Phototherapeutic keratectomy (PTK)

PTK, or phototherapeutic keratectomy, is a type of corneal surgery using photoablation with an excimer laser.

• improved visual acuity
• increased patient comfort through the reduction of pain, light sensitivity and tearing
• complete elimination or reduction of irregular astigmatism, compromised night vision, light splitting and other problems associated with corneal abnormalities

• The whole procedure takes only a few minutes. Laser treatment itself does not take more than 30-60 seconds.
• You will not feel any pain due to topical anaesthetic drops. You will not see any surgical instruments and you will focus your eyes on a special target that guarantees eye stability during surgery.
• After laser treatment is completed, a protective lens will be placed on the eye.

• You should not drive motor vehicles until you doctor approves of it.
• Do not touch, press or rub your eyes.
• You may feel some discomfort such as tearing, increased light sensitivity, moderate eye tenderness and grittiness.
• During the first week you should avoid eye strain: limit your time working at the screen, watching TV or reading books.
• Follow all postoperative instructions.
• Use sunglasses when outside in the sun for about 3 months.

The first follow-up is performed about 15 minutes after the procedure; the whole visit may take approximately 1.5-2 hours. On the first few days after the procedure you should strictly follow your doctor’s instructions regarding medication and follow-up visits.
