Determining Ocular Dominance⁚ The 1.00D Blur Test
Accurately determining ocular dominance is vital for successful Biofinity Toric Multifocal fitting‚ as it influences lens power selection and ensures optimal visual performance. The 1.00D blur test is a reliable method for this assessment. Using the patient’s current spectacle prescription‚ temporarily introduce a +1.00 diopter lens over one eye. Ask the patient to identify which eye is more comfortable and provides clearer vision. The eye with less blur is typically the dominant eye. Repeat the procedure for the other eye. This test helps identify the eye that will receive the primary distance correction in the multifocal lens. The non-dominant eye receives the secondary correction‚ which is typically designed to support near vision. While the 1.00D blur test provides a valuable starting point‚ consider patient feedback and visual acuity measurements to refine the determination. In cases of ambiguity or conflicting results‚ alternative methods or further testing may be necessary to confirm ocular dominance before proceeding with lens selection. Accurate dominance assessment is crucial for maximizing patient satisfaction.
Lens Selection⁚ Considering Power‚ Add Power‚ and Design (D vs. N)
Biofinity Toric Multifocal lenses offer a wide range of parameters to cater to individual patient needs. Careful consideration of power‚ add power‚ and lens design (D vs. N) is crucial for optimal fitting. Start by determining the appropriate spherical power based on the patient’s refractive error. Add power selection depends on the patient’s near vision needs and presbyopia level. CooperVision’s Biofinity Toric Multifocals provide multiple add power options‚ allowing for fine-tuning to achieve optimal near vision. The choice between “D” (dominant) and “N” (non-dominant) designs impacts the distribution of visual correction between distance and near vision. The “D” lens prioritizes distance vision in the dominant eye‚ while the “N” lens emphasizes near vision in the non-dominant eye. Patient lifestyle and visual demands should guide the design choice; those needing superior distance vision might benefit from the “D” design‚ while those prioritizing near tasks might prefer the “N” design. Remember that the selection process often involves trial and error‚ with adjustments made based on patient feedback and visual acuity assessments. Consider using a fitting calculator for guidance‚ but always prioritize individual patient needs.
