik surgery appears to produce what seem to be miraculous cures, it is also possible that complications may be included in the end result.
For those in the forty plus bracket who decide to try Lasik surgery, they may discover that they still require eyeglasses for reading. If you are thinking about Lasik eye surgery, you would be well advised to do thorough research, gather all the facts and get a solid understanding of what you should expect before committing to the procedure.
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.
The Truth About Complications From Lasik Eye Surgery
The risk of complications from lasik eye surgery definitely exist but in reality, they are only minimal.
Obviously, surgery is not suitable for everyone and if you are considering lasik, you are not automatically guaranteed going under the surgeon’s laser. The pre-screening period is vital in assessing your suitability as a candidate for surgery.
If you are experiencing certain problems which will place you at risk or increase your risk of becoming impaired in some form or another, then don’t be surprised if you are not approved.
Less than one per cent of patients have experienced serious complications arising from lasik eye surgery. This figure just proves that there is risk associated with any kind of operation and while it’s only slight with this procedure it’s there nevertheless and you you should be aware of it.
So what are some of the complications from lasik eye surgery you could be at risk from? Let’s take a look at just a few.
Flap Complications
Issues with the flap can make up about 5% of lasik complications. Basically, problems can arise when the flap is not properly re-shaped and could either be too thin or too thick. Ill-fitting flaps may wrinkle soo after being placed on the eye’s surface.
The good news is on most occasions, this can be corrected with follow up treatment. Can it affect your vision? Yes, but in the majority of cases, only temporarily.
Cornea Issues
Double vision can arise from issues such as bad laser correction which doesn’t center on the eye. The cornea can also react to foreign debris which is caught under the flap. Inflammation usually occurs and permanent vision loss is a risk however, this is a slight risk provided follow up treatment is conducted in quick time.
Some of the other more common complications of lasik eye surgery include dry eye along with over and under correction. The issue of regression, meaning the eye returns back to it’s former condition after a certain time, is also a possibility but this cannot really be predicted.
As with most of the complications mentioned, follow up treatment will in most cases rectify any issues and this treatment doesn’t have to be more surgery. It could simply be medication prescribed by your doctor.
You will place yourself at great risk if you are initially rejected as a lasik candidate and then attempt to get the procedure performed elsewhere. Sure, get a second opinion but a quality and responsible eye surgery center will not want to perform treatment on your eyes if it means putting you at risk.
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
May 10, 2011 by admin
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.
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!
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.
