Abstract

A rigid gas permeable (RGP) lens is good for correcting corneal astigmatism without inducing corneal hypoxia. However, despite the optical advantage of the RGP lens for correcting visual acuity, there may be circumstances in which a patient may choose not to wear the RGP lens. For example, because the RGP lens is smaller than the cornea, it may cause a foreign body sensation due to lens movement and blurring, especially at night. Thus, the success of the RPG lens prescription depends on the selection of the proper candidates and lenses, with appropriate fitting and follow-up management by a doctor.
