Doctor uses iPhone 13 Pro’s Macro camera to check patients’ eyes

The iPhone 13 Pro and iPhone 13 Pro Max are Apple’s first smartphones to support Macro photos. These are photos taken at a distance of two centimeters or less from the subject.

Apple says that "users can capture sharp, stunning images where objects appear larger than life, magnifying subjects with a minimum focus distance of 2 centimeters. Macro also extends to video including Slo-mo and Time-lapse."

A doctor has been found to use the Macro mode of the iPhone 13 Pro series to examine his patients’ eyes. According to a post on LinkedIn, ophthalmologist Tommy Korn said he used the iPhone 13 Pro Max to take Macro photos of his patients' eyes, which allow him to discern useful details about their health.

Dr. Korn wrote, "Been using the iPhone 13 Pro Max for MACRO eye photos this week. Impressed. Will innovate patient eye care & telemedicine. forward to seeing where it goes… Photos are from healing a resolving abrasion in a cornea transplant. Permission was obtained to use photos."

Furthermore, Dr. Korn used the CareKit service to create an app called Sharp Health Companion that sends reminders to patients through the Apple Watch. He was sending medication reminders and messages about their care through the Apple Watches on their wrists.

The Doctor wrote, 

Some people feel notifications can be bothersome especially in our busy and sometimes chaotic world - however, when your wrist notifies you of your health and medical well-being, these notifications no longer become annoying. It's your life at risk and everyone pays attention.
