Abstract Details

Purpose:

To evaluate the safety and efficacy of Morcher 50F iris diaphragm implantation for managing moderate to large defects of the human iris at the time of cataract surgery

Setting:

Stein Eye Institute, UCLA, Los Angeles, California, USA

Methods:

Demographic, preoperative, and postoperative data of subjects implanted with Morcher 50F modified capsule tension rings and followed to 1 year were reviewed. Safety measures included loss of corrected distance visual acuity (CDVA), surgical complications, adverse events, and secondary surgical interventions. Efficacy measures included corrected distance glare visual acuity (CDGVA), daytime and nighttime glare symptom scores, and subjective cosmesis scores.

Results:

Twelve subjects were implanted. Median CDVA was 20/70 before surgery and 20/20 after surgery. There were no lost lines of CDVA and no intraoperative complications. The most common postoperative complication was posterior capsule opacification. Two adverse events were unrelated to the Morcher 50F device. Four patients experienced secondary surgical interventions, the most common of which was laser capsulotomy. Median CDGVA improved from <20/400 before surgery to 20/50 after surgery. One subject worsened. The median subjective daytime glare symptom score improved from 9 to 3 on a 10-point scale (p=0.001). The median nighttime subjective glare symptom score improved from 8 to 2 (p=0.001). The subjective cosmetic appearance of the eye stayed the same or improved for all subjects (p=0.031).

Conclusions:

Morcher 50F iris diaphragm implantation is relatively safe and effective at reducing light and glare sensitivity in eyes with iris defects when combined with cataract extraction and intraocular lens (IOL) implantation.
