All of my patients have technician-guided topography and OPD-Scan III performed as part of a comprehensive eye examination. I then review the data with the patient in the examination room, making sure to connect any anomalies to his complaints. Having topography data available for every patient has shown me many cases of corneal conditions that I might not have detected otherwise. I’ve even saved marriages with it. A 60-year-old truck driver had a chief complaint of nighttime glare that was shaped like a cross. His wife thought he was making it up, but I was able to show her a point-spread function map that clearly demonstrated the cross-shaped glare that was being generated by the patient’s cataracts.
