In patients with diabetic retinopathy, it usually takes 4-5 sessions of total retinal laser photocoagulation, with an interval of time after each laser shot, usually about a week. However, the interval varies for each patient’s condition. After each treatment, it is important to follow the doctor’s instructions for regular follow-ups, and the doctor will advise when the next laser will be given, depending on the patient’s recovery. It is important to emphasize that some patients feel that their eyes are recovering well, so they do not come for follow-ups, which is very dangerous. This is because there are some changes in the condition that are not obvious to the patient, so it is important to detect them as early as possible through the review and treat them as early as possible when the condition has not progressed to the point of no return, so that the chances of preserving the vision and the eye are much better. After each laser, the eyes do not need to be covered, but you should try to avoid rubbing your eyes as hard as possible. Because the eye is anesthetized during laser treatment, the pain in the eye disappears temporarily, and the patient feels no pain even when rubbing the eye hard enough to cause corneal abrasions. In addition, because the laser requires a dilated pupil, the patient’s vision will be blurred when the laser is first applied, but will recover in 5-6 hours. Other than that, there is no need to pay special attention to diet and exercise, just use your eyes normally and pay attention to prevent eye trauma.
