Everywhere you look there seems to be ads for LASIK eye surgery. The way they advertise the procedure can make you think that is will be the perfect solution to your vision problems. No more straining to read the ingredients on food packets or road signs. Simply undergo LASIK surgery and all there hassles will be a thing of the past.

However it is important to note that LASIK eye surgery may not be suitable for everyone so it’s important to read up as much as possible out the procedure.

The acronym LASIK means laser in-situ keratomy, eye surgery and uses an excimer which is a powerful laser. These have been specially designed to work on the delicate eye area. The laser can quickly re-shape the cornea (for treating nearsightedness) or the hyperopia (for treating farsightedness).

When the cornea is reshaped what happens is that tissue underneath is removed. So that the tissue can be worked on, a very small flap is pulled back from the surface of the cornea. The laser or microkeratome blade can be used to create this flap.

The laser zaps away excess tissue determined by the ophthalmologist whilst viewing an extremely detailed image of the cornea. This process can take only a matter of minutes and the patient won’t feel a thing. Vision can be corrected so swiftly that they are able to drive home aftwards.

The primary consideration when deciding if LASIK is for you is to look at the costs involved. Many health plans don’t cover this procedure as they believe it to be purely cosmetic.

The cost of surgery can vary greatly however the costs generally reflect the use of a reliable and experienced ophthalmologist and will cost several thousand dollars per eye. The cost is certainly not insignificant.

Cost isn’t the only consideration however. You can only undergo surgery if you have healthy eyes which have stopped changing. Other situations can also arise which prevent surgery.

When you go for your first consultation a number of tests will be performed to detect eye problems or diseases which could cause problems with the surgery. Because of hormones, LASIK surgery cannot be performed on pregnant women or on people with suppressed immune systems.

If you have the money to spend on surgery then LASIK may be a good way to improve your vision. The success rate is very high and the procedure is painless. There aren’t many reasons not to go ahead with treatment.

Lasik Eye Surgery Risks Include Loss of Vision

Most often, patients of lasik eye surgery are pleased with the results of the refractive surgery but they should be aware that it does involve certain risks and that is why it becomes necessary for them to understand the various types of lasik surgery risks.

This would involve studying and understanding the possible risks which may include losing vision, developing a debilitating visual symptom, under-correction or over-correction or developing severe dry eye symptoms. Some patients have disappointing results and refractive errors that may occur, farsighted patients may see results diminish with age, and also there is not enough long term data available to ensure long-term safety and effectiveness of lasik surgery.

Device Malfunction, Flap Migration, Inflammations and Infections

In addition, there are other lasik eye surgery risks such as malfunction of devices used in the procedure, migration of the flap, and inflammation or infection developing. There are instances when a patient loses lines of vision on the vision chart that may not be able to be treated by glasses, contact lenses or surgery and this is a grave lasik surgery risk.

There may also be lasik eye surgery risks such as the patient developing glares, halos and/or double vision that may seriously hinder nighttime vision and the patient may not be able to see well in low contrast situations. The numbers of patients who achieve 20/20 vision as a result of lasik surgery are few and so may need additional treatment though such additional treatment may not always be possible. This is another lasik surgery risk.

There is also considerable lasik eye surgery risk in that the patient may not be able to produce enough tears so that the eye remains clean as well as moist and comfortable. There is considerable discomfort caused by dry eyes and it may reduce the quality of vision because of intermittent blurring as well as other symptoms of vision. Such a condition may sometimes become permanent and may require intensive drop therapy as well as using plugs or some other procedures for treatment and is certainly another serious lasik surgery risk.

The patient would be well advised to discuss with the doctor their expectations and be prepared that sometimes the results would not match high expectations. In case of farsighted people, the amount by which the vision can be improved as a result of having lasik eye surgery would decrease as one grows older and this may be another lasik surgery risk. Also, there is not enough long term data to help the medical professionals glean more knowledge about this relatively new technology and so the long-term safety and effectiveness of lasik eye surgery is not really known.



