Abstract:
Systems and methods for measuring dysphotopsia are provided. These systems and methods can be used to objectively quantify positive and negative dysphotopsia. One embodiment provides a system and method for determining dysphotopsia that uses a first light source configured to provide light energy to illuminate a model eye, a refractor for refracting the light energy from the first light source and directing it into the model eye, a first electronic light sensor for measuring an amount of light in the model eye; a second light source configured to provide light energy to illuminate the model eye, wherein the light energy from the second light source is introduced at an angle from the first light source; and a second electronic light sensor for measuring the amount of light in the model eye, wherein the second electronic light sensor is capable of taking measurements from various points around the model eye. Data from these measurements can then analyzed to provide an objective measurement of dysphotopsia.
