title: Transverse keratotomy in postkeratoplasty astigmatism.
abstract: Transverse relaxing incisions were made in 12 eyes with a mean corneal astigmatism of 10.7D following penetrating keratoplasty. A few days later the mean graft astigmatism had been reduced to 5.5D (p = 0.0022), the reduction being significantly correlated to the degree of astigmatism before the keratotomy was done (p = 0.0044). Thereafter the corneal contour remained fairly stable through a mean follow-up period of 28.1 months, although a tendency towards a further reduction of the astigmatism was indicated. The mean corrected visual acuity improved from 0.5 before the keratotomy to 0.7 at the last control visit (p = 0.0117).
