Rigid gas permeable (RGP) contact lens fitting is very often thought of as being much more complex and involved compared to soft contact lens fitting. In reality, this is often not the case. RGP fitting today is an easier process and much more successful than the results obtained in the past. Practitioners now have access to lenses that can accommodate a wide range of the ametropic population, in addition, these lenses are easier to fit, initially more comfortable, and require less chair time. The most recent materials offer better wettability, greater stability and centration on the cornea, along with a more predictable and defined outcome? Developing a cyclic routine as per fitting soft contact lenses is recommended to ensure a full procedure is carried out efficiently. It is good practice to start the consultation with a general discussion with the patient, remembering to ask open, rather than closed, questions, as this generally promotes positive interaction with the patient, making it easier for the practitioner to elicit more valuable information. This second article in OT's four-part series continues with a discussion on patient selection, initial examination and general principles of use for successfully fitting RGP spherical lenses.
