Soft and Rigid Contact Lenses for Infantile Nystagmus StudiedInfantile nystagmus is not a very common issue, but when it does occur, it may have serious effects on a child’s vision. Consequently, researchers keep looking for new ways of treating it. Recently, a team of investigators have conducted a study assessing the effectiveness of soft and rigid gas permeable contact lenses in managing the condition.

The study was randomised, controlled and had an intention-to-treat design. It included 24 patients with infantile nystagmus, who were randomly assigned to two groups. The groups differed in the sequence of treatment they received. The researchers measured the intensity of nystagmus at 1.2 and 0.4 m. In addition, they evaluated the patients’ best corrected visual acuity and gaze-dependent visual acuity.

Having collected and analysed the data, the authors of the study found no statistically significant differences in any of the evaluated characteristics of nystagmus between soft and rigid contact lenses as well as spectacles. The best-corrected visual acuity turned out to be worse in the case of soft contact lenses, but the difference was small.

The authors of the study concluded that contact lenses are as effective as glasses in treating nystagmus and that rigid gas permeable contacts provide slightly better vision than soft ones in patients with this condition.

US Contact Lens Market to Continue Growing

According to the latest research, the American disposable medical supplies market (which includes contact lenses and related products) will continue to rise and its value will increase substantially by 2016.

Daily disposable contact lenses are listed among the products that will gain the most popularity. The other ones include blood glucose test strips, dry powder inhalers, urinary catheters, biological wound closures and transdermal patches.

The largest companies operating on the market are Johnson & Johnson and 3M Company, which manufacture various medical devices and materials.

The reason for the continuous growth in the sector is ageing population, increasing incidence of many diseases and the extended health insurance coverage which was introduced by the Affordable Care Act of 2010. Stricter measures related to infection prevention also promote the sales of disposable medical supplies.

Daily disposable contact lenses are less popular in the United States than in other developed countries, which means that there is considerable growth potential in this sector of the market.
