Disadvantages We Should Know About Lasik Eye Surgery

Though LASIK eye surgery is reported to have several merits, such as no pain, less complications, higher successful rate and shorter recovery time, it also has disadvantages just as a coin has two sides. So before deciding to take this surgery, we must make ourselves fully notice these disadvantages, or else, we maybe dissatisfied with the treating result. Therefore, the following will introduce some disadvantages of LASIK eye surgery in order to help people to know more about it.

The first disadvantage is people may need to take repeat surgeries. After the first surgery, it may not achieve a satisfied treating effect, so people need to take follow-up procedures to further improve peoples vision. The advantage for the repeat surgeries is peoples vision can be further improved. And the down side is people have to face the pressure of repeat surgeries, and of course pay more money for the surgeries.

What We Should Know About Lasik Eye Surgery?

Though a large number of people worldwide have been benefited from LASIK eye surgery, it is a pity that there are still some people who do not know much about it but want to take it. We know we can resort to LASIK eye surgery for help to get rid of our glasses or contact lenses in our later life. However, we dont know not everyone can be suitable for the surgery and the surgery can not treat all the eye problems. So before we decide to take LASIK eye surgery, what should we pay attention to?

No doubt that LASIK eye surgery can help us a lot with our eye problems, but this does not mean everybody can be suitable for the surgery. If we want to be a good and qualified candidate for LASIK eye surgery, we should bear in mind the following points:

Important Information About Laser Eye Surgery

It seems as though there have been millions of seemingly successful procedures since laser eye surgery was first introduced in the United States in 1991. I see commercials for procedures all the time. I have not yet heard about any horror stories involving laser eye surgery nor have I heard about any class action lawsuits filed against the laser eye surgery industry. Unfortunately, I think that they will likely come one day. Like many people, I need a bit more convincing before I sign up for something that sounds as drastic as shaping your eyeball with a laser in order to see better.

You see, I have a light prescription for nearsightedness and would probably make a good candidate for this kind of procedure. I am still waiting for more evidence that this procedure is completely safe. It simply sounds illogical that a laser can be used to shape an eyeball without causing any residual damage. I am going to wait a good while to see if, even after decades, laser eye surgery causes any damage to the patient's eyes. I think that there should be many years of research and analysis completed before any procedure can be deemed harmless.

Laser eye surgery, like all surgeries or medical procedures, does have its complications. Some people experience double vision or a halo effect after the surgery. An important thing to keep in mind while trying to decide whether or not to go through with the procedure is that eye laser surgery is irreversible. There is no going back, folks. If getting laser eye surgery leaves you with unwanted or intolerable side effects, you may be stuck with them, forever.

Since its introduction, laser eye surgery has become more and more affordable which is a sign of a competitive market. It may also be a sign of waning standards in the young industry. Where I come from, you get what you pay for and this motto has served me well. I think that you are just asking for trouble if you sign up for any discount surgery. Those savings come at a price one away or another. Exactly what did they skimp on to save you money? That is one question that potential patients ought to ask themselves and their doctors.

I think that it is a good idea to wait a few more years before I give laser eye surgery much confidence. This is just one of those new things that have to have a while to sit before we can feel that we know all that we need to or should know about it. Laser eye surgery may be the lifesaver that many claim it to be but I think I'll wait a bit longer before I buy into it or bet my sight on it.

How Lasik Came to Be

Some people believe that the use of Lasik procedures has only occurred in very recent times. To most people Lasik and its associated technology are still novel concepts. However, Lasik's success is the result of improvements made on prior procedures.

Vision correction surgeries can be traced back over fifty years to when some of the first procedures were carried out. In 1948, Dr. Jose Barraquer developed a technique we would describe as barbaric and unethical by today's health care standards. Dr. Barraquer, who practiced in Bogota, Columbia, would remove and then freeze more than 50% of the patient's cornea. A lathe would then be used to carefully sculpt the surface of the cornea to increase the quality of vision. The cornea was then sewn back in place once it was redesigned.

The outcomes of this technique, which was known as MKM, or freeze myopic keratomileusis, were extremely variable and thus clinically unreliable. It could also be a very complicated and intricate surgery to perform. The technique seems barbaric, but Lasik's history is dependent upon the knowledge gained from those who came before. Today's Lasik can thank MKM's use of the basic version of microkeratome for advances in the industry.

Helping the development of the concept of vision correction was the understanding of some of the problems surrounding MKM. ALK was created over a decade later. To correct refractive errors, this technique used a modified microkeratome to create a flap at the front of the eye and then removed a wedge of corneal tissue. As happend with Doctor Barraquer's way of performing the surgeries, the effects of ALK could not be guaranteed.

Not long after the development of the automated lamellar keratoplasty method, a procedure known as radial keratotomy, or RK, was invented by a Russian physician. Doctor Fyodorov modified the prior procedure a little to produce more consistent results with a higher percentage of successful vision corrections. In an RK procedure, the cornea is sculpted using common, non-specialized surgical tools. Reshaping the cornea involved removing portions of the cornea in order to correct refractive errors, myopia (nearsightedness), and astigmatism.

Doctor Fyodorov's RK technique was more difficult but produced better results. However, it still produced poorer results than today's Lasik. His results were more reliable than previous techniques but still useless for refractive errors other than astigmatism or slight problems with nearsightedness.

For thirty years after Dr. Fyodorov's technique was applied to use in the eye, lasers were developed and used in correcting eye problems. The use of the excimer laser for the removal of corneal tissue was first described by the Steven Trokel in 1983. The laser was used in a procedure known as photorefractive keratectomy, which can now be used to treat up to 80% of the myopic population. PRK changes the shape of the anterior central cornea using a laser. PRK preceded the invention of Lasik, which affects the inner tissue of the cornea.

Lasik surgeries first appeared in 1991 when the procedure was first carried out in the United States. With this technique, predictable and accurate outcomes could be achieved for the first time. The first surgery to offer a speedy and often pain free surgery, Lasik can also boast a very short recovery period. Lasik's past has been a meaningful aid to the procedures we have today.
