The details regarding the validation of this new device are published in the latest issue of Scientific Reports. Multifocal lenses are used in cataract surgeries – to replace the crystalline when it has lost its transparency – or to correct for presbyopia. There are different lens designs in the market, and choosing one or another […]Continue Reading ...

How different cells in a multicellular organism acquire their identities remains a fundamental mystery of development. In the eye, for example, the lens contains two cell types – lens epithelial cells and lens fiber cells — the first of which differentiates into the second as an animal matures. Scientists have long known that fibroblast growth […]Continue Reading ...

As people age, the lens of the eye develops a progressive opacification or clouding called a cataract. Cataracts are a significant cause of visual loss in older adults, and often surgery is performed when the lens causes vision loss to the point where it interferes with daily activities. In most cases, cataract surgery is performed […]Continue Reading ...
University of Alicante researchers have developed a new multifocal contact lens which rests on the white part of the eye (sclera) to correct presbyopia (or tired eyesight) with a more personalised design according to the specific needs of each user. Specifically, the Research Group in Optics & Visual Perception has registered this highly permeable to […]Continue Reading ...
Researchers at the Universitat Politècnica de València, University of Valencia, Instituto de Investigación Sanitaria La Fe and the companies AJL Ophthalmic SA and Aiken-Tecnología Ocular Preventiva SL have designed a new type of intracorneal inlay to correct presbyopia and farsightedness. The design is based on a diffractive lens with micro-holes that permit the flow of […]Continue Reading ...

Cataract surgery is one of the most common and successful surgical procedures performed today. Over the past decade, the risk of severe complications has decreased with advances in surgical instruments and techniques. In the procedure, the cataract (cloudy lens) is removed, and a clear intraocular (in-the-eye) lens is placed. Rare complications include intraocular lens (IOL) […]Continue Reading ...
(HealthDay)—Doctors recently removed a contact lens that was embedded in a woman’s eyelid for nearly three decades after she was hit in the eye while playing badminton. The case was highlighted in the Aug. 10 online edition of BMJ Case Reports. The woman was 14 at the time and thought she had lost the contact […]Continue Reading ...
Sep 19 2018 New four-year study data shows the significant impact of a pioneering contact lens management approach to slowing the progression of myopia (nearsightedness) in children, including those whose treatment begins later. CooperVision is presenting the multi-year study’s latest outcomes during the BCLA Asia conference in Singapore this week, at which the globally increasing […]Continue Reading ...
By Dr Ananya Mandal, MDAugust 16, 2018 A 14 year old girl in United Kingdom around three decades back took a hit in the eye while playing badminton. She then lost her contact lens which was never found. After 28 years, the doctors have found the lens – it was embedded in a cyst in […]Continue Reading ...
May 21, 2018 If you want to take clear photographs, you don’t use sandpaper to clear a smudge from your camera’s lens. Similarly, if you want to see clearly, the lens of your eye has to be free of obstruction. For that reason a curious thing happens during the development of eye lenses. Instead of […]Continue Reading ...
