Pentacam with CSP (Corneal Scleral Profiling)

This technology has been transformative for our practice and our patients. This tomographer scans the eye and measures the elevation and thickness of over 100,000 points. Why is this so helpful? There are many reasons. Just as no two fingerprints are alike, no two eye surfaces are alike either.

1. In the past, patients needing orthokeratology lenses, would receive lenses designed with just a few specified curves. This sometimes resulted in lenses that might not center or be as comfortable as possible. A lens that doesn’t center well may not provide optimal vision. Now that we can measure over 100,000 points, we can create lenses that line up with those points for better fit, comfort, and vision.

2. Historically our scleral lens wearers would have peripheral lens curves designed on an educated guess as there was no way to measure the curve of the sclera. Traditional corneal topography only measured the curves of the cornea. Now we have a way to measure the topography of the sclera. This allows us to base the peripheral curve system of the lenses on the actual curves of each person’s sclera. A truly custom lens.

3. Early detection of disease. The Oculus Pentacam measures corneal thickness throughout the entire cornea. The software associated with the instrument compares each person’s corneal thickness in each location to determine if they are in the early stages of corneal disease. This allows us to detect a disease like keratoconus years earlier than prior methods, which can result in earlier and more effective treatment, minimizing vision loss.

We are proud to be the only office on Seattle’s eastside with this technology.
