What does "SNR" stand for on the IOL Master screen?

Signal-to-noise ratio
Standard number rating
Signal-negative ratio
Signal-noticeable response

The correct answer is: Signal-to-noise ratio

SNR stands for Signal-to-noise ratio, which is a critical measurement in various fields, including ophthalmology. In the context of the IOL Master, SNR is used to assess the quality of the signal that is being processed, particularly during measurements taken for intraocular lens (IOL) calculations. A high signal-to-noise ratio indicates a clearer and more reliable measurement, as the signal (desired data) stands out distinctly from background noise (unwanted interference). This is vital for ensuring accurate assessments, ultimately impacting the precision of IOL placements and patient outcomes in cataract surgery. The other options, while they sound plausible, do not reflect the accurate terminology used in this context, making them incorrect.
