A cataract is a clouding of the eye’s naturally clear lens, causing light rays entering the eye to scatter instead of focusing directly on the retina at the back of the eye. This causes blurred vision.
Cataract development is a normal process of aging, but also may be caused by eye injuries, certain diseases, medications or long-term exposure to sunlight.
Surgery is the only way to remove a cataract, and should be considered once vision impairment begins to negatively impact your quality of life, and your ophthalmologist has performed a thorough eye examination to confirm you are a candidate.
In cataract surgery, one of the safest and most successful surgical procedures performed today, the cloudy lens is removed through a tiny surgical incision roughly the size of a pen tip. The natural lens is replaced with a permanent intraocular lens (IOL) implant.
The success rate of cataract surgery is excellent – as improved vision at a range of distances is achieved for patients, providing other vision problems are not present. Patients return home the very same day, and the results are truly life-changing.
Purpose: To evaluate whether postoperative refractive power adjustment of a light-adjustable lens (LAL; Calhoun Vision, Inc, Pasadena, CA) improves refractive outcomes in patients who have undergone prior LASIK or photorefractive...
Petite mais puissante : la start-up Swiss Advanced Vision a inventé une lentille intraoculaire révolutionnaire pour l'opération de la cataracte. Inventée par le physicien Robert Apter, elle permettrait de restituer une vision parfaite aussi bien de loin que près, contrairement à la plupart des lentilles intraoculaires pour la cataracte, procurant une vue optimale seulement pour la vision de loin.
With hundreds of millions of people choosing contacts for either visual or aesthetic reasons, and millions more having surgery to solve vision problems associated with aging, there is a growing need for high-volume manufacturing process control for ophthalmic products. Proper process control will improve yield and comfort for the wearers as well as ensure quality manufacturing. This application note discusses the manufacture and production of various contact lenses and intraocular implantable lenses (IOLs) and how properly deployed metrology, using advanced 3D optical microscopes provide a high return on investment to manufacturers in this space.
Multifocal Lenses: In cataract surgery, an intraocular lens (IOL) is the replacement lens that is surgically implanted in the eye to replace the existing cloudy lens. Traditionally, the replacement lens used for cataract surgery is a monofocal IOL. This type of lens restores good functional distance vision, but patients may still need to continue wearing reading glasses.
