Structural effects on custom, flexible iris prostheses passing through injector systems.

Any of the seven injection systems tested in this study can be used effectively for fiber free artificial irises. Caution should be taken to ensure that control of insertion is maintained throughout the injection process. Screw-type injectors required less effort and yielded more control than plunger type injector. Fiber meshwork-containing artificial irises should not be inserted through an injector.
