Contact Lenses News and Research

RSS

Contact lenses are explicitly designed optical devices that can be worn directly on the cornea of the eye. People with poor eyesight wear contact lenses, which helps to refocus oncoming light rays on the retina to achieve a clear vision. Contact lenses increase or decrease the focusing potential of the cornea, and thereby directly project light onto the retina and aid in treating refractive errors.

Cataract surgery followed by use of contact lenses may be better solution for infants

For adults and children who undergo cataract surgery, implantation of an artificial lens is the standard of care. But a clinical trial suggests that for most infants, surgery followed by the use of contact lenses for several years—and an eventual lens implant—may be the better solution.

Scientists create 3-D elastic membrane that is precisely shaped to match heart's epicardium

Igor Efimov, PhD, at the School of Engineering & Applied Science at Washington University in St. Louis and an international team of biomedical engineers and materials scientists have created a 3-D elastic membrane made of a soft, flexible, silicon material that is precisely shaped to match the heart's epicardium, or the outer layer of the wall of the heart.

Researchers discover easy-to-use method for bonding gels and biological tissues

Researchers have discovered an efficient and easy-to-use method for bonding together gels and biological tissues. A team headed by Ludwik Leibler, involving researchers from the Laboratoire Matière Molle et Chimie (CNRS/ESPCI ParisTech) and the Laboratoire Physico-Chimie des Polymères et Milieux Dispersés (CNRS/ UPMC/ESPCI ParisTech), has succeeded in obtaining very strong adhesion between two gels by spreading on their surface a solution containing nanoparticles.

Researchers one step closer to development of drug-eluting contact lens for glaucoma treatment

For nearly half a century, contact lenses have been proposed as a means of ocular drug delivery that may someday replace eye drops, but achieving controlled drug release has been a significant challenge. Researchers at Massachusetts Eye and Ear/Harvard Medical School Department of Ophthalmology, Boston Children's Hospital, and the Massachusetts Institute of Technology are one step closer to an eye drop-free reality with the development of a drug-eluting contact lens designed for prolonged delivery of latanoprost, a common drug used for the treatment of glaucoma, the leading cause of irreversible blindness worldwide.
