SpecialEyes Sphere and Toric Fitting Guide

for designing and prescribing custom soft contact lenses 

Step 1: Obtain patient Ks, manifest Rx, and HVID (if possible).  If you are interested in learning techniques to measure a patient’s HVID, visit our How to Measure HVID page available in the learning center.

Step 2: Contact SpecialEyes and let us design the custom spherical or toric contact lens for you. If you prefer to design the lens yourself, use the SpecialEyes Arc Length Calculator or Prescribing Nomogram available in the Learning Center.

Step 3: Provide the lens design or exam parameters to SpecialEyes via phone, email, or fax:
Phone: 866-404-1060
Fax: 866-404-1030
Your trial spherical or toric contact lenses will arrive in 2 to 4 business days.

Step 4: Evaluate on-eye performance of the trial contact lenses. Assess fit and visual acuity. If performance is acceptable, your successful trial lenses become the first quarterly pair. You may then contact us (using any of the above methods) to order the remaining supply. To improve performance or fit, proceed to step 5.

Step 5: Contact a SpecialEyes consultant to report your initial sphere or toric contact lens fitting evaluation results.

Correct fit issues before attempting to alter power. If the fit is acceptable, perform sphero-cylindrical over-refraction and order a remake trial lens, which we will provide at no lens cost.

Step 6: Evaluate on-eye performance of remake trial lenses. If performance is acceptable, order the remaining supply or any quantity you would like. To further improve performance or fit,
repeat step 5.
