What It Is
This device is a soft hydrophilic contact lens made from Hioxifilcon B, designed with a multi-aspheric multifocal structure. The lens provides vision correction for presbyopic patients by offering multiple focal points, allowing for clear vision at various distances. The hydrophilic nature of the lens ensures comfort and moisture retention, making it suitable for extended wear.
FDA-Cleared Indications
- Correction of presbyopia with a multifocal soft hydrophilic contact lens
- Correction of refractive errors requiring multifocal vision correction, as specified by the prescription and labeling
Clinical Applications
- Multifocal correction of near and distance vision in patients with presbyopia
- Prescription vision correction for patients who also have myopia or hyperopia
- Fitting by an optometrist or ophthalmologist after assessment of refraction, ocular health and lens fit
- Non-surgical correction of presbyopic vision in an outpatient eye-care setting
Practical Considerations
- The lens should be selected and fitted by a qualified eye-care professional using the patient's prescription, corneal measurements and ocular health assessment.
- Available parameters may include different powers, base curves and diameters; the exact range depends on the cleared lens configuration and manufacturer specifications.
- The patient's tear film, corneal surface and tolerance for soft contact lenses should be assessed before fitting.
- Patients should follow the prescribed wearing, cleaning, replacement and storage schedule. Wearing time should not be extended beyond the eye-care professional's instructions.
- Contact lenses are not generally considered an MRI hazard because they contain no substantial ferromagnetic material, but the lens should be managed according to the imaging facility's instructions. The lens may need removal for the examination or for accurate ocular assessment.
