From: Changes in corneal higher-order aberrations during treatment for infectious keratitis
Slit-lamp and anterior segment optical coherence tomography images of a representative case of Acanthamoeba keratitis. (a,b) Before treatment, radial keratoneuritis is observed near the centre of the cornea to the nasal and inferior corneas. (c,d) The corneal higher-order aberration (HOA) (total, 6 mm) is 1.55 μm, and the logMAR best spectacle-corrected visual acuity (BSCVA) is 0.046. (e–h) The patient is treated with ophthalmic drops, and healed with corneal scarring. The corneal HOA (total, 6 mm) is 0.98 μm, and the logMAR BSCVA improved to − 0.08 after treatment, although a mild scar remains near the centre of the cornea.
