This treatment is a type of laser eye surgery used to seal blood vessels in the retina that are bleeding. Depending on the extent of a patient's condition, several types of the procedure can be performed. Focal photocoagulation is done when there is minor bleeding from just a few blood vessels in the retina. The procedure is usually an outpatient operation, and it does not require general anesthesia. Anesthetic eye drops are used to numb the eye before surgery instead. The eye is dilated with additional eye drops so the surgeon can see everything in detail. The surgeon will begin by identifying the bleeding vessels over a small area and seal these off one at a time with small burns from the laser. After the surgery, patients will need someone to drive them home. Their vision will be blurry for a few days, and there may also be eye pain or headaches during this time. This operation is typically done to help preserve existing vision and prevent additional vision loss in patients with diabetic retinopathy.
