The Senso Semi Scleral lens offers the best of both worlds. The weight of the lens is divided between cornea and sclera, resulting in crisp and clear vision and good wearing comfort. A unique feature of the Senso Semi Scleral lens is that it is available in peripheral toric and bitoric. These are also available as multifocal.
Senso Semi Scleral lenses are indicated as an alternative for corneal contact lenses. For example in case of sensitive eyes and when soft contact lenses do not provide sufficient visual acuity.
The Senso Semi Sclera can be worn daily with a maximum of up to a year. It is advised to replace these lenses every 12 months.

To rinse, disinfect, store and apply your Senso Semi Sclera lenses, Ever Clean or GP Multi in combination with GP Cleaner is advised.
Ever Clean consists of a disinfection solution based on 3% hydrogen peroxide in combination with a bipartite tablet. The tablet consists of a green and a white layer. The white layer immediately starts cleansing and, reinforced by the ‘SELF-ACTION’ effect, removes protein. Simultaneously, the green layer arranges the delayed neutralization and extension of the hydrogen peroxide disinfection process.
GP Multi is an all-in-one contact lens solution especially suitable for RGP contacts. It contains a substance called Poloxamer that ensures a clean lens surface and prevents micro-organisms from atteching to this surface. Two moisturizers (HPMC and PVP) increase the wearing comfort of the lens. Additionally, GP Multi provides an extra protective and comfortable layer on the lens.
GP Cleaner is very effective, removing even the most persistent proteins. The non-ionic cleanser contains parts that eliminate lipids attached to the contact lens surface. GP Cleaner must always be used in combination with GP Multi.
