When a prescriber determines no change in Rx for a previous wearer, what does this signify?

When a prescriber determines that there is no change in the prescription for a previous wearer, it indicates that the fitting process is complete. This conclusion suggests that the prescriber has evaluated the patient’s current vision and the effectiveness of their existing lenses. Since the prescription remains unchanged, it is understood that the previously fitted contact lenses are still appropriate for the patient's needs, demonstrating that they have successfully adapted to them and that the lens fit and vision correction are satisfactory.

This assessment reflects a comprehensive understanding of the patient's visual requirements and the effectiveness of the previously prescribed lenses. It signifies stability in the patient's ocular health and vision, leading the prescriber to conclude that the current regimen is both suitable and effective.

The other options do not accurately represent this situation: referring the patient to another prescriber would be more appropriate in cases requiring specialized care, while declaring lenses unsuitable is not relevant if there’s no change in prescription. Similarly, a patient choosing another option implies a change in selection rather than confirming the adequacy of the current prescription.
