As a new multifocal IOL concept, refractive rotational asymmetry has been introduced into clinical practice for about a half decade, the main part of the lens behaves as a standard monofocal IOL, but in a specific sector of the lens, light is split into numerous foci.
Modern cataract surgery with intraocular lens (IOL) implantation results in improved vision and visual function in more than 90% of the cases.1 Currently, monofocal IOL implantation is the standard of care worldwide.
Data from Abbott's study showed that people with cataracts who received the Tecnis Symfony lens achieved significantly improved intermediate, as well as near, vision compared to those who were given a monofocal IOL.
Denser cataracts where OCT macula& RAM is not possible makes difficult in decision making and the decision more towards monofocal IOL is encouraged.
(26) Such an outcome may affect the lens selection as the IOL will need to be housed in the ciliary sulcus, whereupon a monofocal IOL is most commonly used.
New data demonstrate cataract patients implanted with an AcrySof monofocal IOL are less likely to develop posterior capsule opacification (PCO) or to require a Nd:YAG laser procedure to correct PCO after cataract surgery than those implanted with a non-AcrySof monofocal hydrophilic or hydrophobic IOL.
have compared the outcomes of Tecnis Symfony IOL with those of Tecnis monofocal IOL and concluded that the ERV IOLs provided better distance, intermediate, and near visual acuity than the aspheric monofocal IOL, while maintaining the same level of visual quality [15].
As the name implies, the lens is an add-on IOL, therefore explantation of the primary/original monofocal IOL (implanted during cataract surgery) from the capsular bag is not required.
The approval is based on a review of results from a randomized clinical trial comparing 148 cataract patients implanted with the Tecnis Symfony IOL to 151 cataract patients implanted with a monofocal IOL. The study evaluated visual acuity at near, intermediate and far ranges; contrast sensitivity (the ability to distinguish small differences between light and dark); and adverse events for six months after implantation.
* In the first group 25 eyes of 25 patients underwent phacoemulsification with monofocal iol implantation and in the 2nd group 25 eyes of 25 patients underwent phacoemulsification with multifocal implantation.
A previous study [14] from our research group reported the visual and refractive outcomes of a combined procedure (ICRS + monofocal IOL implantation).
Removing the crystalline lens and replacing with a spherical monofocal IOL leaves positive aberration of the cornea inducing high-order aberrations.
