title: Transverse astigmatic keratotomy. An integral part of small incision cataract surgery.
abstract: Transverse astigmatic keratotomy (TAK) is used with an astigmatically neutral wound to control against-the-rule astigmatism. Previously both wound manipulation and TAK have been used to alter astigmatism, but with the advent of astigmatically neutral small incision surgery, astigmatism control involves TAK alone. This paper discusses the TAK approach to astigmatism control and includes a nomogram for incision size.
