Reply: Etiology of negative dysphotopsia

摘要

The comment by Hong et al. that the type 2 shadow would be outside the normal visual field for the nominal location (0.5 mm) behind the iris is true, as we state in the text and demonstrate in Figures 3, 4, and 6. We also state that the type 2 shadow (not ND) would be seen in the visual field only if the IOL were 2.3 mm or more behind the iris and this extreme depth would be very apparent to a clinician. Hence the type 2 shadow is not ND.
