Lasik surgery explained
While Lasik vision correction has been getting a lot of publicity nowadays, few know about the details of the procedure. Lasik Vision Correction is one of the most dynamic procedures in medicine and health – and perhaps the most exciting one in ophthalmology. In essence, Lasik surgery tries to correct vision errors regarding refraction such as myopia or nearsightedness, astigmatism or distorted vision, and hyperopia or farsightedness.
While different surgical techniques are used by various Lasik surgeons today, the American Academy of Ophthalmology states that eye surgeries that make use of lasers are the most advanced procedure nowadays in terms of technology. State-of-the-art equipment allows for more precision and accuracy in correcting vision problems.
There are two procedures that make use of an excimer laser: PRK or Photrefractive Keratectomy, and LASIK, or Laser in situ Keratomileusis. PRK also operates on the principle of altering the shape and structure of the cornea so as to give clearer vision. The laser used is highly precise and accurate. The laser uses beam made of ultraviolet rays to make very tiny cuts at a rapid pace.
LASIK is a bit more complex than PRK. In this procedure, the surgeon cuts a flap in the eye to allow access to the laser. As opposed to the PRK where a machine is used for almost the whole procedure, the success of LASIK relies on the skill and expertise of the surgeon who will perform the operation.
Laser eye surgery entails little to no discomfort. Those who underwent any of the two types of surgery usually go back to work within a few days. There were some reports of long-term side effects, but these are very infrequent.
