Senso KC is an RGP lens suitable for different stages of keratoconus. Senso KC has no visible transitions. Thanks to its progressive design and Comfort Edge Design, this lens offers excellent comfort and movement. The front of the lens is made with AB technology, which creates perfect optics.

Features of Senso KC:

  • First choice in keratoconus
  • Progressive aspherical inner geometry
  • Comfort Edge Design

The Senso KC lens is specially designed for use in mild to advanced keratoconus. Keratoconus is an abnormality of the cornea. In this process, the cornea changes from its standard round shape to a pointed (cone-like) shape. This shape makes regular contact lenses not fit properly anymore. A qualified optometrist, ophthalmologist or contact lens specialist can diagnose this condition.

The Senso KC lens can be worn daily for up to one year. We recommend that this lens be replaced annually. 

Before using your RGP lenses, always read the package insert that is provided by your contact lens specialist.

To properly clean, disinfect, store and insert your Senso KC lenses, we recommend Ever Clean Plus or GP Multi in combination with the GP Cleaner.

The Ever Clean system is suitable for all lens types and is free of preservatives. It consists of a disinfectant based on 3% hydrogen peroxide combined with an innovative dual-focus effervescent tablet that provides thorough lens cleaning, disinfection, neutralization and moistening in just 2 hours. Unlike the standard Ever Clean liquid, povidone and lipase have been added to Ever Clean Plus. Povidone is an effective and long-acting humectant that contributes to the stability of the tear film. The enzyme lipase is effective against lipids that adhere both centrally and at the edges of the lens surface, contributing to thorough lipid cleaning.

GP Multi is an all-in-one liquid made specifically for RGP lenses. The component poloxamer ensures a clean lens surface and prevents microorganisms from adhering to it. Two types of humectants (HPMC and PVP) enhance the wearing comfort of the lenses. In addition, GP Multi provides an extra protective and comfortable layer around the contact lens.

GP Cleaner has a highly effective cleaning action that removes the most stubborn deposits. This non-ionic cleaning solution contains particles that eliminate lipids that adhere to the surface of the contact lens. GP Cleaner must always be used in conjunction with GP Multi.

Frequently Asked Questions

  • Which contact lens is best for my eyes?

    It depends entirely on you and your eyes. During an eye exam an eye care specialist assesses your eyes and looks at the strength and shape of your eye, among other things. You personal situation is also evaluated: When do you want to use them? How often? In what work environment? Based on all the measurements, you can choose the best lenses together with the specialist. Visit your nearest optician for an eye exam or consultation.
  • How do I clean my lenses?

    It is important to clean your contact lenses daily. The moment you remove your lenses, it is important to clean, rinse and disinfect them with the recommended lens solution as prescribed or advised by your contact lens specialist. Contact lens cases should also be emptied, cleaned and rinsed daily, as they can be a source of bacterial growth. Importantly, lenses, lens cases and other lens-related products should not come into contact with (tap) water because of the increased risk of microbial keratitis.
  • What should I look for in lenses for my child?

    Children can wear lenses as young as 8 years old on average.
