Phototherapeutic Keratectomy – PTK

The problem

The front of the cornea has an irregular shape causing irritation, reduced vision, contact lens intolerance or pain

This Excimer laser is used also for refractive surgery
A laser is required to smooth and polish the cornea restoring vision
During surgery, you will note an unusual smell from the gas discharge of the laser. This is NORMAL
The time for surgery is variable depending on the type of problem, around 30 minutes
No stitches are required, and a contact lens may be placed before padding the eye.
The pad is removed day 1.
The eye will be sore until the skin grows back over the cornea

The eye may appear slightly red, and this may last a few days
Discomfort is normal, especially in the first few days. Pain relief tablets will help
Vision may take several weeks to return to normal, as the skin of the eye remodels
You may need to change your glasses, and Dr Maloof will advise when this can be done
In some cases, the original disease process can recur years later

Leave the contact lens in place
Commence eye drops the next day after removing your pad
Take any pain relief prescribed
Continue any glaucoma eye drops
You may be given anesthetic drop for comfort. Please only use one drop every 4 hours, for 3 days
Expect some discomfort to sunlight or bright lights
