Strengthening miniaturized titanium-based medical devices: an interview with Dr Masaru Rao, University of California, Riverside

While titanium is used widely for more conventional macro-scale medical devices (e.g. hip implants, dental implants, and cardiac pacemakers), its use for micro- and nano-scale devices has been limited thus far.

Massachusetts hospital performs first cornea transplant with pre-loaded donor tissue

The first successful cornea transplant with donor endothelial tissue preloaded by an eye bank has been performed at Massachusetts Eye and Ear in Boston, Mass. Roberto Pineda II, M.D., Director of the Refractive Surgery Service at Mass. Eye and Ear, and an Associate Professor of Ophthalmology at Harvard Medical School, recently performed the groundbreaking transplant.

Study: Gene mutations are associated with severe form of nearsightedness

People have long taken for granted that glasses and contact lenses improve vision for nearsightedness, but the genetic factors behind the common condition have remained blurry. Now researchers at Duke Medicine are closer to clearing this up.

Research findings provide new hope for people suffering from dry eye disease

Natural lubricants play an important role in health, including a well-known effect to help prevent osteoarthritis in knee and ankle joints. However, much is still unknown about their role and function in other areas of the body.

Implant improves vision for patients suffering from macular degeneration

Physicians at the Virginia Commonwealth University Medical Center have become the first in Virginia to successfully implant a telescope in a patient's eye to treat macular degeneration.

Genes for blood vessel growth in retina are "switched on" by SRF protein

Normal functioning of the eye depends on a proper supply of blood to the retina. Light entering the eye passes through the cornea, the lens, and the vitreous body before reaching the retina, where it stimulates the nerves.

DSEK surgical procedure for perfect vision

Since she was a child Sarah Mittler knew exactly what she wanted to do−be a wife and mother. She and her husband, Tom, were living their dream of a life complete with five kids, two dogs and a packed schedule of activities, until Sarah's vision started to deteriorate.

FDA clears LENSAR Laser System to perform corneal, arcuate incisions during cataract surgery

LENSAR Inc., developer of the next generation LENSAR Laser System™ for refractive cataract surgery, announced today that the company's laser system has received 510(k) clearance from the United States Food and Drug Administration for the execution of arcuate incisions during cataract surgery.

Wearing OK contact lenses every night can restore age-related loss of near vision

By middle age, most people have age-related declines in near vision (presbyopia) requiring bifocals or reading glasses. An emerging technique called hyperopic orthokeratology (OK) may provide a new alternative for restoring near vision without the need for glasses, according to a study, "Refractive Changes from Hyperopic Orthokeratology Monovision in Presbyopes", appearing in the April issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Study confirms rapid effectiveness of temporary, nonsurgical alternative to LASIK

A contact lens technique called overnight orthokeratology (OK) brings rapid improvement in vision for nearsighted patients. Now a new study shows that OK treatment works mainly by flattening the front of the cornea, reports a recent study, "Posterior Corneal Shape Changes in Myopic Overnight Orthokeratology", appearing in the March issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Eye-rubbing may provoke, aggravate keratoconus

Rubbing the eyes leads to an increase in protease activity and levels of protease and inflammatory mediators, a clinical study shows.

Study finds new mutation in UBIAD1 gene that causes Schnyder corneal dystrophy

Research conducted by Dr. Jayne S. Weiss, Professor and Chair of Ophthalmology at LSU Health Sciences Center New Orleans, and colleagues has discovered a new mutation in a gene that causes Schnyder corneal dystrophy (SCD.)

Dompé initiates enrollment in rhNGF phase I/II REPARO study for neurotrophic keratitis

The first patient has been enrolled in the phase I/II REPARO study, the first international clinical trial evaluating the ophthalmological use of a topical solution of recombinant human Nerve Growth Factor (rhNGF) for the treatment of moderate to severe neurotrophic keratitis (NK).

Study identifies genes for central corneal thickness that may cause eye conditions

Scientists at Singapore Eye Research Institute and A*STAR's Genome Institute of Singapore have succeeded in identifying genes for central corneal thickness that may cause potentially blinding eye conditions. These eye conditions include glaucoma, as well as the progressive thinning of the cornea, which may eventually lead to a need for corneal transplantation.

Scientists develop two novel model systems for human corneal endothelium

Human corneal endothelial cells (HCEnCs) form a monolayer of hexagonal cells whose main function is to maintain corneal clarity by regulating corneal hydration. Cell loss due to aging or corneal endothelial disorders, such as Fuchs dystrophy, can lead to cornea edema and blindness, resulting in the need for cornea transplants.

Children's eyes at greater risk for permanent damage from sunlight

Anderson Cooper, host of "Anderson Live," was temporarily blinded for 36 hours following a two-hour boat trip in Portugal where the sun damaged and burnt his cornea. Eye health concerns like cataracts, skin cancer of the eyelids and melanoma in the retina can all result from sun-damaged eyes.

Watch out for Sjögren's syndrome in dry eye

Clinicians with patients who have clinically significant dry eye should be on the alert for underlying Sjögren's syndrome, report researchers in the British Journal of Ophthalmology.
