Device for measuring aberration refraction of the eye |
| abstract |
An instrument for measuring aberration refraction of an eye is provided, having a lens system defining an instrument optical axis, and an alignment device for aligning the visual axis of the eye with the instrument optical axis. A light source (1) produces a probing beam that is projected through the lens system parallel to the instrument optical axis, and is selectively positioned partially offset from the instrument optical axis for entering the eye (15) parallel to the instrument optical axis at a plurality of locations on the cornea of the eye. A photo-detector (19) measures the position of probing beam light scattered back from the retina of the eye to measure aberration refraction of the eye at a plurality of locations. |
