Through focus image quality of eyes implanted with monofocal and multifocal intraocular lenses
Intraocular lenses (lOLs) are commonly implanted in cataract surgery. Initially lOLs were mainly monofocal, but at present there are many multifocal lOLs available, which are being implanted. Multifocal lOLs have the potential advantage of reducing the dependence on spectacle correction for near vision after cataract surgery. Because the multifocal lOLs superimpose the near and far images on th...
متن کاملMultifocal intraocular "mix and match" lenses.
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...
متن کاملTritan colour contrast sensitivity function in refractive multifocal intraocular lenses.
AIMS To compare tritan colour contrast sensitivity (CCS), without and with glare, in patients with refractive multifocal intraocular lenses (IOLs) and with monofocal intraocular lenses. METHODS Tritan CCS was determined (Moorfields Vision System, CH Electronics) in 15 eyes (14 patients, 75.7 (+/-6.6) years) with a refractive multifocal IOL (Allergan SA 40N) and in 11 eyes (10 patients, 73.7 (...
متن کاملNon-organic Visual Loss in Patients with Multifocal Intraocular Lenses
PURPOSE To report non-organic visual loss (NOVL) following cataract surgery with multifocal intraocular lens (IOL) implantation. METHODS After reviewing consecutive cases of NOVL diagnosed by a single neuro-ophthalmologist over a one year period, two patients reported herein attributed their visual symptoms to cataract surgery and multifocal IOL implantation. RESULTS In both patients variab...
متن کاملComparison of Visual Performance of Multifocal Intraocular Lenses with Same Material Monofocal Intraocular Lenses
PURPOSE To compare the visual performance of multifocal intraocular lenses (IOLs) and monofocal IOLs made of the same material. METHODS The subjects included patients implanted with either Tecnis® monofocal IOLs (ZA9003 or ZCB00) or Tecnis® multifocal IOLs (ZMA00 or ZMB00) bilaterally. We conducted a retrospective study comparing the two types of IOLs. The multifocal group included 46 patient...
متن کاملA Rapid and Convenient Procedure to Evaluate Optical Performance of Intraocular Lenses
A new portable lens scanner was developed and tested for measuring focal lengths and relative contrast transfer of monoand multifocal intraocular lenses (IOLs). A photograph of a natural scene was imaged in white light through an IOL in a water-filled cuvette, with their +21D base power largely neutralized by a −20D trial lens, using a USB monochrome video camera that could be focused via a lap...
