Histologic study of eyes with transsclerally sutured posterior chamber intraocular lenses.
We studied the postmortem histologic characteristics of two eyes that had undergone penetrating keratoplasty and transscleral suturing of a posterior chamber intraocular lens for bullous keratopathy. The eyes were studied three days postoperatively in a 79-year-old man with pseudophakia and six months postoperatively in an 83-year-old man with aphakia. We also removed a posterior chamber intraocular lens in a 73-year-old woman who had an epithelial downgrowth three months postoperatively. In the first two cases, only one of four haptics was successfully positioned in the sulcus. Histologic study disclosed a thin fibrous capsule surrounding the haptics at their attachment site, no inflammation around the transscleral portion of the suture, and exposure of a suture tip externally. In the third case, the intraocular lens fell back into the vitreous cavity after the fixation sutures were cut externally at the time of surgical removal. Stability of the lens in all three cases was primarily a result of intact transcleral sutures and not fibrous encapsulation or ciliary sulcus placement of haptics.
