A Study of the Effectiveness of CK One-Step Lenses for Correcting Myopia

Myopia (nearsightedness) may be corrected by using non-surgical and surgical techniques. Orthokeratology, the practice of wearing rigid contact lenses during waking hours, has been used to reduce myopia with minimal success. Recent advances in corneal mapping and contact lens technology have greatly improved lens fitting techniques. In the present study Precision Ocular Technology’s CK “One-Step” lenses were used to mold the corneas of 17 myopic patients. The subjects wore the lenses while sleeping in an effort to decrease their need for corrective lenses during waking hours. Each subject’s eyes were checked on days 1, 7, 30, and 60 after lens fitting for visual acuity, refractive error, corneal topography, and intraocular pressure (glaucoma test). Post-fit measurements were compared to initial values. Patients were surveyed after 60 days to assess comfort and satisfaction with the procedure. Fourteen patients completed the study through day 30 and had significant corneal flattening an
