Experiences with the Boberg Ans lens and sodium hyaluronate (Healonid).

The mean central endothelial cell loss arising with the availability of Sodium hyaluronate (Healonid), from insertion of a Boberg Ans implant was 14 per cent following extracapsular cataract extraction and 16 per cent following intracapsular surgery. These figures compare favourably with those described by other authors following simple intracapsular extraction without lens implantation and the closed chamber techniques demonstrated should be regarded as safe in so far as they virtually eliminate the incidence of late corneal dystrophy as a complication of lens implantation.
