B&L Aspheric Lenses- the next step in IOL evolution
نویسنده
چکیده
with a negative spherical aberration designed to compensate for positive spherical aberration found in the cornea of the typical cataract patient. However, these lenses depend on precise positioning. A small offset in centration may result in significant higher order aberrations such as coma, along with significant visual impairment. These negative spherical aberration IOLs are contra-indicated in situations where you may expect less than perfect IOL centration.

Comparison of higher order aberrations with spherical and aspheric IOLs compared to normal phakic eyes.
PURPOSE To compare higher order aberrations (HOA) in AcrySof SN60AT and Acrysof IQ SN60WF intraocular lenses (IOLs) and natural crystalline lenses in an age-matched population. METHODS Sixty-nine eyes of 55 patients were examined. Group I included AcrySof spheric lenses, group II AcrySof aspheric lenses, and group III included patients with the natural crystalline lens. The HOA data were obta...

In the current era of presbyopia-correcting intraocular lenses (IOLs), toric IOLs and aspheric IOL technology, the practice milieu is changing. Informed consent takes on newmeaning when the surgeon and the patient decide together which IOL technology represents the best fit for a particular life style and its visual demands. Customizing IOL choice is no longer optional; it is essential to the p...
متن کاملComparison of retinal image quality with spherical and customized aspheric intraocular lenses
We hypothesize that an intraocular lens (IOL) with higher-order aspheric surfaces customized for an individual eye provides improved retinal image quality, despite the misalignments that accompany cataract surgery. To test this hypothesis, ray-tracing eye models were used to investigate 10 designs of mono-focal single lens IOLs with rotationally symmetric spherical, aspheric, and customized sur...

PURPOSE To determine the energy distribution between the distance and near images formed in a model eye by spherical and aspheric apodized diffractive multifocal intraocular lenses (IOLs). METHODS The IOL was inserted in a model eye with an artificial cornea with positive spherical aberration (SA) similar to that of the human cornea. The energy of the distance and near images, as a function o...
