Partial topography-guided surface ablation, combined with corneal collagen crosslinking when visual acuity is still quite good, optimises prognosis for the patient with keratoconus.

Impairment of corneal sensory innervation causes reduction of both protective reflexes and trophic neuromodulators that are essential for the vitality, metabolism, and wound healing of the ocular surface.

Patients can benefit from short-term, on-label treatment with a novel loteprednol formulation.
