I have been hearing alot about new content lens from Viscon.
I currently wear a Jupiter lens- sometimes called semi-scelreal because it is much small than large sceleral contact lens.

The Jupiter Scleral falls into 2 main design categories- the 15 mm diameter (mini-scleral) series and the 18 mm diameter series. Both series are true scleral lenses sharing the characteristics that they 1) Bear on the Sclera and 2) Vault the Cornea. A lens that bears on the cornea in any way is not a scleral lens although it may be a corneo-scleral or semi-scleral lens.

The Jupiter 18 mm series is designed to be a semi-sealed lens and does not need to closely contour the cornea. The scleral portion is designed to allow adequate tear exchange but hold a much larger volume of tears. It can address the most irregular and asymmetric corneas as well as provide a large tears for severe dry eye cases.

The Jupiter 15 mm series lens requires a closer contouring to the cornea as the scleral contact is less and the capillary forces must maintain an intact tear layer to prevent bubbles and corneal dessication. The lower volume of tears means tear exchange must be more frequent to prevent a toxic buildup under the lens.
