Accommodative intraocular lenses for age-related cataracts.
The standard intraocular lens (IOL) that is used to replace a cataractous lens cannot change focus from distant to near objects, so most patients need glasses for near vision after cataract surgery. Limited evidence suggests that accommodative IOLs provide better near vision than monofocal IOLs, but not better than multifocal IOLs. Long-term follow-up is needed to confirm patient outcomes, and ...
متن کاملAberrometry in patients implanted with accommodative intraocular lenses.
PURPOSE To evaluate the objective accommodative response, change of aberrations, and depth of focus in eyes implanted with the Crystalens accommodative intraocular lens (IOL) at different accommodative demands. DESIGN Prospective, observational study. METHODS Eleven cataract patients (22 eyes) who underwent implantation of a Crystalens accommodative IOL, and control groups of 9 normal subje...
متن کاملAccommodative intraocular lenses: where are we and where we are going
Presbyopia still remains the last frontier of refractive surgery. Its surgical management is under constant evolution due to the limitations that exist today with respect to its management, which is probably in relation with the multifactorial basis in which presbyopia is clinically developed in the human. Until currently, virtually all surgical techniques that have been proposed for its correc...
متن کاملA stepwise approach for the management of capsular contraction syndrome in hinge-based accommodative intraocular lenses
PURPOSE The aims of this study are to define the various stages of capsular contraction syndrome (CCS) and its effect on refractive error with hinge-based accommodating intraocular lenses (IOLs) and to describe a systematic approach for the management of the different stages of CCS. METHODS Hinge-based accommodative IOLs function via flexible hinges that vault the optic forward during accommo...
متن کاملAnalysis of Accommodative Performance of a New Accommodative Intraocular Lens.
PURPOSE To compare objective and subjective accommodation and visual acuities with a new accommodative intraocular lens (IOL) (Lumina; AkkoLens Clinical BV, Rijswijk, The Netherlands) with a monofocal IOL and young phakic eyes. METHODS In this prospective, randomized controlled clinical investigation, patients aged 51 to 85 years with symptomatic cataract were enrolled in the study. A total o...
