Use of Scleral Lenses in the Visual Rehabilitation of Keratoconus: A Case Series [PDF]

open access: yes, 2019
Introduction: Scleral lenses also known as scleral contact lenses are rigid gas permeable contact lenses that rest entirely on the sclera without touching the cornea.

Are people adapted to their own glasses? [PDF]

open access: yes, 2012
Negative lenses, either in the form of glasses or contact lenses, can correct nearsightedness. Unlike contact lenses, glasses do not only correct, but also induce optic distortions.

Contact Lens Visual Rehabilitation in Keratoconus and Corneal Keratoplasty [PDF]

open access: yes, 2012
Keratoconus is the most common corneal distrophy. It's a noninflammatory progressive thinning process that leads to conical ectasia of the cornea, causing high myopia and astigmatism.

Infectious Complications of Contact Lenses: A Review of the Literature [PDF]

open access: yes, 2023
The use of contact lenses is very common, they are prescribed for the correction of refractive errors that cannot be treated by glasses such as aphakia, keratoconus and strong anisometropia, or as alternatives to glasses. Contact lenses can cause serious
