Not only their eyesight is good (even at an elderly age), but also their spirit is fresh. This module will consider the physics of light; moving from basic light as a ‘ray’ optical properties such as reflection and refraction, lenses, mirrors and prisms through to ‘light as a wave’ optics and diffraction, interference and polarisation. After the eye is numbed, it needs to be immobilized for the surgery. The cataract in one eye may be more advanced than the other, causing a difference in vision between eyes.
Age-related macular degeneration is a condition which affects the macula in the centre of the retina.
