摘要

A kit for determining a hypothetical cornea for use with post-LASIK and post myopia Ortho-K amendment. The kit has a reference table for determining conformation data by using at least one of following data: pre-treatment KM readings, post-treatment KM readings, power reduced from before- to after-treatment, and post-treatment cornea optical zone. The kit further comprises a plurality of conformed lenses based on the conformation data in predetermined increments from the reference table. The pre-treatment KM readings comprise pre-operative or pre-ortho-K readings. The post-treatment KM readings comprise post-operative or post ortho-K readings. The post-treatment cornea optical zone comprises post-operative or post-ortho-K cornea optical zone. Also, a method of determining a hypothetical cornea for use with post-LASIK and post myopia Ortho-K amendment is disclosed. The method has inputting pre-treatment KM readings, inputting post-treatment KM readings, inputting power reduced from before- to after treatment, inputting post-treatment cornea optical zone, calculating conformation data, which is adapted to be used to generate specification for conformed lenses. Another kit for determining a hypothetical cornea for use with Keratoconus and post-hyperopia Ortho-K amendment can be constructed using at least one of following data: pre-altered KM readings, post-altered KM readings, pre-altered refraction error, and post altered specifications. The kit further comprises a plurality of conformed lenses based on the conformation data in predetermined increments from the reference table. The pre-altered KM readings comprise pre-keratoconus or pre-hyperopia ortho-K readings. The pre-altered refraction errors comprise refraction errors from a set of normal corneas. The post-altered specifications comprise cone widths of Keratoconus or steepened cornea zone of hyperopic Ortho-K and also magnitude of off centering of the cone apex.
