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...

Anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. It is also called X-linked megalocornea. It is accompanied by early development of cataracts, zonular anomalies, and, rarely, vitreoretinal disorders. Subluxation of a cataract can occur in cataract surgery because of zonular weakness. In addition, in most patient...

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...

The early development of lens opacities and lens subluxation are the most common causes of vision loss in patients with anterior megalophthalmos (AM). Cataract surgery in such patients is challenging, however, because of anatomical abnormalities. Intraocular lens dislocation is the most common postoperative complication. Patients with AM also seem to be affected by a type of vitreoretinopathy 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),...
