Laser Eye Surgery | PRK Eye Surgery Procedure

PRK or photorefractive keratectomy is a form of laser eye treatment that is still used particularly where patients have larger than average pupils or thin corneas. It is used to treat near and far sighted and those with astigmatism. The improvement is not as rapid as with Lasik and will happen steadily from a few days to a few months.

You may be given a sedative before the procedure. Your eye is first anesthetized with drops and your eye will kept open with a suction ring device. Even if you are having both eyes done they will have the procedure done one after the other and not together. The operation is done using an excimer laser to remove minute bits of tissue from the cornea in order to reshape it and allow it to focus light onto the retina. The amount of light and length of time it takes depends on the computerised details of your prescription. Although the laser is a cool ultraviolet light beam there may be a slight burning smell but it is all over in a matter of minutes.
