Another prospective study using the Re STOR IOL after bilateral refractive lens exchange, found that all patients reported satisfaction with their visual outcomes, but rated intermediate vision lowest.A study comparing the Tecnis diffractive IOL to the Re Zoom refractive IOL found higher levels of patient satisfaction and less visual disturbances in the Tecnis group, but less reported problems with intermediate vision in the Re Zoom group, despite no differences in near or distance uncorrected vision between the two groups.This is in contrast with multiple zones of optical power in a multifocal IOL that can result in scattering of light and visual disturbances.EDF lenses, while providing preserved visual quality with fewer halos, can still produce a relatively unique photic phenomenon generally described as starbursts.

You might find it surprising that after undergoing vision correction surgery, you still require eyeglasses for near vision reading.The higher order aberrations and visual quality have been shown in many studies to be similar to that of bifocal diffractive intraocular lenses; however, in bench testing, they are associated with increased halos and reduced distance visual quality when compared to bifocal diffractive IOLs.The Re Zoom IOL is a second-generation refractive IOL, that enhanced some aspects of the Array design, such as enlargement of the second and third zones, reduction of the fourth and fifth zones and an aspheric transition between zones so that visual disturbances could be reduced..Reduced visual quality and visual phenomena such as halos, glare, and starbursts are characteristic of multifocal IOLs due to the light scatter that naturally occurs when transitioning between near and far zones .In a prospective study of 95 eyes comparing multifocal IOLs to monofocal IOLs, 29% of multifocal patients reported glare while 25% reported halos, compared to 19% and 12% in the monofocal group, respectively.
