Myopia, Hyperopia, Astigmatism, Presbyopia is the main refractive errors of eyes. Myopia or nearsightedness occurs when you are able to see the objects near to you clearly but the far objects are appeared blurry. In this case the eyeball might be longer as compared to its normal size or might be curving in sharply. Astigmatism is referred to as the distorted vision. In this case the shape of eyeball surface is somewhat irregular as compared to normal eyeball surface. In Presbyopia condition, eyes progressively loose the ability to focus on near objects with the age.

Radial keratotomyis a popular treatment procedure for astigmatism; in this, a precision calibrated diamond knife is used to make cuts circumferentially parallel to the edge of cornea. During Photorefractive Keratotomy surgery a small amount of tissue from the corneal stroma is removed by vaporization using an excimer laser to change the shape of the anterior central cornea.

LASIK is the best option for vision correction. Lasik surgery for eyes is also a laser eye surgery procedure. It is same as Photorefractive Keratotomy (PRK) procedure but it provides a faster patient recovery and can remove all three types of refractive errors Myopia, Hyperopia and Astigmatism.

Short sightedness, or myopia, is mostly an affliction where an individual is able to see clearly close up but has blurry eye-sight in the long distance. The greater the level of short sightedness, the closer an object must be before it's distinct. Ordinarily, short sightedness is usually remedied utilizing glasses or maybe contact lenses which will modify just how light travels in the eye, redirecting the rays to the back of the eyeball. Laser eye treatment pertaining to myopia functions by transforming the front area on the eyeball (cornea) in order that rays of light traveling though the eyeball land on the back of the eyeball (retina).

There are many laser eye surgery clinics all over the country. These clinics are usually private clinics with their own set of laser surgeons, eye doctors, and specialists. Clinics are involved with the patient before, during, and after the procedure. These tests can either be done at the laser surgery clinic or with your personal eye doctor. The IntraLase Method of LASIK surgery is becoming very popular with patients and eye care professionals alike. The IntraLase Method is also known as "All laser LASIK" because instead of using the microkeratome to create the corneal flap, the eye care professional uses the IntraLase laser.

The options for LASIK surgery were not very extensive. There was really only way LASIK was performed and that involved a small mechanical blade called a microkeratome being used to create a flap on the cornea, after which a conventional excimer laser was used to reshape the tissue underneath so that the cornea would be able to focus light directly on the retina. LASIK, in the past, used a surgical blade called a microkeratome with advanced technology, the procedure has changed quite drastically, and now there is blade-free LASIK surgery.

Vision correction surgery is needed to remove the eye refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), astigmatism and presbyopia. An eye vision correction surgery is required in case you need a permanent solution against the refractive errors. Vision correction surgery can benefit the patients of myopia, hyperopia and astigmatism. There are various Vision correction surgery procedures and option available today to treat the vision problems.
