Scleral Contact Lens Atlantis is a scleral lens design that performs well on any patient with an irregular cornea, including keratoconus, pellucid marginal degeneration, corneal transplants, post refractive surgery, post corneal rings, and ocular surface disease. Scleral lenses have also been utilized on regular corneas, dry eye patients, and athletes.   Download Insertion & Removal Instructions  What are Scleral Lenses? Scleral lenses are gas-permeable lenses ranging from 14mm to 20mm that completely vault the cornea, "land" and rest on the white part of the eye called the sclera, and create a reservoir of tears. Because of their size and this tear reservoir, they are typically extremely comfortable and at times may provide better vision correction than standard contact lenses, glasses, and even surgery. The Atlantis proprietary lens design was developed to provide a problem solving solution along with a simplified fitting system with the 1-2-3 fit strategy. The unique peripheral curve calculation will allow central clearance while providing good distribution of pressure in the landing area, adequate edge lift and overall superior comfort.     The white part of the eye is called the sclera and these lenses are designed to vault the cornea and be supported by the sclera with a fluid reservoir between the cornea and the contact lens.   Liquid Filled Vault Scleral Lens  Scleral lens vaulting the Cornea with a tear "cushion" The smallest lens will cover the entire colored part of the eye and will then extend a small amount onto the white part of the eye. The largest lens will continue to extend onto the white of the eye so that every part of the eye that is showing, and even some parts that are hidden by the lids, will be covered by this lens. Only the more oxygen-porous gas permeable materials are used to ensure an adequate supply of oxygen for the cornea.

An irregular cornea can be the result of a disease such as Keratoconus, corneal trauma, corneal transplant, and more recently refractive surgery. In many cases, the irregular cornea prevents the proper positioning of a corneal lens but a scleral lens can seat itself properly on the sclera and therefore be in the correct position on the cornea. The vision with a scleral lens as well as the other gas permeable corneal lenses can be vastly superior to glasses or soft contact lenses when considering irregular corneas. These lenses provide the optical system a new surface that provides great vision while neutralizing all of the irregular optics of the underlying cornea. For many people with irregularly shaped corneas, these types of lenses provide the only form of usable vision correction. Additionally, scleral lenses can address many contact lens failures that were secondary to dryness. Since Scleral lenses form a tear reservoir under the lens to keep the cornea properly moist, foreign matter and debris have a difficult time finding their way underneath. This fact can be the single entity that allows contact lens success while all other contact lenses have failed.
