Calaview Etafilcon a Soft Hydrophilic Contact Lens for Daily Wear
Innova Vision
FDA Clearance Information
The Calaview etafilcon A contact lens was cleared by the FDA via the 510(k) pathway on November 29, 2007. It is manufactured by Innova Vision and classified as a Class 2 medical device.
What It Is
FDA-Cleared Indications
- Daily-wear vision correction in patients with refractive errors.
- Use as a soft hydrophilic contact lens when prescribed and fitted by an eye-care professional.
Clinical Applications
- Correction of nearsightedness or farsightedness during daily wear.
- Temporary vision correction without eyeglasses.
- Daily contact-lens wear following professional fitting and prescription.
- Replacement of an existing soft contact lens when the prescribed material and design are appropriate.
Reported off-label uses
- Bandage-lens use to protect the cornea after selected surface procedures or injuries.
- Therapeutic use for selected corneal epithelial disorders under ophthalmic supervision.
Off-label use: these uses are reported in practice or the literature but are not part of the FDA-cleared indications. Physicians may use a cleared device off-label based on their medical judgment; the manufacturer may not promote off-label uses.

Safety Profile
Evidence Limitations
Practical Considerations
- The lens must be fitted for the individual eye; parameters may include base curve, diameter and refractive power.
- It is intended for daily wear, not overnight or extended wear unless the specific labeling and eye-care professional expressly permit it.
- Wash and dry hands before handling, use only the recommended disinfecting or storage solution, and do not use water or saliva.
- Contact-lens wear is contraindicated or may require caution in active eye infection, significant ocular inflammation, severe dry eye or inability to follow lens-care instructions.
- A contact lens is not an implanted device and does not require MRI precautions; it should generally be removed before MRI according to the imaging facility's instructions.
