See Your Way To Lasik Laser Eye Surgery

Tuesday, May 23rd, 2006


Before you decide to have Lasik Laser Eye Surgery, you should do some research on both the type of surgery and the doctor who you want to perform it.


Electing to have corrective surgery on your eyes can be a great way to free yourself from the daily grind of constantly cleaning off and adjusting your glasses or cleaning contact lenses. This type of corrective surgery is quite common these days and considered safe. Before you decide to have this procedure, you should do some research on both the type of surgery and the doctor who you want to perform it.

Types Of Laser Eye Surgery: Before you pick your Lasik Laser Eye Surgery Newark location, you should look at the different types of procedures. Three type of surgery you may want to consider include:

• LASIK or Laser-Assisted In Situ Keratomileusis is the most well known. This surgery cuts a flap in the cornea and reshapes it by removing tissue. It is a fast procedure with healing in a day or 2 and immediate improvement in eyesight.

• PRK or Photo Refractive Keratectomy is the procedure that has been around the longest. Cells are removed from the cornea to reshape it and improve vision. It has a healing time of a month and vision improvement is not immediate but gradual over time.

• CK or Conductive Keratoplasty is a fairly new procedure. Uses radio frequency energy applied with a hair thin device to reshape the cornea. It is an extremely quick procedure with very quick healing.

Risks

Although most people are good candidates for corrective eye surgery, some should not undergo the treatment or it may seriously impair their vision. For this reason, you should discuss having the surgery at length with your doctor who should advise you of any risks and evaluate your situation to insure the surgery is safe for you. In rare cases your vision could become severely impaired, so it is important to get a thorough evaluation and disclose all health issues to your doctor. Other risks include fuzzy vision, irritation of dry eye syndrome and loss of clearness of vision.

Benefits

Being about to see without the aid of contacts or glasses is wonderful! Imagine waking up and being able to see beyond the end of your bed? There are many everyday benefits to having your vision restored. Without having glasses or contacts in the way, it is much easier to be active and play sports. Plus you’ll never have to worry about breaking or misplacing your glasses or contacts or incur the yearly expense for new prescriptions.

Obviously, you should take any procedure involving your eyes very seriously. Make sure you put a lot of consideration into the procedure and doctor you want to restore your vision.

Laser Eye Surgery - There Are Four Types

Monday, May 22nd, 2006



While it is true that LASIK Laser Eye Surgery is a type of laser eye surgery, there are a number of other laser procedures that can produce equally successful results.


When most people think of laser eye surgery, they automatically think of LASIK. While it is true that LASIK is a type of laser eye surgery, there are a number of other laser procedures that can produce equally successful results for individuals suffering from myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. In fact, there are actually four different types of laser eye surgery:

PRK, LASIK, Customized LASIK, and LASEK.  PRK, or photorefractive keratectomy, makes use of a specialized cool laser beam, called an excimer laser, to remove excess corneal tissue. The removal of this tissue corrects the shape of the eye so that light entering the eye can be properly focused on the retina. The outer surface layer called the epithelium, is removed to expose the underlying corneal tissue. Once this tissue is revealed, the excimer laser is used to reshape the cornea. The main distinction between PRK and LASIK is that PRK does not make use of a corneal flap. Instead, the epithelium is allowed to gradually heal through the body’s natural healing process. To protect the exposed cornea, surgeons fit patients with a lightweight contact lens to serve as a bandage for the eye. The contact lens also reduces discomfort. The lens is usually only worn for a few days, two to three days post-operative, at which time the eye is allowed to heal as normal with no bandage.
LASIK is the most widely known and performed type of laser eye surgery in the United States. LASIK stands for Laser Assisted In-Situ Keratomileusis, which literally means to “reshape the cornea from within using a laser.”

LASIK differs from PRK in that a small flap is made in the stroma of the eye. This flap, made by either a microkeratome or IntraLase, is then peeled back to expose the underlying corneal tissue. An excimer laser is then used to reshape the cornea to correct any refractive errors. Once the cornea has been reshaped, the cornea flap is put back into place and smoothed out. The flap acts as a natural bandage to help the eye heal and protect the delicate cornea. The benefit of LASIK is that the use of the flap helps the cornea heals more quickly than it would using the PRK technique, and reduces much of the discomfort felt during the healing process.

