Cataract extraction in a fur seal.
Cataracts are common in pinnipeds, but ocular examination and surgery are complicated because of the small pupil, which is difficult to dilate with mydriatics. Vision was evident after a cataract was removed from a fur seal, using a manual technique of irrigation and aspiration. Access to the lens was limited by the constricted pupil, which could not be dilated with tropicamide, phenylephrine, or atropine.
