Understanding Presbyopia and Multifocal Correction

Presbyopia impacts near vision, necessitating multifocal correction. The Oasys Multifocal fitting guide aids in selecting lenses that restore clear vision at all distances.

The Science Behind Presbyopia

Presbyopia, a natural age-related process, reduces the eye’s ability to focus on nearby objects. The crystalline lens loses flexibility, diminishing accommodation. This impacts near tasks like reading. Understanding this physiological change is crucial when utilizing the Oasys Multifocal fitting guide. Successful fitting requires acknowledging the reduced focusing power and compensating with appropriate lens designs to restore comfortable near and distance vision, ensuring optimal visual acuity for patients.

How Multifocal Lenses Address Presbyopia

Multifocal lenses, guided by the Oasys Multifocal fitting guide, combat presbyopia by incorporating multiple power zones. These zones provide clear vision at varying distances – near, intermediate, and far. This design mimics the natural accommodation lost with age. Careful fitting, utilizing parameters from the guide, ensures seamless transitions and minimizes visual disturbances, offering a comfortable and comprehensive visual solution for presbyopic patients.

Key Parameters for Oasys Multifocal Fitting

The Oasys Multifocal fitting guide emphasizes base curve, diameter, and power – including add power – for precise vision correction and optimal comfort.

Base Curve (BC) Selection

Oasys Multifocal fitting requires careful base curve (BC) selection, influencing lens fit and visual acuity. The fitting guide suggests starting with the patient’s established BC, or a slightly steeper value if needed. Consider corneal topography; a steeper BC may improve near vision, while a flatter BC enhances distance clarity. Accurate BC selection minimizes aberrations and maximizes comfort, crucial for multifocal success.

Diameter (DIA) Considerations

Oasys Multifocal fitting demands precise diameter (DIA) assessment for optimal performance. The standard DIA is typically 14.5mm, but adjustments may be necessary. A larger DIA can improve stability, while a smaller one may enhance comfort. The fitting guide emphasizes observing lens centration and movement; decentration suggests DIA adjustments are needed for a stable, comfortable fit.

Power (PWR) Range and Add Power

The Oasys Multifocal range covers a broad spherical power spectrum, facilitating corrections for diverse prescriptions. Determining the appropriate add power is crucial for seamless near vision. The fitting guide recommends starting with the patient’s existing reading add, then refining based on subjective responses during trial lens wear, ensuring comfortable vision at all distances.

The Fitting Process: Step-by-Step Guide

A thorough patient assessment, precise refraction, and strategic trial lens selection—guided by the Oasys Multifocal fitting guide—are key to successful outcomes.

Initial Patient Assessment
