For those considering cataract surgery, this is a must read. Below is an excerpt from the introduction.The entire article, "Multifocal intraocular lenses: Relative indications and contraindications for implantation" is here: http://www.ascrs.org/sites/def...tifocal%20IOLs_0.pdf (J CATARACT REFRACT SURG -VOL 40, FEBRUARY 2014)
“Achieving spectacle independence is challenging; it may be very challenging when choosing lifestyle IOLs, particularly multifocal IOLs, for certain patients. Not every currently available IOL is suitable for every patient due to the complexity of lifestyle choices and personality dynamics or the inherent anatomy and physiology of the eye. This paper reviews the best clinical practice to approach patients considering multi- focal IOLs in conjunction with cataract surgery by reviewing recommended diagnostic testing, patient evaluations, and management choices, especially when dealing with certain anatomical or physiological ocular challenges.
The review does not address multifocal IOL choices in patients having refractive lens exchange. The cataract population will tend to be much more forgiving of the associated optical tradeoffs of diffractive multi-focal IOLs compared with a purely refractive population with generally excellent visual quality but spectacle dependence. Refractive patients are more prone to notice the side effects of multifocal IOL correction.”
