Handling Molds

Molds look like GP contact lenses. They even have power so you can see clearly when they are on, like a contact lens. But unlike a contact lens, they are a medical device designed to alter the shape of the eye. Modern-day orthokeratology molds are intended to be used for sleep time only.

Hands must always be washed and dried prior to handling

Molds must be rinsed with preservative free saline solution prior to insertion

Molds must be filled with preservative free solution

Molds should be inserted upwards, with the patients face down

Molds should be removed with a special rubber suction device, or with fingers after properly trained.
