Initial Assessment and Ocular Dominance Determination
Before fitting Dailies Total 1 Multifocal lenses, a comprehensive initial assessment is essential. This involves reviewing the patient’s medical history, including any ocular conditions or previous contact lens experiences. Accurate refraction is critical to determine the appropriate lens power. Pay close attention to the patient’s subjective refraction and near addition.
Measuring pupillary distance (PD) and corneal diameter (HVID) provides valuable information for lens selection and fitting. Assess the tear film quality and quantity to identify potential dry eye issues that could impact lens comfort. Perform a slit-lamp examination to evaluate the overall health of the cornea, conjunctiva, and eyelids.
Determining ocular dominance is a crucial step in multifocal lens fitting. Utilize a reliable method, such as the +1.00D blur test, to identify the dominant eye accurately. This information helps guide the initial lens selection, often prioritizing the dominant eye with a specific power or lens design. Understanding ocular dominance is paramount for achieving balanced vision and minimizing visual disturbances.
A thorough initial assessment, combined with accurate ocular dominance determination, sets the foundation for a successful Dailies Total 1 Multifocal fitting experience.
Dailies Total 1 Multifocal Fitting Guide Chart and ADD Selection
The Dailies Total 1 Multifocal fitting guide chart is a valuable tool for streamlining the lens selection process. Consult the chart, considering the patient’s refractive error and add power, to determine the initial lens power for both eyes. The fitting guide simplifies initial lens choice, promoting efficiency in your practice.
Accurate ADD selection is paramount for optimizing near vision performance. Dailies Total 1 Multifocal lenses feature a 3 ADD SYSTEM, enabling personalized fitting for presbyopic patients. The fitting guide chart provides guidance on initial ADD selection based on the patient’s near addition. Remember to consider the patient’s visual needs and lifestyle when selecting the appropriate ADD power.
When selecting the ADD power, consider the lowest acceptable ADD to avoid over-minusing at distance. Over-minusing may induce asthenopia. If the patient reports difficulty with near vision after initial lens fitting, consider increasing the ADD power in 0.25D steps.
The Dailies Total 1 Multifocal fitting guide chart and careful ADD selection are essential for achieving optimal visual outcomes and patient satisfaction.
Step-by-Step Fitting Procedure
The Dailies Total 1 Multifocal fitting procedure involves a systematic approach to ensure optimal vision and comfort. First, obtain the patient’s recent subjective refraction. Then, use the fitting guide chart to select the initial lens power and ADD for each eye, prioritizing the dominant eye.
Next, insert the lenses and allow the patient to adapt for approximately 10-15 minutes. Assess distance and near visual acuity under normal viewing conditions. Evaluate lens centration and movement. Over-refract to refine the lens power, if necessary. With both eyes open, use hand-held lenses on each eye separately, by adding plus in 0.25D steps until the patient reports a decline in distance vision.
If distance vision is not satisfactory, consider adjusting the sphere power. If near vision is insufficient, increase the ADD power. Ensure the patient understands proper lens handling and care. Provide clear instructions on insertion, removal, and cleaning. Schedule a follow-up appointment to assess the patient’s adaptation and address any concerns.
This systematic approach to fitting Dailies Total 1 Multifocal lenses will lead to successful outcomes and happy patients.
Troubleshooting Common Fitting Issues
Even with a careful fitting procedure, some patients may experience issues with Dailies Total 1 Multifocal lenses. Common complaints include blurred vision at distance or near, halos, or discomfort.
If distance vision is blurry, refine the sphere power through over-refraction. Consider a slight power adjustment, typically in 0.25D steps. If near vision is inadequate, increase the ADD power, also in 0.25D increments. If halos are present, assess lens centration and movement. Poor centration can cause visual disturbances.
For discomfort, rule out dryness. Ensure the patient is using appropriate rewetting drops. If dryness persists, consider switching to a different lens material or modality. If lens movement is excessive, try a different base curve or diameter. If the patient still has issues, accurately determining ocular dominance is critical.
In some cases, monovision may be a better option. If the patient experiences persistent problems, refer them to a specialist. By addressing these common issues systematically, you can improve the fitting and ensure patient satisfaction with Dailies Total 1 Multifocal lenses.
