Final Thoughts

The practitioner has many parameters to choose from in deciding the optimal fit for a rigid lens. Although system-designed lenses are suitable for many, optimum comfort or visual acuity should not be compromised if an ideal fit cannot be achieved. Skilled laboratories can design lenses to exact specifications, if required. As with all contact lens practice, a systematic approach should be utilised. Changes to lens parameters should not be made unless there is a logical reason to do so.
