What is the purpose of adapting the nerve ending on the lid margin to GP lenses?
What is the purpose of adapting the nerve ending on the lid margin to GP lenses?
- To maintain exposure of the limbus
- To allow the patient to get used to the GP lenses (correct)

- To decrease tear exchange under the lens
Why is it important for the diameter of the lens to cover the entire cornea and go over the limbus?
Why is it important for the diameter of the lens to cover the entire cornea and go over the limbus?
- To prevent irritation of the limbal region (correct)
- To ensure exposure of the limbus which is good for eye health
- To allow for 0.5mm movement of the lens
- To diminish the limbal area ability to produce stem cells
What happens if a 14mm diameter lens is too large for a patient?
What happens if a 14mm diameter lens is too large for a patient?
- The edges of the lens will not sit properly under the upper and lower lid margin (correct)
- The lens will displace upward, exposing the inferior limbal region
- The lens will not adapt to the patient's eye
- The patient will experience air bubbles in areas where base curve is excessively steep
