Sh SoftK Semi Scleral
The SH Soft K has evolved by increasing the diameter of our SH Soft-K contact lens, for patients with keratoconus and corneal ectasia. The advantages of silicone hydrogel materials are well known.
High oxygen transmissibility and lower dehydration rate when compared to conventional hydrogels provide better support for normal corneal physiology. This is especially important when increased lens thickness is required.
The greater stiffness of these materials provide added value to lens surface regularization properties.
Due to the large lens diameter these lenses actually rest on the sclera and para-limbal cornea, which usually remains unchanged in keratoconus, with just a “feather” touch on the central protrusive area. Therefore, a fitting pattern that resembles a "minimal apical touch" of RGP contact lenses is achieved.
