Researchers at EyeVis Eye and Vision Research Institute have reported positive results from the first year clinical trial. The trial is testing whether specialized contact lenses in the non-surgical overnight corneal reshaping process can slow or halt the progression of near sightedness in children. The specially designed contact lenses, when worn overnight in sleep, can change the shape of the cornea. The induced flatter curvature of the cornea results in clear vision, reducing or eliminating the dependence on contact lenses or glasses during waking hours.

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.

Dr Uday Devgan, a MD, FACS has offered some helpful points to succeed in the presbyopic IOL while going for Cataract surgery. The first thing to be done is post-op emmetropia with the use of precise lens calculations with either immersing ultrasound or the Zeiss IOLMaster, as well as personalization of the A-constant. Selection of the right kind of patients by understanding their expectations is the key to success. Sufficient care has to be taken so that complications are minimized. Producing clear corneas on post-op day 1 is important for patient satisfaction. This can be done by reducing the phaco energy placed into the eye and protecting the cornea with a good quality viscoelastic. Cleaning up the cortex can be done by silicone coated I&A tip. This avoids direct contact of bare metal of I&A tip with the delicate posterior capsule.
