Scientists develop LED technique to help diagnose cataracts
Scientists at Heriot-Watt University have developed a new way to diagnose cataracts.They use LED (light-emitting diode) technology to measure cataracts at a molecular level.This gives clinicians a better idea of whether patients need to have surgery.About 10 million cataract removal operations are performed globally each year, and in the UK more than half of people who are over 65 have cataracts in one or both eyes.

In the later stages of cataract formation, patients commonly experience cloudy vision prior to treatment. It is also a recognised complication of Type 1 and Type 2 diabetes.It allows clinicians to monitor a florescence signal from proteins in the eye lens and document changes during cataract formation.
