This condition can pose several problems in a young person, and I would like to report the treatment of one such case.

The patient complained of glare and blurring of vision, although his pinhole visual acuity was 6/9. We fitted him with a shell contact lens with the iris pattern (similar to the other eye) painted onto the lens,
