Mechanized astigmatic arcuate keratotomy with the Hanna arcitome for astigmatism after keratoplasty

Arcuate keratotomy performed with the Hanna arcitome was effective in reducing post-keratoplasty astigmatism. The device enabled safer, easier arcuate incisions than with manual techniques. However, predictability and efficacy could be improved by a more accurate nomogram.
