Research summary
The desire to be free from glasses is a common request in ophthalmology clinics, and is becoming increasingly popular. Multifocal intraocular lenses (IOLs) are commonly used in attempt to provide patients with a range of clear vision and therefore spectacle independence. Multifocal IOLs are implanted after the eye's natural lens is removed, during either cataract surgery or refractive lens exchange (when no cataract is present). The ideal multifocal IOL should provide a range of clear vision from distance viewing (e.g driving) to near viewing (e.g. reading a novel), does
not negatively impact contrast sensitivity, and does not produce significant levels of dysphotopsias (e.g. glare from light, or haloes around lights). There are various different designs of multifocal IOLs available that set out to achieve
this. Multifocal IOLs achieve a range of clear vision by splitting light, and it is well recognised that this can cause various light related visual side effects. Therefore, enhanced monofocal IOLs, which are lenses that do not split light have been introduced, and in theory produced less unwanted light related side effects. These lenses provide their depth of focus through spherical aberration and leaving the nondominant eye slightly shortsighted. This study aims to assess the outcomes following bilateral implantation of enhanced monofocal IOLs. The objective visual and refractive outcomes and subjective patient reported outcomes following cataract extraction surgery or refractive lens exchange with implantation of enhanced monofocal IOLs will be assessed and outlined. This will help provide information on the level of vision achieved, the level of quality of vision and overall satisfaction achieved with this new IOL design.REC name
