Patients don’t have to wait for 2020 to achieve 20/20 vision at near without spectacles or contact lenses. Rather, the advancements we have seen just in the past few years should be enough to help manage their expectations.
A case of cataract surgery with planned presbyopia-correcting IOL implantation– complicated by posterior capsule rupture and a postoperative refractive surprise– reinforced important lessons and provided a new revelation to one experienced surgeon.
Trifocal IOLs can provide good uncorrected vision at near, intermediate, and far. Outcomes in a series of 30 patients show that a toric version of a trifocal IOL (AT Lisa tri 939MP, Carl Zeiss Meditec) delivers those benefits for patients with > 1 D of corneal astigmatism.
We really are at a crossroads in eye healthcare. Wouldn’t a virtual exam be ‘just as good’ as a trip to the eye doctor? To today’s busy consumer, how can we justify leisurely sitting in front of a computer or in a kiosk versus an in-office visit that takes sixty plus minutes and includes that awkward part – dilation?
The U.S. IDE clinical trial of the investigational extended range of vision IOL (Model ZXR00; Tecnis Symfony Extended Range of Vision IOL, Abbott Medical Optics) found that the implant delivered a full range of uncorrected vision and minimized or eliminated the need for spectacle wear in most patients.
