Visual outcome and optical quality after bilateral implantation of aspheric diffractive multifocal, aspheric monofocal and spherical monofocal intraocular lenses: a prospective comparison.
AIM To evaluate the visual function after bilateral implantation of aspheric diffractive multifocal Tecnis ZMA00, aspheric monofocal ZA9003 versus spherical monofocal Akreos Adapt intraocular lenses (IOLs). METHODS Tecnis ZMA00, Tecnis ZA9003 or Akreos Adapt IOLs were bilaterally implanted in 180 eyes from 90 patients. The following parameters were assessed 3 months postoperatively: monocular...
متن کاملDesign of isoplanatic aspheric monofocal intraocular lenses.
A new and complete methodology of monofocal intraocular lens (IOL) design is presented aiming at isoplanatism, i.e. IOLs that provide the eye with optimized optical quality over a wide field of view (typically in a range of ten degrees). The methodology uses a merit function considering dimensional and biomechanical constraints, and a geometrical optical quality metric that is evaluated simulta...
متن کاملOptical performance of monofocal versus multifocal intraocular lenses.
In their recent paper, Ortiz et al. studied the optical performance of monofocal and multifocal intraocular lenses (IOLs) in the human eye. Their main conclusion was that of the IOLs studied, the hybrid refractive–diffractive IOLwas the least affected by pupil diameter in terms of intraocular aberrations. This IOL type also showed a smaller increase in optical aberrations during pupil dilation....
متن کاملEvaluation of rotation and visual outcomes after implantation of monofocal and multifocal toric intraocular lenses.
PURPOSE To evaluate rotational stability and its influence on postoperative visual acuity of different monofocal and multifocal toric intraocular lenses (IOLs). METHODS A prospective interventional study was designed. Ninety-one patients with a mean age of 71.65 ± 11.82 years were implanted with toric IOLs after phacoemulsification. Three monofocal toric IOLs (the Lentis LT [Oculentis, Berlin...
متن کاملCompared optical performances of multifocal and monofocal intraocular lenses (contrast sensitivity and dynamic visual acuity)
The functional results (contrast sensitivity and dynamic visual acuity) of 19 multifocal (3M design) and 14 all polymethylmethacrylate biconvex monofocal intraocular lenses (IOLs), 6 mm in optical diameter were compared. Best corrected visual acuity was > or = 8/10 (Monoyer chart) Parinaud 2 in all cases. Major differences of functional performance in favour of monofocal IOLs were found outside...
