Like\u00a0LASIK<\/a>\u00a0and other types of laser eye surgery, PRK works by reshaping the cornea using an excimer laser, allowing light entering the eye to be properly focused onto the retina for clear vision.\u2028 The main difference between PRK and\u00a0LASIK<\/a>\u00a0is that in LASIK surgery a thin, hinged flap is created on the cornea to access the treatment area, whereas in PRK the cornea\u2019s entire epithelial (outer) layer is removed to expose the area and no flap is created. For both PRK and LASIK, the excimer laser then sculpts the stromal layer of the cornea to correct your refractive error.<\/p>\n

A variation of PRK, called\u00a0\u0644\u06cc\u0632\u06a9<\/a>\u00a0\u06cc\u0627\u00a0LASEK<\/a>\u00a0, also is available. Instead of removing the outer epithelial layer of the cornea as with PRK,\u00a0LASIK<\/a>\u00a0LASEK involves lifting the epithelial layer (using a surgical instrument called a trephine), preserving it during surgery and then replacing it on the eye\u2019s surface at the end of the procedure.\nLASEK has decreased in popularity due to the slower recovery of vision compared with PRK, as the replaced epithelial layer takes longer to recover in LASEK than the growth of a new epithelial layer in PRK.<\/p>\n

<\/span>PRK VS.\u00a0LASIK<\/a><\/strong><\/h1>\n

The final results of PRK surgery are comparable to\u00a0LASIK<\/a>\u00a0outcomes, but initial PRK recovery is slower because it takes a few days for new epithelial cells to regenerate and cover the surface of the eye.<\/p>\n

There also is a slightly increased risk of eye infection and haziness of vision in the first few days after surgery.\u00a0LASIK<\/a>\u00a0\u0628\u0648\u062f\u0647\u060c \u0627\u0633\u062a\u0641\u0627\u062f\u0647 \u0627\u0632 \u067e\u06cc \u0622\u0631 \u06a9\u06cc \u062a\u0648\u0635\u06cc\u0647 \u0645\u06cc\u200c\u0634\u0648\u062f. \u0627\u0632 \u0637\u0631\u0641\u06cc \u062f\u06cc\u06af\u0631\u060c \u0637\u06cc \u067e\u06cc\u00a0\u0622\u0631 \u06a9\u06cc \u0627\u062d\u062a\u0645\u0627\u0644 \u0628\u0631\u062f\u0627\u0634\u062a\u0646 \u0628\u06cc\u0634 \u0627\u0632 \u062d\u062f \u0628\u0627\u0641\u062a \u0642\u0631\u0646\u06cc\u0647 \u0628\u0647 \u062d\u062f\u0627\u0642\u0644 \u0645\u06cc\u200c\u0631\u0633\u062f.<\/p>\n

How is PRK performed?<\/strong><\/p>\n

First, your eye surgeon removes a central area of corneal epithelium with an alcohol solution, a \u201cbuffing\u201d device or a blunt surgical instrument.\u2028Next, an excimer laser is used to precisely reshape the curvature of your cornea\u2019s surface. This computer-controlled, highly specialized laser delivers pulses of cool ultraviolet light that remove microscopic amounts of tissue in a precise pattern.\u2028A soft contact lens \u201cbandage\u201d is then placed on the cornea to help protect your eye. New epithelial cells grow back in five days typically, after which the bandage contact lens is removed by your eye doctor.<\/p>\n

<\/span>What to expect from PRK surgery<\/strong><\/h1>\n

<\/span><\/p>\n

<\/span>Before<\/strong><\/h2>\n

You must first choose an eye surgeon experienced in PRK surgery. You will then undergo a thorough eye exam to ensure your suitability for laser eye surgery. This will include an evaluation of:<\/p>\n

    \n
  1. The size of your pupils.<\/li>\n
  2. The moistness of your eyes, to evaluate the risk of developing dry eyes after laser eye surgery and treat accordingly.<\/li>\n
  3. Corneal curvature, using a corneal mapping device to precisely measure the contours of the front surface of your eye.<\/li>\n
  4. Corneal thickness.<\/li>\n<\/ol>\n

    Your eye doctor also will assess your general health and medical background, as well as any medications you are taking, to determine if you are a suitable candidate. If you wear contact lenses, you may need to stop wearing them for a period of time before your eye exam, as contacts can change the natural shape of your cornea. (Ask your eye doctor for specific advice about this.)<\/p>\n
