In my clinic, cataract planning used to require stacks of paper charts filled with diagnostic printouts. My staff would compile biometric data—axial length, keratometry readings, posterior corneal values—from multiple machines, and I would then retype that information into IOL calculators, sometimes multiple times. Each calculator—post-LASIK, toric, astigmatic incision—required separate manual entry. Not only was the process tedious, but it also created opportunities for transcription errors.
