How do we troubleshoot small contact lens issues?

Here at our office, we use a highly advanced piece of technology called an OCT (optical coherence tomography) to image small areas of any contact lens where a patient is having issues. This helps us to problem-solve issues patients may be having with fogging, dry eye, or overall lens comfort.

The photo below shows the edge of a scleral lens. This patient reported "dryness" with their scleral lens and said they could "feel the edges". Over the course of the day, this became uncomfortable.

Optical coherence tomography (OCT) scan of patient wearing scleral lens. Patient was experiencing discomfort, which turned out to be loose edges on the lens.

We put a dye called fluorescein over the lens and watched it flow under the lens. This means the edges are too loose. He should not be able to feel the lens or have extra dryness.

We are going to tighten the edges of this lens so they round out closer to the eyeball. This will help him feel less dry and more comfortable. It also decreases fogging under the lens.
