A bit about our team...

Since 1988 Createch and Redher Development Company have been producing the best contact lens permeability test equipment available.

The Polarographic method for testing contact lens material was pioneered by Dr. Irving Fatt, which resulted in the ISO 9913.1 and ISO 9339.2 standards (ISO18369). Createch and Rehder Development Company (RDC) worked closely with Dr. Fatt to design the Createch 201T Permeometer, the Rehder Polarographic Cells and the Rehder Electronic Thickness Gauge. This equipment is now widely used by major contact lens manufacturing and research facilities around the world.

Our founding employees have over 35 year of experience in Vision Science Research. They have designed and produced many unique mechanical and electromechanical instruments. Much of the work has been to develop highly specialized one-of-a-kind equipment for laboratory use. In 2014 Createch and Rehder Development Company were combined in to a single company - Createch/Rehder Dev Co. At that time our main offices were moved to West Lafayette, Indiana. Under the direction of Tom Houck Createch/Rehder Dev Co continues the tradition of supplying high quality Vision Research Equipment to the scientific community.

Meet the team...

We stand ready to help you setup and operate a high quality testing environment.
