During our research with the translucent eye patch above, we experimented and did a formal visual field study on 60 eyes to see if the patch had to be attached to the patient’s head over their eye as had been done since the inception of visual field testing. We found that by using our translucent diffuser and placing it on the visual field machine rather than on the patient’s head, it improved visual fields and visual field testing in 18 ways without the need of an eye patch! Our device was so successful that Haag-Streit of Switzerland, the world’s largest manufacturer of professional ophthalmic equipment, incorporated our Corrales/Karickhoff Diffuserwith their Octopus 600 visual field machines, the most popular machine in the world.
