SpecialEyes 54 Multifocal Fitting Guide

for designing and prescribing custom soft multifocal contact lenses

Step 1: Obtain patient Ks, manifest Rx, HVID (if possible), add power, and pupil size. 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 54 Multifocal contact lenses for you.  If you prefer to design the lens yourself, use the SpecialEyes Arc Length Calculator or Prescribing Nomogram to determine the base curve and diameter of the multifocal contact lens,

Step 3: Contact the SpecialEyes Consultation Department or use the online SpecialEyes Multifocal Simulator to determine the multifocal zone sizes. Near center lenses OU is recommended as a starting point. The size of the multifocal zones will be determined by the patient's pupil sizes in ambient/regular room illumination.  Success is dependent upon accurate pupil size measurements.

Your trial 54 Multifocal contact lenses will arrive in 2-4 business days

Step 4: Evaluate on-eye performance of the trial multifocal contact lenses. Assess fit and visual acuity at both distance and near. If these are acceptable, dispense the lenses and allow the patient to adapt. Re-evaluate the lenses at the next follow-up visit. If performance is acceptable, your successful trial lenses become the first 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 order remake trial lenses based off of your multifocal contact lens fitting evaluation results.

Provide details on fit of lens, binocular visual acuity at distance and near, monocular visual acuity at distance and near, and over-refraction results. The center-zone size, aspheric power progression, peripheral zone, fit, and power of the 54 Multifocal contact lens can be altered to assist in meeting each patient’s specific distance and near visual-acuity needs.
