Abstract/OtherAbstract:
Background:  To assess outcomes of the iris claw intraocular lens implanted in the retropupillary position for correction of aphakia without adequate capsular support. Design:   Retrospective study of patients consulted at two private practices and a tertiary public hospital clinic in Brisbane, Queensland. Samples:   32 consecutive patients who underwent posterior chamber insertion of the iris claw intraocular lens alone or in combination with other procedure/s by the same consultant ophthalmologist (GL). Methods:  Lens power was calculated using an A-constant of 117.0. Main Outcome Measures:  Clinical examination Results:  34 eyes in 32 patients (23 male, 9 female) were included in the study. Indications for surgery were pseudophakic bullous keratopathy (n=14), aphakia from previous lens extraction/lensectomy (n=9), subluxation of intraocular lens (n=7), cataract extraction (n=2), explantation of anterior chamber intraocular lens due to uveitis (n=1) and for Baerveldt tube insertion (n=1). Follow-up duration ranged from 1 to 68 months. Of the 26 eyes followed for at least 6 months, the final vision improved in 69% (n=18), remained unchanged in 8% (n=2) and worsened in 23% (n=6). Final visual acuity was 6/12 or better in 58% (n=15). Complications included iris trauma/defect (n=8), pupil irregularity/ovalisation (n=6), microhyphaema (n=2) and lens decentration (n=2). Conclusion:  Implantation of the iris claw intraocular lens in the retropupillary position is a useful technique for correction of aphakic eyes with sufficient iris support, avoiding the corneal complications of an anterior chamber intraocular lens and the surgical challenge of a sutured posterior chamber intraocular lens. © 2012 The Authors.
