Fitting Corneal GPs is Easier Than You Think

February 4, 2025 by Metro

Simple & Straightforward

Getting started is easy – no diagnostic fit set is required for most Metro Optics GP lens designs.

Note: Keratoconus can be fit empirically, but chair time is reduced by using a diagnostic set. We offer a complimentary ComfortKone Quick Fit Set. Learn more here.

Order GP lenses empirically, without any lens design calculations. Simply send the following patient information to consultation.

Exam Information

  • Corneal Topography
  • Keratometry Readings (Auto-K works well)
  • Manifest Refraction
  • Pertinent Patient History (surgery, trauma, past contact lens wear)

This information helps us understand the corneal shape & curvatures we are attempting to fit. If you don’t have a topographer, that’s okay!
