Background/aim: This study aimed to evaluate astigmatism after cataract surgery by comparing the use of an intraoperative aberrometer combined with an image-guided system (VLynk) an image-guided system alone (Verion) in patients with significant lens opacity.
Patients And Methods: The main outcomes included the corrected distance visual acuity (CDVA), astigmatism, spherical equivalent (SE) status, and the predicting factors for reduced astigmatism in the two groups.
Results: In this study, 73 patients were enrolled in the study group (VLynk); 76 individuals constituted the control group (Verion). Preoperative and postoperative CDVA between both groups were similar (all >0.05). The postoperative cylinder power (=0.002), postoperative SE (=0.004), and the difference between real SE and estimated SE (=0.001) were significantly lower in the VLynk group. Implantation of toric IOL was associated with less astigmatism in both groups (both <0.05). Longer axial length (=0.013) and higher central corneal power (=0.023) were correlated with greater astigmatism in the Verion group.
Conclusion: VLynk is correlated with better postoperative astigmatism control and predictability compared to Verion in patients with significant lens opacity.

The favorable success rate in cancer treatment predominantly depends on precise diagnosis with target-specific drug delivery, which can regulate the patient survival outcome rate. Moreover, proper tracking of the system's pH is very much crucial as most of the therapeutic's action and release rate depend on it. Therefore, this work has been intended to fabricate a folic acid-derived carbon dot (FACD) decorated with chitosan (Cs) in order to form nanospheres (FACD-Cs-Ns) for anticancer doxorubicin hydrochloride (Dox.

From these, newly developed "anatomical digital twin models" reproduce both the morphological and anatomical characteristics of the organs, including the texture of the tissues they comprise. The aim of the study was to develop and test the new digital twins in the setting of intraoperative guidance during robotic-assisted partial nephrectomy (RAPN).

Background: Robotic systems are increasingly utilised to improve clinical outcomes in prostate interventions.
Methods: We enroled 20 patients to verify the clinical feasibility of transrectal ultrasound (TRUS)-guided robot-assisted prostate biopsy (PBx). For each patient, controlled trials of systematic 12-core PBx were initially conducted manually using a biopsy gun, followed by a 3-core cognitive fusion targeted biopsy performed by the hand-held robot.

Purpose: Lung cancer remains the leading cause of cancer death. This has brought about a critical need for managing peripheral regions of interest (ROIs) in the lungs, be it for cancer diagnosis, staging, or treatment. The state-of-the-art approach for assessing peripheral ROIs involves bronchoscopy.

Background: De-escalating the management of fibroadenoma of the breast has been encouraged, but it is not known whether this has been successful. A better understanding of the costs and benefits of surgical excisional biopsy is essential for managing individual patients and health systems.
Methods: Prospectively maintained data sources from the Johns Hopkins regional health system were used to capture trends in the rate of diagnosis and excision of fibroadenoma of the breast.
