In early-stage, stable keratoconus, vision is compromised primarily by irregular astigmatism. Managing this astigmatism appropriately is the central therapeutic objective at this stage of the condition.
Early-stage keratoconus with stable progression, where astigmatic refractive error is the dominant driver of visual impairment. The protocol addresses correction of this astigmatism within the context of disease stability.
The approach at this stage centres on optical correction of astigmatism. One avenue involves conventional refractive correction — the full regimen specifies which modalities apply and under what conditions.
