Retinal Laser Surgery

Retinal laser surgery is a highly intense and tightly focused light source that can target the retina precisely and has no effect on other tissues on its path to retina or around it. Laser treatment, which is an advanced, noninvasive procedure, can preserve remaining vision and prevent vision loss in many people. This procedure is carried out in Tehran Noor Eye Hospital in Iran by experienced ophthalmologist using advanced equipment.

This is an outpatient and noninvasive procedure in which eye drops are used to locally anesthetize the eye and dilate the pupil. The patient sits on an ordinary chair, similar to an eye examination. This surgery is usually associated with a little pain and lasts for less than 30 minutes. The patient can return home immediately after this procedure.

Retinal diseases are mainly treated using thermal laser. The light energy is absorbed by a specific tissue in the back of the eye, and converted into heat by this type of laser. Thermal laser can be used for retinal tears, in order to seal blood vessels or remove abnormal tissues and vessels.

Most of the time, during retinal diseases, the eye appears normal even when there is bleeding or fluid leakage in the posterior parts. Vision may also be normal for a time, regardless of the vision-threatening risks. The only way that helps ophthalmologists diagnose any possible vision-threatening complication is performing a comprehensive dilated eye exam.

Retinal laser surgery is performed in Tehran-Iran Noor Eye Hospital to treat some specific diseases such as:

Diabetic retinopathy:

Diabetes is a disease that causes blood flow problems throughout the body. In this disease, the retinal veins may leak blood and result in edema or swelling. The vision of a person with diabetes changes when this edema occurs in the area of the retina responsible for central vision called macula. Retinal laser can seal the holes that cause fluid leakage and prevent more vision loss.

In some diabetic patients, new blood vessels grow in the retina to replace the occluded vessels. These vessels are not normal regarding the histological features and do not function properly, and even their bleeding can cause blindness in the person. The laser can remove these new vessels and prevent blindness.

 

Retinal Vein Occlusion

The small vessels that drain the blood from the retina will be blocked by aging. This phenomenon is especially seen in people with diabetes and hypertension. Retinal vein occlusion can cause the swelling of retina, which consequently results in bleeding, fluid leakage, as well as blurred central and peripheral vision. In other cases, new vessels may grow, which can cause severe pain and increase intraocular pressure. Laser helps reduce swelling and also prevents the formation of new blood vessels.

 

Age-Related Macular Degeneration

Some people develop some changes in the macula as a normal part of aging, which are dry and cannot be treated by laser therapy in many cases. The more serious type, the wet form, can cause macular edema due to bleeding or fluid leakage. Wet macular degeneration usually causes blurred vision without pain.

 

Retinal Detachment and Holes

Retinal holes can develop due to aging, ocular damage, severe nearsightedness and also by themselves without any causative factors.

 

Central Serous Chorioretinopathy

One or more blisters may develop in the macular region as a result of this disease. These lesions can cause blurry vision, abnormal color vision, temporary farsightedness, or blind spots. Although this condition resolves in most people by itself without undergoing any special treatments, sometimes retinal laser surgeries are required.

 

Ocular Tumors

Some benign tumors of the eye result in fluid leakage and retinal swelling. Laser can remove these tumors and resolve retinal swelling.

No preparations are needed before retinal laser surgery. The candidate can eat and take his/her other medications as usual.

 

Postoperative Care

Since the pupil is dilated in the process of treatment, it is necessary that someone accompanies the patient after the completion of the procedure. Besides, eye drops or any other type of medication should be used as ordered by the ophthalmologist. Wearing sunglasses is recommended after laser treatment.

 

Contraindications and Complications

After performing retina laser treatment, there would be no limitations for the patients and they can carry out all their daily activities. In many patients, after performing retinal laser surgery, no visual changes are observed. Although some may complain about blurry vision, and in some cases reduced vision at night or reduced near vision, during the first few months after this treatment, most patients will have no new visual complications after retina laser. Depending on the condition for which that the patient is treated, he/she may develop a blind spot or reduced peripheral vision at night after the procedure.

Q: Who is qualified to perform retinal laser surgery?

Q: Is the laser used for retinal laser surgery the same kind of excimer laser?

Q: Is retinal laser surgery painful?

Q: Is it normal to see sparkles during retinal laser surgery?

Q: Can we exercise after retinal laser surgery?

Q: Is there any need for hospitalization after undergoing retinal laser surgery?

 

 

Q: Does retinal laser surgery require more than one session?

A: It usually takes several weeks or months to see if retinal laser has been successful. In some people, for controlling vision problem and halt more vision loss, more than one laser session is needed. This especially occurs in patients with diabetic retinopathy and Angiogenesis.

 

Q: Who is qualified to perform retinal laser surgery?

A: This procedure is performed by retina sub specialists in Tehran-Iran Noor Eye Hospital .

 

Q: Is the laser used for retinal laser surgery the same kind of excimer laser?

A: No. Excimer laser is a kind of laser used for correcting refractive errors in surgical procedures such as LASIK, LASEK or PRK.

 

Q: Is retinal laser surgery painful?

A: In retinal laser surgery, the patient may feel a slight pain when the laser beams are focusing on the retina .

 

Q: Is it normal to see sparkles during retinal laser surgery?

A: Yes. Patients usually see sparkles in some stages of the surgery.

 

Q: Can we exercise after retinal laser surgery?

A: There are no limitations in doing daily activities. If you play or do a particular sport, be sure to consult your ophthalmologist before taking any action.

 

Q: Is there any need for hospitalization after undergoing retinal laser surgery?

A: No. Retinal laser surgery is an outpatient and noninvasive procedure and after surgery the patient will be discharged from the hospital, clinic or the ophthalmologist’s office.
