Just to possibly clear up the discussion above, vitrectomy port insertion carries a smaller risk than ocular injections. Vitrectomy ports are sterilized 25g metal ports through which encased tools are inserted. Injection utilizes a hypodermic needle in a nonsurgical setting. If you research the topic, you'll find many surgeries carry less risk of your common bacteria infection than an office based injection.

Thanx for clearing up!!! But, then again we can use vitrectomy port insertion to inject enzymes or any other substance. That would reduce the risk. Wouldn't it? 

BTW Does anyone know if any research is currently going on Eye floaters? If so can u pls give me the link?
