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.

Custom-designed contacts improve vision for subjects with keratoconic eyes

Keratoconic eyes are rare but disabling. From the side, the eyes look more pointed or cone-shaped than round. The apex shift from visual axis in the cornea causes people with the condition to see halos and double and triple images. About 1 in 2,000 people suffer from the disease, usually in both eyes.

Younger children capable of handling contact lenses

Children 8 to 12 years old are just as adept as teenagers at handling and wearing contact lenses.

FDA warns about risks of using decorative contact lenses

This Halloween season, the U.S. Food and Drug Administration (FDA) is again warning consumers about the serious risks of using decorative contact lenses without the appropriate involvement of an eye care professional.

Simple sight test and glasses could make a dramatic difference to the lives of more than 150 million people

Children fail at school, adults are unable to work and families are pushed into poverty as a result of uncorrected visual impairment.

Going deaf and blind happens simultaneously in old age

According to Australian scientists, vision and hearing loss happens almost simultaneously in older people.

Ophthalmologists improve LASIK

Ophthalmologists have developed a formula that slashes by nearly two-thirds the likelihood that patients will need repeat visits to an eye surgeon to adjust their vision after their initial LASIK visit. That's because the formula makes it more likely that surgeons will get it right the first time.

FDA statement on Bausch & Lomb inspection

Yesterday, the Food and Drug Administration (FDA) issued Bausch & Lomb a report detailing its observations at the conclusion of the inspection of the Greenville, SC plant and a related facility as part of an investigation into a recent increase in Fusarium keratitis infections associated with contact lens wearers using the ReNu with MoistureLoc contact lens cleaning solution.

14 million Americans are visually impaired

A National Eye Institute (NEI) study has found that although 94 percent of Americans aged 12 and older have good vision, the remaining six percent, or 14 million, are visually impaired.

Patching for corneal abrasion

Simple corneal abrasions do not need to be treated by patching the eye, according to a new review of studies that found patching initially slows healing and does not reduce pain.

$Photorefractive keratectomy (PRK) versus laser-assisted in-situ keratomileusis (LASIK) for myopia$

Photorefractive keratectomy (PRK) versus laser-assisted in-situ keratomileusis (LASIK) for myopia

A new review of recent studies suggests two popular laser-assisted surgeries to correct nearsightedness are equally effective at restoring 20/20 vision six months to a year after the surgery.

New implanted lens to fix nearsightedness

UT Southwestern Medical Center ophthalmologists will be the first in the area to insert a new type of implanted lens to fix nearsightedness.

Antibacterial coatings on hip and knee implants cut infection rates

Putting antibacterial coatings on hip and knee implants and biomedical devices such as catheters could cut infection rates following surgery and significantly reduce health care costs and improve quality of life for patients, researchers at the University of South Australia have found.

Study of 30-day extended wear contact lenses

A team of researchers led by the Johns Hopkins Wilmer Eye Institute have determined that the corneal infection rate associated with the use of 30-day -extended-wear contact lenses made from silicone hydrogel is comparable to that previously reported for older lens types worn for fewer consecutive 24-hour periods.

Researchers characterize the proteome of the human cornea

In doing so, they have identified 141 distinct proteins, 99 of which had not been previously recognized in mammalian corneas. The details of their findings appear in the August/September issue of Molecular and Cellular Proteomics, an American Society for Biochemistry and Molecular Biology journal.

New generation of lenses makes evolutionary leap in eliminating need for glasses

The need for reading glasses or bifocals as we age may begin fading from sight with the latest generation of intraocular lenses.

New laser-surgery technique to perform cornea-transplant surgery

A UC Irvine ophthalmologist and his team have invented a new laser-surgery technique to perform cornea-transplant surgery that can replace the use of traditional handheld surgical blades and potentially improve recovery time for patients.

$Laser refractive surgery is a safe, effective way to correct myopia, hyperopia and astigmatism$

Laser refractive surgery is a safe, effective way to correct myopia, hyperopia and astigmatism

Hopkins researchers have found that patients experiencing vision problems following cataract removal and intraocular lens implantation (CE-IOL) may have better results from laser refractive surgery, which spares them potential complications of lens implant replacement and the inconvenience of glasses.

Sleeping in contact lenses can lead to an increased risk of severe eye infection

The University of Manchester study found that wearers who failed to remove their lenses before bedtime had an increased risk of developing keratitis than those who routinely took out their lenses before going to sleep.

New contact lenses cause less infections

Sleeping with your contact lenses in can give you a nasty eye infection (keratitis), but now a new generation of silicone hydrogel lenses cuts that risk fivefold, according to research in the British Journal of Ophthalmology.
