Recent improvements in cataract surgery and intraocular lens (IOL) technology have allowed rapid improvement in quality visual acuity. Cataract surgeons can also reliably reduce a patient's dependency on spectacles. Through careful monitoring of implant power calculations to improve their accuracy and reduce unwanted astigmatism, our patients are now able to enjoy clear, uncorrected vision. Newer technology, such as multifocal IOLs and accommodating IOLs, can provide a return to prepresbyopic visual acuity for the cataract patient.

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
