More Facts About Eye Laser Surgery

Friday, August 27th, 2010

When someone is long or short sighted and cannot see things clearly it can have an impact on their lives. The reason for this problem is a misshapen cornea in the eyeball. Laser eye surgery works by correcting this defect so that the patient can see without the use of glasses or contact lenses. LASIK is most commonly used these days.

Done under a local anaesthetic the surgeon will cut a flap above where the cornea is whilst the eye is held open. The flap is lifted to reveal the cornea which is then shaped by the laser so the vision is corrected. There is no need for stitches and healing is usually simple and quick.

The benefits of this type of surgery are vast. The patient will no longer have to scramble around in the morning to find their glasses before getting out of bed. There is a major reduction in the need for paying for glasses, frames, lenses and contact lenses as well as the insurance needed in case they are broken or lost.

Sporty people benefit from this corrective procedure a lot. Some sports especially those requiring contact mean that wearing glasses is not only going to slow them down but it can also be hazardous. Contact lens wearers won’t have to suffer from dry eye or the risk of infection any longer either.

Not every one can have laser on their eyes however. If someone has very severe long or short sightedness then this procedure isn’t for them. The patient needs to be over 21 and have a prescription that has stayed the same for around 2 years. Any previous problems or injury to the eye usually means laser is a no go.

One thing to remember is that laser eye surgery is not permanent and it often needs topping up after a number of years. There are also risks such as infection, reaction to anaesthetic and over correction. It can also not treat ageing eye problems such as presbyopia.

The Benefits Of Laser Surgery

Saturday, June 5th, 2010

Light amplification by the stimulated emission of radiation or in other words laser, is a device that is used in laser surgery. This is done by using a strong, bright light which focuses on a specific area. Individuals who suffer from ruptured blood vessels, diseased tissues, or would like to have cosmetic surgery, will benefit from this form of treatment.

Different varieties of lasers are available. Some of them are the carbon dioxide laser or CO2, the pulsed dye laser, or the yttrium aluminum garnet or YAG. Each one is designed for a different use due to varied light beam colors. The type of operation and color of the tissue determines which one is used.

There are many reasons for this surgery being done. For example, those who suffer from tumors of the brain or liver may have them removed. This is done with only a small amount of scarring or damage to the actual surrounding tissue. Sealed lymph vessels will reduce swelling. This will also reduce spreading of tumor cells. Certain blemishes such as moles, tattoos, warts, skin tags and hair removal may be removed. Other certain types of cosmetic procedures are done as well. If postoperative surgery is an issue, the nerve endings will be sealed in order to reduce pain.

Only dermatologic surgeons should perform the procedure. This is due to their extensive training, background, and experience within the skin care field. As with any physician, be sure to check references and qualifications before proceeding any further.

The procedure is done by slicing, sealing, or vaporizing blood vessels and skin tissue by means of light. This light travels in only one direction. The timing and intensity will vary with the surgery that is needed. Anesthesia may be used.

Decreased infection and a bloodless surgery are just some of the advantages. Because the incision is precisely controlled, there is less chance for a skin injury. The actual operation is usually an outpatient procedure and the patient is allowed to go home shortly afterwards.

As with any operation, there are some risks that may happen. This might include pain, scarring, bleeding, infection, and a change of skin color. Sometimes, the operation is not effective at treating the problem.

Laser surgery has its advantages and is completely safe. There are different time frames when it comes to the recovery period and will depend on the individual. The actual expectations and procedure itself will vary also. Before surgery, talk with your doctor about your estimated recovery time and the prognosis.

LASIK, LASEK And LASAK Revealed

Monday, March 8th, 2010

There are three different to use when doing eye surgery; all of them with almost the same name: LASIK, LASEK and LASAK. The three surgery methods can be combined with two extra methods to give an even better result. The names of the two treatments are: Wavefront and Aspheric.

LASIK is the most popular of the methods. It is fast, effective and gentle. And complications using this laser surgery method are very rare. For most people, LASIK surgery will be a good method to improve their sight.

The LASIK operation is painless, and the sight will be improved in only a few hours. There are only a few side effects like dry eyes. The method can be used for near-sightedness until -12 and long-sightedness until +3.

