Steep GP Lens Correction: If we see a steep GP lens, what change should be made to the sagittal height of the lens?

A steep GP lens means its curvature is tighter than the cornea, giving it a greater sagittal height. That causes the lens to sit closer and bear more on the cornea, often reducing tear exchange and limiting movement. To correct this, you reduce the sagittal height by selecting a flatter lens (smaller sag). Increasing sagittal height would tighten the fit further, and not changing it would leave the steep fit unresolved.
