| drS786 Total Posts: 54 | Posted: Sun Oct 12, 2008 06:40 pm Cycloplegia hypermetropia or presbyopia do not “clear up in two minutes.” Accommodative inertia typically occurs when the accommodative system is capable of but slow in making a change. In other words there is a considerable lag between the stimulus and response (starting trouble). Accommodative inertia, also called as accommodative infacility, can be defined as slow or difficult accommodative response to dioptric change—Unstimulus. |
