Step 1: Initial Lens Selection and Over-Refraction
Initially, select a diagnostic lens based on the patient’s refraction. Over-refraction is crucial; typically, plus 0.50 to 1.00 D is added to the distance prescription. This compensates for the expected minus drift often experienced with multifocal contact lenses.
Evaluate binocular vision and subjective responses carefully. Remember, the goal is to establish a starting point for fine-tuning, not a final prescription. Consider patient history and lifestyle during this initial assessment.
Step 2: Refinement and Optimization
Following the initial fitting, refine the prescription based on patient feedback. Adjust the add power in 0.25D increments, prioritizing comfortable near vision without compromising distance clarity. Monitor for symptoms like glare or halos, indicating potential over-correction.
Evaluate lens stability and rotation. Consider a slight adjustment to the base curve or diameter if needed. Patient comfort is paramount; address any dryness or irritation promptly to ensure long-term success.
Determining Add Power
Add power selection is crucial; low adds (+0.75 to +1.50) are common, while higher adds (+2.75 to +3.50) require careful consideration and refinement.
Low Add Powers (+0.75 to +1.50)
For low add powers, initiate the fitting with the patient’s current distance Rx, adding +0.75 to +1.50. Over-refraction is key; a slight plus refinement often improves near acuity. Consider a monovision assessment if initial multifocal attempts prove challenging. Patient feedback regarding clarity at all distances is vital for successful adaptation, ensuring comfortable vision.
Intermediate Add Powers (+1.75 to +2.50)
With intermediate adds, begin the fitting process utilizing the patient’s existing distance prescription, incorporating an add power between +1.75 and +2.50. Careful over-refraction is crucial, often requiring a slight plus or minus adjustment. Monitor for potential glare or halos, and assess binocularity thoroughly to optimize visual performance and patient comfort.
High Add Powers (+2.75 to +3.50)
For high add powers, a more conservative approach to over-refraction is generally recommended. Start with the prescribed distance power and add, then adjust in small increments. Pay close attention to distance acuity, as higher adds can sometimes compromise it. Ensure adequate illumination during assessment, and consider a trial frame evaluation if needed.
Distance Power Selection
Begin with the patient’s existing spectacle prescription, utilizing trial lens sets for precise refinement and diagnostic fitting to optimize visual clarity.
Considering Existing Spectacle Prescription
Start by thoroughly reviewing the patient’s current spectacle prescription, noting any recent changes or complaints regarding their vision correction. Utilize this information as a foundational starting point for the contact lens fitting process. However, remember that spectacle refraction and contact lens refraction are not identical; adjustments are almost always necessary. Carefully assess the patient’s visual needs and lifestyle to determine if a slight modification to the spectacle prescription is warranted when initiating the trial lens fitting.
Trial Lens Sets and Diagnostic Fitting
Employ diagnostic sets containing a range of Air Optix Multifocal parameters, including varying add powers and base curves, to facilitate an efficient fitting.
