Improved systems and methods for determining ocular scattering are provided. These systems and methods can be used to quantify ocular scattering before and/or after a wide variety of different ophthalmic diagnostic procedures, and various surgical and non-surgical treatments. One embodiment provides a system and method for determining ocular scattering that uses two light detectors, with one detector configured to detect light over a relatively narrow angular range, and the other detector configured to detect light over a relatively large angular range. The data from the narrow angular range and the large angular range can then be analyzed to determine a measurement of ocular scattering.
