How are intraocular injections performed?
- Topical anesthetic is applied directly to the eye
- The eye is rinsed with an iodine solution to reduce the risk of infections.
- NOTIFY YOUR DOCTOR IF YOU HAVE AN ALLERGY TO IODINE AND SHELL FISH
- Your doctor will allow approximately 5 minutes for the anesthetic and iodine solution to take full effect.
- The injection is given using a very fine needle just outside the pupil.
Do intraocular injections hurt?
Most patients have little to no discomfort during the procedure. Some patient do report slight burning sensation when anesthetic is applied. A slight pressure sensation can be felt at the time of the injection.
Are there side effects to the intraocular injections?
Intraocular injections are generally safe procedures. Occasionally side effects do occur. Corneal abrasion, a slight scratch on the surface of the eye, and rarely infections do occur. Systemic side effects are rare since only a minute amount of drug is used. Discuss with your doctor regarding the potential systemic side effects of each drug.
