Corneal modifications are usually bilateral but asymmetric. Unilateral KC continues to be explained at fees of 0.five-4.five%, but with recent topography and corneal aberration measurement procedures, it's been noted that changes That could be affiliated with subclinical KC can even be detected inside the apparently ordinary fellow eye.
The PBCL process may be preferable for keratoconic patients who experience discomfort and intolerance, insufficient lens stabilization, or apical epithelial erosion with RGPCLs.

Mini-scleral lenses could be created thinner, which gives an advantage in terms of oxygen permeability. Lowered lens mass and fewer movement than bigger lenses make them much easier to tolerate.74 Mini-scleral lenses have lower corneal clearance in comparison to significant scleral lenses for the reason that with more compact lens diameter, the sagittal depth necessary for the lens to distinct the corneal apex decreases. It is usually recommended that corneal clearance must Preferably be between one hundred and three hundred µm inside the central zone. Small central clearance leads to increased oxygen transmission, greater Visible acuity, and fewer bubble development.