The other surgery method called LASEK (or E-LASIK or ELSA) is great for people, who are only a little near-sightedness or and long-sightedness (from -2 to +2).

If you have thin corneas the LASEK surgery is a great method, because the laser surgery is made on the surface of the corneas. It also more gentle, if you have very dry eyes.

The newest type of laser surgery is called LASAK. The flap, which is cut off, is thinner than when doing LASIK surgery. That saves the corneal tissue and is therefore a better method for people with thin corneas.

The healing time is also shorter with LASAK than the other methods. The risks of complications are lower, and it is almost painless after the operation. The sight will also be steadier and the eyes will not be as dry.

The surgery result can be improved even more, if the methods are used in combination with the Wavefront method. The irregularities on the corneal are measured with a special instrument, and a kind of topographic map is constructed. Finally a computer calculates the correct settings for the laser surgery based on the specific eye.

The Wavefront method gives a more unique measurement of the eye. That gives an improved result and a better night sight. Astigmatism in the eyes will also be corrected in a better way.

Aspheric treatment is the newest step in eye surgery; and is used in combination with LASIK, LASEK and LASAK. The treatment takes into account that the cornea is not ball-shaped; but aspheric.

When using LASIK, LASEK or LASAK without Aspheric treatment, the eye will be more ball-shaped. That gives a reduced contrast ratio and a bad night sight. If the Aspheric treatment is used, the curve in the central part of the eye will be made larger (as it is in an untreated eye). This gives a much better result; sometimes even better than with contact lenses or glasses.

Why You Do Not Have To Fear A Lasik Surgery

Thursday, January 7th, 2010

Lasik eye surgery is a big thing for many people; and most of them do not dare to ask all the relevant questions. The Lasik surgery is normally not discussed in details; so many people have an (actually) unnecessary fear. Here in this article those details are discussed.

One of the most common fear, both when it comes to the Lasik surgery and any operation in general is the fear of pain during and after the surgery. When a Lasik surgery is performed the eye is applied with numbing drops. The patient also receives a mild sedative so they can relax and feel comfortable. So even though you may feel a minor pressure to the eye, it is relatively pain free

The next step is the actually eye surgery, where a laser is used to reshape the cornea. It is a common fear that they laser is shot directly into the eye, or that you might look away, so the eye is hurt. But the laser has a tracking system that makes sure that it is only use when the eye is in the correct position. And further more the laser is actually only used for ten to fifteen seconds for each eye.

Another general fear for people contemplating a medical procedure is fear of “the scalpel”. Any Lasik procedure uses only a very small microkeratome blade to approach the eye, or some more recent Lasik innovations have the laser itself created the flap and avoid using any hard surface at all. There is no reason to be concerned about a scalpel, for the Lasik physician does not use one.

You hear horror stories every day about operations that went wrong, so it is just natural to wonder about the risks; especially the risk about going blind. But there have never been reported any cases of blindness due to a Lasik operation according to government statistics taken by the FDA.

Actually is the risk of a serious permanent complication less than one percent. And the risk of any permanent complication, including minor complications like as light halos, is less than 3 percent. It is extremely rare that the sight isn’t improved after a Lasik surgery.

If the thought of being awake and having your eyes open during the Lasik procedure bothers you, remember that you will be given a mild sedative for the procedure, and that your eyes will have numbing drops administered to them.

If the thought of actually seeing the Lasik physician’s hand approaching your eye is bothersome, be comforted that the surgeon applies drops to the eye that blacks out the vision in that eye for ten to fifteen seconds, which is long enough for the procedure to be done for that eye.

The Uniqueness of Lasik Surgery

Tuesday, November 24th, 2009

Eyes, though small, are a complex but very important organs of our body. Eyes act as one of the main bridges between external objects and the brain. We rely mostly on our eyes for judging objects. If we ignore our eyes, it will be a terrible price to pay. Out of the many afflictions that may affect the eyes, refractive errors are quite common. We can get this problem corrected by wearing glasses, contact lenses or through a Lasik surgery.

