Wavefront Lasik Makes Splash In Eye Surgery

Monday, April 30th, 2007

Did you know that traditional eye examinations are designed to detect just two corneal abnormalities - cylindrical and spherical? A cylindrical corneal abnormality results in astigmatism, while a spherical abnormality results in myopia and hyperopia (near sightedness and farsightedness).

Eye surgeons now have available a new technology that makes vision correction more precise. It’s called “wavefront”.

To correct poor vision Lasik eye surgery has become the popular choice. Lasik surgery links the condition of the patient’s visual system to the Lasik laser for correction.

The incisions performed on the cornea of the eye are customized to the patient’s individual needs. Accurate data concerning the condition of the patient’s eyes is all important. The better the data collected on the condition of the eyes the better the result of the surgery. Wavefront technology as become the most promising method for collecting this necessary information.

Wavefront technology is a technology that is capable of measuring refraction at multiple points on the eye as light is reflected upon it. This creates a “map” of the patient’s eye. Because each eye is unique the data from each eye must be carefully analyzed so that the Lasik laser maybe properly programmed.

Conditions within the cornea of every eye affect refraction. Some of these refractions are considered higher-order aberrations, which have been traditionally associated with irregular astigmatism. The ability to treat these aberrations can result in an improved outcome after Lasik surgery. This can increase the possibility of achieving 20/20 vision, or better.

Clinical trials using wavelength technology have shown that nearly 80%25 of Lasik eye surgery patients undergoing custom surgery achieved 20/20 vision. This is a higher number than those who underwent traditional Lasik surgery.

Another benefit of wavefront is in determining which patients are not candidates for Lasik surgery. Lasik surgery can actually exacerbate existing visual problems for some people

Wavefront technology can detect an infinite number of aberrations by using a fixation target along with an input laser beam. A wavefront sensor is used to measure the slope of the wavefront as it exits the eye. Then software determines the exact targets and dimensions of needed incisions.

When the laser light beam enters the eye, it produces a flat wavefront. In the perfect eye, a wavefront that is still completely flat will reflect back. In reality this beam of light will travel through a crystalline lens that is imperfect. The light then goes through an irregular cornea and other parts of the eye. All of this in combination causes the wavefront beam to become irregular; this provides the valuable data that determines the present shape of the cornea.

After wavefront is used to evaluate and diagnose existing aberrations in the eye, it is used to create the exact procedure for reshaping the cornea.

Wavefront technology is not new. It has been around for quite some time, but only recently has it been used to aid in the correction of human vision. Did you know that wavefront has been used for years by astronomers? Wavefront is used for adjusting the optics in their telescopes. When the reflecting mirror inside a telescope becomes deformed (as the cornea of an eye) it can be adjusted using wavefront data. The data resulting from wavefront technology is used to remove aberrations. In astronomy the Earth’s atmosphere must be eliminated just like removing the aberrations found with astigmatism in the eye.

The bottom line: Wavefront technology is an advanced method for creating precise and individualized prescriptions for Lasik eye surgery patients. With wavefront, patients are more likely to have a successful Lasik experience.

Lasik - Finding The Right Surgeon

Monday, April 30th, 2007

Though LASIK surgery is a relatively simple procedure, you should still take special care when considering it. After all, a poorly performed surgery will affect your vision for the rest of your life. One of the most important things that you can do when considering LASIK surgery is to carefully choose your surgeon.

So how do you go about finding a good LASIK surgeon? Most likely you will have seen many advertisements announcing the now widely available procedure. And with the surgery being so widely available, you may have noticed that many are performing the procedure at really attractive rates.

However, while many of these practices may be competent, choosing your LASIK surgeon based purely on an advertisement is not a wise decision. Sure, advertisements can be good starting points, but there are other things that should be considered also.

One thing to consider is if your potential surgeon is associated with an academic medical center. Practitioners that are associated with medical centers are more likely to be abreast of current information and technology. If possible, you should choose a surgeon who is a Fellow of the American College of Surgeons, as their standards for acceptance are pretty rigid.

Another avenue for helping you choose a LASIK surgeon is a referral from your regular optometrist or ophthalmologist. Still another resource for helping you to locate a LASIK surgeon is the Academy of Ophthalmology’s website at www.aao.org using the “Find an Eye M.D.” feature. Choose refractive surgery under specialty. You may also call refractive surgery centers in your area.

After you have settled on a potential surgeon, you need to make an appointment for a consultation. Ask any questions that you may have concerning the surgery - it helps to take along a list. If you are having problems thinking of questions, you can visit The Council for refractive Surgery Quality Assurance’s website to get an idea of what you should be asking.

You should also choose a surgeon who is competent in the different areas of refractive surgery, such as LASIK, LASEK, PRK, CK, and clear lens replacement. He should also be informed of the latest technologies in refractive surgery. A surgeon who is competent in all areas of refractive surgery will be able to make the best recommendation for correcting your vision.

Just as you might when considering any other surgical procedure, feel free to consult with several surgeons before making your final decision. It is also important that you are comfortable with your LASIK surgeon and trust that he is competent. You should never feel obligated or pressured to choose a particular surgeon. Be sure to base your preference for a LASIK surgeon on what is best for you and your health.

The Risks Of Lasik Surgery

Monday, April 30th, 2007

The 21st century is the golden age for surgical procedures, among them an increasingly popular method of corrective eye surgery known as LASIK. LASIK is an acronym for the surgery, which stands for Laser Assisted In Situ Keratomileusis. This procedure has become increasingly reliable, with unresolved complications reported in only 3 to 6 percent of patients. The risk of complications is still there, however, and can take several different forms.

