PTK laser surgery, or phototherapeutic keratectomy, is a procedure used to treat corneal issues that affect vision. It is performed using an excimer laser to reshape the corneal surface and remove opacities that obstruct the passage of light.
During PTK laser surgery, the ophthalmologist applies topical anesthesia to numb the eye. Then, an excimer laser is used to precisely remove the affected layers or opacities from the cornea. This allows light to pass more clearly through the cornea, improving vision.
What are the benefits of the PTK laser surgery?
This surgery offers several benefits, including:
- Improved vision
- Reduction or elimination of corneal opacities
- Increased contrast sensitivity
- Enhanced quality of life
Who is a good candidate for the surgery?
This procedure may be an appropriate option for people with corneal problems that affect their vision, such as:
- Corneal dystrophies
- Corneal scars from infections or trauma
- Actinic keratitis
- Post-surgical corneal opacities
Recovery is typically quick, with most people able to resume normal activities within a day or two. However, it is important to follow your ophthalmologist’s instructions, which may include using eye drops or protective shields for a certain period.
