Phacoemulsification with implantation of Morcher aniridia capsular rings for postoperative atonic pupil after iridencleisis--case report.

Introducion: Large iris defets, anirdia or wide atonic pupil may cause disturbing photoptic phenomena my require surgical treatment. In acquired iris defects, ophthalmologists have a relatively wide choice of therapeutic strategies, which depend on the size and etiology of the defect and the comorbidities. The goal of treatment is to restore iris diaphragm and to reconstruct the pupil in order to prevent glare and to increase the quality of perceived image.
Case Report: We present a case of cataract and unilateral wide, atonic pupil in a patient 39 years after iridencleisis, who complained of intense glare in the left eye and photophobia ever since. The patient was successfully treated by phacoemulsification through a 2.75 mm clear corneal incision with implantation of two black Morcher aniridia capsular rings. The patient experienced a significant improvement in her subjective quality of vision and a constant glare that she had been experiencing for years resolved.
Conclusion: The presented case indicates that Morcher aniridia capsular rings may be a good tool instrument to assist the surgeon in cases of cataract concomitant with wide and atonic pupil. Using these rings reduces glare and improves the subjective quality of patients' vision.
