Abstract

BackgroundThe ideal intraocular lens in cases of aphakia without capsular support is debated. Choices include anterior chamber lenses, iris- or scleral-sutured lenses, and iris-claw lenses. Our aim was to report our long-term evaluation of the use of retropupillary implantation of the Artisan iris-claw intraocular lens RPICIOL in several aphakic conditions without capsular support.

MethodsA retrospective analysis of consecutive 320 eyes of 320 patients 222 males and 98 females without capsular support in which we performed RPICIOL implantation in post-traumatic aphakia 141 eyes, group 1, post-cataract surgery aphakia 122 eyes, group 2, and in cases in which penetrating keratoplasty was associated with vitrectomy 57 eyes, group 3. Either anterior or posterior vitrectomy procedures were performed with 20–, 23-, or 25-gauge techniques for different associated anterior or posterior segment indications. We reviewed the refractive outcome, anatomical outcome, long-term stability of the implants, and possible long-term complications.

ResultsThe mean patient age was 59.7 years range, 16–84 years in group 1; 60.1 years range, 14–76 years in group 2; and 65.8 years range, 25–71.5 years in group 3. The mean follow-up time was 5.3 years range, 1 month to 8 years. At the end of the follow-up period, the mean post-operative best-corrected LogMAR visual acuity was 0.6 range, perception of light to 0.3 in group 1; 0.3 range, 0.5–0.1 in group 2; and 0.6 range, hand movement to 0.2 in group 3. Disenclavation of RPICIOLs occurred in three cases because of slippage of one of the iris-claw haptics and spontaneous complete posterior dislocation occurred in one case. One case presented with retinal detachment, and no cases of uveitis were observed. Eight cases complained of chronic dull pain, and severe iridodonesis was seen in five cases. One case of post-operative macular edema was observed without post-operative increase in the mean intraocular pressure. There was no statistically different change in the endothelial cell density cells-mm at the end of the follow-up period.

ConclusionsRPICIOL for secondary implantations is a valid alternative strategy to scleral-fixated or angle-supported IOL implantation.
