A dilated fundus examination and
additional diagnostic testing should be performed
if clinically applicable, especially if postoperative
visual acuity is less than expected [2&&]. Optical
coherence tomography (OCT) and/or fluorescein
angiography can evaluate macular diseases such as
cystoid and diffuse macular edema, epiretinal
membranes and age-related macular degeneration
(AMD). Similarly, corneal topography can diagnose
irregular corneal astigmatism and an automated
visual field examination may help characterize a
neuro-ophthalmic abnormality. Other testing may
be helpful in the right clinical setting.
