Understanding Biofinity Multifocal Contact Lenses

Biofinity Multifocal contact lenses, manufactured by CooperVision, are a popular choice for presbyopic patients seeking clear vision at all distances. Their silicone hydrogel material provides high oxygen transmissibility, contributing to comfortable wear. This guide will walk you through the process of successfully fitting these lenses.

Patient Selection: Identifying Ideal Candidates

Choosing the right patient is crucial for successful Biofinity Multifocal fitting. Consider these factors:

Age and Presbyopia Progression: Patients typically begin experiencing presbyopia in their mid-40s. The severity of presbyopia impacts lens selection.
Refractive Error: Biofinity Multifocals accommodate a range of refractive errors, but severe myopia or hyperopia may require alternative solutions.
Pupil Size: Larger pupils can affect the performance of multifocal lenses, potentially leading to visual disturbances.
Lifestyle and Visual Demands: Patients with demanding visual needs (e.g., frequent near-work) might benefit more from this lens type than those with less demanding lifestyles.
Adaptation Abilities: Some patients adapt more easily to multifocal lenses than others. A thorough discussion of expectations is crucial.

Key Lens Parameters and Their Impact

Understanding the lens parameters is vital for accurate fitting. Biofinity Multifocals come in various parameters:

Power (Sphere, Cylinder, Axis): Correcting refractive errors is fundamental. Accurate measurements are non-negotiable.
Add Power: This parameter compensates for presbyopia, increasing the power for near vision. The appropriate add power depends on the patient's near visual acuity needs.
Diameter: The lens diameter influences comfort and how well the lens centers on the eye. Proper diameter is critical for optimal vision.
Base Curve: This refers to the curvature of the back surface of the lens. The base curve must match the curvature of the cornea for proper fit and comfort.

A detailed discussion of these parameters with the patient is necessary.

Fitting Strategies: A Step-by-Step Approach

A successful Biofinity Multifocal fitting involves a systematic approach:

Initial Assessment: This includes a comprehensive eye examination, determining the patient's refractive error, and assessing the severity of their presbyopia.
Lens Selection: Choose the appropriate lens parameters based on the initial assessment. Consider starting with a lower add power and gradually increasing if needed.
Trial Lens Fitting: Begin by fitting a trial pair of Biofinity Multifocals to determine the optimal power and fit. Observe the lens centration and movement on the eye.
Visual Acuity Assessment: Assess distance, intermediate, and near visual acuity with the trial lenses. Adjust parameters as necessary to achieve the best vision at all distances.
Patient Feedback: Gather feedback from the patient regarding comfort, visual clarity, and overall satisfaction. Addressing concerns is a crucial step in the process.
Follow-up Appointments: Schedule regular follow-up appointments to monitor lens adaptation, assess visual acuity, and make any needed adjustments.

Patient education throughout this process is key.

Troubleshooting Common Issues

Even with careful fitting, some issues may arise:

Blurred Vision: This could indicate incorrect power, poor lens centration, or an inappropriate add power. Re-evaluate the lens parameters.
Discomfort: Dry eyes, lens displacement, or an ill-fitting lens could cause discomfort. Investigate the cause to adjust accordingly.
Halos or Glare: These issues may occur at night or in low light conditions. Reducing the add power may mitigate this.
Adaptation Difficulties: Some patients may struggle to adapt to multifocals. Provide reassurance and address their concerns. Patient education is crucial here.

Remember, patience and thorough communication are key.

Advanced Considerations: Managing Specific Patient Needs

Certain patient demographics might require additional consideration:

High Myopia/Hyperopia: Special fitting techniques may be needed for patients with high refractive errors. Consider consulting with a specialist.
Keratoconus: Biofinity Multifocals might not be suitable for all patients with keratoconus. Explore alternative lens options.
Aphakia/Pseudophakia: Specific fitting considerations apply to these conditions. CooperVision offers resources on this.

Always prioritize the best solution for each individual patient.

Conclusion: Mastering Biofinity Multifocal Fitting

Successful Biofinity Multifocal fitting relies on a thorough understanding of lens parameters, patient selection, and effective fitting strategies. By following this guide and prioritizing patient communication, you can enhance patient satisfaction and achieve optimal visual outcomes. Remember to consult CooperVision's resources for the latest fitting recommendations and best practices. Mastering this fitting process will improve your practice and the lives of your patients who struggle with presbyopia.
