Important Reasons to Choose LASIK Eye Surgery

Important Reasons to Choose LASIK Eye Surgery (a type of laser eye surgery)

There are many reasons to choose LASIK eye surgery but If you're currently sitting on the fence when it comes to deciding whether or not to have LASIK eye surgery performed in order to improve your vision you're probably not alone. Everyday more and more consumers suffering from various vision impairments are opting to have laser eye surgery performed in order to improve the quality of their eyesight. However, the reasons for every person seeking out this vision correction treatment may differ. Some folks simply don’t want to wear contacts anymore; others may have just gotten fed up with wearing eyeglasses. No matter what your motivation may be, the decision to have eye improvement surgery is no small task and it should be considered carefully.

As mentioned in the previous paragraph, perhaps the number one reason most people undergo vision correction surgery or LASIK as it is commonly referred to, is so they no longer have a valid need to wear corrective lenses or glasses. Let's face it although LASIK isn't that cheap (prices do continue to drop) the money spent on replacing contact lenses and ordering the supplies necessary to keep them working properly can add up over your lifetime. LASIK eliminates this cost requirement. Even your glasses will need to be replaced as they wear out or your current eye prescription no longer provides the clarity of vision that many people seek. Also for many folks there is always a time when they have either lost or misplaced their eyeglasses only to never see them (no pun intended) again. These replacement costs can get rather large so the funds saved by having laser eye surgery performed may actually turn out to be a large amount when looked at over a period of time.

For many active or sports minded people LASIK offers them an opportunity to continue to compete in athletic activities without the physical constraints of having to wear contact lenses or eye glasses. Even swimming takes on a whole new level of pleasure as you no longer need any eyewear to allow you to see clearly after you have undergone LASIK surgery. I can personally remember attempting to play baseball and football while growing up with glasses on. This was a major hassle since they constantly fogged up and the perspiration really mucked up my glasses. LASIK not only improves your eyesight it also allows a freedom that many folks who were stuck with using corrective eyewear as they grew up have yet to experience. For many this is one of the main reasons to choose LASIK eye surgery.

LASIK also appeals to those individuals that need to indulge their vanity side by allowing them to ditch the glasses they have been wearing in order to see more clearly. With the way human nature is, wearing eyeglasses can leave many people feeling unattractive or self-conscious about the way they look. Laser vision correction surgery provides an immediate boost in the self-confidence of almost everyone that has the surgery performed. Not only can they see better, but now they also feel better about themselves due to no longer having the constraints of needing corrective eyewear.

LASIK eye surgery is a procedure that solves many of today's more common eye impairments and problems. However, it also provides a way to save money by eliminating the normal wear and tear and daily costs associated with other vision correction eyewear such as contacts and glasses. Additionally, LASIK also injects anew sense of confidence in the consumers that undergo the laser eye surgery treatment. If you're still undecided about having LASIK performed keep in mind the items discussed throughout this article. Doing so may just provide the clarity that you need in order to make the right decision.

The Technical Development of Lasik Laser Eye Surgery

Let's find out about the technical development of Lasik (one type of laser eye surgery)

Technological development

The LASIK technique was made possible by the Colombian-based Spanish ophthalmologist Jose Barraquer, who, around 1950 in his clinic in Bogotá, Colombia, developed the first microkeratome, used to cut thin flaps in the cornea and alter its shape, in a procedure called keratomileusis. He also provided the knowledge about how much of the cornea had to be left unaltered to provide a stable long-term result.

Later technical and procedural developments included the RK (radial keratotomy) started in the 70’s in Russia by Svyatoslav Fyodorov and the development of PRK (photorefractive keratectomy) in the 80’s in Germany by Theo Seiler.

In 1968, at the Northrup Corporation Research and Technology Center of the University of California, Mani Lal Bhaumik and a group of other scientists, while working on the development of a carbon-dioxide laser, would develop the Excimer laser, where molecules that do not normally exist come into being when xenon, argon or krypton gases are excited. This would form the cornerstone for LASIK eye surgery. Dr. Bhaumik announced his discovery in May of 1973 at a meeting of the Denver Optical Society of America in Denver, Colorado. He would later patent it. [1]

The introduction of Laser in this refractive procedure started with the developments in Laser technology by Rangaswamy Srinivasan. In 1980, Srinivasan, working at IBM Research Lab, discovered that an ultraviolet excimer laser could etch living tissue in a precise manner with no thermal damage to the surrounding area. He named the phenomenon Ablative Photodecomposition (APD).[2]. Dr. Stephen Trokel published a paper in the American Journal of Ophthalmology in 1983, outlining the potential of using the excimer laser in refractive surgeries.

Using these advances in laser technology and the technical and theoretical developments in refractive surgery made since the 50's, LASIK surgery was developed in 1990 by Lucio Buratto (Italy) and Ioannis Pallikaris (Greece) as a melding of two prior techniques, keratomileusis and photorefractive keratectomy. It quickly became popular because of its greater precision and lower frequency of complications in comparison with these former two techniques. Today, faster lasers, larger spot areas, bladeless flap incision, and wavefront-optimized and -guided techniques have significantly improved the reliability of the procedure as compared to that of 1991. Nonetheless, the fundamental limitations of excimer lasers and undesirable destruction of the eye's nerves have spawned research into many alternatives to "plain" LASIK, including all-femtosecond correction (Femtosecond Lenticule EXtraction, FLIVC), LASEK, Epi-LASIK, sub-Bowman’s Keratomileusis aka thin-flap LASIK, wavefront-guided PRK, and modern intraocular lenses.
