A common surgical procedure involving new artificial lens technology by postgraduate researcher Devesh Mistry of the University of Leeds could soon restore people’s ability to focus on close objects, potentially making reading glasses obsolete.
The lenses would be made of liquid crystal, the same substance that is found in smartphones and television screens. This unique semi-solid, semi-liquid material would be able to adjust automatically to eye movement, restoring long-sightedness in people whose natural lenses have lost this ability.
It is common for older people to develop this condition, called presbyopia, because as people age, the muscular lenses of the eye lose flexibility and elasticity. If Mistry’s research remains on track, a liquid crystal lens surgery could soon become the more permanent solution to presbyopia. In addition to restoring long-sightedness, liquid crystal lenses could also help with cataracts, a condition involving the clouding of the lens.
Mistry aims to have a prototype of the liquid crystal lens completed by the end of 2018, and within a decade, he hopes that the lens will be commonly used in a quick and simple surgery in which the lens would be implanted into the cornea.
