Introduction: This study evaluated the clinical outcomes of simultaneous implantable collamer lens (ICL) removal and phacoemulsification with intraocular lens (IOL) implantation in a multicenter study.
Methods: We retrospectively investigated 83 eyes of 72 patients requiring ICL extraction and cataract surgery at five institutions. Preoperatively and 3 months postoperatively, we determined visual acuity (logMAR), spherical equivalent refraction, and endothelial cell density (ECD), in addition to the preoperative backgrounds and the postoperative complications.

Purpose: To design formulas for predicting postoperative vaults in vertical implantable collamer lens (ICL) implantation and to achieve more precise predictions using machine learning models.
Design: Retrospective, observational study.
Setting: Eye Clinic Tokyo.
Background: To assess the multicenter outcomes of posterior chamber phakic intraocular lens implantation with a central hole (EVO-ICL, STAAR Surgical) for patients undergoing previous laser in situ keratomileusis (LASIK).
Methods: This case series enrolled 31 eyes of 21 consecutive patients undergoing EVO-ICL implantation to correct residual refractive errors after LASIK at 7 nationwide major surgical sites. We investigated safety, efficacy, predictability, stability, and adverse events at 1 week, 1, 3, and 6 months postoperatively, and at the final visit.
To assess the multicenter clinical outcomes of the implantation of hole implantable collamer lens (Hole ICL, ICL KS-AquaPORTTM; STAAR Surgical, Nidau, Switzerland) in patients of 45 years or more. We retrospectively assessed the surgery's safety, efficacy, predictability, stability, and adverse events before surgery and after the surgery at 1 week; 1, 3, and 6 months; and 1 year, followed by once every year for approximately 2.2 years.

We retrospectively reviewed all cases of ICL dislocation at four major refractive surgery centers in Japan until December 2019. The incidence, patient background, cause of dislocation, complications of repositioning surgery, and postoperative visual function were investigated.

Settings: Four refractive surgery centers.
Design: Prospective randomized multicenter single-masked comparative study.
This study was aimed to assess the clinical outcomes of Visian ICL (hole ICL; STAAR Surgical, Inc.) implantation for the correction of myopic refractive errors in eyes having an anterior chamber depth (ACD) below the current manufacturer's recommendation (<3.0 mm).

Methods: This multicentre retrospective case series comprised 351 eyes of 351 consecutive patients undergoing ICL implantation. Eyes were divided into groups based on preoperative degree of myopia: group 1; 57 eyes, manifest spherical equivalent less than -6 dioptres (D), and group 2; 294 eyes, -6 D or more.
Purpose: To evaluate the efficacy of laser epithelial keratomileusis (LASEK).
Subjects And Method: LASEK was performed on 82 eyes of 42 patients whose spherical refraction ranged from -0.75 to -12.
