Understanding Biofinity Multifocal Lenses

Biofinity Multifocal contact lenses from CooperVision are popular multifocal lenses known for their high level of comfort and excellent vision correction. They utilize a unique material, silicone hydrogel, which allows for high oxygen permeability, crucial for healthy eyes. This guide provides a step-by-step approach to successfully fitting these lenses.

Key Features of Biofinity Multifocal

Silicone Hydrogel Material: Offers high oxygen transmissibility for comfortable, healthy wear.
Multifocal Design: Provides clear vision at various distances, eliminating the need for reading glasses.
Aquaform® Technology: Maintains moisture for all-day comfort.
Available in a range of powers and diameters: Ensures a precise fit for a wide range of patients.

Patient Selection for Biofinity Multifocal

Choosing the right patient is key to successful Biofinity Multifocal fitting. Consider these factors:

Ideal Candidates:

Presbyopic patients: Individuals experiencing age-related vision changes.
Patients seeking a comfortable, high-oxygen lens: Ideal for those who value comfort and eye health.
Patients with mild to moderate astigmatism: While not designed for high astigmatism, some patients may tolerate them.
Patients willing to adapt to a multifocal lens: Some adjustment period is normal.

Patients Less Suitable for Biofinity Multifocals:

Patients with significant astigmatism: Higher astigmatism often requires toric multifocal lenses.
Patients with significant ocular pathology: Conditions like dry eye disease may impact lens tolerance.
Patients with high expectations for immediate perfect vision: Adaptation time is necessary.

Step-by-Step Biofinity Multifocal Fitting Process

The fitting process requires a thorough approach, combining careful assessment with patient communication.

1. Initial Assessment and Patient History

Begin by taking a detailed patient history. This includes their visual needs, previous contact lens experience (if any), any eye conditions, and lifestyle factors. Perform a comprehensive eye exam to determine refractive error, pupil size, and corneal curvature.

2. Lens Selection and Trial Fitting

Based on the initial assessment, select an appropriate Biofinity Multifocal lens power and diameter. Always start with the patient's spherical equivalent power. Perform a trial fitting with one lens to assess comfort and initial visual acuity.

3. Evaluation of Visual Acuity and Comfort

Observe the patient's visual acuity at near, intermediate, and distance. Assess the lens comfort level and check for any signs of irritation or discomfort. Ask the patient about their subjective experience.

4. Refinement and Final Fitting

Based on the trial fitting results, adjust lens parameters as needed. This may involve changing the power, diameter, or addition. Continue with trial fittings until optimal visual acuity and comfort are achieved.

5. Dispensing and Follow-up Care

Once the optimal lens parameters are determined, dispense the lenses. Schedule a follow-up appointment to assess lens tolerance and visual acuity. Address any issues or concerns the patient may have.

Troubleshooting Common Biofinity Multifocal Issues

Even with careful fitting, some patients may encounter challenges. Here's how to address common problems:

Blurred Vision:

Possible causes: Incorrect power, poor lens centration, or inadequate adaptation.
Solutions: Re-evaluate refractive error, check lens fit and centration, provide adaptation instructions.

Discomfort or Dry Eyes:

Possible causes: Dry eye condition, inadequate lens fit, or material incompatibility.
Solutions: Assess for dry eye, consider different lens parameters, recommend artificial tears.

Halos or Glare:

Possible causes: Incorrect lens power, pupil size variation, or lens design incompatibility.
Solutions: Re-evaluate refractive error, consider alternative lens design or manufacturer.

Conclusion

Successfully fitting Biofinity Multifocal lenses requires a thorough understanding of the lens design, careful patient selection, and a systematic approach to the fitting process. By following this guide and paying close attention to patient feedback, you can help your patients achieve excellent visual outcomes and high levels of satisfaction with their new Biofinity Multifocal lenses. Remember to always refer to the manufacturer’s guidelines for detailed fitting instructions.
