Nomogram for limbal relaxing incisions

I would like to congratulate Kaufmann et al.1 on their article comparing limbal relaxing incisions (LRIs) with on-axis phacoemulsification surgery. The authors validate the use of LRIs to reduce preexisting astigmatism at the time of cataract and intraocular lens surgery, a practice many authors have advocated in recent years to provide patients with an optimal refractive outcome.2 This paper nicely supports the safety and efficacy of this technique. I would, however, like to point out what I believe is a minor oversight. The authors refer to their nomogram, Table 1, as a “modified Gills nomogram.” In actuality, this nomogram is identical to one I have published, taught, and promulgated within the ophthalmic community for a number of years (L.D. Nichamin, MD, “Peripheral Arcuate Keratotomy,” Ocular Surgery News, March 15, 1996; “Correcting Astigmatism During Cataract Surgery,” EyeNet Magazine, June 2005).3–9 This distinction is made not to imply that one nomogram is superior to another, but rather to clarify the point within the refereed literature and to help future authors and investigators maintain consistent measures and parameters for comparison.