The complications of LASIK surgery can include the following: Dry eyes, over or under correction, visual acuity fluctuation, halos or starbursts around light sources at night, light sensitivity, double vision, wrinkles in the flap, striation, decentered ablation, debris or growth under the flap, induced astigmatism. These complications are classified according to whether they arise in the preoperative procedures, the procedure itself, or after the operation either early on or later.

Each of the complications is unique unto itself, and it is important to remember that LASIK surgery is irreversible should nay of the complications occur. May of the complications such as halos and ghosts are not tested by standard eye tests, and need to be accounted for separately.

Over and under correction are the result of the surgeon incorrectly estimating the concentration that needs to be applied during the surgery. Many risks of LASIK surgery can also be increased by phenomena that may not have occurred to the patient, such as racial origin and environmental occurrences.

Improperly formed flaps can lead to an irregular surface and vision defects as the flap fails to properly adhere to the surface of the eye. This condition can be corrected with further surgery, although the costs will usually continue to accrue and sometimes a decrease in visual acuity. A flap that is too thick can also weaken the eye’s surface and result in bulging. Some patients have a condition that already makes them conducive to bulging, and thus are rejected as candidates for LASIK surgery.

As LASIK surgery become more an more commonplace, the risks and recovery times are becoming less common and pronounced. As with nay surgery, and especially those with cosmetic implications, LASIK is becoming increasingly popular. As people sense the money to be made in practicing the procedure, the risk of employing a surgeon who is not versed or experienced enough in the procedure also increases. Make sure to discuss LASIK surgery with your ophthalmologist before undergoing the procedure, to determine if you are eligible and also to suggest a list of surgeons who practice the procedure in your area. Make sure to contact other patients that have undergone the surgery by the particular surgeon you are thinking about employing in order to gain some first hand knowledge about her practice and success rate. Also look into where the surgeon was educated and if she served under another surgeon before going out to do the procedure on her own. There is no such thing as being too careful when it comes to surgical procedures, and treatment for your eyes are no exception.

lasik eye surgery Example Title

Monday, April 30th, 2007

Often times you haven’t even done anything to get buggered eyes. By that I mean you haven’t actually personally damaged them to the point of needing visual aid. If you’re like many you were just born with buggered eyes, and have had to deal with the hassles of glasses or contacts for a time that is too long to remember.

Is it worth it? - The hassle. That is the question that you should be asking yourself. Contacts came and made it more convenient, but what now? Eye surgery! Eye surgery has been around for several years now, and it’s amazing at how many people are still skeptical about it.

What is Lasik Eye Surgery?

Good Question - Glad you asked. Lasik is an acronym that stands for Laser-assisted In Situ Keratomileusis. It’s a procedure in which a laser is used to correct the shape of the eye, an as a result to correct the vision of the patient.

The first form of Lasik surgery was in 1970, when Dr Jose Barraquer, made it possible by developing the first microkeratome. The microkeratome is used to cut thin flaps in the cornea and alter its shape, in a procedure called keratomileusis. Building off the work of DR Barraquer Dr. Lucio Buratto in 1990 %26 Dr. Ioannis Pallikaris took the technique and made it widely effective and safe.

With the long history that is behind the surgery, there is not a need to be skeptical. I would recommend talking to your eye doctor, to gain more advice on the surgery and to see when and if it’s right for you. Good luck, happy sight!

People Help Inform Other People About Eye Surgery

Sunday, April 29th, 2007

Nearly 500,000 people in the Unnited States will have eye surgery this year. Almost none of them will have gone into surgery well informed. The Eyesurgeryinformation.com website is normal people talking to normal people making it easier for them to make an informed decision. (PRWEB) December 15, 2005 — Nearly 500,000 people in the United States will have eye surgery this year. As the population ages, that number will grow to 1 million. Almost none of them will have gone into surgery well informed and some of those people will be needlessly blinded. Eyesurgeryinformation.com wants to change that. Doctors try to inform their patients with charts and graphs but in reality they talk medical jargon to non-technical people. With eye surgery being a $1 billion industry, there is a lot of marketing hype and a lot of social pressure on people to get surgery. There are downsides, however, that most people don%26#8217;t realize. In an article about Lasik surgery on the Eyesurgeryinformation.com website the Federal Trade Commission states the following: - Lasik is surgery to a very delicate part of the eye. - Hundreds of thousands of people have had Lasik, most very successfully. - As with any surgery, there are risks and possible complications. - Lasik may not give you perfect vision. The American Academy of Ophthalmology (AAO) reports that seven out of 10 patients achieve 20/20 vision, but 20/20 does not always mean perfect vision. - If you have Lasik to correct your distance vision, you’;ll still need reading glasses around age 45. - Lasik surgery is too new to know if there are any long-term ill effects beyond five years after surgery. - Lasik surgery cannot be reversed. - Most insurance does not cover the surgery. - You may need additional surgery %26#8212; called “enhancements” %26#8212; to get the best possible vision after Lasik. Dan Foley, CEO of Eyesurgeryinformation.com said. %26#8220;People have only five senses and vision is highly important to quality of life. We want people to be informed about their options when it comes to their eyes.%26#8221; Foley also said, %26#8220;We want our site to be normal people talking to normal people. This will make it easier for them to make an informed decision.%26#8221; If you would like additional information about Eyesurgeryinformation.com visit the website at http://www.eyesurgeryinformation.com or call Dan Foley at 952-944-7754. ###
