IOT Details Accommodative Lag Implications for Myopia and Pre-Presbyopia Lens Selection

Indizen Optical Technologies (IOT) published an article analyzing accommodative lag as a continuous clinical variable affecting lens selection from childhood myopia through pre-presbyopia. The text defines lag as the gap between accommodative stimulus and response, noting that values above 1.00 D in patients aged 5 to 39 warrant investigation. It distinguishes lag from amplitude, explaining that elevated lag can signal binocular vision issues before presbyopia onset. Citing studies like CLEERE, the article notes myopic children often exhibit double the lag of emmetropes, though causality with axial elongation remains debated. IOT highlights its MyoLess lens, which uses free-form peripheral defocus to address these findings. The company specifies that MyoLess is currently offered only in non-US markets.
