Background: The Implantable Collamer Lens (ICL) has gained recognition in refractive surgery for its stability and ability to achieve reversible refractive outcomes. Aim: Our study seeks to assess the safety and efficacy of the ICL with a central hole for vision correction procedures within the Lebanese population. Through this investigation, we aim to enhance our understanding of ICLs and their applicability in refractive surgeries, thus contributing valuable insights to the existing body of knowledge in this field. Methods: We conducted a prospective cohort study spanning two years. The study included 116 eyes of 58 patients who underwent surgical implantation of the Visian ICL V4c model. The participants were patients aged between 20 and 45 years, with a stable history of refraction and a medical history of myopia ranging from −2.00 to −20.0 diopters (D) and cylinder up to 3 D. Refractive outcomes, intraocular pressure, and corneal endothelial cell were evaluated one year and two years post operatively. Results: During the two years of follow-up, we observed a significant decrease in the UDVA (uncorrected distance visual acuity), CDVA (corrected distance visual acuity), SPH (sphere), CYL (cylinder), and SPH EQ (sphere equivalent). However, there was no variation in the IOP (intraocular pressure) recorded, and the ECC (endothelial cell count) remained stable during the first year following the surgery, but decreased slightly during the second year. Furthermore, we found that an increase in the anterior chamber depth value is associated with a decrease in ECC loss. Importantly, no complications were noted during the two years of postoperative follow-up. Conclusion: The implantation of the ICL is a safe and effective treatment for myopic astigmatism, improving visual acuity without complications.

“…Old age (> 40 years), high myopia (< −12.0D), and low vault (< 230 μm) are risk factors for cataract progression ( 27 ). In long-term follow-up studies of patients with central-hole ICLs over 5 years, the incidence of anterior subcapsular cataracts was 0.53%, whereas that of nuclear cataracts was 0.08% ( 28 ). Notably, nuclear cataract occurrence is associated with age and not influenced by ICL implantation ( 18 ).…”

IntroductionMyopia is causing a major public health concern, with its prevalence increasing globally. This study aimed to discuss posterior chamber phakic intraocular lens (pIOL) research publication trends and hotspots over the past 20 years.MethodsBibliometric analysis was performed using the Web Science Core Collection to investigate posterior-chamber pIOL research publication trends. The extracted records were analyzed, and a knowledge map was built using VOSviewer v.1.6.20. The analysis included visualizing the annual publication count, countries/regions distribution, international and institutional collaborations, author productivity, and journal contribution, in addition to identifying knowledge bases and hotspots. Burst keywords were extracted using CiteSpace v.6.1.R.ResultsIn total, 791 articles on posterior chamber pIOLs published between 2003 and 2023 were retrieved. China had the highest number of publications, whereas Japanese papers received the most citations. Fudan University had the highest number of publications, with articles from Kitasato University having the highest number of citations. Regarding individual research, Xingtao Zhou has published the most significant number of articles, and Shimizu Kimiya had the highest number of citations. The top productive/influential journal was ‘Journal of Cataract & Refractive Surgery’. The top cited references primarily focused on reporting the clinical outcomes of implantable collamer lens (ICL) for individuals with moderate to high myopia. The keywords primarily formed four clusters: posterior chamber pIOL clinical outcomes for myopic astigmatism correction, posterior chamber pIOL implantation complications, ICL size selection and postoperative vault predictions, and postoperative visual quality following posterior chamber pIOL implantation.ConclusionThis study presents the first bibliometric analysis of research trends in posterior chamber pIOL over the past two decades. We investigated the current state and emerging trends of global collaboration and research focal points in this field, offering fresh insights and guidance for researchers.

“…More than 2 million of these pIOLs (Visian and EVO) have been implanted worldwide to date. 1 In the United States, ICL use has grown rapidly since 2022, when the Food and Drug Administration approved the EVO lens, its toric equivalent, and a version with a larger optic diameter (EVO+). More than 100 scientific papers analyzing the performance of EVO and EVO+ lenses have been published.…”

More than 2 million implantable collamer lenses (ICLs) have been implanted worldwide. With a central port to improve aqueous flow through the ICL, the latest iteration of this phakic intraocular lens (pIOL) has been shown to have stable outcomes with very low rates of adverse events. However, correct planning and ICL size selection continue to be important to achieve an optimal vault. Shallow or excessive vaults are not complications in and of themselves but may increase the risk of complications. Historically, surgeons have relied on measurements of anterior chamber depth (ACD) and manual, caliper-measured white-to-white (WTW) distance to select the ICL size. New diagnostic and imaging technologies such as optical coherence tomography (OCT) and ultrasound biomicroscopy (UBM) provide additional opportunities for visualization and measurement of the intraocular dimensions involved in phakic intraocular lens implantation, including sulcus-to-sulcus (STS) and angle-to-angle (ATA) diameters. This paper reviews various approaches to ICL planning and sizing that have been published in the peer-reviewed literature, all of which produce acceptable results for predicting vault and size selection. Surgeons may also want to identify a methodology for patient evaluation and ICL size selection that best aligns with their personal preferences, diagnostic technology, and familiarity with analytical optimization tools.
