OPHTHALMOSCOPES

摘要

A scanning laser ophthalmoscope for scanning the retina of an eye is provided comprising a light source emitting a beam of light, scan relay elements, wherein the light source and the scan relay elements provide a two-dimensional scan of the light beam which is transferred from an apparent point source at a pupillary point of the eye to the retina of the eye, and a static aberration correction element (30) which has a shape defined to provide correction of aberrations of at least some of the scan relay elements and a location within the ophthalmoscope chosen to provide correction of aberrations of at least some of the scan relay elements, which location maintains transfer of the beam of light from the apparent point source at the pupillary point of the eye to the retina of the eye. The present solution further provides an aberration correction element and a method of determining a shape of the aberration correction element.
