Simplified Fitting Philosophy

The fitting process for Biofinity Multifocal Toric lenses has been streamlined to make it easier and more efficient for eye care professionals. This simplified approach leverages real-world experiences and focuses on key principles to ensure a successful fitting outcome. The process begins with a thorough understanding of the patient’s needs and visual requirements. This includes a comprehensive eye exam, determining ocular dominance, and selecting the appropriate lens design (D or N) based on the patient’s presbyopic needs. The fitting guide emphasizes the use of the OptiExpert app, which provides a valuable tool for calculating the correct lens power and axis. The app simplifies the selection process, making it more precise and efficient. The simplified fitting philosophy also encourages eye care professionals to select the initial trial lens based on the patient’s spectacle refraction and add power. By using this approach, the fitting process becomes more intuitive and predictable, allowing for a smoother transition from spectacle correction to contact lens wear. The emphasis on patient comfort and clear vision throughout the day ensures a positive experience for both the patient and the practitioner.

Initial Visit

The initial visit sets the foundation for a successful Biofinity Multifocal Toric fitting. It involves a comprehensive assessment of the patient’s visual needs and ocular health. The eye care professional should begin with an up-to-date spectacle refraction, including the add power. This provides a starting point for determining the patient’s distance and near vision requirements. A crucial step is identifying ocular dominance, which helps in selecting the appropriate lens design for each eye. Using the OptiExpert app to establish the initial trial lens order is highly recommended. The app simplifies the process by calculating the correct lens power and axis based on the patient’s spectacle refraction. During the initial visit, it’s important to discuss the patient’s expectations for contact lens wear, including their lifestyle, activities, and any previous experiences with contact lenses. Open communication ensures that the chosen lens design and parameters meet the patient’s specific needs and preferences. This thorough initial evaluation sets the stage for a smooth fitting process and helps ensure patient satisfaction with the Biofinity Multifocal Toric lenses.

Trial Fit

The trial fit is a critical stage in the Biofinity Multifocal Toric fitting process, where the chosen lens parameters are put to the test. First, the eye care professional should select the trial lens axis closest to the spectacle axis. Biofinity Toric lenses offer round-the-clock axes in 10-degree steps, ensuring precise alignment with the patient’s corneal astigmatism. Once the lens is selected, it’s inserted into the patient’s eye and allowed to settle for 10 minutes. This allows the lens to conform to the corneal shape and minimize any initial discomfort. During this settling period, the eye care professional can observe the lens fit and assess its stability on the eye; After the 10-minute settling time, the eye care professional should evaluate the contact lens fitting, paying close attention to lens movement, centration, and any signs of discomfort. Visual acuity is then assessed both at distance and near, with the patient wearing the trial lens. This provides valuable information about the lens’s ability to provide clear vision at different distances. If the initial trial lens doesn’t provide satisfactory vision or comfort, adjustments to the lens parameters, such as sphere power, add power, or axis, can be made. The trial fit is an iterative process that allows the eye care professional to fine-tune the lens parameters until optimal vision and comfort are achieved.

Follow-Up Visit

The follow-up visit is essential for ensuring the long-term success of Biofinity Multifocal Toric lens wear. During this appointment, the eye care professional assesses the patient’s adaptation to the lenses and addresses any concerns or issues that may have arisen. First, the eye care professional will evaluate the patient’s visual acuity at distance and near, ensuring optimal vision in all conditions. This assessment helps determine if any further adjustments to the lens parameters are necessary. Next, the eye care professional will assess the patient’s comfort and tolerance to the lenses. They’ll inquire about any signs of dryness, irritation, or discomfort, paying attention to the patient’s overall experience with the lenses. The eye care professional will also check for any signs of lens-related complications, such as corneal edema or infection. This ensures the lenses are not causing any adverse effects on the eye’s health. If the patient reports any discomfort or vision issues, the eye care professional can make necessary adjustments to the lens parameters or recommend alternative solutions. The follow-up visit also provides an opportunity for the eye care professional to educate the patient on proper lens care and hygiene practices. This includes demonstrating proper insertion and removal techniques, emphasizing the importance of cleaning and disinfecting the lenses, and discussing the recommended wearing schedule. The aim of the follow-up visit is to ensure that the patient is experiencing optimal vision, comfort, and lens health, fostering a positive and long-lasting lens-wearing experience.

Clinical Tips

Successful Biofinity Multifocal Toric lens fitting goes beyond following a strict guide. Here are some clinical tips to enhance the fitting experience and ensure optimal patient satisfaction⁚ For patients with high refractive errors, consider starting with a lower ADD power. This approach allows for gradual adaptation to multifocal correction and helps minimize initial discomfort or confusion. When evaluating visual acuity, encourage patients to read a small print chart, like a Snellen near vision chart. This helps assess their ability to comfortably read at close distances. For patients who experience dryness or irritation, explore the benefits of using lubricating drops or artificial tears. These products can enhance lens comfort and minimize dryness-related discomfort. Consider using a lensometer to verify the lens power and axis, especially when dealing with high cylinder values. This ensures the lens is correctly oriented and provides the intended correction; If the patient reports difficulty inserting or removing the lenses, provide hands-on guidance and demonstrations. Proper handling techniques are crucial for preventing lens damage or discomfort. For patients with significant astigmatism, consider using a slit lamp to assess the lens fit and ensure the lens is properly centered on the cornea. This visual inspection helps prevent rotational instability or lens decentration. These clinical tips, combined with the fitting guide, empower eye care professionals to achieve optimal outcomes for their patients, ensuring a successful and comfortable Biofinity Multifocal Toric lens-wearing experience.

Optimised Toric Lens Geometry

Biofinity Multifocal Toric lenses feature a meticulously engineered toric lens geometry designed to provide stable and comfortable wear for patients with astigmatism. This optimized geometry ensures the lens remains securely in place on the eye, delivering consistent vision correction and minimizing lens rotation. The advanced toric design incorporates a specific base curve and cylinder power to match the unique curvature of the cornea, effectively addressing the refractive errors associated with astigmatism. The lens’s optimized geometry is further enhanced by its round lens edge, which promotes smooth movement and reduces the potential for irritation or discomfort. This carefully crafted design contributes to the lens’s exceptional comfort and stability, allowing patients to experience clear and consistent vision throughout the day. Biofinity Multifocal Toric lenses offer a reliable solution for patients with astigmatism and presbyopia, providing them with the freedom to enjoy sharp, clear vision at all distances.

Balanced Progressive Technology

Biofinity Multifocal Toric lenses utilize Balanced Progressive Technology to deliver seamless vision correction for both distance and near vision. This innovative technology seamlessly blends multiple focal powers within a single lens, eliminating the need for multiple pairs of glasses. The lens incorporates a progressive design with a gradual transition between the distance and near zones, allowing for smooth and effortless focus shifts. The balanced progressive design ensures that both near and distance vision are optimally corrected, providing clear and comfortable vision for all activities. The technology allows patients to easily switch between reading, computer use, and distance vision without the need for constant lens adjustments.
