PURPOSE To evaluate variations in the position of the phakic iris claw lens (Artisan, Verisyse) and the natural crystalline lens during the accommodation process. METHODS We measured changes in position of the iris claw lens and the crystalline lens during the accommodation using optical coherence biometry (AC Master/Carl Zeiss Meditec, Germany) in 17 patients (28 eyes) with a phakic iris cla...

purpose : to compare visual outcome of aspheric and spheric intraocular lenses (iols) implantation in patients with age-related cataract in terms of visual acuity (va), contrast sensitivity (cs) and spherical aberration methods : in this prospective randomized interventional study, 59 consecutive cases of senile cataract who had been admitted for cataract surgery to farabi eye hospital, tehran,...

PURPOSE To compare the measurement of anterior chamber depth exclusive of corneal thickness using Orbscan IIz and ultrasound biomicroscopy (UBM) and evaluate the repeatability of each method. METHODS Three consecutive measurements of anterior chamber depth were prospectively performed using Orbscan IIz and Paradigm 50-MHz UBM in 40 eyes in 20 individuals. Mean values were compared using the p...

PURPOSE To compare the effectiveness of toric foldable iris-fixated phakic intraocular lens (pIOL) implantation and non-toric foldable iris-fixated pIOL implantation with limbal relaxing incisions (LRIs) for correcting moderate-to-high astigmatism in myopic eyes. MATERIALS AND METHODS The medical records of 146 patients (195 eyes) with myopic astigmatism who underwent toric foldable iris-fixa...

A 27-year-old woman with bilateral high myopia had anterior chamber iris-claw phakic intraocular lens implantation in her left eye under local anesthesia and with no intraoperative complications. The preoperative slit-lamp examination was normal, and she had no relevant past medical history. On the second postoperative day, patient developed fixed, dilated mydriasis, and one month later, an IOL...

AIM To determine the efficacy and safety of keratorefractive surgery in patients with accommodative and non-accommodative strabismus in a prospective study. METHODS Preoperative assessment included uncorrected (UCVA) and best-corrected visual acuity (BCVA), manifest and cycloplegic refraction and orthoptic examination. Laser in situ keratomileusis, laser epithelial keratomileusis and Artisan ...

PURPOSE To evaluate changes in endothelial cell density (ECD) in the corneal region after implantation of an iris-fixated phakic intraocular lens (PIOL). METHODS Forty-five eyes of 25 myopic patients implanted with Artisan iris-fixated PIOLs (Ophtec BV) and 30 eyes of 15 myopic controls were enrolled. Corneal ECD and the distance between endothelium and the PIOL optic were evaluated in five d...

PURPOSE To evaluate the change of accommodation-convergence parameters after implantation of Artisan phakic intraocular lens (PIOL). METHODS Prospective study for the patients with the Artisan PIOL implantation was performed. A total of 37 patients (3 males and 34 females) enrolled the study. Preoperatively, convergence amplitude, the stimulus accommodative convergence per unit of accommodati...
