What is laser retina surgery?
Retinal laser surgery, or scientifically known as “laser photocoagulation”, is a surgical procedure that uses lasers to destroy blood vessels and abnormal tissues that reside in the retina, or intentionally create scars to treat another problem.
The laser was discovered in the fifties of the last century, and some research was done to use the laser medically in the seventies, and indeed it has been used to treat many health problems for decades, and on top of these treatments comes the treatment of retinal diseases, such as the treatment of diabetic retinopathy for example and other diseases.
How is laser retina surgery performed?
The laser retina operation is performed in an outpatient clinic or the doctor’s office, and usually, in the process of optical coagulation the laser is used to create a microscopic burn in the target tissues, and immediately before the operation, the doctor gives you a drop that works to expand the pupils, and it is possible to apply local anesthesia In the eye, you may experience some minor pain during the injection or feel discomfort, but you will not feel anything during the procedure itself.
During the optical coagulation process, you will sit and place your chin in the place designated for it, do not worry, as this place is designed in a way that makes you feel comfortable during the procedure, then the doctor will then put a special lens with a mirror that helps the doctor direct the laser, and the doctor will ask you to look in a specific direction, With each laser pulse you will see flashes of light, and depending on the condition being treated the number of laser pulses varies.
Why is retina laser surgery used?
Retinal laser surgery can be used to treat many common diseases of the retina, on top of which is diabetic retinopathy. Diabetes is one of the most common chronic diseases that cause eye damage. In fact, the uncontrolled level of glucose in the blood can affect one way or another. Another on the retina and cause the growth of abnormal tissues and blood vessels in the eye, and these blood vessels can cause oozing or bleeding and swelling of the eye and thus damage to the retina.
In the process of treating the retina using a laser, laser energy and photocoagulation are used to destroy blood vessels and abnormal tissues, as laser beams are directed at them, causing their contraction, and this procedure can also be used to get rid of fluid accumulated in the macular area.
Some other pathological conditions can resort to retinal laser surgery as a method of treatment for these cases based on the doctor’s nomination and the nature of the patient’s condition, and the most prominent of these cases are the following:
Macular degeneration, which can occur with age and is a disease that causes poor central vision
Blockage of the veins in the retina
Retinal detachment, which is a condition in which the retina moves away from its normal position and is an emergency.
What is done before retinal laser surgery?
Before the doctor determines the appropriate treatment method for what the patient of retina suffers from, the correct diagnosis of the patient’s condition must first be done through conducting some preliminary examinations and eye examinations, where the doctor begins by taking the patient’s medical history and knowing whether he suffers from one of the two types of diabetes, What is the drug history also and the family medical history, then after that he begins to take eye measurements through some diagnostic tools where he will test:
Visual acuity, central and peripheral vision
Examination of the inner eye and determination of any abnormal tissues or blood vessels
Eye fluid pressure test
And other tests, and sometimes, especially in cases of retinal detachment, the doctor may request an ultrasound.
After the operation; What are the procedures followed?
After the laser photocoagulation process, the patient will need someone to take him home, so this must be arranged by her. You may suffer from the blurring of vision due to the drops that were applied to dilate the pupils, these drops cause light sensitivity, the patient may also see Floaters in the field of vision, but they disappear quickly the next day and the patient begins his normal life.
What are the expected results of retina laser surgery?
The laser retina operation has proven a great success for diabetic retinopathy and retinal detachment patients. There are some patients who may need to undergo another operation, but nevertheless, vision improves dramatically after a not-so-long period.
