A study conducted by a team lead by Dr. John Bullock of Wright State University’s Boonshoft School of Medicine found that improper temperature control of Bausch & Lomb’s ReNu with MoistureLoc may have contributed to the outbreak of a fungal infection of the cornea in 2008. The study was published in the peer-reviewed Archives of Ophthalmology.

A study showed that posterior chamber phakic IOL implantation treated myopia and astigmatism in patients who underwent previous penetrating keratoplasty (PK). The prospective study included 15 eyes of 15 patients with a mean age of 37.8 years who underwent previous PK and were unable to wear spectacles or contact lenses or to undergo corneal refractive surgery.

A gene associated with the formation of age-related cataract, a leading cause of blindness, has been identified by scientists. According to the study published in the July 31 issue of the journal PLoS Genetics, the EphA2 gene encodes an enzyme that plays a role in the repair of damaged proteins in the eye. However, the expression of the EphA2 gene decreases with age. As a result, damaged proteins can clump together and cause the eye lens to become cloudy, leading to obscured vision.

According to Adam Gordon, an associate professor in the School of Optometry, bifocal glasses can prove handy, but for those who wear contacts, presbyopia has been an annoying part of aging. This problem can be resolved through the new multifocal lenses, which are made with silicone hydrogel polymer, a more breathable and safer material than older soft-lens polymers, Gordon said. Cutting-edge laser technology used in these lenses improves focus on nearby objects.
