Early results of trifocal IOL exhibit solid performanceResearchers conducted a 6-month study of patients implanted with the AcrySof IQ PanOptix presbyopia-correcting IOL to determine the binocular defocus curve of the lens. They concluded that these early results show good visual performance across the whole range of defocus. No unexpected adverse events were reported
Sulcus refractive IOLs solid option for presbyopia, other refractive errorsImplantation of a sulcus-supported, pseudophakic supplementary intraocular lens (IOL) can be a safe and effective method for improving vision in eyes with residual refractive error after cataract extraction, refractive lens exchange, or keratoplasty, said Thomas Kohnen, MD, PhD. It also can be used to provide reversible presbyopia correction.
Phakic IOLs: Good benefit-to-risk ratioThe benefit-to-risk ratio of phakic IOLs is well-balanced, and while there is a risk of decreased endothelial cell counts in some eyes with certain phakic IOLs, the optical quality achieved is very good, said Thomas Kohnen, MD, PhD.
Examining anterior chamber phakic IOL for high myopiaThe hydrophobic, acrylic, anterior chamber phakic IOL (AcrySof Cachet, Alcon Laboratories) performed well in a 5-year study of its safety and efficacy, according to Thomas Kohnen, MD, PhD. Most importantly, he said, the decrease in the corneal endothelial cell count was low and there were low rates of serious adverse events.
