PURPOSE: To investigate the safety and efficacy of implanting a posterior chamber implantable collamer lens with a central hole in cases of high myopia with peripheral primary iris or ciliary body cysts. METHODS: A total of 37 eyes of 19 patients with primary iris or ciliary body cysts detected by ultrasonic biological microscope were included, with spherical powers of -10.26 ± 3.28 D and cylinder powers of -1.71 ± 1.18 D. Each patient received ultrasonic biological microscope and a routine examination before implantation of the implantable collamer lens...

We describe a technique for the application of femtosecond laser-assisted cataract surgery in eyes with cataract and previous implantation of a foldable anterior or posterior chamber phakic intraocular lens (pIOL). In 2 eyes with an anterior chamber pIOL (angle-supported Acrysof Cachet) and 3 eyes with a posterior chamber pIOL (2 eyes with an Implantable Collamer Lens pIOL; 1 eye with a Phakic Refractive Lens), a femtosecond laser was used to create a capsulotomy, perform lens fragmentation, and create corneal incisions with the pIOL in situ...

PURPOSE: To report an interesting phenomenon, after vitreoretinal surgery, in an eye with toric implantable collamer lens (ICL). METHODS: A 20-year-old male presented with raised intraocular pressure (IOP) after the retinal detachment surgery in the left eye. He had toric ICL in both the eyes, and left eye showed shallow peripheral anterior chamber depth (ACD), narrow iridocorneal angle (ICA), increased ICL vault and pigments debris blocking central hole. After dilation, peripheral ACD deepened, ICL vault decreased and ICA increased, with posterior bowing of iris...

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), and the V4 ICL sizes were then converted to V4c ICL sizes with a size-converting table...

PURPOSE: To describe the good outcome of implantable collamer lens (ICL) rotation to reduce post-operative vault. METHODS: Retrospective analysis of case report. A 43-year-old woman had V4c EVO + myopic non-toric ICL implantation and post-operatively she presented with anisocoria and high vault. She underwent surgery to rotate the ICL 90 degrees to a vertical orientation. RESULTS: We achieved a reduction in the vault from 1020 to 486 μm after vertical ICL rotation...

PURPOSE: To assess the light reflex of the pupil after Implantable Collamer Lens (ICL) (KS-aquaPORT; STAAR Surgical, Nidau, Switzerland) implantation to determine whether the ICL implantation might affect the pupil dynamics. METHODS: This study examined 28 eyes of 28 consecutive patients who underwent implantation of the posterior phakic ICL for the correction of myopia and astigmatism. Patient age at the time of surgery was 31.1 ± 6.8 years (range: 25 to 42 years)...

REVIEW
Jeewan S Titiyal, Manpreet Kaur, Ruchita Falera
Intraoperative optical coherence tomography (iOCT) is a noninvasive imaging modality that provides a real-time dynamic feedback of the various surgical steps. Comprehensive literature search was performed in MEDLINE using "intraoperative optical coherence tomography" and "iOCT" as keywords. The use of iOCT as an aid to decision-making has been successfully reported in cases undergoing keratoplasty, implantable Collamer lens (ICL) implantation as well as cataract surgery. iOCT helps to assess the graft-host relationship in penetrating keratoplasty...

PURPOSE: To evaluate long-term refractive outcomes of implantable collamer lens (ICL) implantation and late postoperative complications. METHODS: We assessed outcomes of patients who underwent ICL implantation (type ICM V4 for myopia, ICH V3 for hyperopia, TICM V4 for astigmatism) in our department between 1998 and 2013. It comprised 62 eyes (40 myopic and 22 hyperopic). The average follow-up period was 10.5 years. We evaluated: uncorrected and best-corrected visual acuity (UCVA and BCVA), spherical equivalent (SE), ICL vault, endothelial cell density and late postoperative complications...

The new type implantable Collamer lens with a central hole (V4c-ICL) is widely used to treat myopia. However, halos occur in some patients after surgery. The aim is to evaluate the effect of V4c-ICL implantation on vision-related daily activities. This retrospective study included 42 patients. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), intraocular pressure (IOP), endothelial cell density (ECD), and vault were recorded and vision-related daily activities were evaluated at 3 months after operation...

Purpose. To evaluate the anterior segment, the anatomical position of the implantable collamer lenses (ICL), and its relationship to adjacent ocular structures using Ultrasound Biomicroscopy (UBM). Methods. In a prospective study, 142 myopic eyes of 93 patients implanted with Visian ICL were subjected to UBM examination between March 2010 and January 2015. The relative position of ICL to the adjacent structure and the overall iris configuration were evaluated. The machine calibers were used to measure the minimum central distance between the ICL and anterior lens capsule (vault) and the vertical central distance between the corneal endothelium and the ICL (E-ICL)...

BACKGROUND: To objectively compare the early changes in vault over time following implantation of an Implantable Collamer Lens without (ICL V4) and with (ICL V4c) a central hole and the respective factors affecting vault change in moderate to high myopia. METHODS: This prospective study comprised of 38 eyes of 38 patients implanted with ICL V4 and 39 eyes of 39 patients implanted with ICL V4c intraocular lenses. We quantitatively assessed the postoperative values of vault and pupil size at 1 day, 1 week, and 1 month following implantation using a rotating Scheimpflug camera (Pentacam)...
