Abstract Details

Purpose:

To evaluate intraoperative complications of cataract surgery with endocapsular iris implants for eyes with congenital aniridia.

Setting:

Kyorin Eye Center, Kyorin University School of Medicine, Mitaka, Tokyo, Japan

Methods:

Case reports of 4 eyes of 2 patients who underwent cataract surgery combined with insertion of endocapsular iris implants. Case 1 was a 24-year old man who underwent surgery on May 2004 and case 2 was a 58-year old woman who underwent surgery on February 2009. They were parent and son and two other sons of case 2 had congenital aniridia.

Results:

In preoperative findings of case 1, bilateral cortical and zonular cataract, nystagmus, and macular hypoplasia and exotropia in the right eye were found. In case 2, cortical cataract of grade 3 nuclear sclerosis in the right eye and cortical cataract of grade 3 nuclear sclerosis with fibrous anterior subcapsular cataract in the left eye were detected. Under retrobulbar anesthesia, phacoemulsification and intraocular lens implantation combined with insertion of aniridia rings implants (50C and 50D, Morcher GmbH, Stuttgart, Germany) were performed in all eyes. Continuous curvilinear capsulorhexis was completed in all eyes although the anterior lens capsule was very thin and weak. Trypan blue dye to improve visualization of anterior capsule was injected in one eye of case 2. Posterior capsule rupture extended from anterior capsule tear occurred in one eye of case 1 when second iris implant was dialed into capsular bag. However, intraocular lens and iris implants were successfully implanted in the lens capsule in all eyes.

Conclusions:

Lens capsule tear may develop in eyes with congenital aniridia because of multiple implants into the weak lens capsule. Complications during cataract surgery with iris implants for eyes with congenital aniridia caused by weak lens capsule should be carefully managed. FINANCIAL DISCLOSURE?: No
