I'm sure you can see the scratches on a poorly dilated pt though. Man! Tough luck.. You can always do the hot breath method w/a lens cloth which works pretty good and affordable. :) Best regards, Andy Sanchez, COA Ophthalmic Photographer 210-358-7631 Eye Clinic-TDI 701 S.

Specifically, how often do you clean the front objective lens, and what methods do you use? We recently discovered that one of our camera lenses was badly scratched from someone cleaning with something abrasive (seriously looks like it was done with sandpaper..thankfully it does not affect the image at all in most cases) Any other tips on camera cleaning and maintenance would be welcome! Thanks very much! Noelle Pensec Noelle Pensec Columbia University Medical Center Diagnostic Imaging Specialist (212) 305-0647
