Corneo-scleral lenses and semi-scleral lenses are much larger larger than conventional GP lenses and rest near the junction between the cornea and the sclera. Mini-scleral lenses vault over the entire corneal surface and rest on the anterior sclera The lens is designed to fit as a semi-scleral lens, overlapping the limbus by about 1- 1.5 mm. The central optical radius (Base Curve) should be selected utilizing the fitting set, such that it is preferable to have a minimum central touch. In the case of Keratoconus patients it is essential to minimize, but not eliminate any central touch The smallest sclerals are approximately 14.5 mm in diameter, and the largest can be up to 24 mm. Large-diameter scleral and semi-scleral GP lenses rest on the sclera and vault over the misshapen cornea of a person with keratoconus, for better vision. Typically, lenses that are 18 mm or smaller are subcategorized as mini-sclerals

  1. It's been a year now since I tried wearing a type of Semi Scleral lens it's a 14MM lens, so larger than most soft lenses, but not as large as a full-scale scleral. It's like a really large RGP in a way
  2. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. These larger lenses also are more stable than conventional gas permeable contact lenses, which move with each blink because they cover only a portion of the cornea
  3. Semi-scleral contact lenses are considered corneo-sclerals (Table 1). Scleral contact lenses may also be defined by their fitting characteristics. Nomenclature for scleral lenses is undergoing development. Discussion over what exactly is a semi-scleral lens, for example, or how to define a corneo-scleral lens is ongoing
  4. Option Number 1 - Corneo-Scleral or Semi-Scleral Lenses This type of scleral lens rests near the junction between the cornea and the sclera, and covers a smaller portion of the sclera than occurs with full scleral lenses. Corneo-scleral (semi-scleral) lenses also typically have a smaller tear reservoir than full scleral lenses
  5. Semi-scleral lenses range in size from 13.6mm to 14.9mm. Because most contact lens fitters are comfortable with corneal GP lenses, there is a temptation to go just a little bit larger when first fitting scleral lenses

Unlike RGP contact lenses, scleral contact lenses include a reservoir for filling with sterile isotonic fluid that makes them more comfortable for keratoconus-afflicted people who have dry eye syndrome. Along with cornea pain, dry eyes are a possible keratoconus symptom that can preclude wearing RGP lenses for more than an hour at a time A semi-scleral contact lens which is easy to fit and which does not seal off the corneal area from the flow of eye fluids is desirable. Semi-scleral contact lens have been made from relatively rigid materials such as polymethylmethacrylate (PMMA) in shapes which do not take into account the topography of the individual eye OBJECTIVES: To evaluate the utility of the Rose K2 XL semi-scleral contact lens (Menicon Co. Ltd., Nagoya, Japan) in the management of the irregular cornea. METHODS: Twenty-seven subjects (34 eyes) with irregular corneas referred for contact lens fitting were evaluated. A diagnostic trial set was used in the fitting process Scleral lenses also come in smaller sizes, known as mini-scleral, semi-scleral, and corneoscleral lenses. Optometrists use these lenses for patients who might find they experience discomfort with regular GP lenses and need a larger size to provide the comfort they are looking for Corneo-scleral lenses and semi-scleral lenses rest up near the junction between the cornea and the sclera. On the other hand, mini-scleral lenses cover the whole corneal surface along with the entire anterior sclera. Full scleral lenses provide the largest amount of space between the back surface of the lens and the cornea

Jupiter Scleral Lens. Jupiter Scleral is where is all started for Visionary Optics. Originally designed in 2001 by Dr. Robert Breece, with diameters ranging from 15 to over 18.0mm, it was one of the pioneering designs that started the modern scleral lens industry. The Jupiter has been superseded by the easier-to-use, more advanced Europa. Corneo-scleral lenses and semi-scleral lenses are significantly larger than traditional GP lenses and rest near the junction between the cornea and the sclera. Mini-scleral lenses vault over the whole corneal surface and rest on the anterior sclera You can also use the WAVE contact lens design software to design a Scleral lens from a corneal topography map. In such case, the WAVE software uses extrapolated data to design the Scleral lens. After the initial fit, you can use the WAVE lens modification tools to adjust the design based on your clinical observations

Dr. Wilcox likes to break down the naming of these large RGP lenses based upon how they fit the eye.

Abstract: We presented a case of refractory dry eye management with semi-scleral contact lens. Dry eye was associated with facial nerve (cranial nerve VII) palsy as a result of cerebellopontine angle tumor surgery. She was treated with several topical treatments and punctal plug. Despite the treatments, her symptoms still persisted. Her ophthalmic examination revealed scleral exposure because. This semi-scleral lens is used for keratoconus, PMD, post-surgical, and any irregular corneal condition that cannot be successfully treated by fitting a lens within the limbus. The Rose K2 XL follows the same systematic fitting system that is advocated for the four other Rose K2 designs and is extremely easy to fit, even for fitters who have. The miraculous scleral lens.
