Yes. Some patients don’t know that they have to use a special type of solution to fill the bowl of the lens. It’s very important to fill the bowl of the lens with something that does not have preservatives.
A lot of times patients will come in, and they’re filling the bowl of the lens with saline, but it’s not preservative free. That’s an issue because that solution can become toxic to the eye. There are many types of effective and valid solutions for scleral lenses. Currently, there’s scleral fill, there’s lacquer pure, there’s neutrophil, and there’s non-preserved saline.
The bottom line, though, is that you should only use solutions your doctor recommends. Using any other solution may cause serious complications that can lead to injury or infection.
