The aims of this study are to:
- Demonstrate a reduction in postoperative cylinder compared to results from the control lens
- Exceed monocular best corrected distance visual acuity results provided in ISO guidelines.

This study is to compare the clinical outcome of Precizon toric intraocular lens(IOL) to that of Tecnis toric IOL.
Post-approval study to evaluate the rates of visual distortions for patients requiring >2.0 D of corneal astigmatism correction
Evaluate efficacy and safety of the toric IOL implanted into aphakic eye with corneal astigmatism after cataract surgery.
Glaucoma is a leading cause of blindness worldwide. Damage to the optic nerve results in vision loss gradually. This vision loss can be detected by using visual field testing, and is a way...
The purpose of this study is to determine if Toric intraocular lens implantation in cataract surgery is a more efficient and cost-effective treatment of astigmatism than Monofocal intraocu...
To evaluate the cost-effectiveness of toric versus monofocal intraocular lens (IOL) implantation in cataract patients with bilateral corneal astigmatism.
To determine whether any of three keratometry devices is superior to the others in predicting the ideal toric intraocular lens (IOL) alignment meridian.
To evaluate refractive outcomes of cataract surgery in previously vitrectomized eyes and compare the accuracy of intraocular lens (IOL) calculation formulas in this population.
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...
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.
