“…18 Through correlation and regression analyses, we found that the vaults of eyes with similar anatomy were similar. The result is similar to the study of Martínez-Plaza et al 16 who reported that the vault obtained in the second implanted eye was highly related to the vault observed in the first one during the whole follow-up. However, the mean ΔE of the vault was 74.59 ± 55.59 μm, and the 95% CI was −34.4 ~ 183.6 μm one month after surgery.…”

“…Nakamura et al obtained the NK formula by incorporating anterior chamber width and crystalline lens rise into the calculation of ICL size, which greatly improved the proportion of the ideal postoperative vault. 13,14 Kamiya et al, 15 Martinez et al, 16 and Cerpa et al 17 concluded that the vault obtained in both eyes was highly correlated. We aimed to measure the clinical data of patients with similar anterior segment anatomy who were implanted with ICLs of the same model placed in the same position and analyze the common range and factors affecting the vault inter-eye difference.…”

Purpose The safety and stability of implantable collamer lens (ICL) implantation are closely related to the vault. We aimed to assess clinical data from patients with similar anterior segment anatomy who received ICL of the same model placed in the same position and analyze common range and factors affecting the vault inter-eye difference. Patients and Methods A prospective study was performed, including 162 eyes of 81 patients with a bilateral ICL (V4c) implantation. Subjects were evaluated before the surgery and 1 day, 1 week, and 1 month postoperatively, and they were divided into 4 groups based on the ICL size. Bivariate correlation and multiple linear regression (stepwise) analyzed associations between vault inter-eye differences and horizontal sulcus-to-sulcus diameter, anterior chamber depth, lens thickness, ICL size, spherical equivalent, and vault. Results One month after surgery, mean vault inter-eye differences were 74.59 ± 55.59 µm. Nearly 70% of patients presented with vault inter-eye differences lower than 100 µm. The second eye vault variance of 69% was attributed to the first eye vault. Vault inter-eye differences were positively correlated with ICL spherical equivalent (regression equation: vault inter-eye differences (μm) = 139.415 + 6.295 × ICL spherical equivalent). Vaults after ICL implantation were similar in fellow eyes, with some considerable differences. The 95% confidence interval of the vault inter-eye difference was −34.4 ~ 183.6 μm. Conclusion In eyes with similar anterior segment anatomy, there is a 95% probability that the vault will vary from −34.4 μm to −183.6 μm when a similar ICL is implanted. These results can help surgeons to select an appropriate ICL size to achieve an ideal vault. The smaller the spherical equivalent, the larger the difference between the two vaults, which provides a reference for size in moderate myopia. ICL spherical equivalent affects and predicts vault inter-eye differences after ICL implantation.

“…A study by Martinez-Plaza et al examining 40 eyes of 20 patients undergoing bilateral EVO+ ICL implantation found the vault of the first eye implanted at postop day 1 of these patients highly predicted the vault of the second implanted eye ( R 2 = 0.87 and P <0.001) with mean inter-eye difference of −0.95 µm. 31 These evidence-based considerations can aid the clinician in making decisions on further ICL implantation or reimplantation given a particular vault height.…”

To provide a comprehensive guide of all implantable collamer lens (ICL) sizing nomograms and the respective preoperative diagnostic devices that are required. This guide would help clinicians in choosing the appropriate ICL size for myopic patients to optimize postoperative vault height. Methods: A literature search of peer-reviewed journals describing methods and postoperative outcomes of ICL sizing was conducted. Research articles containing ICL nomograms or formulas were identified from this search. Preoperative variables necessary for these nomograms and the required diagnostic devices to measure these parameters such as topography, biometry, or ultrasound biomicroscopy (UBM) were noted. An additional search was conducted to identify artificial intelligence (AI) or machine learning (ML)-derived nomograms. Results: Eighteen ICL sizing nomograms were identified through literature search. Five of these nomograms are available for use and require topography or biometry devices. Of these, four include the manufacturer's, optimized white-to-white (WTW), Kang, Kim, and Rocamora Nomograms. Eight of the 18 nomograms available for use require UBM. Eight of these include the Kojima, Nakamura, KS, ZZ, Dougherty, Parkhurst, Russo, and Reinstein Nomograms. Four of the 18 nomograms are ML-derived including Shen, Rocamora, Russo, and Kang Nomograms. Conclusion: ICL nomograms are a vital tool in helping clinicians select the right ICL size for myopic patients to optimize postoperative vault reducing risk of postoperative complications. Based on available diagnostic devices such as topography, biometry, or UBM clinicians can integrate specific nomograms into practice.

“…[6] The current models of posterior chamber phakic IOLs, particularly with the Visian™ implantable collamer lens (ICL, EVO+ V5, Staar Surgical, Monrovia, CA), have achieved good refractive and safety results. [7][8][9] Owing to the extended use of this implant by an increasing number of young patients, the design and material of this implant need to be constantly improved. In recent years, a new posterior chamber phakic IOL, the implantable phakic contact lens (IPCL) (IPCL V2.0, Care Group Sight Solution, India), has become available, with a substantial financial advantage over ICL.…”

This study aimed to compare the postimplantation clinical outcomes of 2 types of posterior chamber phakic intraocular lenses (IOLs): Visian™ implantable collamer lenses (ICL; EVO+ V5; Staar Surgical, Monrovia, CA) and an implantable phakic contact lens (IPCL) (IPCL V2.0, Care Group Sight Solution, India) to correct high myopia and myopic astigmatism. This retrospective study included patients who had undergone phakic IOL implantation performed by a single surgeon between March 2021 and March 2022. Preoperative assessments included slit-lamp examination, fundus examination, spherical equivalent, uncorrected distant visual acuity (UDVA), corrected distant visual acuity (CDVA), specular microscope parameters, and optical quality analysis system parameters. Postoperative assessments after 1 year included slit-lamp examination to detect adverse effects and spherical equivalent, UDVA, CDVA, specular microscope, optical quality analysis system, and anterior-segment optical coherence tomography. Eighty eyes from 42 patients (47 eyes from 24 patients in the ICL group and 33 eyes from 18 patients in the IPCL group) were included. No statistically significant differences were observed between the 2 groups regarding preoperative parameters. At 1-year postoperatively, the mean UDVA in the ICL and IPCL groups was 0.019 ± 0.040 logMAR and 0.019 ± 0.041 logMAR, respectively. The mean CDVA was 0.001 ± 0.008 logMAR and 0.001 ± 0.007 logMAR in the ICL and IPCL groups, respectively, showing no statistically significant differences. The postoperative parameters did not differ significantly between the 2 groups. The visual acuity and refractive results of both groups were excellent, and both groups exhibited similar efficacy and safety profiles.
