Management of the dislocated crystalline lens with a perfluorocarbon liquid.

Vitreoretinal surgery allows the effective removal of soft to moderately dense crystalline lens fragments, using the vitrectomy probe and the ultrasonic fragmentation probe. Hard lenses cannot be removed with these instruments. Previously described techniques for removal of hard lenses include trapping the lens anteriorly with needles, cryoextraction of the lens in an air-filled eye, and manipulation with sodium hyaluronate. These methods are difficult and dangerous in some cases. We used perfluorocarbon liquid to facilitate the safe removal of a surgically luxated hard crystalline lens. Injection of the perfluorocarbon liquid floated the lens off the retinal surface and into the anterior vitreous cavity. In this location, the lens was delivered by using standard extracapsular cataract extraction techniques. This technique allowed removal of the hard crystalline lens with minimal manipulation, and was helpful in the setting of poor media clarity.
