Hi, I had gone through your query and understood your concerns. Intravitreal anti-VEGF injections are often used to improve the vision of people with diabetic retinopathy. Intravitreal anti-VEGF injections are given by an ophthalmologist on an outpatient basis. A few days before the procedure, you will be given antibiotic eye drops to help prevent infection. You should notice an improvement in your vision one month after the injection. However, it is recommended that further injections are given at one-month intervals until there is no further improvement to your vision for three consecutive months. At this point, treatment should be stopped. Your eyes will need to be checked regularly to assess whether further treatment is required. Hope this guides you. Thank you.
