Laser Procedure
A retinal laser uses a concentrated beam of light to precisely treat targeted areas of the retina without damaging the surrounding structures of the eye. Unlike lasers used for refractive procedures such as LASIK or PRK, retinal lasers are designed specifically to treat conditions affecting the back of the eye.
Retinal laser photocoagulation is an in-office procedure used to treat a variety of retinal conditions, including retinal tears, diabetic retinopathy, macular edema, and retinal vein occlusion. It is commonly used to seal retinal tears and help prevent retinal detachment, as well as to treat abnormal blood vessels and reduce further retinal damage, helping preserve vision.
How Retinal Laser Treatment Works
Retinal laser treatment works by creating small, controlled areas of scar tissue on the retina. These scars can seal retinal tears, reduce leakage from abnormal blood vessels, and slow or stop the growth of new abnormal vessels. While laser treatment cannot restore vision that has already been lost, it can help preserve existing vision and reduce the risk of future vision loss.
What to Expect During Treatment
Retinal laser treatment is an in-office procedure performed while you are awake. Before treatment, dilating eye drops are used to enlarge the pupils and allow your physician a clear view of the retina. This process typically takes 20–30 minutes.
Numbing eye drops are then applied to keep you comfortable during the procedure. In some cases, a specialized contact lens is gently placed on the eye to help your physician visualize and treat specific areas of the retina. The laser is then directed precisely to the area requiring treatment.
During the procedure, you will see bright flashes of light and may experience mild discomfort or a sensation of pressure. Most patients find the bright lights more noticeable than the laser treatment itself. The length of treatment varies depending on the condition being treated, but most procedures are completed in less than 30 minutes.
What to Expect After Treatment
It is common to experience blurred vision, light sensitivity, or temporary changes in color perception immediately after treatment. Because your eyes will remain dilated for several hours, sunglasses are recommended, especially outdoors.
Some patients may notice mild aching, irritation, tearing, or hazy vision for a few days following the procedure. Over-the-counter artificial tears can help relieve dryness and discomfort.
The effects of the laser treatment continue to develop over the following 1–2 weeks. Your physician may recommend temporarily limiting certain activities before returning to your normal routine. Most patients can resume normal activities, including work, the next day.
If you experience significant pain, worsening vision, or other concerning symptoms after treatment, contact your physician promptly.
