Purpose: This study aims to investigate the influence of anterior chamber depth (ACD) and vault on the anterior chamber angle (ACA) morphology in myopic individuals implanted with posterior chamber phakic intraocular lenses.
Methods: This retrospective case series involved 231 eyes receiving a 13.2-mm implantable collamer lens (ICL).
Article Synopsis
- - The study investigates factors predicting the postoperative horizontal trabecular iris angle (TIA 750) following surgery for a specific type of intraocular lens (IOL) in patients at an ophthalmology clinic in Spain.
- - A total of 330 eyes were analyzed, with significant measurements taken before and after surgery, revealing that the TIA 750 decreased from an average of 42.9 degrees to 24.4 degrees post-surgery.
- - Key predictors for the postoperative TIA 750 include preoperative TIA 750, cornea sagittal depth, and anterior chamber depth, with models achieving reasonable accuracy in prediction (adjusted R² = 0.39).
Clinical Relevance: Biometric measurements in the context of myopia are fundamental to detect eyes at risk of developing myopia and during the follow-up of patients with myopia control treatment. Thus, the accuracy of biometers has high clinical relevance.
Background: The Myopia Master is a new biometer based on partial coherence interferometry especially dedicated to the follow-up of myopic patients.
Purpose: To determine the influence of implantable collamer lenses (ICL) geometry, i.e. spherical and toric on the vault, and report the refractive and visual outcomes of patients bilaterally implanted with the two ICL geometries.

Methods: This study reports a retrospective case series of the first operated eye in 360 patients implanted with myopic spherical or toric ICL. Preoperatively, white-to-white (WTW), central keratometry (Kc) and central corneal thickness (CCT) were measured using the Pentacam.
Purpose: The distance between an implantable collamer lens (ICL) and the crystalline lens, namely vault, is a space regulated by the interaction of the ICL and the anatomical structures of the eye. This study analysed the differences in vault size between fellow eyes with similar anterior segment biometry.
Patients And Methods: A retrospective case series analysed 109 cases of patients bilaterally implanted with EVO-V4c.
Purpose: To determine patient preoperative anatomical features and the parameters of implantable collamer lenses (ICLs) relevant in explaining vault variability.
Setting: Ophthalmology Clinic Vista Sánchez Trancón, Badajoz, Spain.
Design: Retrospective case series.
