S-lim: The Semi-Limbal Solution
First introduced in 2002, the original concept of the S-lim (Semi-limbal) lens was to provide a stable, comfortable alternative for keratoconic patients who struggled to settle into standard corneal lenses, but did not require a full scleral design.
Since its launch, the clinical applications of the S-lim have expanded significantly. Today, it is a trusted problem-solver utilised across a diverse range of complex fittings in hospital clinics and specialist practices, including:
Since its launch, the clinical applications of the S-lim have expanded significantly. Today, it is a trusted problem-solver utilised across a diverse range of complex fittings in hospital clinics and specialist practices, including:
- Irregular Corneas & Keratoconus: Providing excellent centration and apical clearance.
- Trauma & Corneal Disturbance: Restoring vision following ocular surface injury.
- Post-Surgery Management: Offering stable tracking over altered corneal geometry.
- Corneal Lens Intolerance: Delivering the crisp vision of a corneal RGP with the exceptional comfort of a larger-diameter profile.
Bridging the gap between corneal and scleral lens designs
The S-lim is engineered to give practitioners precise control over the physical fit and tear dynamics:
- Tailored Sizing: Available in flexible overall diameters ranging from 13.50mm to 14.75mm.
- Advanced Oxygen Transmissibility: Manufactured in two high-performance materials—70 DK and 120 DK—to ensure optimal, long-term corneal health.
- Zonal Edge Customisation: A major clinical advantage of the S-lim system is that each individual peripheral curve can be adjusted steeper or flatter to perfectly match the ocular topography. For example, the landing scleral curve can be maintained at a standard format while intermediate peripheral zones are micro-adjusted.
- Reverse Geometry Configurations: To accommodate post-graft/post- keratoplasty patients, the S-lim portfolio includes specialised reverse geometry formats specifically designed to span oblate corneal profiles.
Technical Versatility & Parameter Control
Comfort and Stability for an Active Lifestyle
Do you play sports but struggle with your current contact lenses? Whether your lenses frequently dislodge, attract dust, or cause irritating dryness during activity, you don't have to compromise on your vision or your performance.
The S-lim contact lens features a slightly larger, specialised semi-limbal design that tucks securely under the eyelids. This keeps the lens incredibly stable on the eye, locks out dust and debris, and provides exceptional all-day comfort—even during intense physical activity.
Speak to your eye care professional or contact lens practitioner at your next
appointment to find out if the S-lim is the right fit for your lifestyle.
