What's This? By David Douglas

NEW YORK (Reuters Health) - Implantation of a Cionni ring and an intraocular lens appears to be a generally successful means of dealing with eyes with a subluxated lens associated with Marfan's syndrome, according to Canadian researchers.

"It seems that the use of the Cionni ring in these difficult cases makes it possible to remove the lens and stabilize an intraocular lens in the majority of cases," senior investigator Dr. David Rootman told Reuters Health. "This may lead to a lower incidence of long-term serious complications in these difficult cases -- compared with older studies."

In the November issue of the British Journal of Ophthalmology, Dr. Rootman at Toronto Western Hospital and colleagues report on a case series of 15 eyes in 12 patients aged 19 to 56 years.

A 2-eyelet Cionni ring and an AcrySof (Alcon) foldable intraocular lens (IOL) were implanted in 13 eyes. Two eyes had trans-scleral IOL fixation in the ciliary sulcus. Capsular bag centration was deemed excellent in all eyes and visual acuity improved to better than 20/40.

At a mean follow-up of 14 months, the most frequent postoperative complication was posterior capsule opacification, which was seen in three eyes. Neodymium:YAG posterior capsulotomy was required in two. There were no retinal detachments.

With the procedure, concluded Dr. Rootman, "vision can often be improved to the level where these young patients may be able to obtain drivers' permits and function more normally."
