Abstract

The authors describe "iris-assisted," open-sky, continuous curvilinear capsulorhexis (CCC) in a triple procedure combining corneal transplantation, cataract extraction, and intraocular lens implantation. They do not use miotics or mydriatics. Patients receive oral acetazolamide (250 mg), intravenous mannitol (5 mL/kg), and Honan balloon at 30 mm Hg for 20 to 30 minutes before surgery. After trephination and excision of recipient cornea, the pupil assumes a mid-dilated position. After injection of 2.3% hyaluronic acid into the anterior chamber, a central linear incision is made in the anterior capsule using a cystotome needle and a CCC is made (approximately 5.5 mm) along the pupillary margin with CCC forceps. The mid-dilated iris can "assist" by resisting posterior pressure to reduce the risk of capsular extension. The nucleus passes through the capsulorhexis following hydrodissection. The keratoplasty is completed followed by cortex removal and in-the-bag intraocular lens implantation, which are facilitated by the CCC in a closed system.
