BACKGROUND: Intraocular lens implantation in eyes with pseudophakic or aphakic corneal edema and insufficient posterior capsular support presents a surgical challenge. The iris claw lens has the advantage that it can be fixated to the iris without sutures because the peripheral iris is incarcerated between the claws. METHODS: We present the results of a study with implantation of an iris claw lens in combination with penetrating keratoplasty in 19 eyes of 19 patients with pseudophakic or aphakic corneal edema which lacked posterior capsular support. The lens was fixated on the anterior iris surface (12 eyes) or posterior iris surface (seven eyes). RESULTS: Mean follow-up time was 11.8 months (7 to 21 months). All grafts remained clear. One patient was lost for follow up after 3 months. Visual acuity improved in 83% of the patients. Twenty-eight percent of the patients had a visual acuity of > or = 20/40. Complications such as pigment dispersion, glaucoma, peripheral synechiae, and lens decentration were rare. CONCLUSIONS: We feel iris claw lens implantation combined with penetrating keratoplasty is a safe alternative to achieve pseudophakia in eyes with corneal edema and inadequate posterior capsular support.
