The iDesign is the latest very high resolution wavefront scanner from AMO. There are now over a thousand wavefront scan points over the pupil, and effectively a sight test is performed at each location. This results in the ability to achieve greater precision than ever before with wavefront-guided treatment. Mr Stevens has been involved in the development of iDesign and Moorfields was the first eye centre in the UK to use iDesign technology.

iDesign employs a sophisticated wavefront measurement, similar to the laser technology used to examine the mirrors of the James Webb Space Telescope.
