Comfort XL | Single Vision

Design

  • Large diameter for increased comfort and centration.
  • Corneal-scleral lens design
  • Solves most all GP and Soft lens fitting issues
  • The obvious go-to lens.
  • Manufactured in Contamac Optimum material.

Candidates

  • Patients with chronic 3-9 staining
  • Astigmatic patients who have unsuccessfully tried wearing a spherical lens.
  • Patients who are not completely satisfied with soft toric comfort and acuity.
  • Patients who are GP intolerant or have a sensitivity to wearing contact lenses

  • Diameter - 11.0mm
Comfort XL Fitting Guide
Lens Type | Single Vision
Diagnostic Lens Color | Green
  1. Select the diagnostic lens closest to the flat K. The base curve should be adjusted steeper or flatter until an alignment fluorescein pattern is noted centrally across the flat corneal.
  2. Ideal vertical movement of 2-3mm is imperative to achieve a healthy, comfortable fit.
  3. The ideal lift of the Comfort XL design should exhibit peripheral clearance when the lens is resting in its primary position (slight superior). If the .12 (average) edge lift of the diagnostic lens exhibits peripheral impingement, a .14 edge lift should be ordered. If the .12 edge lift diagnostic lens exhibits excessive clearance, a .10 edge lift should be ordered.
  4. The lens power can easily be calculated empirically by refraction over a diagnostic lens.
