Treatment of paracentral corneal scar-induced astigmatism with manual superficial keratectomy

ABSTRACT

Superficial, paracentral corned scars may markedly reduce visual acuity by inducing significant central corneal steepening and irregular astigmatism. Two cases are presented which provide topographic correlation of reduction of central corned astigmatism and improvement in visual acuity following manual superficial keratectomy. In both cases, manual superficial keratectomy was preferred to phototherapeutic keratectomy to avoid the risk of iatrogenic induction of a change in the baseline spherical or astigmatic refractive error
