FEBRUARY 2012 CAtARACt & REFRACtivE SURgERY todAY 39 A lthough much has been written on the topic, there is no universally accepted treatment for presbyopia. Therapies range from bifocal spectacles to scleral expansion to accommodating IOLs to corneal procedures such as presbyLASIK or conductive keratoplasty. An intrastromal approach is currently being investigated in FDA clinical studies for t...

We describe and demonstrate a pair of diopter-adjustable eyeglasses aimed to correct presbyopia; the glasses provide a tunable optical power in the whole surface of the lens cell, eliminating the optical distortion typical of bifocal/trifocal or progressive glasses. The wearer can actively control the optical power by a simple sliding gesture on the bridge of the glasses, so that presbyopic vis...

PURPOSE The NeuroVision technology is a noninvasive, patient-specific, perceptual learning program based on visual stimulation and facilitation of neural connections at the cortical level, involving a computerized visual training regimen using Gabor patches, to improve contrast sensitivity and visual acuity. The efficacy of NeuroVision in enhancing uncorrected visual acuity (UCVA) and unaided c...

PURPOSE To investigate non-cycloplegic changes in refractive error prior to the onset of presbyopia. METHODS The Aston Longitudinal Assessment of Presbyopia (ALAP) study is a prospective 2.5 year longitudinal study, measuring objective refractive error using a binocular open-field WAM-5500 autorefractor at 6-month intervals in participants aged between 33 and 45 years. RESULTS From the 58 p...

The new generation multifocal lenses provide the surgeon with several options to meet the specific visual needs and desires of patients. A revolution in presbyopia surgery is being driven by two multifocal intraocular lenses, ReStor and ReZoom. Combined implantation of the ReZoom multifocal lens in nondominant eye and ReStor multifocal lens in dominant eye has been demonstrated to produce stati...
