Eye Implant Regulates Intraocular Pressure

Eye Implant Regulates Intraocular Pressure

Eye Implant Regulates Intraocular Pressure Elevated or diminished eye pressure impairs our ability to see, and in the worst cases, can even lead to blindness. Until now, there has been no effective long-term treatment. In response, Fraunhofer researchers are developing an implantable microfluid system that can efficiently and durably stabilize intraocular pressure. Glaucoma and phthisis bulbi are incurable, insidious diseases ... Read More »

Cataract Culprits ( Genes linked to cataract formation )

Cataract Culprits ( Genes linked to cataract formation )

Cataract Culprits ( Genes linked to cataract formation ) When cataracts encroach on the eyes, the only effective remedy is to surgically replace the eyes’ lenses with synthetic substitutes. But what if scientists found a way to delay or prevent cataracts from forming in the first place? Cataract culprits A study of regulatory genes by the Lachke Lab at the ... Read More »

Colorblindness Glasses

Colorblindness Glasses

Colorblindness Glasses A person with red-green color blindness (more accurately called color vision deficiency) experiences the world differently because their red and green photopigments have more overlap than normal. By overlap, we mean spectral overlap, which is related to how the photopigments absorb light. Lets take a moment to understand how that happens: The photopigments are the light-absorbing molecules found in the ... Read More »

Dry Eye Device

Dry Eye Device

Dry Eye Device Dry eye syndrome (DES) also called Keratoconjunctivitis sicca (KCS) or keratitis sicca, is an eye disease caused by eye dryness, which, in turn, is caused by either decreased tear production or increased tear film evaporation. It is found in humans and some animals. KCS is the most common eye disease, affecting 5 – 6% of the population. Prevalence rises to 6 ... Read More »

KAMRA Inlay Corneal Implant to Replace Reading Glasses Reading glasses are a necessity for most people older than 40, when the blurriness known as presbyopia overtakes their ability to focus. Soon enough, it seems, middle-aged Americans will catch up with the rest of the world. A corneal inlay product, which is already sold in other parts of the world, is ... Read More »

Multifocal IOL evolution

Multifocal IOL evolution

Multifocal IOL evolution By Cheryl Guttman Krader; Reviewed by Rudy M.M.A. Nuijts, MD, PhD, and Soraya M.R. Jonker, MD Maastricht, The Netherlands—If the ultimate goal of implanting a multifocal IOL (MFIOL) is to achieve spectacle independence after cataract surgery, then choosing a lens with a trifocal diffractive optic may be more advantageous than one with a bifocal diffractive design. Such is ... Read More »

Muller’s muscle conjunctival resection (MMCR) For Ptosis

Muller’s muscle conjunctival resection (MMCR) For Ptosis

Muller’s muscle conjunctival resection (MMCR) For Ptosis Müller’s muscle (MM) is a sympathetically innervated upper eyelid muscle that, together with the levator palpebral superioris, elevates the eyelid. The MM resembles smooth muscle, and originates from the levator aponeurosis about 15 mm above the superior tarsus. The MM is adherent to the conjunctiva but easily separable from the levator aponeurosis, and ... Read More »
