Poseyedon Contact Lenses

Frequently Asked Questions

​​​​​​​What is the posEYEdon scleral lens?

posEYEdon is a contact lens customized for your eye and fabricated from FDA-approved Gas Permeable material.

How does posEYEdon differ from other contact lenses?

Soft lenses are larger than your cornea and are a combination of fluid and plastic. They drape over the surface of your eye and are comfortable to wear, not because they are soft but because they are large and move minimally when you blink. The fluid content may decrease throughout your wearing time which is why some experience dryness at the end of the day. Conventional gas permeable lenses (sometimes called “hard”) are smaller than the size of the cornea and often move every time you blink. It’s this movement that is difficult to adjust to for some people. The posEYEdon lens vaults over the cornea and is supported by the white portion (the sclera) of the eye. With a posEYEdon lens, the space between the back surface of the lens and the front surface of the cornea is filled with sterile, preservative-free saline solution providing moisture to the eye.

Why are posEYEdon lenses so comfortable?

Because the posEYEdon lenses fit under the eyelids, there is minimal lid awareness when blinking as the eyelids pass over the smooth surface. Most importantly, there is no to minimal movement of the lens, which also decreases awareness.

Who are posEYEdon lenses for?

posEYEdon lenses are for anyone looking for the freedom of contact lenses that provide clear vision while maintaining ocular health. These lenses are extremely versatile and can be fit when soft lenses have failed in the past. They are especially beneficial for those who are not achieving the desired level of vision with their current soft contact lenses. posEYEdon lenses are custom fit to your eye by an approved posEYEdon fitting center, staffed with professionals highly proficient in prescribing this lens for you if indicated.

I have high astigmatism - is posEYEdon for me?

A posEYEdon lens is a great option for patients with astigmatism. IT can provide more accurate and consistent correction of astigmatism, providing vision more similar to glasses compared to standard soft toric lenses.

How does the posEYEdon keep my eye moist?

The fluid layer beneath the lens provides a hydration chamber that lasts all day long, creating an optimal environment for the ocular surface. Additionally, the lens protects the eye from environmental conditions.

I have dry eyes. If I wear posEYEdon lenses, will I be able to stop using eyedrops and/or other medication for my dry eyes?

posEYEdon lenses provide extra hydration and protection for the eyes and are a great option for patients with all levels of dry eye. Wearing Poseyedon lenses may help reduce or eliminate the need for other dry eye therapies, such as using rewetting drops regularly.

Are posEYEdon lenses more expensive than the soft lenses I have tried in the past?

No, the annual costs are comparable to that of daily disposable soft lenses. Consult your certified posEYEdon Fitting Center for pricing details.

How long will a posEYEdon lens last?

Depending upon your tear film’s tendency to coat the lenses and your care habits, posEYEdon lenses should last approximately as long as gas-permeable lenses. We recommend annual visits to your posEYEdon Fitting Center eye care professional to determine efficacy.
