A cryo‐technique for production of corneal epi‐lenses has been developed. During the manufacturing procedure the anterior surface of the tissue is moulded and the posterior surface cut with a microtome. After cutting, the epi‐lenses are stored for days to weeks in an organ culture medium. Twelve eyes in 10 patients have been treated with epikeratophakia for high myopia (>–7D). In all eyes, epithelialization was complete within one week, and at follow‐up 3–18 months after the operation all epi‐lenses were clear. The average refractive change in spherical equivalents was 9.7 ± 4.4 D. All eyes obtained better uncorrected visual acuity, and no eyes lost more than one line of the best corrected visual acuity. At the time of follow‐up, the patients' native cornea had regained normal hydration, whereas the epi‐lenses did not thin as much as expected.
