Phototherapeutic keratectomy (PTK)
Introduction to Phototherapeutic Keratectomy (PTK)
Phototherapeutic Keratectomy (PTK) is a laser-based treatment used to correct a variety of corneal conditions. It is minimally invasive and generally highly effective. A laser is used to precisely remove damaged or irregular corneal tissue, allowing for the restoration of visual acuity and the improvement of overall eye health.
Common reasons for having PTK treatment are: recurrent corneal erosions, corneal scars or opacities. These can occur due to corneal dystrophies, trauma, infections, or previous eye surgeries, and can significantly impact vision.
How does the procedure work?
The procedure of Phototherapeutic Keratectomy is a well-established and highly precise surgical technique. Before the surgery, the patient receives topical anesthesia to the eye to ensure comfort. The surgeon then uses an excimer laser to ablate the damaged or irregular corneal tissue, following a predetermined treatment plan.
The excimer laser emits pulses of ultraviolet light, which are absorbed by the corneal tissue, causing it to evaporate. The laser is programmed to remove a specific amount of tissue based on the patient’s individual needs. This precise ablation allows for the reshaping of the cornea and the removal of any abnormalities.
During the procedure, the surgeon carefully monitors the cornea to ensure accurate tissue removal. The laser is quick, taking seconds to minutes. Exact time depends on the extent of the corneal condition being treated. After the procedure, a protective contact lens is placed on the eye to aid in the healing process and assist with pain relief.
If you have symptoms of a corneal disease, or have been diagnosed with a corneal condition, it is essential to consult with a corneal sub-specialist.
