Implantation of Scleral-sutured Posterior Chamber Intraocular Lenses During Penetrating Keratoplasty

Abstract

PURPOSE: To evaluate the clinical outcome in 29 patients (29 eyes) who underwent penetrating keratoplasty and scleral-fixation of an intraocular lens. METHODS: The indications for penetrating keratoplasty with scleral-fixation of an intraocular lens were anterior chamber pseudophakic corneal edema, aphakic corneal edema, trauma, and corneal scars. Patients with pseudophakic corneal edema underwent IOL exchange and penetrating keratoplasty and patients with lens subluxation underwent cataract extraction and penetrating keratoplasty in the same operation session. RESULTS: Preoperative spectacle-corrected visual acuity was hand motion in 13 eyes (44.8%) and 20/400 in 18 eyes (61.5%). Postoperative spectacle-corrected visual acuity of 20/400 or better was observed in 25 eyes (86.2%). At last follow-up, 26 corneal grafts (89.7%) remained clear. Three grafts (10.3%) failed, two because of glaucoma and one because of endophthalmitis. Glaucoma was observed in 7 eyes. CONCLUSION: Trans-scleral fixation of intraocular lenses combined with penetrating keratoplasty was a useful surgical technique in eyes with keratopathy and lacking posterior capsular support.
