PURPOSE To objectively compare the optical quality and the intraocular scattering after implantation of the posterior chamber phakic implantable collamer lens (Visian ICL™, STAAR Surgical) with and without a central artificial hole for moderate to high ametropia. METHODS This retrospective study comprised 28 eyes of 28 consecutive patients undergoing Hole ICL implantation (mean age ± standard...

AIMS To report the results of a series of patients who were treated with LASIK to correct post penetrating keratoplasty ametropia. METHODS 26 eyes of 24 patients underwent LASIK to correct astigmatism and myopia after corneal transplantation; 14 eyes also received arcuate cuts in the stromal bed at the time of surgery. The mean preoperative spherical equivalent was -5.20D and the mean preoper...

INTRODUCTION This article aims to evaluate the role of phakic intraocular lens (pIOL) implants in the treatment of high-refractive errors and amblyopia in the pediatric setting. METHODS A literature search of the PubMed database was conducted in December 2012 using the keywords: pIOL implants, amblyopia, pediatric refractive surgery and ametropia, and articles of high or medium clinical relev...

PURPOSE To evaluate the 3-year safety, efficacy, predictability, and stability of iris-fixated toric phakic intraocular lens (pIOL) implantation for the correction of myopia or hyperopia with astigmatism. SETTING Department of Ophthalmology, Johannes Gutenberg University, Mainz, and Department of Ophthalmology, University Clinic, Bochum, Germany. METHODS A prospective clinical trial of 40 e...

PURPOSE To investigate visual function and ocular features in children with attention deficit hyperactivity disorder (ADHD). METHODS Fifty-one children underwent a detailed ophthalmologic evaluation. Thirty-two were diagnosed with ADHD, and 19 children with attention deficit disorder (ADD). The mean age was 9.9±3.1 years. RESULTS The average best-corrected visual acuity of the better-seeing...

PURPOSE To evaluate the safety and efficacy of customized transepithelial photorefractive keratectomy (PRK) for the correction of iatrogenic ametropia after penetrating keratoplasty (PKP) or deep lamellar keratoplasty. SETTING Eye Clinic, Department of Neurological and Visual Sciences, University of Verona, Verona, Italy. METHODS This study comprised 9 patients who had irregular astigmatism...

BACKGROUND To report the clinical outcomes of correcting pseudophakic ametropia using toric implantable collamer lens with a 360 um central hole (TICL V4c). CASE PRESENTATION The right eye of a 22-year-old male patient developed high myopia after unilateral phacoemulsification and intraocular lens (IOL) implantation following traumatic cataract 16 years ago. The manifest refraction was -11.50...

Implantation of intraocular lens with Iris-fixation is a safe, efficient and predictable surgical procedure, which empowers the refractive surgeon with singular capabilities. Among their advantages are the reversibility, preservation of accommodation and a broad spectrum of ametropic correction. This lens also appears to be a valid option, with a favorable complication rate, for the treatment o...
