Australian researchers at the Moorfields Eye Hospital in London have conducted a study which reveals that the rate of corneal infection related to contact lens is 4.2 per 10,000 wearers per year. The scientists, in the first study of its kind, seek to describe the incidence of infection associated with the two new kinds of lenses introduced with the expectation of reducing the risk of infection — daily disposable soft lenses (launched in 1995), and silicone hydrogel lenses (launched in 1999). Planned replacement soft lens is better and safe for the eyes. The new age soft lens, Silicone hydrogel lens users who kept their lenses in overnight had the greatest disease incidence. But, proper use of daily disposable lenses made them the one with the lowest risk of a severe form of disorder as elimination of storage reduced the probability of contamination.
