2.7 Power Adjustment (Final Fit)
The RT-5100 is provided with the following two functions.
Auto adjustment function: The RT-5100 determines automatically the conditions such as LM data,
flexibility (patient’s age), refractive error type (myopia, hyperopia, astigmatism, oblique astigmatism,
anisometropia) and calculates the Final Fit value from the binocular full correction.
Semi-auto adjustment function: The operator can adjust the Final Fit value manually.
The Final Fit value calculated with the auto adjustment function (Final Fit) is lower than an average
prescription. It avoids overcorrecting the patient. Be sure to adjust the value with the semi-auto adjust-
ment function.
When the Final Fit value is obtained, be sure to check the patient’s viewability with a trial frame.
• The calculated Final Fit value is a guide for determining the final prescription. The final
prescription should be determined according to the patient’s acceptance.
• Be sure to measure and enter the full correction or LM data precisely. When the full
correction is inaccurate, the LM data is not entered regardless of patient’s wearing glasses,
or the entered data is not correct, the calculated value may not provide visual comfort for
the patient.
• Auto adjustment cannot be performed for the night data.
