How do I evaluate a scleral lens?
Often times I am asked to discuss scleral lens assessment. What do you look for? What equipment is needed? Any other advice?
Here is a short video of me assessing a scleral lens on a patient's eye.
First, I get an overall view of the lens to make sure there are no bubbles. I also evaluate the font surface for wettability issues or scratches or deposits.
Next, I have the patient look up, down, to the left, and to the right. This helps me evaluate the edges of the lens to see how the lens is interacting with the conjunctiva. After I take a look at the lens with the slit lamp, I will then check the central clearance and edges with an OCT machine.
