Abstract:Introduction: Scleral contact lenses (SCLs) are gas-permeable and are placed entirely on the sclera without contacting structures such as the cornea or limbus. These ECLs are designed to rehabilitate reduced vision of eyes with irregular corneas. Irregular astigmatism caused by corneal pathologies such as keratoconus, post-transplant, post-refractive surgery, or corneal degeneration produces poor visual acuity that cannot be corrected with air lenses, and the appearance of scleral contact lenses could be a the… Show more
