In a recent article published in the September edition of Contact Lens Spectrum, Greg W. DeNaeyer, OD talks about the scleral shape and its application for scleral lens fitting, and how the understanding of scleral shape is key when efficiently designing customized lenses. The article reviews the advances in technology, like the sMap3D, and the research that has increased our knowledge of scleral shape.
Read about how we can use this knowledge to improve scleral lens fitting efficiency and success.
“Practitioners use diagnostic lens fitting sets to design most scleral lenses. We adopted this process early on, because none of our instrumentation could measure enough of the anterior ocular surface to translate to scleral lens design. For fitting purposes, practitioners often use scleral diagnostic lenses to determine primary parameters including the lens sagittal depth, which allows for corneal clearance, and the characteristics of the landing zone. Modern manufacturing allows landing zone designs.”
