Small-aperture IOL offers advantages over other presbyopia lenses
Small-aperture IOL offers advantages over other presbyopia lensesA new small-aperture intraocular lens (IOL) extends patients’ depth of focus as well as multifocal IOLs with fewer dysphotopsias, researchers say.
FDA approves one-of-a-kind IOL with extended range of vision
FDA approves one-of-a-kind IOL with extended range of visionIt has been a history-making week for the ophthalmic world, and the FDA approval of the first IOL with extended range of vision (Tecnis Symfony IOL, Abbott) has only added one more reason for celebration.
How IOL platform designs are achieving quality of visionPatient satisfaction is high following implant of the Symfony IOL, which is designed with an elongated focal zone in an attempt to minimise visual compromises and avoid visual dysphotopsias.
U.S. surgeons anticipate new IOLsWith a wide array of IOL options available to their foreign colleagues, U.S. ophthalmologists eagerly await the approval and availability of additional lenses.
Identifying, managing dysphotopsia after cataract surgeryFollowing cataract surgery, patients can present with a variety of visual complaints—i.e., dysphotopsias, aberrant optical phenomena that interfere with vision after IOL implantation. Positive dysphotopsias include rainbows, streaks, crescents, rings, halos, and veiling glare, haze, and fog. Negative dysphotopsias are relative and absolute scotomas, said Jack T. Holladay, MD, from Baylor College of Medicine, Houston.
