The xenon arc photocoagulator can be used effectively for alteration of the size, shape, and position of the pupil. Enlargement and/or centralization of the pupil often provides significant improvement in vision. The best candidates are aphakic patients who have had round pupil cataract extraction and are on miotic therapy. Nineteen cases are described in which photocoagulation coreplasty was performed. The results have been gratifying. It would seem that this procedure could be much more widely applied than it is at the present time.
