Role of microfluctuations in accommodation: a novel approach to reduce non-accommodative noise [PDF]

International Journal of Ophthalmology, 2019
Accommodative response and its possible role in myopia development has been explored through the study of the microfluctuations (MFs) of accommodation, which are commonly divided in high (1.0 to 2.3 Hz) and low (0.1 to 0.6 Hz) frequency components ...
