A patient that I prescribed scleral contact lenses to can now see the craters on the moon.
Previously, Gene had less-than-great vision. He had corneal transplants and was wearing gas permeable lenses.
The lenses moved significantly. They often slid off the eye and became hidden under the upper eyelid. They also irritated his eyes. He could not comfortably wear them all-day. This impaired his day-to day activities.
Scleral lenses have changed his life! He wears his new lenses all-day, with great comfort, and has never seen as clearly as he does now.
