Precision in refractive surgery is a cornerstone of achieving optimal visual outcomes, whether the selected procedure uses a cornea- or lens-based approach.
For phakic IOL implantation specifically, accurate sizing and placement of the lens are crucial to ensure a proper fit and rotational stability within the eye. Traditional sizing methods rely on white-to-white (WTW) measurements to assess the horizontal distance between the visible scleral edges (limbus) of the eye. There is growing recognition, however, that gray-to-gray (GTG) measurements may offer a more accurate and reliable method for
