App Description

Would you love to take all the work out of designing gas permeable (GP) contact lenses, converting glasses prescriptions to contact lens powers, or performing those annoying calculations and conversions that are so commonly used? Contact Lens Assistant (GP) will do it all!

Use the Empirical GP function to generate and edit both sphere and toric GP contact lens designs. Or, if you prefer a diagnostic fitting set, use the Diagnostic GP function to enter clinical data, then generate and edit a sphere GP design. All calculations and compensations are done for you (vertexing, base curve and power adjustments, etc), allowing you to avoid the distractions of annoying math equations and algorithms. You can change units at any time, and enter plus or minus cylinder refractions, depending on your preference.

If you're a student, resident, ophthalmic technician, optometrist or ophthalmologist, you won't want to live without this app!
