Dailies Total One Multifocal Fitting Guide: A Comprehensive Overview
This guide details fitting Dailies Total One Multifocal lenses, addressing presbyopia’s rise and utilizing advanced technologies like SimVis Gekko for optimal vision correction.
Understanding Presbyopia and Multifocal Contact Lenses
Presbyopia, a natural age-related vision change, reduces the eye’s ability to focus on near objects. As the global population ages, the prevalence of presbyopia is increasing significantly, demanding effective solutions. Multifocal contact lenses address this by providing clear vision at multiple distances – near, intermediate, and far.
Dailies Total One Multifocal lenses utilize water gradient technology, mimicking the eye’s natural tear film for exceptional comfort. These lenses correct presbyopia, offering a seamless visual experience for patients seeking alternatives to glasses.
The Rise of Multifocal Contact Lens Demand
The demand for multifocal contact lenses is surging, driven by an aging global population and increasing presbyopia prevalence. By next year, the worldwide incidence is expected to rise substantially. Patients are actively seeking comfortable, convenient vision correction options beyond traditional spectacles.
Dailies Total One Multifocal lenses cater to this growing need, offering a daily disposable option with water gradient technology. This boosts practitioner confidence in fitting and provides excellent visual acuity across all distances.

The lens’s unique water gradient mimics the natural hydration of the cornea, promoting breathability and reducing end-of-day dryness, enhancing patient satisfaction and compliance.
Patient Selection Criteria
Successful multifocal lens fitting hinges on careful patient selection. Ideal candidates exhibit stable presbyopia, generally over 40, with moderate myopic or hyperopic refractive error. A comprehensive understanding of visual needs – near work, intermediate screen time, and distance vision – is crucial.
Practitioners must assess overall ocular health and patient motivation for contact lens wear to ensure optimal outcomes and minimize potential complications.
Identifying Suitable Candidates
Suitable candidates demonstrate consistent binocular vision and adequate tear film quality for comfortable lens wear. Moderate astigmatism is often manageable, but high levels may necessitate toric multifocal options. Patients actively seeking solutions for near and distance vision, tired of reading glasses, are prime candidates.
Lifestyle factors – extensive computer use, driving needs – significantly influence lens selection and add power determination, ensuring optimal visual performance.
Exclusion Criteria & Contraindications
Contraindications include unstable refractive error, significant ocular surface disease (severe dry eye), and active eye infections. Patients with certain systemic conditions, like uncontrolled diabetes, may be unsuitable due to impaired healing. Unrealistic expectations or poor compliance with lens care routines also warrant exclusion.
Careful consideration is needed for individuals with advanced glaucoma or macular degeneration, as multifocals may not address their specific visual needs effectively.
Initial Consultation & Refraction
A thorough patient history is crucial, detailing visual demands at all distances. Comprehensive refraction, including distance and near vision assessment, is essential. Monocular and binocular acuities must be recorded. Evaluate accommodative amplitude and pupil size.
Discuss lifestyle factors impacting vision, such as computer use and reading habits, to tailor the fitting approach. Accurate refraction forms the foundation for successful multifocal lens fitting.
Comprehensive Eye Examination
Perform a complete ocular health assessment, including evaluation of the cornea, conjunctiva, and anterior chamber. Assess tear film quality and quantity, as dryness can impact contact lens comfort. Measure corneal topography to rule out irregularities.
Evaluate binocular vision, including phoria and fusional ranges. Confirm the absence of pathology that could contraindicate contact lens wear. A healthy ocular surface is paramount for success.
Determining Add Power
Accurately ascertain the patient’s add power through subjective refraction, considering both distance and near corrections. Monocular add power determination is crucial, followed by binocular refinement. Utilize a near addition chart, and consider the patient’s visual demands.
Employ techniques like the minus build-up method to fine-tune the add power for optimal near vision. Over-refraction during diagnostic lens evaluation will further optimize the add.
Fitting Diagnostic Lenses
Select a range of diagnostic lenses encompassing various add powers and base curves to facilitate precise fitting. Begin with parameters closely matching the patient’s refraction and corneal curvature. Trial lens selection should prioritize comfort and initial visual acuity.
Employ over-refraction techniques to refine the add power and optimize visual performance at all distances. Careful assessment of lens centration and movement is vital for successful fitting.
Trial Lens Selection & Parameters
Initiate with a diagnostic set including +0.75D, +1;00D, +1.25D, and +1.50D add powers, alongside a range of base curves. Consider the patient’s spectacle add power as a starting point, adjusting based on lifestyle. Prioritize parameters that align with corneal topography.
Dailies Total One Multifocal offers a wide range, enabling tailored fitting. Document all parameters meticulously for consistent results and future reference.
Over-Refraction Techniques
Employ over-refraction to fine-tune visual acuity, particularly at near and intermediate distances. Start with +0.25D or +0.50D adjustments, observing the patient’s subjective response. Carefully balance distance and near vision, avoiding over-minusing or over-plussing.
