Research Article: Influence of Preoperative Parameters on the Ratio of Keratometric Change per Diopter of Attempted Spherical Equivalent (?K/?SEQ) for Myopic Correction Within LASIK, PRK, and SMILE

Date Published: 2023-08-29

Introduction:
Refractive surgery has emerged as a safe and reliable treatment for correcting myopia and astigmatism. As the field continues to develop, clinicians continue to find new methods to optimize visual outcomes for their patients. One such method is accounting for the change in keratometry relative to the change in spherical equivalent from preoperatively to postoperatively. This value (?K/?SEQ ratio) has a known value of .–. and has been shown to be larger in smaller refractive error corrections and vice versa. This…
