Phototherapeutic Keratectomy (PTK) is a laser surgery that helps to repair the cornea. Prior to the creation of this advanced surgery, patients with a corneal issue would’ve needed a transplant. But not anymore. PTK surgery uses the precision excimer laser to remove roughness or cloudiness from the cornea. The cornea is part of the front of the eye that is transparent. It covers the iris, pupil, and anterior chamber. If the surface of the cornea is rough or cloudy then it blocks the rays of light from focusing properly on the retina, so images are then blurry. The laser can create a smoother corneal surface with small amounts of tissue being removed.
The phototherapeutic keratectomy surgery helps to address issues of the cornea, such as:
- Recurrent erosion syndrome
- Corneal Dystrophies
- Corneal Scars
- Certain Corneal Infections

This procedure is done at an outpatient center and under topical anesthesia. During the procedure, the ophthalmologist will use the excimer laser on the desired location. The laser uses photoablation and breaks the bonds between the molecules. This system is very precise in the removal of the damaged corneal tissue.
The recovery from this procedure is fairly quick, only taking a few days. You may need to wear a contact lens following the surgery in order to protect your eye. It is usually removed by your ophthalmologist at Boston Vision. Eye drops will also be prescribed to use following the surgery.
Boston Vision is one of the few practices in Boston that offers this advanced PTK technology. If you would like to learn more about this procedure and how it can help you, book an appointment online or try giving us a call at 617-202-2020.
