Fig. (4) Comparative plots of a) post-therapy peak NAFX vs pre-therapy peak NAFX and b) post-therapy LFD vs pre-therapy LFD during fixation of far targets with contact lenses, with acetazolamide, and during convergence at 60 PD. Curves shown are the estimated peak NAFX and LFD for the tenotomy and reattachment (T&R) procedure.
