It’s important to note that the fitting process may vary depending on the individual patient’s needs and the eye care professional’s approach. Regular follow-up appointments are crucial to ensure that the lenses continue to fit comfortably and provide clear vision.
Step 1⁚ Vertexing
Vertexing is a crucial step in fitting Dailies Total 1 Multifocal contact lenses. It involves measuring the distance between the corneal apex (the highest point of the cornea) and the front surface of the lens. This measurement, known as the vertex distance, is essential for determining the correct lens power to ensure optimal vision correction.
Here’s why vertexing is important⁚
- Accurate Lens Power⁚ The vertex distance influences the effective lens power. A longer vertex distance requires a slightly stronger lens power to compensate for the added distance between the lens and the cornea.
- Improved Visual Acuity⁚ Accurate vertexing helps ensure that the lens power is correctly aligned with the eye’s refractive error, resulting in sharper and clearer vision.
- Enhanced Lens Fit⁚ Vertexing helps determine the optimal lens base curve, ensuring a comfortable and stable fit on the eye.
During the vertexing process, the eye care professional will use specialized instruments to measure the vertex distance. They will then adjust the lens power accordingly to compensate for the measured distance. This ensures that the lenses are properly fitted and provide the best possible visual correction.
Step 2⁚ Determining the Lens Power
Once vertexing is complete, the next step is to determine the appropriate lens power for each eye. This involves considering the patient’s refractive error, which is the degree of nearsightedness, farsightedness, or astigmatism. The goal is to find the lens power that provides clear vision at both near and far distances.
For Dailies Total 1 Multifocal lenses, there are several lens power options available. These options include⁚
- Add Power⁚ The add power refers to the difference in lens power between the distance and near portions of the lens. A higher add power provides greater magnification for near vision.
- Distance Power⁚ This represents the lens power required to correct the patient’s distance vision.
- Near Power⁚ This power is determined by adding the distance power and the add power.
The eye care professional will use a variety of techniques to determine the best lens power combination for each patient. These techniques may include⁚
- Refraction⁚ A traditional eye exam that measures the eye’s refractive error.
- Trial Lens Fitting⁚ The patient tries on different lens power combinations to find the most comfortable and visually clear options.
