Photocoagulation is a medical procedure that uses intense light, typically in the form of a laser, to destroy tissue. It is primarily used to treat eye conditions such as retinal detachment, diabetic retinopathy, and age-related macular degeneration. Additionally, it can be used to treat certain types of cancer by targeting abnormal tissue. During photocoagulation, a high-energy beam of light is directed through the eye to the retina to eliminate abnormal blood vessels or tissue.

This procedure targets abnormal blood vessels in the retina and can also be used to shrink tumors or remove tissue for biopsy.
Laser surgery
The procedure is performed by delivering a burst of light energy to the retina, causing blood vessels to seal and prevent leaking that could lead to vision loss. The procedure is generally done on an outpatient basis, allowing the patient to go home the same day. During the surgery, the patient will look at a target light, and the doctor will use a specialized instrument to direct the laser energy to the affected area of the eye. While some heat or pressure may be felt, the procedure is generally well tolerated. It may need to be repeated depending on the severity of the condition.
After the procedure, you will be observed for a short time in the recovery room. Once you are alert, you can go home. Some mild discomfort or blurred vision may occur for a day or two, and it is important to avoid rubbing your eyes and wear sunglasses outdoors. Specific post-operative care instructions will be provided, and follow-up visits will be scheduled. Depending on the condition being treated, additional sessions may be needed to maintain control, but many patients only need one treatment.
Patients are typically scheduled for a follow-up appointment 100-200 days after the procedure to check how well the eyes have healed and whether the treatment was effective. If necessary, additional treatments may be recommended. For most patients, routine check-ups are sufficient after the initial follow-up.
