Implication

Clinical study demonstrates wave front-guided PRK reduces refractive errors and aberrations in keratoconus after cross-linking, indicating effective visual improvement within ablation limits.

Key Points

To assess the efficacy of sequential wave front-guided photorefractive keratectomy following corneal collagen cross-linking for correcting refractive errors and higher-order aberrations in keratoconus.
Evaluated sequential wave front-guided photorefractive keratectomy (WFG PRK) using the iDesign high-resolution aberrometer and STAR S4 IR excimer laser after corneal collagen cross-linking (CXL).
Applied the protocol to mild and moderate keratoconus cases with maximum intended ablation depth constrained to ≤15% of minimal corneal thickness.
Sequential WFG PRK effectively corrected spherocylindrical refractive errors in patients with mild and moderate keratoconus.
The intervention minimized higher-order optical aberrations, provided the ablation depth remained within 15% of the minimal corneal thickness.