The Benefits Offered By Bladeless LASIK Eye Surgery

The risks involved in LASIK eye surgery is relatively small compared to other types of surgery. However, there is still a risk which is there because of the use of the blade that is used to cut the flap in the cornea. The use of this blade comes with the element of human error. This is because all human beings make mistake from time, although this risk is reduced the more highly trained someone is. However, this risk is still there.

Bladeless LASIK lowers that already small risk even further as it removes the need for a blade. This function is taken over by IntraLase lasers which are controlled by computers and can therefore provide a more precise cutting action. Because bladeless LASIK is so delicate that it can even be used on people who have thin corneas. These are people who usually not approved for other types of laser surgery.

Bladeless LASIK offer a number of advantages. The IntraLase laser used during bladeless LASIK allows for an increased curvature, hence lowering the margin of error even more. The fact that a laser is used instead of a blade leads to less infections and irritation. Not only that, bladeless LASIK only leads to a shorter recovery period compared to other types of LASIK eye surgery.

Before bladeless LASIK, many people who had surgeries had to come back for follow-ups or to redo a surgery that didn’t go so well. There is also a great deal of irritation that follows other surgeries. However, with bladeless LASIK most of these are something of the past, because of a success rate that is very close to 100%.

So now you may wonder, why do we need an eye doctor for if the lasers are doing everything? Well even though many of the actions are controlled by lasers, these lasers still have to be directed. And to be able to do that you need to have the knowledge of both laser technology as well as eye surgery, which only a trained LASIK eye surgeon can give you. Surgeons who do bladeless LASIK now also need to know how to operate the computer that controls the InterLaser lasers.

Although bladeless LASIK may cost a bit more, many people think it is worth spending that extra money, considering the near perfect results you get. Not to mention the reduced irritation and shorter recovery time.



Lasik Eye Surgery – What you Should Know

Dana Siconolfi asked:


Every year millions of nearsighted people decide that they’re tired of wearing glasses and begin looking for a more permanent solution to their eye problems. In the not too distant past, the solution would have meant going through a procedure called radial keratotomy in which incisions to the eye are made with a precision calibrated diamond knife.

Nowadays, most of these people are gaining 20/20 vision with the relatively new procedure of Lasik eye surgery. It was only a bit more than ten years ago that the FDA approved Summit Technology’s excimer laser to be used to correct nearsightedness.

So what exactly is Lasik eye surgery? The acronym “Lasik” stands for Laser-Assisted In Situ Keratomileusis. Lasik actually combines two distinct vision techniques for correcting the eyesight.

First, a knife, called a microkeratome is used to cut a flap in the cornea. The cornea is the translucent front part of the eye that acts as a protection for the eye. It also acts as the lens of the eye and controls the entry of light into the eye. The way light passes through the eye determines how well we are able to see the outside world. Common eye defects such as near sightedness are caused by refraction errors, that is, errors in the way light passes through the cornea.

The second vision technique used in Lasik is a computer-controlled laser which is used to vaporize a portion of the stroma, one of the five layers of the cornea. The stroma is, by far, the largest part of the cornea. It is essential to controlling the refraction of light through the cornea.

Parts of the stroma are vaporized to flatten the cornea. The amount of stroma that needs to be vaporized depends on your degree of nearsighteness. Once this is done, the cornea flap is replaced to its original position.

The combination of these two techniques allow surgeons to precisely correct the refractive errors in the eye that prevent you from having 20/20 vision.

Even though millions of people every year opt for Lasik surgery as a way of completely eliminating their dependence on glasses, refractive surgery is not to be taken lightly. Eye surgery is not trivial.

You will need to find not just a clinic, but also a physician who is experienced in vision corrective surgery. In fact, finding the right physician to perform your Lasik surgery is the most important decision you will make. Remember, you are about to place your future vision in the hands of whichever specialist you choose.

This is an exciting time for medical discoveries. The rate of new discoveries in the medical world are taking place at a dizzying pace. New and improved methods of surgery techniques are discovered and implemented everyday. You will want to find a doctor who keeps abreast of the latest developments in refractive eye surgery techniques and who is an active participant in the operations themselves.

If you take the time to choose the right physician, one you feel comfortable with and who is able to explain to your satisfaction, both the benefits and the risks involved, you should have no problems with your Lasik surgery.
