The Popularity Of Lasik Eye Surgery By Candice Sabrina At Isnare.com Ezine Articles

There are few among us who, at one time or another, had not had to manage some level of impaired vision. Whether age has rendered us no longer able to see far away or up close, or we have suffered an illness or disease that has compromised our vision, it is likely that, if we have not already, we will someday need corrective measures to help us see at our best.

And for those who have long managed the expense and inconvenience of eyeglasses and contact lenses, the idea of corrective eye surgery seems most appealing. It's no wonder, therefore, that Lasik eye surgery has continued to grow in popularity since it was first performed in the United States in 1991.

Lasik is relatively new on the scene to us – the consumers; but in actuality the technology has been a long time coming. In fact, in 1948, Columbian ophthalmologist, Jose Barraquer first experimented with corneal procedures by actually surgically removing more than half of a patient’s cornea that he then froze. Once the cornea had been frozen to an appropriate temperature, Dr. Barraquer was able to reshape its surface thus removing barriers to clear vision.

Once the cornea had been reshaped it was replaced into the patient’s eye. Such technology evolved by the 1960s to the point where such corneal procedures could be done without removing the cornea from the patient’s eye; this procedure was perfected and performed in Russia and involved the use of a scalpel.

Lasik began to take shape in the early 1980s when a U.S. ophthalmologist made alterations to laser technology that had begun to be used by the U.S. military. But in 1990, Lucio Buratto and Ioannis Pallikaris developed the Lasik surgery that we know today by combining methods of two pre-existing techniques – keratomileusis and photorefractive keratectomy. Both keratomileusis and photorefractive keratectomy are techniques in which the cornea is reshaped with the use of an excimer laser or other technology.

The word Lasik refers to Laser-Assisted In Situ Keratomileusis and is a form of refractive laser eye surgery that was first performed in the United States in1991. During the procedure, the patient’s eye is immobilized with the use of a cornea suction ring after which the surgeon creates a flap through an incision made in the top layer of the corneal tissue.

The flap is then lifted back to reveal the mid-section of the cornea – known as the stroma. The surgeon then uses a low-powered excimer laser to resurface the stroma. The corneal flap made during the procedure is then replaced over the stroma; the healing process is natural and generally speedy. The procedure itself is very quick – usually less than 10 minutes an eye – and virtually painless. The most discomfort experienced by the patient is general anxiety in anticipation of the procedure.

Today, over one-million people in the United States alone have undergone Lasik surgery – generally with very good success. In fact, it is a very small percentage of patients – less than 6% - who have experienced any complications following their procedure. Such complications generally include light sensitivity, dry eye, double vision, and scarring. These incidences, however, are very rare and can be greatly reduced by having your procedure performed by a reputable and experienced surgery center.
