Answer

To preserve corneal clarity after the visual reconstruction, the long-term use of gas-permeable scleral contact lenses may be necessary to protect the ocular surface. Large-diameter gas-permeable prosthetic lenses specifically designed to vault over the entire corneal surface and rest on the sclera have provided both comfort and better visual acuity in selected cases. A special liquid fills the space between the back surface of the lens and the front surface of the cornea. This liquid acts as a buffer and protects the compromised corneal tissue.
