Laser Surgery for Eye-Refractive-Errors

Laser Surgery for eye has become very purposeful for people suffering from different types of eye-problems, refractive-errors or eye-diseases. The most common form of laser eye surgery is Laser-assisted in Situ Keratomileusis. Generally it is known as LASIK, in short term. This laser treatment is performed on patients suffering from myopia (also known as nearsightedness), hyperopia (also known as farsightedness) and astigmatism. Different types of refractive surgery are performed by expert eye-doctor or eye-surgeons. Most of the laser treatments for eye work by reshaping the cornea. IN LASIK procedure, cornea is reshaped to enable light entering the eye to be properly focused onto the retina for clearer vision. Typically, the procedure is not associated with any pains. It is pain-free, in most cases. And it is so quick and fast that it can be completed within 15 minutes for both eyes. Till now, laser eye surgery procedures have marked great success in order to achieve effective results as it helps in improving vision or refractive error so that patient(s) can have correct vision. More importantly it helps in eliminating need to wearing eye-glasses or contact lenses. Depending on expert’s evaluation and patient’s refractive-error (if patient is not a good LASIK candidate) then number of other vision correction surgeries is available too.  For example: custom wavefront LASIK, Epi-LASIK, IntraLase “Bladeless” LASIK and LASEK. Other surgeries are PresbyLASIK and PRK. The procedure of laser surgery for eye involves following process:

Eye-surgeon uses a mechanical surgical tool to create a thin and circular ‘flap’ in the cornea. Then the hinged flap is folded back to access the underlying cornea. The underlying cornea is called thestroma. Some corneal tissue using an excimer laser is removed. This excimer is a highly specialized laser that uses a cool ultraviolet light beam to remove microscopic amounts of tissue from the cornea to reshape it. This is done so that it more accurately focuses light on the retina for improved vision. Once the laser reshapes the cornea, the flap is then laid back in place, covering the area where the corneal tissue was removed. And cornea is allowed to heal naturally. This process may require topical anesthetic drops to numb eyes and to eliminate the discomfort. This process is not associated with any bandages or stitches.
