BYO Premium KC
A custom soft silicone hydrogel contact lens for keratoconus.
When RGP lenses for medical use do not offer the right solution, the BYO Premium KC lens is an excellent alternative. The soft silicone hydrogel material guarantees optimal oxygen permeability. This makes the lens particularly suitable for medical use.
Features of BYO Premium KC:
- Stable vision
- Easy fit thanks to Flex Zones
- Optimal thickness distribution
The BYO Premium KC soft custom lens is designed for people with irregular corneas. When the cornea is deformed or damaged, traditional contact lenses and eyeglasses are often unable to improve visual acuity. BYO Premium KC has so-called Flex Zones in the periphery that make the lens easy to adjust on the irregular cornea.
BYO Premium KC can be worn daily for a period of three months. We recommend replacing the lens every three months.
Before using your soft lenses, always read the package insert that is provided by your contact lens specialist.

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.
