How are eye floaters treated? Most people over the age of 50 have floaters, which rarely impair vision, but they occasionally become so dense that they require medical intervention. The practitioner will perform a vitrectomy, removing the vitreous humor and its debris from the eye and replacing it with a salt solution to help the eye retain its shape. Around 225,000 vitrectomies are performed every year in the United States, and recovery time lasts between four and six weeks. Physicians don’t condone the treatment, saying its surgical danger far outweighs its benefits.
