AI Article Synopsis
- The study aimed to determine if cannula displacement during cataract surgery with Luer locks is a common issue, surveying U.K. ophthalmologists.
- Results showed 60 reported cases of cannula detachment, primarily due to stromal hydration (50%), with some serious complications like retinal damage (9%) and vitreous loss (17%).
- The authors recommend that surgeons ensure a secure connection when using the cannula and use a new one for each stage of the operation, especially for viscoelastic.
Article Abstract
Objective: To ascertain whether cannula displacement during cataract surgery with the use of the Luer lock is a common and recognized complication.
Methods: A questionnaire was sent to attending physicians on the Royal College of Ophthalmologists U.K. register inquiring about episodes of cannula displacement and complications.
Results: Despite the use of Luer locks, 60 cases of cannula detachment were reported; 196 respondents experienced this complication, and the most common cause of cannula detachment was stromal hydration (50%). Hydrodissection and viscoelastic were experienced by 18% and 17%, respectively. No severe damage resulted in most cases (76 cases), but some serious complications were reported: retinal damage (9%) and vitreous loss (17%).
Conclusions: We recommend that surgeons test the union carefully themselves and then test the system by squirting outside the eye. Additionally, we recommend that a new cannula be used for each stage of the procedure. The viscoelastic cannula, in particular, should not be used for any other purpose.

Article Synopsis
- Choroidal detachment (CD) during retinal detachment surgery can negatively affect surgical results and vision, necessitating specific management techniques.
- Cannula-guided choroidal drainage is essential for mitigating pre-existing CDs, especially in complex cases with hemorrhagic detachment.
- Intraoperative sudden CD can be caused by issues like hypotony or air entry from cannula slippage, which may lead to serious complications like Venous Air Embolism (VAE); prompt action to stop air infusion is critical to prevent life-threatening outcomes.

Purpose: To compare functional and anatomical outcomes between posterior drainage of residual fluid using a 41G cannula, fluid tolerance (R-SRF), and conventional complete drainage methods, including removal through peripheral retinal breaks (PRB), perfluorocarbon liquid (PFCL), and posterior retinotomy (PR).
Methods: In this retrospective, multicenter study, we evaluated cases for visual acuity (VA) at 3 months of follow-up. Secondary outcomes included surgical success, postoperative metamorphopsia, shifts, full-thickness folds (FTF), optical coherence tomography (OCT) parameters, and safety.

Objective: The goal of minced cartilage implantation (MCI) is to restore an intact cartilage surface in focal osteochondral lesions of the humeral capitellum.
Indications: The indications for MCI are limited osteochondral lesions at the humeral capitellum, also at the head of the radius, with intact cartilage border as well as in situ or a completely detached fragment, and free joint bodies (grade II-grade V according to Hefti).
Contraindications: Contraindications for MCI are already concomitant or associated cartilage damage as well as bilateral osteochondral lesions and insufficient available cartilage material.
