Scleral & Mini Scleral

The irregular cornea.Scleral lenses are most commonly prescribed in the case of corneal irregularity, which induces higher-order aberrations; it can result from keratoconus, corneal surgery or trauma, or complications of otherwise routine surgery. 

Such patients are often managed with corneal GP lenses; this modality’s ability to mask front surface corneal irregularity leads to dramatically improved vision. However, contact lens practitioners have struggled for decades to fit corneal GP lenses on patients with moderate to severe irregularity because of one inherent problem: the lenses’ small relative size forces them to distribute their weight directly onto the uneven corneal surface, which can lead to destabilization of the fit. Scleral contact lenses, on the other hand, vault over the cornea and rest on the sclera. As a result, centration and stability will remain unaffected.

Patients who have moderate to

• Severe corneal irregularity,
• Ocular Surface disease
• High Astigmatism.

Dry Eye etc. makes excellent candidates for scleral lens.
