What you’re looking at here is not just an image of an eye.
It’s a live, micron-level view of how modern technology allows us to design vision with precision.
This instrument is the ZEISS Visante OCT, a highly advanced imaging system that lets us see structures of the eye in cross-section, something that was impossible to measure accurately just a few years ago. Instead of guessing how a scleral lens fits, we can now visualize exactly how it interacts with the eye in real time.
A scleral lens is unique because it never touches the cornea. It vaults completely over it, creating a microscopic fluid reservoir that protects the surface of the eye while delivering clear, stable vision. The key is balance. The space between the back of the lens and the cornea must be measured in microns. Too little clearance can create pressure. Too much can affect oxygen flow and visual performance.
Here, you’re seeing my own eye with my scleral lens in place. The OCT shows approximately 300 microns of clearance, which is right where we want it. That precise distance is what allows the lens to remain comfortable, healthy, and optically stable throughout the day.
This is where technology meets personalized medicine. Every eye is different, and with imaging like this, we can design lenses based on data rather than approximation.
And when everything aligns correctly, patients don’t just see better. They experience vision in a way they didn’t think was possible.
