Study Details

Study Description

Brief Summary

This is a multicenter study to evaluate the clinical performance of the SynergEyes A2 lens in patients with refractive errors with or without astigmatism.

Condition or Disease Intervention/Treatment Phase
  • Device: SynergEyes A2 Hybrid Contact Lens
N/A

Detailed Description

Hybrid contact lenses have been previously shown to be a safe and effective method to correct refractive errors with and without astigmatism. The hybrid contact lens design may provide greater visual acuity and comfort than other soft or rigid gas permeable (RGP) lenses currently available. The purpose of this study is to confirm the design of the SynergEyes A2 lens by evaluating clinical performance and, if necessary, modify certain lens parameters in order to optimize lens performance. Objective and subjective parameters will be used to evaluate the lens.

Arms and Interventions

Arm Intervention/Treatment
Experimental: SynergEyes A2 Hybrid Contact Lens

Device: SynergEyes A2 Hybrid Contact Lens

  • Subject is using ocular medications for any reason or systemic medications which might interfere with contact lens wear

  • A known history of corneal hypoesthesia (reduced corneal sensitivity)
