Methods: Nine patients with traumatic iris defects, congenital aniridia or iris coloboma, and surgical or o ptical iridectomies were included in a noncomparative case series. Cataract surg ery with intraocular lens and prosthetic iris implantation was performed in 10 e yes. The visual acuity, subjective degree of glare disability, postoperative ana tomic results, and intraoperative and postoperative complications were evaluated . Results: The mean follow-up was 17.75 months (range 4-48 months). Best-corr ected visual acuity improved in nine of 10 eyes (90%) and remained unchanged in one eye. Glare subjectively improved in four of five eyes (80%) of patients co mplaining of glare preoperatively. All eyes achieved the desired anatomic result . Intraoperative complications included one anterior capsular tear. Postoperativ e complications included a short period of mild postoperative anterior uveitis in four eyes. Secondary glaucoma was absent. Conclusion: In patients w ith iris deficiency, implantation of prosthetic iris device, and intraocular len s implant following cataract surgery appears to be safe and effective in reducin g glare disability and improving visual outcomes.展开更多

DESIGN: Interventional case report. METHODS: Two patient s with uveal melanoma and secondary glaucoma were treated by enucleation. A larg e surface area (70 mm2), spatulated, end-freezing cryotherapy probe (“Finger- tip”probes, MIRA, Inc.) was used to induce proptosis during optic nerve transse ction. RESULTS: This new probe offers homogeneous freezing over a relatively lar ge surface area. This new cryoprobe was used to create a large cryo-adhesion on the cornea, for an excellent purchase of the eye during enucleation surgery. Us ing this adhesion, the eye was lifted, enabling transsection of the optic nerve. CONCLUSIONS: This report includes photographs of the cryoprobe, the corneal cry o-adhesion, and describes its use for traction during enucleation surgery.展开更多
