title: Posterior chamber IOL implantation during keratoplasty for aphakic or pseudophakic corneal edema.
abstract: Because of their many advantages, posterior chamber (PC) intraocular lenses (IOLs) were sutured to the posterior iris (in the absence of a lens capsule) in combination with penetrating keratoplasty for aphakic and pseudophakic corneal edema in 53 cases. Secondary PC IOL implantations were performed in aphakic corneal edema (nine cases), and IOLs were exchanged for PC IOLs in pseudophakic corneal edema (44 cases). Ninety-six percent of the grafts remained clear. Forty-three percent of the eyes had 20/40 or better visual acuity, 38% between 20/50 and 20/200, and 19% worse than 20/200, with an average follow-up time of 6.4 (range 3-13) months. The most common cause of poor vision was cystoid macular edema present preoperatively in 20 eyes and postoperatively in 22 eyes. Other causes of persistent visual impairment included macular degeneration (five cases), retinal detachment (two cases), preoperative glaucoma damage (one case), severe postoperative glaucoma damage (one case), endophthalmitis (one case), and graft rejection (one case). Our short-term results indicate that this procedure may be a viable alternative to the use of secondary anterior chamber IOL implantation during penetrating keratoplasty.
