Visual outcomes following Artisan aphakia iris claw lens implantation

Abstract

Objective To assess the visual outcome of eyes undergoing Artisan lens implantation for aphakia, to identify reasons for poor outcomes, and to report incidences of post-operative uveitis, glaucoma, or hyphaema. Methods A retrospective analysis of 32 eyes rendered aphakic through various causes, which subsequently underwent Artisan lens implantation. Results A total of 32 eyes from 31 patients were reviewed. Follow-up ranged from 6 to 42 months, mean 17.3 months. The commonest cause of aphakia was following complicated phacoemulsification in 17 of the 32 eyes (53.1%). At final follow-up, 21 of the 32 eyes (65.6%) achieved best-corrected visual acuity (BCVA) better than that measured pre-operatively and 10 of the 32 eyes (31.3%) matched their pre-operative BCVA. Of 33 eyes, only 1 (0.03%) attained a final BCVA worse than pre-operatively, owing to non-arteritic anterior ischaemic optic neuropathy. A total of 4 of the 33 eyes (12.5%) had pre-existing glaucoma or ocular hypertension; no additional intraocular pressure problems were identified during the follow-up period. Conclusion This study suggests that Artisan iris claw lens insertion is beneficial in acquired aphakia, matching or exceeding pre-operative BCVA in the overwhelming majority of the cases. In addition, this series did not identify any post-operative problems with uveitis, glaucoma, or hyphaema.

Visual outcome and complications after posterior iris-claw aphakic intraocular lens implantation

“…This is comparable to the results in previous studies of PC iris-claw IOLs, 21 anterior-fixated iris-claw IOLs, 22,23 secondary open-loop AC IOLs (60% to 77% of eyes 11,24 ), secondary sulcus-sutured PC IOLs (53.8% to 77.8% 3,14 ), and secondary iris-sutured PC IOLs (60% to 67% 8,25 ).…”

“…Previous studies 11,18,22 found that secondary AC IOL implantation can result in severe endothelial cell loss and subsequent corneal decompensation. G€ uell et al 26 report a 7.78% cell loss within the first year and a 10.9% loss over the first 36 months after anterior-fixated aphakic Artisan IOL implantation, suggesting that most endothelial cell damage occurs intraoperatively.…”

Three-year follow-up of secondary anterior iris fixation of an aphakic intraocular lens to correct aphakia

“…The Artisan IOL (Ophtec BV), a poly(methyl methacrylate) (PMMA) iris-fixated IOL, has a better design than previous generations and has been successfully used to correct aphakia 5,[9][10][11][12][13] and high myopia 1,14,15 in many countries.…”
