I have done laser treatment of vitreous floaters nearly every day, frequently more than once a day, for 18 years with zero complications.  This very high level of safety is the justification for doing this procedure on a patient's only eye.  I have done about 150 patients with only one functioning eye.  Vitrectomy (sucking and cutting all the vitreous out of the eye) (the only other effective treatment) is essentially never done on an only eye because of its high complication rate.)           

            A 35 year old male with high myopia said that four years ago he developed a vitreous floater in his right eye that was associated with a retinal detachment.  He had retinal detachment surgery and then had a vitrectomy and eventually had to have the right eye removed.   He reported that two months prior to seeing me he developed a very large vitreous floater in his only remaining eye (see left photo).   He saw a retinal surgeon who treated retinal degeneration in that eye.  Because of the vitreous floater, he could no longer work as an engineer, and he felt he could no longer go through life as is.   He had been unable to find a doctor who would perform a vitrectomy on his remaining eye because he had to have his other eye removed after vitrectomy.  I examined him and told him that I could help him.  Both he and his mother started crying.  He wasn’t very well dilated, so I put in more drops and went for a very short lunch.  When I returned, my receptionist said, “That patient and his mother have cried the whole time you were gone.  Are they all right?”  I said, “They are just happy.”  Because of the safety of laser treatment, I was able in a few minutes to completely remove the large Weiss ring with spreading borders from his only eye (see right photo).
