Late-onset corneal haze after intrastromal corneal ring implantation in an eye with previous topography-guided PRK.

ABSTRACT:

Purpose

To report a case of late-onset corneal haze 3 months after intrastromal corneal ring segment (ICRS) implantation in an eye with previous transepithelial topography-guided photorefractive keratectomy (TG-PRK).

Observations

A 40-year-old woman with stable keratoconus for 10 years underwent limited TG-PRK with mitomycin C in both eyes for mixed astigmatism. After four years, with atopic symptoms worsening and eye rubbing, the patient presented keratoconus progression in the left eye with increased irregular astigmatism. An ICRS was implanted with initial improvement in vision. Three months later severe subepithelial haze was observed along the ring groove.

Conclusion and importance

This is the first report of subepithelial haze after ICRS implantation. This repor