In Lasik surgery, a laser is used underneath a corneal flap for reshaping the cornea. For correcting refractive errors, enhancing vision and for getting rid of glasses and contact lenses, you can go in for a lasik surgery in which a special laser is used. It was in’91 that one Loannis Pallikaris of Greece developed this procedure and from then on, more and more innovations are happening on this front.

During the Lasik eye surgery, the surgeon creates a hinged corneal flap with microkeratome, pulls back the flap and reshapes the cornea with excimer laser. Each patient will have a pre-specified pattern. The surgeon repositions the flap onto the cornea and sutures are usually not needed for this.

Though different varieties of lasers are used in ophthalmology, the one that is used in lasik surgery is a specific one called excimer laser. Many manufacturers make this special laser. There are many types of lasik surgery including conventional type.

Conventional lasik procedure mainly depends on the patient’s past history and glass prescription and hence the parameters for every patient are unique. Occurrence of rare complications such as glare, halos and night vision are not ruled out in conventional lasik surgery.

Some unavoidable complications may occur in Lasik eye surgery. You should also consider your occupation before you opt for lasik eye surgery. Your employers must be kept informed and only on obtaining their clearance, you should undergo this surgery. Further, you should have had a stable vision all through. If you suffer from advanced autoimmune diseases like lupus or rheumatoid arthritis, you should not opt for lasik surgery. If you have a decreased corneal strength resulting in a disease called keratoconus, then also, you can not risk opting for lasik surgery.

Laser Eye Surgery is an interesting topic and you will see Laser eye surgery as the main topic so go to the links to see what information there is available.

What You Need To Know About LASIK Surgery

Wednesday, November 4th, 2009

LASIK is the most popular type of eye surgery today. It is at the same time fast, efficient and gentle. And the complications of are rare. For most people a LASIK surgery is a good solution to improve their sight in the cases of nearsightedness, farsightedness and/or astigmatism.

LASIK technique is a further development of the older PRK laser surgery. Both operations are done by removing the outer cornea layer, so the laser can remove the tissue. The difference is that while the PRK eye surgery scrapes the outer layer of the cornea away, the LASIK surgery will cut a flap in the cornea that can bend. After the surgery the flap will be put back again.

The operation itself takes only a few minutes and is completely painless. The eye will be anaesthetized right before the surgery, and most people will not feel any pain at all. Subsequently the flap will be cut and the laser surgery can be made.

The actual operation only takes between 30 seconds and two minutes. A laser specially designed for operating in the eye’s sensitive tissues will be used. After the operation the flap is put back in place.

You can go home right after the operation. Because the eyes may sting a little bit, it is recommended to rest for the rest of the day; and maybe also take a nap.

Right after the operation the sight will have improved for most people. Over the next weeks it will be stabilized.

After the eye surgery the eyes can feel a little dry. It is therefore recommended to drip them with a little salt water.

All studies indicate that a permanent sight improvement is provided by the LASIK operation. And previous bad eyesight will not return again. But a possible, natural change of sight in the future is not possible to prevent by the operation. So the surgery should not be done before the sight is stable.

A LASIK laser treatment can also not prevent the age-related long-sightedness that all (even normally sighted people) will experience.

The 3 Eye Surgery Methods

Saturday, October 10th, 2009
by Martin Elmer

There are three different to use when doing eye surgery; all of them with almost the same name: LASIK, LASEK and LASAK. The three surgery methods can be combined with two extra methods to give an even better result. The names of the two treatments are: Wavefront and Aspheric.

Because it is fast, gentle and effective, LASIK is the most popular method. There are very few complications, so it will be a good eye surgery method for most people.

LASIK surgery is almost painless, and the sight has improved only a few hours after the operation. The side effects are few; dry is the most common. LASIK can help most people; long-sightedness until +3 and near-sightedness until -12.

For people who are only a little long-sightedness or near-sightedness (from -2 to +2), the LASEK surgery is a great method.

If you have thin corneas the LASEK surgery is a great method, because the laser surgery is made on the surface of the corneas. It also more gentle, if you have very dry eyes.

The newest type of laser surgery is called LASAK. The flap, which is cut off, is thinner than when doing LASIK surgery. That saves the corneal tissue and is therefore a better method for people with thin corneas.

