Staining of zonules during posterior chamber lens implantation in a cadaver eye model.

A cadaver eye model was used to study the effects of extracapsular lens removal and implantation on the zonules and capsule. Five staining solutions were instilled in the posterior and anterior chambers of human cadaver eyes and washed out three to five minutes later. Gomori's chrom hematoxylin-eosin most clearly revealed the zonules. Three eyes stained in this way had lens removal (including the continuous circular capsulorhexis technique for anterior capsulectomy) and intraocular lens implantation. The effects of the surgery on the zonules and capsule were clearly visualized and appeared quite satisfactory. This staining technique may prove useful in other cadaver eye models.
