To further evaluate the clinical performance of the ZM900 Tecnis Multifocal lens on a full complement of multifocal subjects for premarket approval
To further evaluate safety & effectiveness of the lens; specifically, best corrected distance visual acuity will meet or exceed the FDA grid values, complication and adverse event rates will be similar to the FDA grid rates for posterior chamber IOLs, and near visual acuity will be improved compared to that of the monofocal control lens group in the initial evaluation of the ZM900 lens.

Multifocal intraocular lenses (MIOLs) provide enhanced far and near visual acuity, but they can bring about halos and glare, which are caused by design deficiencies of the IOLs. Compared t...
This study evaluated visual outcome after cataract surgery with bilateral implantation of either a diffractive - refractive (hybrid) multifocal intraocular lens (MFIOL) or monofocal intrao...
The purpose of this study is to compare the visual outcomes with bilateral implantation of Tecnis MF and ReSTOR intraocular lenses (IOLs) 6 months post cataract surgery.
The objective of the study is to compare the visual outcomes of three aspheric monofocal intraocular lenses after cataract surgery - ACRYSOF® IQ, Tecnis® and Akreos® MI60.
To compare refractive outcomes and patient's visual quality after bilateral cataract surgery when implanting multifocal intraocular lens, monofocal with monovision or hybrid monovision.
To evaluate visual outcomes with particular attention to intermediate visual acuity (VA), of a segmental refractive multifocal intraocular lens (IOL) with optimized depth of focus (DoF) DESIGN: Prospe...
To analyse the predictability of diverse intraocular lens (IOL) power calculation formulae in paediatric patients with congenital cataract.
To evaluate the effect of intraocular lens (IOL) decentration on optical aberrations with different IOL designs.
In a cataract surgery, the opacified crystalline lens is replaced by an artificial intraocular lens (IOL). To optimize the visual quality after surgery, the intraocular lens to be implanted must be se...
To determine the relationship of the anatomic position of tissue surrounding the ciliary sulcus using ultrasound biomicroscopy (UBM) for measurement of ciliary sulcus parameters and the surrounding ti...
Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.
Presence of an intraocular lens after cataract extraction.
Lenses, generally made of plastic or silicone, that are implanted into the eye in front of the natural EYE LENS, by the IRIS, to improve VISION, OCULAR. These intraocular lenses are used to supplement the natural lens instead of replacing it.
Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)
Absence of crystalline lens totally or partially from field of vision, from any cause except after cataract extraction. Aphakia is mainly congenital or as result of LENS DISLOCATION AND SUBLUXATION.