LASAK do also have a shorter healing time than the other operations. There is no pain after the surgery and the risk of complications is very low. The eyes will not be as dry as with the other operations, and the sight will be steadier.

The surgery result can be improved even more, if the methods are used in combination with the Wavefront method. The irregularities on the corneal are measured with a special instrument, and a kind of topographic map is constructed. Finally a computer calculates the correct settings for the laser surgery based on the specific eye.

By using the Wavefront method, the result will be better because of the unique measurement of the eye. The method does also give a better night sight and astigmatism in the eyes will be treated with a better result.

The newest improvement in eye surgery is called Aspheric treatment; which is used together with one of the three surgery methods. The cornea is aspheric and not ball-shaped; something the Aspheric treatment takes into account.

When using LASIK, LASEK or LASAK without Aspheric treatment, the eye will be more ball-shaped. That gives a reduced contrast ratio and a bad night sight. If the Aspheric treatment is used, the curve in the central part of the eye will be made larger (as it is in an untreated eye). This gives a much better result; sometimes even better than with contact lenses or glasses.

Lasik Surgery

Wednesday, April 15th, 2009

lasikLaser Vision Correction is now in its second decade of helping patients reduce or eliminate their dependence on glasses and contact lenses. As testimony to its life changing benefits, thousands of ophthalmologists and optometrists around the world have become so impressed with the results of laser vision correction that over one million procedures are now performed each year. At Black Hills LASIK Center our patients continuously tell us they appreciate our commitment to being on the cutting edge of this exciting technology.

Heavy patient demand for laser vision correction has inspired surgeons and laser manufacturers to make tremendous advancements in both Excimer laser technology and surgical technique. When laser vision correction was first performed in 1988, only low to moderately nearsighted patients without astigmatism could be treated. Today, with the second and third generation Excimer lasers, very low to moderately high degrees of nearsightedness, farsightedness and astigmatism can be effectively treated. And for many patients that had large pupils, thin corneas or other contraindications for laser vision correction, newer surgical techniques now allow them to enjoy the benefits of clear vision without dependence on glasses and contact lenses. Only a few years ago these patients would not have been good candidates for laser vision treatment.

Laser Vision Correction at Black Hills LASIK Center

All laser vision correction procedures are not the same. Because of our dedication to excellence, Black Hills LASIK Center is recognized as one of the premium eye care providers in the area. Our surgeon is highly trained in a number of laser vision correction procedures. And we’ve invested in the laser vision technology needed to provide you with the best possible care.  Dr. Kowal has successfully performed thousands of vision correction procedures and is ready to help you choose the option that’s best for your individual vision problem, whether you’re nearsighted, farsighted or have astigmatism.

Pricing

The cost of vision correction varies among practices, based on surgeon experience and what the center includes in the fee. We are not the least expensive providers because we never sacrifice safety to save you money. We have invested heavily in advanced laser technology and our diagnostic technology is second to none. This investment is extremely important to surgical results and our patients tell us they can see the difference. We encourage you to attend a seminar at our clinic, and visit other laser centers to compare. Please download our “How to chose a laser vision provider” form, found in Patient Forms.

It’s only natural to want to get the best price, but remember, quality and service are extremely important when it comes to medical care. After all, laser vision correction is a procedure you’ll have only once in your lifetime and your vision is one of your most important assets. The best way to find out exactly what your price will be is to schedule an exam. After a comprehensive evaluation to determine what procedures you’re a candidate for and what degree of correction you need, we’ll be able to give you a specific price.

A few insurance companies do pay for all or part of vision correction procedures. You can check with your plan administrator, or we will be happy to make a copy of your insurance card and check coverage for you. Many people have medical flex plans they use to save up to 50 percent on their procedure by using pre-tax dollars. Your employer’s human resources department can tell you whether you have this benefit. Vision correction may be tax deductible as a medical expense (check with your financial advisor).

If you do not have insurance coverage, we do offer affordable payment plans starting as low as $84 per month for both eyes. It is easy to apply online and receive credit approval before you schedule an appointment. We also accept cash, personal checks, Visa and MasterCard.
