Total One Multifocal Fitting Guide: A Comprehensive Overview
Alcon’s TOTAL30 Multifocal, a monthly Water Gradient lens, offers brilliant vision at all distances, feeling remarkably comfortable even after 30 days of continuous wear.
Presbyopia, a natural age-related vision change, impacts near vision, often beginning around age 40. Multifocal contact lenses address this by providing clear vision at multiple distances – far, intermediate, and near.
TOTAL30 Multifocal lenses utilize Water Gradient Technology, mimicking the eye’s natural tear film for exceptional comfort. With a growing prevalence – expected to reach 1.37 billion by next year – effective multifocal fitting is crucial for eye care professionals.
Understanding the Total One Multifocal Lens Design
TOTAL30 Multifocal lenses are unique, being the first monthly Water Gradient multifocal design. This technology creates a lens with a high water content at the surface, maximizing comfort and oxygen permeability.
The lens provides excellent visual acuity across all distances, utilizing Alcon’s proven design. It aims to feel like “nothing” in the eye, even after a full 30 days of wear, addressing both vision and comfort needs.
Patient Selection for Total One Multifocal Lenses
Ideal candidates exhibit presbyopia and desire comfortable, high-quality vision correction at all distances with a monthly replacement schedule.
Identifying Suitable Candidates
Successful patients generally demonstrate moderate myopia and presbyopia, seeking a comfortable multifocal solution. Those experiencing dry eye often benefit from TOTAL30’s Water Gradient Technology. A thorough assessment of lifestyle and visual demands is crucial; active individuals and those requiring prolonged near or intermediate vision are excellent candidates. Prior contact lens wearers, even those previously dissatisfied, should be considered.
Comprehensive Eye Examination
A detailed exam includes refraction, assessing distance and near vision, plus a binocular vision evaluation. Keratometry and corneal topography map the cornea’s shape, vital for lens selection. Tear film assessment is essential, given presbyopes often experience dry eye. Rule out pathology; ensure ocular surface health supports contact lens wear. Pupil size measurements are also recommended.
Fitting Process: Initial Assessment
Initial steps involve a thorough refraction and visual needs analysis, alongside keratometry and corneal topography, to precisely understand the patient’s unique visual profile.
Refraction and Visual Needs Analysis
A detailed refraction is crucial, encompassing distance, intermediate, and near corrections, alongside a comprehensive lifestyle questionnaire. Understanding the patient’s daily activities – computer use, reading habits, driving – informs add power selection. Accurate assessment of visual demands ensures optimal lens performance, maximizing comfort and clarity at all distances. This analysis guides the initial trial lens choices, setting the stage for successful multifocal fitting.
Keratometry and Corneal Topography
Precise keratometry readings are essential for determining appropriate base curve selection with TOTAL ONE Multifocal lenses. Corneal topography provides a detailed map of the corneal surface, identifying irregularities or astigmatism that may impact lens fit and visual acuity. This data helps predict lens behavior and optimize comfort, ensuring stable and effective vision correction for presbyopic patients.
Trial Lens Selection and Fitting
Selecting the correct power and add for TOTAL ONE Multifocal lenses is crucial. Trial lenses allow for evaluating visual performance and comfort before final dispensing.
Choosing the Appropriate Power and Add
Determining the optimal power involves a thorough refraction, considering both distance and near corrections. The add power selection requires careful assessment of the patient’s near vision needs and lifestyle. Utilizing the ACUVUE Multifocal Fitting Calculator can significantly aid in this process, providing valuable recommendations based on individual patient data.
Trial Lens Insertion and Evaluation
Following proper insertion techniques is crucial for accurate evaluation. Assess visual acuity at distance, intermediate, and near, noting any fluctuations or complaints of haloes and glare. Patient feedback regarding comfort and clarity is paramount; encourage detailed descriptions of their visual experience throughout the trial period.
Subjective Refinement
Refine the prescription based on patient feedback, balancing distance, intermediate, and near vision. Prioritize comfort and minimize visual disturbances like haloes or glare.
Distance, Intermediate, and Near Vision Assessment
Evaluate vision at all distances using standardized charts. Assess distance acuity first, then intermediate (around 40cm, computer distance), and finally near (reading distance).
Inquire about clarity and comfort at each range.
Specifically, ask patients about any fluctuations or blurriness experienced during transitions between distances, noting any reported haloes or glare.
Patient Feedback and Adjustment
Actively solicit detailed feedback regarding visual performance in daily activities. Address any complaints of haloes, glare, or fluctuating vision promptly. Minor adjustments to lens power or add may be necessary to optimize comfort and clarity. Emphasize patience, as adaptation can take time, and open communication is crucial for success.
Addressing Common Fitting Challenges
Haloes and glare, or vision fluctuations, can occur; refine the fit with power adjustments and consider lens orientation. Patient education is key.
Haloes and Glare Management
Patients experiencing haloes or glare with TOTAL30 Multifocal lenses often benefit from a refinement of the lens power or a slight adjustment to the fitting parameters. Consider reducing the add power or altering the lens orientation within the eye. Thoroughly assess the patient’s visual complaints under various lighting conditions, and emphasize the importance of adaptation time, as these symptoms frequently diminish as the brain adjusts to the multifocal design.
Fluctuations in Vision
Occasional fluctuations in vision are common during the adaptation period with TOTAL30 Multifocal lenses. Reassure patients that this is often temporary, as the visual system learns to utilize different zones of the lens. Encourage consistent wear and avoid switching back to single-vision correction. Careful refraction and add power adjustments can also minimize these fluctuations.
Lens Care and Hygiene Instructions
Proper handling, cleaning, and disinfection are crucial for TOTAL30 Multifocal lenses to maintain comfort and prevent complications. Follow recommended protocols diligently.
Proper Handling Techniques

Store lenses in a clean case with fresh solution.
Cleaning and Disinfection Protocols
Routinely clean TOTAL30 Multifocal lenses with a multipurpose solution recommended by your eye doctor to remove debris and deposits; After cleaning, thoroughly rinse the lenses to eliminate residual solution. Disinfect lenses every time, even if not worn, using fresh solution. Never reuse solution, and always store lenses in a clean case.
Troubleshooting and Follow-Up
Address discomfort or redness promptly; schedule follow-up appointments to assess adaptation and vision quality. Regular check-ups ensure optimal lens fit and continued comfort.
Managing Discomfort and Redness
If patients experience discomfort or redness, immediate assessment is crucial. Rule out issues like overwear, improper lens handling, or solution sensitivities. Encourage artificial tear use and temporary lens removal. If symptoms persist, investigate corneal health and lens fit thoroughly. Discontinue wear if irritation continues, and refer if necessary, prioritizing patient well-being.
Scheduled Follow-Up Appointments
Consistent follow-up is vital for successful adaptation. Schedule initial checks one week post-fitting, then again at one and three months; Assess vision, comfort, and lens stability at each visit.
