Orthokeratology (oprifocon A) Contact Lenses from Euclid Systems Corporation

The Euclid Systems Orthokeratology (oprifocon A) Contact Lenses are rigid gas permeable contact lenses used for orthokeratology, a process that temporarily corrects nearsightedness (myopia). The patient wears these lenses overnight and removes them in the morning. During the day, nearsightedness is temporarily corrected or greatly reduced.

The Euclid Systems Orthokeratology (oprifocon A) Contact Lenses apply slight pressure to the center of the cornea, causing it to temporarily flatten. The flattened cornea redirects light onto the back surface of the eye (the retina) at an angle that can compensate for nearsightedness. Since the cornea is elastic, it gradually regains its shape throughout the day causing nearsightedness to return. Usually, patients must wear the lenses every night to maintain corrected vision. When the lenses are removed each morning, they must be cleaned and disinfected using a chemical disinfection system.
