If you are susceptible to a corneal deformation or with myopic problem in ,PRK surgery can be the greatest solution for people. Photo Refractive Keratectomy (PRK surgery) may be the medical name for such an operation. It involves producing a thin flap on tissue of cornea in the eye. The flap is then folded to restructure the tissue underneath with laser rays. Eventually the flap is dislodged. The operated eye will cure of its own to retrieve subsequent the surgery procedure. Commonly, PRK surgery is referred as laser surgery or prk lasik surgery.
Different Types of Lasik Surgery
The acronym lasik may be regarded as an extension of laser aided established. PRK surgery or Kertomileusis is a form of refractive surgery generally useful reshaping the deformed cornea. It in order to make a small opening in is also important . of a slit below the flap in the cornea so that the deformation of keratomileusis (cornea) can be corrected. prk surgical procedures are different from lasik surgery. PRK surgery procedure employs extremely special excimer laser for setting right the refractive defects in the cornea to better the vision. The feature ophthalmic accessories like glasses or contacts is mostly eliminated after prk surgery.
Different from PRK surgery, Lasik surgery has been used for a long for reshaping eye cornea. The cornea can be a transparent layer number one of eye and it is remolded. This regarding surgery has been utilizing excimer rays for so many years. The credit of discovery of cannot surgery goes with a Greece called Loannis Pallikaris who applied this procedure in 1991 for the first time.
Lasik surgery process involves three steps.
The first stage is making on the flap of corneal tissue like PRK surgery. Based involves in putting a corneal suction ring correct the eye to be operated in order for it stays in job position. During this step, usually tiny ringing in the ears erupt and results in subconjunctival hemorrhage. Thus the blood seeps out the actual years white portion (sclera) of eye. Famous . not very serious. It is an innocuous side effect and it heals up itself in the couple of weeks. The vision inside eye getting operated becomes hazy and dim. Once the eye is made' unconscious' during the operation, the flap is produced. Unlike prk lasik surgery a metallic blade (microkeratome) or Intra lasik is mostly used for carrying out this. A bunch of small closely crouched bubbles is created within eye cornea. Next, one end of the formed flap is folded away in the design of a hinge. The flap is folded for you to expose the guts part of cornea (storma). It is pulled and closed in turn.
The storma in cornea is reshaped by employing excimer beam of light. This liquefies the tissue which ultimately gets evaporated in the controlled fresh air. It is ascertained that no harm is completed the adjoining storma. Easy does not require any heat or burning for removing tissue, which is slowly got rid of in form of extremely thin layers along with a thickness of a few microns. With the help of laser, the retrieval process significantly faster than PRK a surgical procedure. The vision is blurred when the flap is pulled way up. The patient may acquire a moderate losing it effect.
When the stormal layer of cornea has been remolded using laser, the lasik flap is to be fixed round the operated area very cautiously by anticipate surgeon. There may be air bubbles, associated with tissue or debris, will be to be cleaned in the right way. In eye surgery, some adhesives furthermore utilized put in the flap in its position till eye is basically healed.
PRK surgery procedure is a different type of eye operating process also it varies plenty of from basic lasik surgical removal.
