Purpose

To assess the agreement of decentration measurements between tangential curvature topography and tomography pachymetry difference maps after a small-incision lenticule extraction (SMILE) procedure.

Setting

Yonsei University College of Medicine and Eyereum Eye Clinic, Seoul, South Korea.

Design

Retrospective case series.

Methods

Decentrations and pupillary offset (angle κ) were analyzed and compared using two different methods. A difference map of the tangential curvature was generated with a Placido corneal topographer (Keratron Scout) and a pachymetry difference map was generated with a Scheimpflug tomographer (Pentacam) for each eye,

The purpose of this study is to assess the agreement of decentration measurements between tangential curvature topography and tomography pachymetry

difference maps after a small-incision lenticule extraction (SMILE) procedure.

Conclusion of this study,

although there was no significant difference between the scalar magnitude of decentration with the tangential topography difference maps and tomography pachymetry difference maps,

the vector differences did not agree and increasing error was present with increasing differences in pupillary offset in the pachymetry difference maps.

We will continue to study for safer surgery.
