This material ensures long-lasting comfort and reduces the risk of dryness. The extensive parameter range makes Biofinity Multifocal lenses versatile for patients with different visual requirements. Proper alignment and movement are critical for optimal performance, making precise fitting essential. These features collectively provide a tailored solution for presbyopic patients seeking clear, comfortable vision at all distances.
The Fitting Process: Step-by-Step Guide
Biofinity Multifocal fitting involves assessing visual acuity, performing over-refraction, and using trial lenses for precise power determination. Optimize with handheld lenses to ensure clear near, intermediate, and distance vision for presbyopic patients.
4.1. Initial Assessment and Visual Acuity
The initial assessment for fitting Biofinity Multifocal contact lenses begins with evaluating the patient’s binocular and monocular visual acuity. This step helps determine the baseline vision and identifies any discrepancies between the two eyes. Assess near vision with the room lights on to simulate real-world conditions, ensuring clarity at various distances. Use a standard reading chart to measure near visual acuity, focusing on the patient’s ability to read small print comfortably. Over-refraction is also performed to refine the prescription further, ensuring the lens power matches the patient’s needs. Proper illumination is crucial during this process to avoid inaccuracies. This step-by-step evaluation ensures a personalized fit, addressing presbyopia effectively while maintaining optical clarity. The goal is to optimize vision at all distances, providing a seamless transition between near, intermediate, and far vision. This initial assessment lays the foundation for a successful fitting process.
4.2. Over-Refraction and Lens Power Determination
Over-refraction is a critical step in determining the correct lens power for Biofinity Multifocal contact lenses. This process involves refining the patient’s prescription to ensure optimal vision at all distances. Using handheld trial lenses or a flipper, the practitioner assesses the patient’s visual acuity and makes precise adjustments. It is important to avoid using a phoropter, as it may not provide accurate results for multifocal lenses. The patient should keep both eyes open during this process to ensure natural vision conditions. The lens power is determined based on the patient’s refractive error, presbyopic needs, and lifestyle requirements. Proper over-refraction ensures that the selected lens powers align with the patient’s visual demands, minimizing adaptation time. Accurate lens power determination is essential for achieving clear near, intermediate, and distance vision, making this step pivotal in the fitting process. By carefully refining the prescription, practitioners can optimize the performance of Biofinity Multifocal lenses for their patients.
4.3. Trial Lens Fitting and Optimization
Trial lens fitting is a crucial step in ensuring the optimal performance of Biofinity Multifocal contact lenses. After determining the appropriate lens powers through over-refraction, the practitioner fits the patient with trial lenses to assess comfort and vision. The patient should wear the lenses for a short period to evaluate clarity at near, intermediate, and distance vision. During this process, the practitioner observes how the lenses interact with the eyes, checking for proper centration and movement. Any discomfort or visual disturbances are addressed by adjusting the lens parameters or power. Optimization may involve fine-tuning the add power or cylinder axis for astigmatism, ensuring the lenses meet the patient’s specific needs. The goal is to achieve a balance between visual acuity and comfort, allowing the patient to adapt seamlessly to the multifocal design; Effective trial lens fitting and optimization ensure a successful wearing experience, making Biofinity Multifocal lenses a reliable choice for presbyopic individuals seeking clear and comfortable vision correction.
Follow-Up Care and Maintenance
Regular follow-up appointments are essential to monitor lens performance and eye health. Proper cleaning and maintenance of Biofinity Multifocal lenses ensure longevity and comfort. Use compatible cleaning solutions to preserve lens material properties and maintain clear vision.
5.1. Post-Fitting Evaluation and Adjustments
Following the initial fitting, a post-fitting evaluation is crucial to ensure optimal performance of Biofinity Multifocal lenses. Assess both near and distance visual acuity to confirm clarity and comfort. Check for any signs of discomfort or irritation, such as redness or dryness, which may indicate a need for adjustments. Evaluate the lens fit on the eye to ensure proper centration and movement. If necessary, refine the lens parameters, such as power or base curve, to improve vision or comfort. Patient feedback is key; address any concerns or difficulties they may be experiencing. Regular follow-ups help maintain eye health and ensure the lenses continue to meet the patient’s needs over time. Proper adjustments can enhance the overall wearing experience, ensuring satisfaction and longevity of lens use;
5.2. Proper Lens Care and Hygiene
Proper lens care and hygiene are essential for maintaining the health of your eyes and the longevity of Biofinity Multifocal lenses. Always wash your hands before handling the lenses to prevent contamination. Use a high-quality contact lens cleaning solution, such as Clear Care Plus with HydraGlyde or PureMoist, which is compatible with Biofinity’s Comfilcon A material. Gently rub the lenses with the solution to remove dirt and deposits, then rinse thoroughly. Store the lenses in fresh solution in a clean case, replacing the case every 3 months. Avoid using tap water, as it may contain harmful bacteria. Never share lens care products or cases, and replace lenses as prescribed to prevent microbial growth. Proper hygiene helps prevent irritation, infections, and discomfort, ensuring a safe and comfortable wearing experience.
