A scleral lens, also known as a scleral contact lens, is a large contact lens that rests on the sclera and creates a tear-filled vault over the cornea. Scleral lenses are designed to treat a variety of eye conditions, many of which do not respond to other forms of treatment.
Although Louis J. Girard invented a scleral contact lens in 1887, it was German ophthalmologist Adolf Gaston Eugen Fick who in 1888 fabricated the first successful afocal scleral contact lens. Approximately 18–21 mm (0.71–0.83 in) in diameter, the heavy blown-glass shells rested on the less sensitive rim of tissue surrounding the cornea and ...
In 1888, he constructed and fitted what was to be considered the first successful model of a contact lens: an afocal scleral contact shell made from heavy brown glass, which he tested first on rabbits, then on himself, and lastly on a small group of volunteers. It was considered the first successful model of a contact lens.
The sclera, [note 1] also known as the white of the eye or, in older literature, as the tunica albuginea oculi, is the opaque, fibrous, protective outer layer of the eye containing mainly collagen and some crucial elastic fiber. [2] In the development of the embryo, the sclera is derived from the neural crest. [3]
Using methyl methacrylate, the partners pioneered a new type of contact lens. Wesley and Jessen worked to develop the plastic lenses known as the rigid corneal contact lens. The corneal lens fit floated on the cornea, unlike its scleral predecessor, which rested on the sclera or white of the eye and bridged the cornea.
In 1986, he developed a practical, gas-permeable scleral contact lens to treat and restore vision of eyes with many corneal diseases, which ave been widely adopted in clinical practice, He has also published on oculofacial pain, and dry-eye disease.
