PURPOSE We report the postoperative results of the Artisan Hyperopia phakic intraocular lens (IOL; model 203W; Ophtec, Groningen, The Netherlands). DESIGN Prospective, nonrandomized trial. PARTICIPANTS Twenty-six eyes of 13 self-selected patients with refractive error ranging from +3.00 to +11.00 diopters (D). INTERVENTION Patients with hypermetropia were implanted with the Artisan Hypero...

The purpose of this paper is to consider the long-term results of the iris clip lens in senile aphakia. It is not intended to discuss the many different forms of intraocular lens implants. Ophthalmic surgeons are well aware of the discouraging shortand long-term failure rate when contact lenses are used to correct aphakia, and this has stimulated renewed interest in intraocular lens implants in...

This study aimed to investigate the effect of myopic defocus on visual acuity after phakic intraocular lens (IOL) implantation and wavefront-guided laser in situ keratomileusis (wfg-LASIK). Our prospective study comprised thirty eyes undergoing posterior chamber phakic IOL implantation and 30 eyes undergoing wfg-LASIK. We randomly measured visual acuity under myopic defocus after cycloplegic an...

PURPOSE To examine lateral and axial positioning of phakic intraocular lenses (IOLs) with iris fixation in the anterior chamber and to examine short-term stability of the IOL position. SETTING The Netherlands Opthalmic Research Institute, Amsterdam, the Netherlands. METHODS Thirty patients participated in the study. Thirty-one eyes were implanted with the 204 type myopia IOL, 14 eyes with t...

PURPOSE To assess the Artisan intraocular lens to correct myopia in phakic eyes. SETTING European multicenter study sponsored by Ophtec BV, Groningen, The Netherlands. METHODS In this prospective multicenter clinical study, the Artisan lens was implanted in 518 eyes between September 1991 and October 1999. The power of the lenses ranged from -5.0 to -20.0 diopters (D). Follow-up examination...

PURPOSE To assess the safety, efficacy, predictability, and refractive outcome of implanting Ophtec Artisan phakic intraocular lenses (pIOLs) in eyes with keratoconus. METHODS In this retrospective study, 18 eyes of 11 patients diagnosed with keratoconus who underwent toric or myopic pIOL implantation were followed for 1 year postoperatively. Mean patient age was 41+/-10.97 years (range: 23 t...

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. During 6 - 48 months' follow-up, visual acuity, refraction, intraocular pressure (IOP),...

PURPOSE To evaluate the implantation of Artisan/Verisyse phakic intraocular lenses (pIOLs) (Advanced Medical Optics) as an effective and safe method for the correction of high myopia. SETTING Department of Ophthalmology, John A. Moran Eye Center, University of Utah Medical Center, Salt Lake City, Utah, USA. METHODS This retrospective outcomes trial examined the implantation of Artisan/Veris...

Cataract surgery, meaning exchange of the opaque lens in the eye with an artificial lens, is nowadays one of the most successful surgical procedures ever known. It is also the most frequent surgery performed in the Western world. In Sweden alone, more than 100,000 cataract operations are performed annually. Severe complications are rare, occurring only in a few percent of the patients, but owin...

Keratoconus is characterized by progressive corneal protrusion and thinning, leading to irregular astigmatism and impairment in visual function. The etiology and pathogenesis of the condition are not fully understood. However, significant strides have been made in early clinical detection of the disease, as well as towards providing optimal optical and surgical correction for improving the qual...
