What is keratotomy?

keratotomy is a type of eye surgery that is designed to improve the ability of the eye properly focus to reduce or remove the need for corrective lenses. Keratotomic surgery usually refers to one of two types of eye surgery, radial keratotomy or photorephractive keratotomy (PRK). The radial form of surgery usually includes an eye surgeon that makes small cuts in the cornea, a transparent layer in the front of the eye. On the other hand, the PRK includes the use of the laser to change the shape of the cornea. After performing the operation to remove glass from the eye of the injured boy, he made a surprising discovery that once the recovery was completed, the patient's eyes significantly improved significantly. This has led to the development of the surgery procedure to repair the brief attention by making cuts in the cornea from the pupil's eye, in the avzor similar to the rays of the wheel.

In this type of eye surgery, a very accurate diamond knife is used to perform cuts. The variation of this technique, called Arcuate keratotomy, uses forRuh cuts. This method is also known as astigmatic keratotomy and can be used to repair astigmatism, where blurred vision is caused by an uneven corneal surface.

Radial keratotomy in its original form is rarely used in modern eye surgery because it has been replaced by more advanced visual remedy methods. The board is one of these methods. It is normally done using local anesthetic and it is a relatively fast procedure, it takes about ten minutes to the eye. The eye surgeon uses an ultraviolet laser to transform the corneal surface. After surgery, a special type of contact lens called the contact lens is often used.

PRK is no longer as widely used as it has been in the past, because of the development of alternative methods of laser eye surgery. These include procedures known as laser-assisted sub-epithelial keratectomy (Lasek) and laser assisted IN-Situ keratomileusis (lasik) that use complex laser control computers. Usually a patient who has undergone a successful PK, Lasek or Lasik operation will experience a gradual improvement in his vision, which may fluctuate between clean and blurred for several weeks.
