Understanding their lifestyle, occupational needs, and specific visual complaints is crucial.
Specifically inquire about the duration and nature of their presbyopia symptoms, any prior multifocal contact lens experience (successes and failures), and their overall expectations. Assess their general health, ocular surface health, and tear film quality, as these factors significantly impact contact lens comfort and performance.
Document any existing ocular conditions, medications, and allergies. A comprehensive assessment lays the foundation for a successful Biofinity Multifocal fitting, ensuring patient satisfaction and optimal visual outcomes. This detailed approach minimizes potential fitting challenges later in the process.
Refraction and Add Power Determination
Accurate refraction is essential for Biofinity Multifocal success. Begin with a thorough cycloplegic refraction, especially for patients with accommodative spasm or fluctuating vision. Determine the best spectacle correction for distance and near, noting any residual astigmatism.
Add power determination requires careful consideration. Monocular add power refinement is recommended, starting with the patient’s habitual add or a +1.50D add if no history exists. Utilize a dynamic refraction technique, assessing near vision at various working distances to pinpoint the optimal add power.
Consider a binocular add power refinement to fine-tune the balance between distance and near vision. Document all refraction findings meticulously, as this data will guide initial trial lens selection and subsequent adjustments.
Slit Lamp Evaluation
A comprehensive slit lamp evaluation is crucial before fitting Biofinity Multifocal lenses. Assess the ocular surface for dryness, staining, and inflammation, as these conditions can impact lens comfort and performance. Evaluate lid structure and function, noting any abnormalities that might affect lens handling or centration.
Carefully examine the conjunctiva and cornea for any signs of pathology, such as pinguecula, pterygium, or irregularities. Pay close attention to tear film quality and quantity, as adequate lubrication is vital for multifocal lens success. Assess pupil size and shape in both photopic and scotopic conditions.
Document all findings thoroughly, as they will inform lens selection and management. Address any pre-existing ocular surface issues before proceeding with the fitting process to optimize patient comfort and visual outcomes.
Keratometry and Corneal Topography
Accurate keratometry and corneal topography are essential for successful Biofinity Multifocal fitting. Obtain reliable keratometry readings, both central and peripheral, to determine the base curve. Corneal topography provides a detailed map of the corneal surface, revealing any irregularities like astigmatism or corneal ectasia that could influence lens fit and visual performance.
Analyze topographic maps for corneal asymmetry, form factor, and overall corneal health. These measurements help predict lens centration and movement, crucial for multifocal lens function. Consider utilizing topography-guided fitting software if available, to optimize lens selection based on individual corneal characteristics.
Document all measurements meticulously, as they form the foundation for precise lens parameter selection and minimize potential fitting challenges.
Fitting Guide & Parameter Selection
Selecting appropriate base curves, diameters, and powers—including add powers—is vital for optimal vision and comfort with Biofinity Multifocal lenses.
Base Curve Selection
Base curve selection significantly impacts lens fit, comfort, and visual performance with Biofinity Multifocal lenses. A proper base curve ensures optimal corneal coverage and minimizes edge lift or pooling of tears. Generally, start with the patient’s current successful base curve if available, or utilize keratometry readings as a guide.
For new fits, consider a steeper base curve for steeper corneas and a flatter base curve for flatter corneas. CooperVision recommends evaluating the corneal topography to identify any irregularities that might influence base curve selection. Trial lenses with varying base curves are crucial for assessing the best fit. Observe lens movement and centration during the trial fitting to confirm adequate corneal coverage and avoid excessive movement, which can cause discomfort or blurred vision. Remember that individual corneal shapes vary, so empirical fitting isn’t always sufficient.
Diameter Selection
Diameter selection is critical for Biofinity Multifocal lens centration and overall comfort. An appropriately sized diameter ensures the lens remains stable on the eye during blinks and gaze changes, preventing decentration that can compromise vision. Typically, a diameter of 14.0mm is a good starting point for many patients, but individual corneal diameters vary.
Consider the patient’s limbal ring size and palpebral fissure width when choosing a diameter. Larger diameters may be necessary for patients with larger corneas or wider palpebral fissures, while smaller diameters might be suitable for those with smaller corneas. Observe lens centration carefully during the trial fitting; the lens should be well-centered with minimal decentration in all directions of gaze. If decentration occurs, adjust the diameter accordingly – larger for superior decentration, smaller for inferior decentration.

Encourage them to report any visual disturbances, discomfort, or adaptation issues. Thorough follow-up is crucial to gather feedback and make necessary adjustments, maximizing the success of the fitting.
Refinement and Evaluation
Refinement involves subjective refraction over trial lenses, assessing visual acuity at all distances, and evaluating lens comfort to address fitting challenges effectively.
Subjective Refraction Over Trial Lenses
Subjective refraction is a crucial step during the Biofinity Multifocal fitting process, performed over the trial lenses to fine-tune the prescription for optimal vision. Begin by confirming the initial refraction and then systematically refine both distance and near corrections. Utilize a standard refraction flow, asking the patient to compare views with and without added power, focusing on clarity and comfort.
Pay close attention to the patient’s responses, particularly regarding any halos, glare, or distortions. Small adjustments to the add power can significantly impact visual performance. Consider performing monocular refraction to isolate any issues with one eye. Document all changes made during the subjective refraction, noting the patient’s subjective preferences and any observed visual phenomena. This detailed record will be invaluable for subsequent adjustments and long-term management.
Assessment of Visual Acuity at Distance and Near
Following subjective refraction, a thorough assessment of visual acuity is essential, evaluating performance both at distance and near. Distance acuity should be measured with and without the trial lenses, using a standard eye chart. Near acuity testing should be conducted at the patient’s typical reading distance, utilizing appropriate near vision charts or reading material.
Compare the acuity achieved with the trial lenses to the patient’s pre-lens vision. Significant improvements indicate a successful fit. Assess intermediate vision as well, as this is often a challenge for multifocal lens wearers. Document all acuity measurements clearly, noting any discrepancies between eyes. This data, combined with the patient’s subjective responses, will guide further refinements to the prescription and lens parameters.
Evaluation of Lens Comfort and Fit
Beyond visual performance, assessing lens comfort and fit is paramount for successful Biofinity Multifocal adaptation.
