LASIK, LASEK and LASAK revealed

Monday, March 8th, 2010

Basically there are three eye surgery methods. All of them are called almost the same: LASIK, LASEK and LASAK. Those methods can be combined with two other treatments to give a better result. Those two methods are: Wavefront treatment and Aspheric treatment.

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.

Because the operation is made on the surface of the corneas, the LASEK surgery is especially good, if you have thin corneas. It is also better, if you suffer of dry eyes.

LASAK is the most modern method of eye surgery. The flap, which is cut off, is thinner than when using the LASIK method. Because of the saved corneal tissue, it is a great method if you have 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.

To improve the result even further, the Wavefront treatment can be used in combination with all of the three laser surgery methods. A special instrument is used to measure the irregularities on the corneal, and a kind of topographic map is created. A computer makes a range of calculations, so the laser surgery is carried out for the specific eye.

With Wavefront the treatment will be unique, which gives a better result. The night sight will also be better. Finally astigmatism in the eyes will be corrected better.

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.

Without the Aspheric treatment the eye will be more ball-shaped when operating using LASIK, LASAK or LASEK. The result is reduced contrast ratio and bad night sight. When using the Aspheric treatment in combination with one of the three eye surgery methods, the curve in the central part of the eye will be made larger; which copy the normal (untreated) eye. With this method this method the result will be better; sometimes the sight will be even better than when using glasses or contact lenses.

Why You Do Not Have To Fear A Lasik Surgery

Thursday, January 7th, 2010

Thinking about eye surgery using a Lasik procedure is a big step, and many people are a little hesitant to ask the questions that they have. The Lasik procedure, though widely talked about, is not discussed in detail, and people tend to fear the unknown. This article addresses some of the more commonly held fears, and talks about the experience for the vast majority of people that undergo a Lasik procedure.

In both Lasik surgery and all other kinds of operations, a common fear is about the pain during and after the operation. But a Lasik surgery is almost painless. Before the Lasik surgery is performed the eye will be applied with numbing drops. You will also be provided with a mild sedative to relax you and make you comfortable. So even though there can be a small pressure to the eye, you will not feel any pain.

Many people do also fear the actual operation where the laser is used to reshape the cornea to improve the sight. It can seem dangerous that the laser is used directly on the eye. And what if you look away? Will it hurt your eyes? There is nothing to worry about. The operation is only performed for about ten to fifteen seconds for each eye. And a sophisticated tracking system will make sure that the laser stops, if the eye is not in position.

Another common fear is the fear of “the scalpel”. All the eye surgeries use either a very small microkeratome blade or the laser itself to create the flap that is needed to perform the laser operation. So there is no reason the fear about a scalpel, because it is actually not used.

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, the risk of a serious permanent complication due to the Lasik procedure is less than 1 percent, and the risk of any permanent complications even if not serious (such as light halos) is 3 percent or less. It is extremely rare for a patient to not have improved vision after a Lasik procedure.

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.

Are you more bothered about the thought of the Lasik physician’s hand approaching your eyes? Right before the surgery your eyes will be dripped with drops that makes your vision black out for ten to fifteen seconds; long enough for the surgery 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.

What You Need To Know About LASIK Surgery

Wednesday, November 4th, 2009

Because it is gentle, fast, efficient and with few complications, the LASIK surgery is the most popular eye surgery type today. It is a great laser surgery for most people; no matter if they suffer from farsightedness, nearsightedness and/or astigmatism.

The PRK laser surgery has been further developed to the new LASIK form. In both surgeries the outer cornea layer is removed, so the laser can operate on the tissue. But while the PRK method is scraping the out layer of, the LASIK operation cut just a flap in the cornea that can be bent. After the surgery the flap can be put back in place

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 laser treatment takes between 30 seconds and two minutes. A special laser called an Excimer laser will be used. It is specifically designed to operate in the eye’s sensitive tissues. Finally the corneal flap is put back again.

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.

Most people will already at that time feel that their sight has improved. Over the next weeks will stabilize.

The eyes can feel a little dry after the operation. Dripping them with salt water might help.

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.

The age-related long-sightedness that all people will experience can also not be prevented by a LASIK operation.

The 3 Eye Surgery Methods

Saturday, October 10th, 2009

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.
