Abstract

A 79-year-old man underwent phacoemulsification (phaco) with TORIC intraocular lens (IOL) insertion combined with Kahook dual blade (KDB) goniotomy of the right eye several months after a stand-alone phaco in the fellow eye. He had significant against-the-rule astigmatism in both eyes (2.41D @ 10° right, 2.40D @ 160° left) preoperatively. Postoperatively, nearly all corneal astigmatism disappeared in the right eye (0.60D @ 37°), while it remained the same in the left eye (2.00D @ 167°). Ophthalmologists should be aware that KDB may have an unreported effect of altering corneal astigmatism, which should be considered when inserting TORIC IOL.
