Complications of Anterior Chamber Fixation of Posterior Chamber Intraocular Lenses

Arch Ophthalmol. 2006;124(4):606-607. doi:10.1001/archopht.124.4.606

We read with interest the article by Hara and Hara1 in the August 2004 issue of the ARCHIVES in which they describe long-term corneal endothelial cell loss in eyes in which posterior chamber lenses were implanted in the anterior chamber. In their series, no other sight-threatening complications were noted. However, we previously described a series of complications in 4 eyes of 3 patients who had undergone implantation of 3-piece C-loop posterior chamber lenses into the anterior chamber.2 With follow-up of 2 to 4½ years, all of the 4 eyes exhibited at least 4 of the following complications: (1) loop encapsulation by peripheral anterior synechiae; (2) recurrent iritis; (3) central loop displacement with corneal endothelial touch; (4) progressive endothelial cell loss and corneal edema; (5) glaucoma; and (6) cystoid macular edema. Intraocular lens removal was required in all of the 4 eyes, and penetrating keratoplasty was performed in 1 of them.
