The global Intraocular Lenses (IOLs) market is projected to reach US.8 billion by 2024, driven by the rising prevalence of cataract among the rapidly aging world population and strong adoption of premium IOLs.
During your preoperative exam and consultation, your cataract surgeon can help you choose the best IOL for your needs, as well as additional cataract surgery costs involved if you choose one of the following premium lens implants.
Traditional intraocular lenses have a spherical optical design, meaning the front surface is uniformly curved from the center of the lens to its periphery.
They also have alignment markings on the peripheral part of the lens that enable the surgeon to adjust the orientation of the IOL inside the eye for optimal astigmatism correction.
Just prior to cataract surgery, the surgeon places temporary markings on the patient's cornea that identify the location of the most curved meridian of the front of the eye.
Premium aspheric IOLs, on the other hand, match more closely the shape and optical quality of the eye's natural lens, and thereby can provide sharper vision especially in low light conditions and for people with large pupils.
Popular aspheric IOLs that are FDA-approved and available in the U. include: Tecnis Aspheric (Abbott Medical Optics), Acry Sof IQ (Alcon), Sof Port AO (Bausch Lomb), and Softec HD (Lenstec).The following is an overview of premium IOLs currently that are FDA-approved for use by cataract surgeons in the United States.These are considered "premium" intraocular lenses because they have advanced features beyond those found in basic single vision IOLs that are covered by Medicare and other types of health insurance.And, with Presbyopia the eye's natural lens becomes less flexible and is unable to focus light as it once did; presbyopia makes it difficult to focus on objects or words that are close to you.But cataracts, astigmatism and presbyopia don’t mean a permanent loss of vision or giving up activities.FDA-approved IOLs have been available since the early 1980s.
