Step 1⁚ Initial Lens Selection

The initial lens selection for Dailies Total 1 Multifocal contact lenses is a crucial step in ensuring a successful fitting experience. This step involves carefully considering the patient’s individual needs and selecting the appropriate base curve, diameter, and ADD power for each eye.

The eye care professional will start by reviewing the patient’s most recent spectacle prescription, paying close attention to the spherical equivalent distance power, which is the average of the sphere and cylinder powers. This information provides a starting point for determining the initial lens power.

Next, the eye care professional will assess the patient’s ocular dominance, which refers to the eye that is primarily used for tasks requiring fine visual detail. A common method for determining ocular dominance is the “1.00D blur method,” which involves placing a +1.00 diopter lens over one eye and observing which eye the patient prefers to use for reading.

Based on the patient’s spectacle prescription, ocular dominance, and visual needs, the eye care professional will select the initial lens parameters, including the base curve, diameter, and ADD power. The ADD power, or “add,” refers to the additional power needed for near vision correction, and is typically available in low (LO), medium (MED), and high (HI) options.

Step 2⁚ Lens Optimization

Lens optimization is the process of fine-tuning the initial lens selection to achieve optimal visual acuity and comfort for the patient. This step involves a series of adjustments and evaluations, focusing on achieving the best possible vision at all distances.

The eye care professional will begin by assessing the patient’s vision at distance and near, using a variety of visual acuity tests. The patient will be asked to read charts at different distances, and the eye care professional will observe their ability to see clearly at both near and far.

Based on the initial vision assessment, the eye care professional may adjust the lens power, base curve, or diameter as needed. For example, if the patient experiences blur at near, the eye care professional may increase the ADD power or adjust the base curve to improve near vision.

Throughout the lens optimization process, the eye care professional will monitor the patient’s comfort and ensure that the lenses are well-tolerated. If the patient reports any discomfort or irritation, the eye care professional may adjust the lens parameters or suggest alternative lens options.
