Objective: Major defects in the lower half of the iris are difficult to treat by suturing. Iris prostheses can be used in this situation. Most iris prostheses are not suitable or are poorly suitable in phakic eyes.
Methods: Experimental study in the phakic human donor eye using a new iris-fixed and sulcus-supported iris prosthesis.
Results: In collaboration with the Ophtec company, an iris prosthesis was developed, which can be fixed to the iris and which is stabilised by a frame that has to be placed in the sulcus. This prosthesis was implanted in a phakic human donor eye with an iatrogenic defect in the lower half of the iris for 3 hours. The correct position of the prosthesis frame in the sulcus was examined by means of both UBM and Apple-Miyake view.
Conclusions: The new iris-fixed and sulcus-supported prosthesis, when used in the phakic human donor eye, was in correct position with complete cover of the iris defect. However, there is no experience so far of use in patients.
