See how choosing the right material combined with precision powers and parameters can equal success. [ SpecialEyes ](https://blog.specialeyesqc.com/author/specialeyes) Apr 19, 2016 --- Practitioners are frequently presented with patients who are unsatisfied with their current soft contact lens design. The reasons for this vary from patient to patient, but often lead back to poor comfort and/or vision. Prescribing the perfect soft contact lens design begins with a precision fit, in a bio-compatible, moisture retentive material. Fortunately, SpecialEyes’ custom soft contact lenses can achieve both. In addition to our wide power and parameter range manufactured with exceptional accuracy, SpecialEyes’ GMA-based materials provide natural wetness for excellent hydration. This allows our custom contact lenses to retain 97% of moisture throughout the day.

Her exam findings were as follows: **Keratometry Readings:** OD: Ks: 43.2/48.6 OS: Ks: 43.7/48.6 **Manifest Refraction** OD: -5.00 -5.50 x011 OS: -7.00 -5.00 x172 The initial trial toric contact lenses were designed using the [SpecialEyes Arc Length Calculator](https://calculators.specialeyesqc.com/arc-length-calculator.php). This contact lens calculator features a simple plug-and-play design and is a great tool for contact lens fitters to design their own SpecialEyes custom contact lenses utilizing a sagittal depth fitting philosophy. Based on the results from the calculator, the trial lenses were ordered with the following powers and parameters: **SpecialEyes 54 Toric** OD: 8.2 14.7 | -4.75 -4.50 x011 OS: 8.4 14.6 | -6.50 -4.00 x172 During the initial contact lens dispense, the SpecialEyes 54 Toric contact lens exhibited good centration, corneal coverage, and movement on blink. The patient took no over-refraction and yielded a binocular distance visual acuity of 20/20 with the first set of lenses. After allowing the patient to wear the lenses for about a week, the patient reported satisfaction. No remakes were needed and a supply of lenses was ordered!
