Laser Vision Correction Sydney

More recently, laser eye surgery has also been used to correct presbyopia (which is the inability to focus on nearby objects.) This is part of the normal aging process and can be corrected by using reading glasses.

The reason that a laser is able to correct so many different types of conditions is because it is able to reshape the surface of the eyeball so that the sight is restored and the patient can see perfectly again and no longer has the need to wear glasses or contact lenses.

There are two main types of laser treatment for vision. The first type is PRK (Photo-Refractive Keractomy), which uses a laser beam guided by a computer to vaporise tissue on the cornea. After this type of laser treatment the healing is completed in about a week. The second type, LASIK (which stands for Laser Assisted in situ Keratom) is more complicated. A surgeons makes an incision in the cornea lifts it and then uses a laser to remove amounts of tissue form the inside layers of the cornea. The healing process for this also takes about a week.
