An instrument to aid intracapsular cataract extraction of dislocated lenses.
Techniques for surgical removal of a dislocated lens have evolved considerably in the past 30 years. There has been a change in preference from open-sky techniques to the use of automated vitrectomy instruments. We introduce an instrument which may be useful in selected patients with dislocated lenses. This instrument is placed through the pars plana to entrap the lens anteriorly without trauma to the retina or ciliary body. Cryoextraction of the lens through a limbal incision is then performed. We feel this instrument will be most useful in the management of a dislocated nucleosclerotic lens.
