11. Scleral TroubleshootingCharl Laas

Air bubbles captured under the scleral lens is undesirable and will lead to wear discomfort and reduced acuity. There are two causes for captured air bubbles underneath the lens bowl:

Incorrect insertion technique**

Review the patient's insertion technique and make changes where necessary.

Uncorrected limbal toricity

Air bubbles can seep in underneath the steep meridian of a scleral lens with insufficient sagittal toricity fitted on a highly toric sclera.

Increase the SAG@15 value of the steep meridian, which will increase the SAG of the Z-Zone and lower the SLZ down onto the sclera effectively sealing of tear and air inflow underneath the steep meridian.
