“…Vertical compression by the iris, dampening effect of the ciliary sulcus structure, or innate ICL vault are additional factors that may lead to unexpected vaulting after ICL implantation (6). Ciliary sulcus microcysts have been identified as a source of WTW sizing mismatch with ICL that may require explantation of the ICL (7, 14). In a review by Zeng et al (7) of 616 myopic eyes with previous pIOL implantation, 2.6% cases (16/616) needed a pIOL exchange.…”

“…The vault depends on multiple variables such as WTW, ACD, age, refractive error,[2425] pupil diameter,[26] and the presence of ciliary sulcus microcysts. [27] Consequently, the vault cannot be quantitatively predicted despite some regression models that have been proposed with some of these variables. [28] This means that our recommendations allow the clinician to minimize one of the sources of variability, the variations in the selection of the ICL size depending on the accuracy of WTW measurement.…”

Purpose: To assess the agreement in the white-to-white (WTW) measurement with two different devices, the reproducibility and the probability of confusing sizing (PCS) in selecting a different implantable collamer lens (ICL). Study Design: Retrospective observational case series. Methods: Images of 192 eyes were captured with both devices. The WTW was measured automatically (OA) and manually (OM) with the Orbscan and Keratograph (KA and KM) by one examiner who repeated a total of four measures. A second examiner conducted a single manual measure for each device over the same image. The ICL sizing was computed for each measure of WTW and the PCS was calculated as the percentage of cases for which the confronted or repeated measure resulted in a different size of the ICL. The critical WTWs with highest PCS were identified. Results: KM overestimated the WTW versus OM in 0.13 ± 0.18 mm ( P < 0.001) but not in the automated method comparison, 0.01 ± 0.19 mm ( P = 0.58). Inter-examiner reproducibility ( R ) was higher with OM than with KM, and the intra-examiner R decreased with the average of two measures in both cases. The PCS was higher with the increase of mean differences, the limits of agreement (LoAs), and R . WTWs from 11.1 to 11.2 mm, 11.6 to 11.7 mm, and 12.3 to 12.4 mm resulted in higher PCS. Conclusion: The mean difference is not enough to apply conversions between devices and the LoAs and R should be considered. Special attention should be taken for WTWs with higher PCS.
