Multifocal Biweekly Contact Lenses
Simultaneous Vision and Modality Rationale
Aspheric or concentric optics provide distance, intermediate, and near vision while a fourteen day cycle reduces deposit induced contrast loss. The modality balances adaptation ease, hygiene, and per day cost for early to moderate presbyopes.
Patient Selection and Advantages
- Early to moderate presbyopes: Higher success before large adds are needed
- Frequent replacement: Limits deposit impact on near zone clarity
- Moisture retention materials: Surface tech preserves comfort during prolonged near work
- Upgrade path from monovision: Better binocularity and depth perception
- Compliance capable: Patients who can track a two week discard and value improved hygiene