Many ophthalmologic surgeons are now offered the next evolution in LASIK surgery, which they called Customized LASIK. The general procedure used to correct refractive errors is the same as is used for traditional LASIK procedures, with the addition of wavefront devices used to map the unique surface of the patient’s eye. The wavefront device passes a narrow ray of light through the systems and into the eye, measuring any optical distortions that result as the light exits back out the eye. Any irregularities identified are then fed back into the system so that the laser can automatically correct for aberrations on the surface of the eye. Proponents of Customized LASIK claim that the use of wavefront technology enables surgeons to treat higher order aberrations that can contribute to low-light visual disturbances such as halos and glare not corrected by traditional LASIK, eyeglasses, or contact lenses. Customized LASIK can provide patients who suffer from higher order aberrations with an increase in visual clarity.

The final type of laser eye surgery is LASEK, or Laser Assisted Sub-Epithelial Keratectomy. LASEK is especially helpful for patients who have a thin or flat cornea, making them questionable candidates for LASIK and Customized LASIK procedures. During LASEK, a small trephine blade is used to cut into the outer skin of the eye, called the epithelium. Once the cut has been made, the eye is bathed in a mild alcohol solution to allow the edges of the epithelium to soften. This permits the surgeon to gently tease the epithelium flap out of the way to expose the underlying tissue. An excimer layer reshapes the eye under the flap to correct any refractive errors, after which the flap is replaced over the treated cornea. As with LASIK, the replacement of the flap in LASEK speeds up the natural healing process and serves to minimize discomfort resulting from the procedure.

Although the end result of PRK, LASIK, Customized LASIK, and LASEK is the same - the reduction of refractive errors - the method by which these corrections are made differ. Each procedure has its advantages and disadvantages and is best suited for certain types of patients. Individuals who are considering laser eye surgery to correct their vision and reduce dependency on corrective lenses are urged to contact their ophthalmologist to inquire about available options and learn if they are a strong candidate for one of more of these procedures.Gray Rollins is a featured writer for MyEyeSurgery.com.

Unsure About LASIK Eye Surgery? Epithelial Keratomiluesis Is One Alternaive to LASIK Laser Eye Surgery

Wednesday, May 17th, 2006




Unsure About Lasik Laser Eye Surgery? There Are Alternatives.

It’s true that lasik laser eye surgery is one of the most prevalent types of eye surgery. However, a few people are either not comfortable with, or not suitable for LASIK surgery due to inadequate thickness of the corneal tissue.There are several alternatives toLASIK eye surgery, each possessing certain characteristics that make it more appropriate in a particular situation. The procedures may bedifferent, but the key intent is to correct the vision. The following are a few of the major alternatives toLASIK laser eye surgery.

LASEK (Laser-Assisted Sub-Epithelial Keratomiluesis) is a recent addition to the refractive surgery catalog. As noted above, the density of the corneal tissue is inadequate in some patients, and hence, LASIK is not a possible option for them. In such a scenario, procedures like LASEK or PRK (Photo-Refractive Keratectomy) can be viable alternatives. These procedures produce the same results but require less tissue removal when compared with the LASIK procedure. That is, a thinner flap is cut in the corneal tissue.

Intraocular Lens Implant - In essence, this surgery is the same as cataract extraction with placement of a clear intraocular lens. The natural lens, the one having a refractive error, is extracted and replaced with a clear lens that provides clearer vision. This procedure is especially beneficial if the patient is suffering from hypermetropia (farsightedness) and that too with a high refractive error.

Spectacles or Contact Lenses - Glasses and contact lenses have been a popular choice for many years now. They are an affordable alternative to LASIK surgery. Spectacles or contact lenses are certainly a much safer proposition, since any sort of surgery has a potential for side effects and complications. There can be nothing as simple as wearing spectacles or contact lenses. With an elaborate series of new designs and makes, your spectacles can be strong fashion statement as well.

Don’t hastily jump on a conclusion. It is advised that you carefully examine all the above alternatives prior to going in for a surgery. Do your best to avoid any surgical treatment. If you suffer from a minor refractive error, one that can be easily corrected by wearing glasses or contact lenses, there is no point going in for a LASIK surgery.

Wavefront Lasik Eye Surgery - Better Than Conventional LASIK Eye Surgery?

Monday, May 15th, 2006


Traditional lasik laser eye surgery achieves a simple correction of focusing power by reshaping the cornea with the aid of a laser.Wavefront lasik eye surgery is a variation of that conventional procedure and accomplishes a spatially varying correction based on readings from a wavefront sensor. In essence, a wavefront sensor measures the eye itself. It detects any aberrations by directing a weak laser source into the eye, and by sampling and processing the reflection off the retina.

