    Intrastromal femtosecond astigmatic keratotomy is a promising technique to correct astigmatism following cataract surgery. Compared with other methods, it induces no epithelial injury, and both the procedure and recovery are quick. Dr. Steven Schallhorn shares an analysis of early outcomes that suggest the procedure can safely reduce moderate levels of astigmatism with no change in the mean spherical equivalent. While the correction ratio indicated slight undercorrection, Dr. Schallhorn believes further refinement of the nomogram will improve the predictability of outcomes.
