A quantitative and qualitative assessment of the NOVAWET-Perception bifocal contact lens.
OBJECTIVE
We prospectively evaluated the NOVAWET-Perception multifocal contact lens for comfort and performance.


METHODS
We fit 28 presbyopic patients with this multifocal contact lens. This multifocal rigid gas permeable lens has a multiaspheric back surface and multiple eccentricity values, allowing for a natural field of vision at all angles. Patients were evaluated prior to inclusion in the study and then at 1,3, and 9 months. Evaluations included slit lamp examination, visual acuity, contrast sensitivity, and completion of a questionnaire regarding comfort and overall satisfaction.


RESULTS
At the end of the study, 14 of 28 patients (50%) were successfully wearing the NOVAWET-Perception lenses. Of these, 12 (86%) achieved J2 or better near vision and 13 (93%) achieved 20/25 or better distance vision. Fourteen patients failed to complete the study.


CONCLUSIONS
We believe the NOVALENS multifocal contact lens is a viable option for the correction of many presbyopic patients.
