El repte/The challenge
Retinal image quality is the first limit to human visual performance, being affected by aberrations and scattering. The contribution of the latter has a great impact since it reduces the contrast of the retinal image and produces loss of vision, which is manifested in different diseases such as cataracts and some corneal disorders. Laser refractive surgery and intraocular lenses implantation can also increase the level of scattering.
La tecnologia/The technology
The system is based on recording images of the reflection on the ocular surfaces (Purkinje Images) of the light coming from an object, preferably opaque, which includes areas that allow light to pass to a greater or lesser degree, so that light is received in the eye in a series of clear and dark distinct areas. The analysis of the contrast in the Purkinje images, mainly P3 (reflection on the anterior surface of the crystalline lens) and P4 (reflection on the posterior surface of the crystalline lens), allows quantifying the intraocular scattering due to both the cornea and lens.
Avantatges innovadores/Innovative advantages
- Assessment of the scattering due to the cornea and the crystalline lens separately.
- Non-invasive and objective measurement.
- Can be incorporated to an existing device as a module or implemented as a stand-alone instrument.
