Many people around the world go for different types of vision correction treatments to regain their normal vision and get rid of the troublesome glasses or contact lenses once and forever. Out of all the available procedures for vision correction, the one that is the most popular is the laser eye correction treatment. Many clinics in cities such as Sydney and Adelaide are offering this treatment and helping thousands of people who are suffering from certain types of vision related problems such as long sightedness, short sightedness or astigmatism. And there are many reasons behind the ever growing popularity of this lased based treatment, including the fact that is very precise and effective.
LASIK is basically a combination of microsurgery and excimer laser procedure that has been developed specifically for the purpose of correcting a wide range of refractive problems related to vision. In most of the cases, patients are not required to wear contact lenses or glasses after the treatment as they are able to see clearly without using external vision aids. You might be a little surprised to know that exciemer laser was actually developed by a person of Indian origin in the USA. The person who discovered this laser was Rangaswamy Srinivasan. By working in tandem with eye specialists in the early 1980s, he was finally able to etch the cornea of the eye. And it was this experiment that actually led to the development of LASIK procedure.
LASIK surgery, as a treatment for vision related problems first came into being in the early 1990s. According to the latest figures, more than 25 million people around the world have undergone this surgery. As far as the market for refractive surgery is concerned, it exceeds more than $4 billion and is expected to grow at an exponential rate in the next few years. Refractive surgery includes all those laser based procedures which are performed to treatment certain vision related problems such as myopia, hypermetropia, astigmatism and prebyopia.
Among the most popular refractive errors procedures, the ones that top the list are LASIK and LASEK. There is one big difference between the two procedures. In LASIK, the main focus is on the stroma corneal tissue which is thinned out using advanced lasers. LASEK, on the other hand, concentrates mainly on the epithelial tissue which is made smaller with the help of advanced lasers. Both these procedures do not take more than 20 minutes for both eyes. There are best clinics available in Sydney for Laser Eye Surgery.
