BACKGROUND The purpose of this study was to identify factors related to the unexpected vault in V4c implantable collamer lens (ICL; STAAR Surgical) implantation. METHODS V4c ICLs were implanted in 43 eyes of 43 patients for the correction of myopia. The implanted V4c ICL sizes were determined individually with our previous V4 ICL sizing nomogram based on the sulcus-to-sulcus diameter (STS), a...

AIM: To elucidate the safety and visual quality of implantable collamer lens with central hole (ICL V4c) implantation for correcting moderate high myopia at least 5y. METHODS: This retrospective study was conducted on 58 patients (114 eyes) who were followed up 5y after ICL V4c implantation. The observation done before 1d, 1mo, 1 or more surgical procedure. acuity, subjective refraction, intrao...

PURPOSE To evaluate the visual outcome and intraocular pressure changes after Visian Implantable Collamer Lens (ICL) implantation V4b and V4c (with central hole) for correction of high myopia. METHODS A prospective, consecutive, interventional comparative case series of V4b and V4c ICL implantation was done in high myopic patients who were unsuitable for laser vision. The main outcome measure...

INTRODUCTION The objective of this study was to evaluate the changes of the anterior chamber (AC) of the eye after implantable Collamer lens (ICL) implantation in high myopia by using the Pentacam. METHODS The prospective study included 34 high myopic patients (34 eyes). All patients were treated with Visian implantable Collamer lens (ICL) (Staar Surgical Co.) implantation. The Pentacam (Ocul...