Wavefront lasik laser eye measurements reveal the irregularities of the lens, which cause optical aberrations (any deviation from a desired perfect planar wavefront). Wavefront custom sculpts the cornea to accomplish corrected vision. In many ways, Wavefront lasik laser eye surgery offers better results than traditional LASIK eye surgery. The procedure is carried out by an ophthalmologist, with the aid of sophisticated computer-controlled equipment.

Lasik has certain potential side effects including halos or glare, which are caused due to induced spherical aberration. Wavefront has helped reduce instances of such cases where patients complain of post-operative halos or glares. A drop in such complaints is owing to the precise measurements provided by the wavefront sensor. Thus Wavefront can help achieve a more optically perfect eye, since the corneal tissue area to be carved is measured more precisely using advanced technology and tools. But, wavefront aberrations are not the sole cause for all types of vision impairments. Therefore,Wavefront LASIK laser eye surgery should not be treated as a panacea for all kinds of vision defects. However, eye surgeons claim that a great deal of success has been accomplished in patient satisfaction, relative to earlier refractive surgery procedures.

Though wavefront technology has been used for years by astronomers who require adjusting their telescope optics, its application to human vision has been discovered only recently. It’s true that Wavefront is a superior procedure, but it’s certainly not required by or suitable for everyone. It is imperative that you go through an elaborate wavefront diagnostic to determine if you are a potential candidate for it.

Lasik Laser Eye Correction Surgery Safety

Saturday, May 13th, 2006




When it comes to eye impairments, there are many concerns. The eyes are one of the most sensitive parts of the body, which means that even a little, tiny mistake may put total vision at risk . With so many doubts, worries and frustration,
Lasik Laser Eye Correction Surgery appears to be the number one choice of thousands of people who have any sort of vision impairment. This is because of the safety involved in the procedure plus the benefits. What could please people more than combining safety with benefits?

This surgery is safe due to the unique type of laser used: the excimer. This special light was designed exclusively to be used in Lasik surgery, offering no risk to people who undergo the procedure. Lasik surgery is declared to be the best and the highest technology procedure to correct vision impairments.

Lasik Procedure

The Lasik procedure is really simple. It’s so simple that people who undergo this surgery are able to get back to work the next day. There is no need to stay at home and spend those boring days - as doctors like to say - recovering. The idea lies in the fact that all vision impairment has to do with irregularity around the cornea. Due to this, the procedure consists of cutting away the bad tissue surrounding the cornea and reshaping the cornea, which corrects your vision. The surgery is performed with the patient awake. However, the patient will be given some mild sedative in order to keep the body relaxed and anesthetic eye drops. The surgeon operates the laser and a computer system tracks 4000 times per second the patient’s eye position and simply redirects the laser pulses for precise placement.One day after undergoing the procedure, the person feels a significant improvement in the vision.

Lasik Complications

It’s not common, but Lasik surgery can have some complications. Although it is the safest and most technological method to correct vision impairments, some complications are not overruled.


The most common situations are:

- dry eyes

- over/undercorrection

- visual acuity fluctuation

- light sensitivity

- double vision

- decentered ablation

There are some others, but when complications happen, these are the most frequent.


Lasik Benefits

People sometimes are afraid to undergo Lasik surgery in order to correct their vision because, most of the time, they are not aware of what exactly the benefits are. Here, it’s important to make clear that although complications may occur, they are rare and the benefits are worth taking the risk. Besides, studies show that less than 5% of people who undergo this procedure experience complications. The most interesting benefits are:

- elimination of the need for glasses

- the discomfort felt with the use of lenses will be gone

- the quality of vision will be increased

- people will be able to pass a driver’s test without glasses.

How To Find The Best Eye Surgeons For Lasik Laser Eye Surgery

Saturday, May 13th, 2006

Visually challenged people fed up with not being able to see without the benefit of prescription lenses or contacts often turn to Lasik Laser Eye Surgery for an alternative. But, finding the best Lasik Surgeon should be an absolute priority. To find the best lasik laser eye surgery New York physicians can offer might take time, but it’s worth the effort.Before even beginning the search for a licensed eye surgeon to perform the procedure, the best thing to do is make sure you understand it. After that, decide if you truly want to pursue eye surgery and then begin looking for the best New York can provide.

Lasik Laser Eye Surgery work by correcting structural problems within the eye that create vision issues. Those with nearsightedness, farsightedness and even distorted vision can see some remarkable improvements if the procedure is done correctly and success is the outcome.
Lasik itself works by having the surgeon use a laser and a knife to reshape the cornea. This is the covering on the front of the eye. During the surgery, the cornea is opened to reveal the stroma. A portion of this part of the eye is vaporized to create the correct shaping for better vision and the cornea is replaced.

