Purpose:The purpose of this study was to compare keratometry and anterior chamber depth (ACD) measurements from the Lenstar LS 900 (Haag-Streit AG, Switzerland) and the Pentacam (Oculus, Weltzar, Germany), and compare the keratometry readings of these two systems to a manual keratometer (MK), (Haag-Streit, Switzerland).Materials and Methods:In this prospective study, keratometry and ACD measurements were obtained in 50 eyes of 50 normal subjects with the Lenstar and the Pentacam. Keratometry was also measured using a MK. Correlation, comparison, and interdevice agreement was evaluated using intraclass correlation analysis, Wilcoxon test, and Bland-Altman plots.Results:The keratometry and ACD measurements obtained from the Lenstar and the Pentacam showed excellent correlation. The mean interdevice differences in mean keratometry (Km) for the Lenstar and the Pentacam, the Lenstar and the MK, and the Pentacam and the MK were 0.39 D, 0.10 D, and 0.30 D respectively; and the 95% limits of agreement (LoA) for Km were 0.04-0.82 D; −1.90-2.10 D; and −2.30-1.70 D, respectively. The mean interdevice difference in ACD for the Lenstar versus the Pentacam was 0.09 mm, with 95% LoA of 0.23-0.05 mm.Conclusions:The ACD measurements obtained using the Lenstar and the Pentacam seem to be interchangeable, whereas, the keratometry measurements obtained using the Lenstar, Pentacam, and MK differ considerably, and are not interchangeable.

Background: The aim of the study was to evaluate the management and outcomes of the patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a secondary hospital. Methods: A total of 699 hospitalized patients who had positive rRT-PCR for SARS-CoV-2 and/or typical findings of COVID-19 at chest computed tomography (CT) were enrolled in this study. Demographics, comorbities, initial laboratory tests on admission, treatment modalities, complications and outcomes were evaluated retrospectively. Results: The mean age was 57.0±15.6 (range:16-94 years), and male:female ratio was 1.24. 58.7% of the patients had at least one underlying comorbidity, the most common was hypertension. 72.8% of the patients had positive RT-PCR. 18.1% of the patients had lymphopenia, 35.7% hyperferritinemia, 58.3% increased lactate dehydrogenase, and 58.5% increased D-dimer. Chest CT revealed moderate and severe stage in 57.9% of the patients, and bilateral lung involvement in 78.7%. Hydroxychloroquine was given to 37.2% and favipiravir 67.1% of the patients. No significant difference was observed between treatment groups in terms of mortality (P=0.487). 5.8% of the patients were transferred to the ICU, of whom 75.6% were needed non-invasive and 36.5% invasive mechanical ventilation. The overall case fatality rate was 0.9. Conclusions: Older age, male sex, low lymphocyte count, CT findings including bilateral involvement and severe stage were significantly associated with poor prognosis and mortality.
