Shaping Lenses

 

Orthokeratology (Ortho-k)

Orthokeratology is the temporary reduction of myopia achieved by the programmed application of contact lenses to reshape the cornea.

Modern orthokeratology achieves this using specially designed reverse geometry gas permeable (GP) ortho-k shaping lenses worn during sleep. This overnight wearing process provides a faster, more predictable result than early ortho-k attempts as practiced in the 1980s using conventional, rigid contact lenses fitted incrementally flatter. Using this vision shaping technique, properly selected patients can go through the day wearing no correction and enjoy excellent visual acuity.
