OmniMed II: a new system for use with the emphasis erodible mask.
Clinical experience has shown the emphasis erodible mask to be an effective method for performing photorefractive keratectomy (PRK) using an eyecup placed in contact with the corneal surface. A new system (OmniMed II) which incorporates the erodible mask as an element in the optical delivery system has been developed for performing photorefractive keratectomy. With this new configuration the eyecup is no longer used. We describe in detail the advantages of the erodible mask, the associated hardware of the optical delivery system, and the mask shape transfer process.
