Pre-Fitting Considerations

Evaluate the patient’s lifestyle, visual demands, and ocular health to ensure suitability for Biofinity Multifocal lenses. Assessing expectations and adapting to individual needs is crucial for success.

Determining Eye Dominance

Determining eye dominance is a critical step in fitting Biofinity Multifocal lenses. The dominant eye, typically the one preferred for distance tasks, influences how the lenses are prescribed. Use the fogging technique: blur the patient’s vision with plus lenses and gradually increase the power until discomfort occurs. The eye most bothered by the blur is usually dominant. Alternatively, the 1.50 blur test can be used, where the patient identifies which eye struggles more with blur. Accurate determination ensures proper lens orientation and power allocation, optimizing near, intermediate, and distance vision. This step is vital for achieving balanced binocular vision and patient satisfaction with multifocal lenses.

Assessing Patient Needs and Lifestyle

Assessing patient needs and lifestyle is essential for successful Biofinity Multifocal lens fitting. Consider the patient’s daily activities, such as reading, driving, or using digital devices, to understand their visual demands. Determine if they prioritize near, intermediate, or distance vision based on their lifestyle. For example, active individuals may benefit from lenses optimized for distance, while those who work on computers may prefer intermediate focus. Additionally, discuss their preferences, such as whether they wear glasses or prefer contact lenses full-time. This comprehensive evaluation ensures the lenses align with their lifestyle, enhancing comfort and satisfaction. By tailoring the fitting to their unique needs, you can optimize visual performance and patient adaptation to multifocal lenses.

The Fitting Process

The Biofinity Multifocal fitting process begins with lens selection based on refraction and eye dominance. Assess lens fit, orientation, and comfort to ensure optimal visual performance and patient satisfaction.

Step 1: Initial Lens Selection Based on Refraction

Initial lens selection begins with a precise refraction to determine the spherical equivalent for distance power, corrected for vertex distance. Dominance is assessed using the fogging technique, ensuring the dominant eye is prioritized for distance vision. The spherical equivalent calculation guides the selection of the base distance power for each eye. Add powers are then chosen based on the patient’s near vision requirements. Lenses are selected to match the patient’s refractive needs, ensuring optimal visual balance. If significant refractive differences exist between eyes, monocular over-refraction may be necessary to fine-tune the prescription. This step is crucial for achieving accurate lens fitting and ensuring patient satisfaction with multifocal performance.

Step 2: Assessing Lens Fit and Orientation

After initial lens selection, the next step involves assessing the lens fit and orientation. Allow the trial lenses to settle on the eyes for approximately 15 minutes to ensure proper adaptation. Treat the lens as a toric initially, evaluating its orientation and overall fit. Check the visual acuity at distance, intermediate, and near to ensure optimal performance. Assess comfort and centration, making adjustments as needed. If vision is unacceptable, consider re-evaluating the power or consulting the fitting guide for further refinement. Proper fit and orientation are critical for achieving clear vision and patient satisfaction with Biofinity Multifocal lenses.

Evaluating Visual Performance

Evaluating visual performance involves assessing clarity at near, intermediate, and distance ranges. Ensure binocular balance for optimal functionality and patient satisfaction with these lenses.

Checking Near and Intermediate Vision

Evaluating near and intermediate vision is crucial for ensuring proper lens functionality. Begin by assessing clarity at various distances, starting with near vision tasks like reading. Use trial lenses or the fogging technique to determine the optimal add power for each eye. Intermediate vision, such as viewing objects at arm’s length, should also be tested to ensure seamless transitions between focal points. Proper orientation of the multifocal design is key to achieving clear vision at all ranges. Allow the lenses to settle for 15 minutes before evaluation to ensure accurate results. Patient feedback is essential; ask about comfort and sharpness at different distances to fine-tune the fit and address any discrepancies.

Ensuring Binocular Vision Balance

Binocular vision balance is essential for comfortable and effective vision with Biofinity Multifocal lenses. After fitting, assess how the lenses perform together by evaluating distance vision with both eyes open. Use tools like CooperVision’s OptiExpert app to guide the fitting process and ensure proper alignment. The fogging technique can help determine eye dominance, ensuring the correct lens power is assigned to each eye. Test intermediate and near vision tasks to confirm clarity and comfort. If binocular vision is unbalanced, consider adjusting the add power or lens orientation. Allow the lenses to settle for 15 minutes before final assessment, as adaptation time may influence results. Patient feedback is critical; address any discrepancies to achieve optimal visual harmony and ensure a successful fitting experience.

Troubleshooting Common Fitting Issues

Identify issues like discomfort or blurry vision, then adjust lens power or orientation. Use monocular refraction to refine prescriptions and ensure proper fit for optimal visual clarity and comfort.

Addressing Discomfort or Vision Discrepancies

When patients experience discomfort or vision discrepancies with Biofinity Multifocal lenses, it’s essential to reassess the fit and prescription. Start by evaluating lens orientation and ensuring proper centration. Check for power discrepancies between eyes, as this can cause binocular vision imbalance. If discomfort persists, consider the lens material or wearing schedule; For vision issues, perform a monocular refraction to refine the prescription, focusing on the eye with the most significant blur. Adjust the near or intermediate add powers based on patient feedback. Ensure the lenses are clean and well-maintained, as debris can exacerbate discomfort. If issues remain, consult the Biofinity Multifocal fitting guide for advanced troubleshooting tips or consider alternative lens options.

Follow-Up and Aftercare

Schedule regular follow-up appointments to monitor lens performance and patient adaptation. Ensure proper lens care and hygiene practices are followed for optimal comfort and vision clarity.

Scheduling Follow-Up Appointments

Regular follow-up appointments are crucial to ensure optimal adaptation to Biofinity Multifocal lenses; Schedule the first follow-up within one week to assess initial comfort and vision clarity. A second appointment after two weeks helps confirm lens performance and address any discomfort. Annual check-ups are recommended to monitor eye health and lens fit. During these visits, evaluate near, intermediate, and distance vision to ensure the lenses meet the patient’s needs. Use tools like CooperVision’s OptiExpert app for precise fitting and adjustments. Proper follow-up ensures long-term satisfaction and prevents potential issues, reinforcing the importance of consistent aftercare for presbyopic patients using Biofinity Multifocal lenses.

Providing Patient Care and Maintenance Tips

Proper care and maintenance are essential for the longevity and comfort of Biofinity Multifocal lenses. Patients should be advised to clean and store lenses using a multipurpose cleaning solution, avoiding tap water. Emphasize the importance of replacing lenses as prescribed and not exceeding the recommended wear time. Teach patients to handle lenses with clean, dry hands and avoid touching the lens surface to minimize contamination. Recommend regular follow-ups to monitor lens fit and eye health. Additionally, educate patients on proper insertion and removal techniques to prevent discomfort or damage. By following these care tips, patients can enjoy clear vision and optimal comfort with their Biofinity Multifocal lenses, ensuring a positive experience and maintaining eye health.