Although relatively painless with few complications, lasik laser eye surgery is a big deal. If a doctor isn’t as skilled as he or she should be, problems can result. Inasmuch, patients owe themselves and their vision the favor of making sure the best doctor is hired. And, even if everything is done correctly, problems can still arise. This is where a skilled, practiced surgeon can make a real difference.

Considering the number of eye surgeons touting their services much like car salespeople hawk their vehicles, it’s very hard for a patient to decide whom to turn to for this type of surgery. Going with the first lasik surgeon that’s spotted on a billboard or television commercial may not be the best idea. They can certainly be considered, but make sure that more than a friendly smile on the doctor is checked out before surgery commences. Those in New York looking for the best laser eye surgeon can start with the ads or even the phone book, but more work should be done. One a doctor or doctors have been selected, go visit them. Check into their background and even talk to past patients. A long track record in performing eye surgery successfully should be a must. If possible, even check with the state’s licensing boards to make sure no major complaints have been filed.

It may seem a little paranoid to check a lasik surgeon out like he or she is going for top government security clearance, but it’s eyesight we’re talking about here. Rely on trust alone for your plumber, maybe, but don’t do it for a medical professional. Take advantage of free consultations, speak at length with the doctor about the procedure, check backgrounds and them make a decision.

Since we’re talking about eyesight here and a genuine chance to improve it, it just doesn’t make sense to settle for less than the best. The smart consumers will not settle for anything less than the best when it comes to having lasik laser eye surgery. A little patience and some homework can absolutely net the best laser eye surgery New York has to offer.

Lasik Surgery: No More Four Eyes

Thursday, May 11th, 2006




If you are sick of wearing glasses or fiddling with contacts, you should consider laser eye surgery.

Laser surgery to correct your vision is a well tested procedure but is not for everyone so do not enter into it lightly. Done as outpatient surgery, most people are back to their normal routines in a couple of days and some report improved vision upon waking the next day! There are a couple of procedures availalbe and each has different recovery and vision improvement times - you should discuss each option with your doctor to find out which is best for your needs.

Laser-Assisted In Situ Keratomileusis (LASIK) is the most well known. In this procedure, a flap is cut in the cornea and then tissue is removed to reshape it. This surgery is fast and has a quick healing time of 2 days with immediate improvement in sight.

Photo Refractive Keratectomy (PRK) is the oldest of the procedures. This surgery reshapes the cornea by removing cells from the surface. The healing time is quite long - a month or more and there is a gradual improvement of vision over time.

Conductive Keratoplasty (CK) is a fairly new procedure. This surgery takes under ½ hour and has a very quick recovery time. It uses radio frequency energy to reshape the cornea and restore vision. This new procedure uses no laser or knife and is quite promising.

Although fairly safe,
lasik laser eye surgery is not fool-proof and in some cases may not work or in the worst case, you could end up with worse eye sight than before the procedure. Not everyone is a good candidate for the procedure and those with certain medical conditions such as glaucoma, diabetes or other eye disease should discuss this option with their doctor.

Lasik Laser Eye Surgery - What Actually Happens

Friday, May 5th, 2006



Laser eye surgery is fast becoming on of the most popular elective surgeries in the world today. It is a fairly straightforward procedure, but many people do not know how it is performed. This lack of knowledge may be stopping some good candidates for the surgery from having it done.



The surgeon will be performing the surgery with a rather large machine. While it may look intimidating, it is necessary as it has a camera, the laser and computer attached to it. The doctor will cut a flap in the cornea with a scalpel, and then switch to the laser for the remainder of the surgery. That is it. The laser eye surgery is completed. Now it is time for the recovery process to begin. Since the cornea is not sutured together after the surgery, the surgeon will place an eye patch over it. This patch will protect the cornea from being accidentally harmed.

When you go to the clinic for your procedure, you will be taken to a room with a recliner. This is where you will be seated. Your eye will be numbed and the eyelid clamped open to prevent blinking. Most patients return to work with in a couple of days and most normal activities with in a couple of weeks. Your recovery will, of course, depend upon you and your particular situation. However, you should expect to have better vision within a short amount of time following the surgery.

When you are contemplating laser eye surgery, also known as LASIK eye surgery, the first step is to speak with your eye care professional. Your doctor will be able to tell you if you are indeed a candidate. During the prescreening phase, they will go over a list of requirements such as:

No change in eye prescriptions with in the last year

That you have no eye diseases

That you can sit still for an hour straight

That you fully understand after surgery care


It is a good idea to have someone drive you to the clinic for the procedure, as you will not be able to see clearly enough to drive yourself. You may also experience light sensitivity for a short period of time.
