Photocoagulation is a medical procedure that uses laser light or other forms of intense light to destroy tissue. It is most commonly used to treat eye conditions such as retinal detachment, diabetic retinopathy, and age-related macular degeneration. It can also treat certain types of cancer. In photocoagulation, a high-energy beam of light passes through the eye to the retina, destroying abnormal blood vessels or tissue.

This type of surgery destroys abnormal blood vessels in the retina. It can also be used to shrink tumors and remove tissue for biopsy.
The photocoagulation treatment procedure is performed by delivering a burst of light energy to the back of the eye. This light energy causes the blood vessels to seal, which prevents them from leaking and causing vision loss. In most cases, the procedure is performed on an outpatient basis, meaning that you can go home the same day. You will be asked to sit in a chair and look at a target light during the procedure. The doctor will then use a special instrument to deliver the light energy to the back of your eye. You may feel a brief sensation of heat or pressure during this process, but it is generally well tolerated. The photocoagulation treatment procedure is usually performed one or more times, depending on the severity of your condition.

After the photocoagulation procedure, ophthalmologists recommend that patients return 100-200 days later for follow-up care. During this appointment, the ophthalmologist will check to see how well the patient's eyes have healed and whether the photocoagulation effectively treated the patient's condition. If necessary, additional treatments may be recommended at this time. In most cases, however, patients will only need to return for routine check-ups after their initial follow-up appointment.
Overall, photocoagulation is a safe and effective treatment for many eye conditions. With proper technique and experience, most risks can be minimized. If you are considering this procedure, be sure to discuss all of the risks and benefits with your surgeon.
After the procedure, you will be observed in the recovery room for a short time. Once you are awake and alert, you will be able to go home. You may experience a mild discomfort and blurred vision for a day or two. It is important to avoid rubbing your eyes and wear sunglasses outdoors. Your doctor will give you specific instructions on caring for your eyes and when to return for a follow-up visit. Recovery times vary depending on the type of photocoagulation performed. For instance, if you have diabetic retinopathy, you may need to have the procedure repeated every few months to keep the condition under control. In general, however, most people only require one treatment.
