This study is a single-arm, clinical evaluation study of vault height and refraction, after successful ICL implantation. Subjects will be assessed pre-operatively, operatively, at 1 week postoperatively, and 1, 3, and 6 months post-operatively. Clinical evaluations will include measurement of monocular and binocular visual acuity, manifest refraction, and vault height.
The objective is to develop and evaluate an algorithm for implantable collamer lens (ICL) sizing that uses high frequency ultrasound biomicroscopy (UBM) for vertical placement.
