چکیده
purpose : to evaluate the outcome of iris-claw phakic intraocular lens (piol) implantation for high myopia in a subspecialty training setting methods : iris-claw phakic artisan (ophtec b.v., groningen , the netherlands) intraocular lens implanted patients were invited for an evaluation visit: 83 eyes had been operated on by a group of 10 cornea fellows under the supervision of nine anterior segment faculty members during 2005-2006. postoperative time course ranged from four to 38 months. the outcome was assessed in those who participated in the evaluation visit (50 eyes collectively). results : evaluation visit uncorrected visual acuity (ucva) was equal to or better than preoperative best spectacle corrected visual acuity (bscva) in 68% of the eyes mean bscva had improved significantly (equivalent to two snellen lines p<0.004). residual spherical equivalent (se) was within ±1.00 diopter (d) in 68% and ±2.00 d in 92% eyes with longer postoperative time courses (>10 months) were on average 0.94 d more myopic (p=0.007). no eye had lost bscva. no major complication like retinal detachment or cataract had happened. better ucva was predictable by shorter postoperative time course, milder baseline myopia, and better baseline bscva (p<0.004). conclusion : iris-claw piol implantation for high myopia was found efficacious and safe in subspecialty training. a noticeable myopic drift was observed, and refractive predictability was not as favorable as expected. induced astigmatism, miscalculation, mislabeling/wrong refraction, and myopic progression could have been responsible for >2.00 d residual se in four eyes. iranian journal of ophthalmology 200921(3):21-28 © 2009 by the iranian society of ophthalmology

OBJECTIVE To evaluate the efficacy, safety and stability of posterior chamber phakic intraocular lens (PIOLs) implantation for the correction of high myopia. METHODS Thirty-nine eyes of twenty patients with high myopia (between -11.75 and -25.75 diopters) had a posterior chamber PIOL (Staar ICL) implanted.

We report the refractive correction of high myopia in a 23-year-old patient with idiopathic microspherophakia using iris-fixated phakic intraocular lenses (pIOLs) (Verisyse/Artisan). Four years after bilateral implantation, the uncorrected distance visual acuity was 20/25 with a correction of 20/20(-1) in both eyes. No intraoperative or postoperative complications occurred. Iris-fixated pIOLs a...

This study is a meta-analysis comparing the efficacy, predictability, and safety of correcting myopia via implantation of two types of phakic intraocular lens (PIOLs): the implantable collamer lens (ICL) and iris-fixed PIOL. The Cochrane library, Pubmed, and EMBASE were searched. Study selection, data exclusion, and quality assessment were performed by two independent observers. The pooled rela...
