In the January 2023 edition of Investigative Ophthalmology and Visual Science, Maria Walker et al. examined scleral lens midday fogging (MDF) in 26 eyes of 13 neophyte Europa scleral lens wearers. Quantification of MDF was achieved by analyzing AS-OCT images. Samples of the fluid reservoir were analyzed by liquid chromatography-tandem mass spectrometry. Read more about her findings here.
Why do patients experience scleral lens fogging? Despite the fluid reservoir being a closed environment, a commonplace occurrence among SL wearers is midday fogging (MDF) where debris builds up and become trapped within the FR. It has been reported that up to 46% of patients fit with SLs demonstrate MDF. (1) Many patients and practitioners experience this phenomenon at some point throughout the fitting process which may or may not be resolved with subsequent lens remakes.
As a Scleral lens practitioner, you know that scleral contact lenses are an attractive treatment option for patients who have struggled to find a comfortable lens fit in the past. But, patients must take special care of their scleral lenses, washing their hands thoroughly and filling the bowl of each lens with a nonpreserved saline…
