Viscoelastic levitation of posteriorly dislocated intraocular lenses from the anterior vitreous.

In 5 consecutive cases presenting between 2000 and 2001, Viscoat injected via a pars plana sclerotomy was used to support and levitate 5 posteriorly dislocated IOLs into the pupillary plane. All 5 IOLs had dislocated into the anterior vitreous. This technique permitted successful exchange or suture refixation of the dislocated IOLs through limbal incisions in all cases. Diabetic macular edema accounted for a visual acuity of 20/60 in 1 patient. In the other patients, there were no significant corneal or retinal complications from the surgery and each regained a best corrected visual acuity of 20/40 or better.
