Polarization filtering for improved eye imaging

A laser procedure system comprising:

• an optical device comprising:
• an incident light polarizer positioned to polarize incident light that is directed to a cornea and a retina of a subject, wherein the polarized incident light has a first polarization;
• at least one corneal light polarizer positioned to polarize corneal light reflected from the cornea to obtain attenuated corneal light and polarize retinal light reflected from the retina to obtain attenuated retinal light, wherein the attenuated corneal light has less intensity than the attenuated retinal light;
• a first rotating mechanism coupled with the incident light polarizer so as to adjust a polarization of the incident light to direct to the cornea and the retina;
• at least one second rotating mechanism coupled with the at least one corneal light polarizer;
• and
• at least one viewing port optically coupled with the at least one corneal light polarizer;
• an eyepiece adapted for association with an eye of the subject;
• and
• a laser module optically coupled with the eyepiece,
• wherein the first rotating mechanism includes a rotation gear and a drive gear, the rotation gear having an aperture to which the incident light polarizer is coupled, the rotation gear being operably coupled to the drive gear, the drive gear being operably coupled to a drive shaft.
