Methods: This was a retrospective non -comparative study of six eyes in five patients with iris defects. The causes o f such defects included congenital aniridia, traumatic aniridia, and oculocutane ous albinism. Three eyes underwent primary implantations of a black diaphragm IO L, and three eyes were given secondary implantations. The visual acuity, subject ive severity of glare, postoperative anatomical outcome and any intraoperative o r postoperative complications were reviewed. Results: The mean follow-up period was 20.6 months (range 3-29 months. All patients showed stable or improvement in best-corrected visual acuity postoperatively. Glare and photophobia had impr oved subjectively in all patients after implantation of the black diaphragm IOL. Intraoperative complication included one case of hyphaema and iris damage durin g insertion of the IOL. Postoperative complications included intraocular inflamm ation with choroidal detachment, secondary glaucoma, and persistent epithelial d efect after surgery. None of the patients developed decentration of IOL after su rgery. Conclusion: The black diaphragm aniridia IOL is useful in the management of the condition in patients with iris deficiency including oculocutaneous albin ism. Intraoperative and postoperative complications are not uncommon, and patients should be monitored carefully in the perioperative period.展开更多

We report on contact lens fitting for visual rehabilitation in patient s after open globe injury. Patients: From 2000 to 2003, contact lenses were fitt ed unilaterally for the visual rehabilitation in 13 patients after open globe in jury. In three patients we found unilateral aphakia, in 8 patients a high or irr egular astigmatism after penetrating or autorotation keratoplasty and in two pat ients a traumatic aniridia, in one case combined with aphakia. Results: 11 rigid contact lenses were fitted with different designs of the front and back surface as well as two iris-print lenses. In 11 patients (86%) a good visual rehabili tation was achieved with an increase of visual acuity up to 9 lines while obtain ing a good contact lens tolerance. One patient wearing an iris-print contact le ns was unable to tolerate the contact lens due to its thickness and its weight. In another patient fitting of a contact lens was not possible because of the com plicated corneal condition. We did not observed severe contact lens complication s at any time. Conclusions: In addition to operative procedures for visual rehab ilitation after open globe injuries, the use of contact lenses is another possib le procedure for refractive correction. Different problems such as ametropia fol lowing aphakia, irregular or high astigmatism or aniridia can be solved with goo d visual results, good tolerance and less complications.展开更多
