[Surgical video course receives better evaluation than participation in the operating room as part of student teaching].

Background: Imparting knowledge in the operating room represents a particular challenge in student teaching.

Objective: Participation in the operating room was compared with teaching via a surgical video course as part of the block practical course in ophthalmology at the University of Lübeck.

Methods: All students took part in both observation in the operating room and in the video course.

[Efficacy and safety of the new generation of excimer laser trabeculotomy in a heterogeneous patient population-1-year follow-up].

Background: Microinvasive procedures have become established in glaucoma surgery and are preferred for patients with target pressure values that are not too low. Excimer laser trabeculotomy (ELT) represents such a minimally invasive approach and can easily be combined with cataract surgery.

Objective: Over 12 months the reduction in intraocular pressure (IOP), the number of antiglaucoma drugs and the incidence of adverse events were evaluated using the new Elios method (Elios Vision GmbH, Germering, Germany) for real-life data from a heterogeneous patient population undergoing ELT in combination with cataract surgery (phaco-ELT).

[Clinical approach for solid intraocular metastases].

Background: Intraocular metastases arising from solid tumors are found in approximately 2% of patients with metastatic tumor diseases and are therefore more frequent than originally assumed. They often affect the uvea and are associated with a poor prognosis. Due to the difficult diagnosis and an inconsistent treatment regimen, ophthalmologists have a special responsibility here.

In vivo evaluation of a nanotechnology-based microshunt for filtering glaucoma surgery.

To carry out the preclinical and histological evaluation of a novel nanotechnology-based microshunt for drainage glaucoma surgery. Twelve New Zealand White rabbits were implanted with a novel microshunt and followed up for 6 weeks. The new material composite consists of the silicone polydimethylsiloxane (PDMS) and tetrapodal Zinc Oxide (ZnO-T) nano-/microparticles.

Tetrapodal ZnO-Based Composite Stents for Minimally Invasive Glaucoma Surgery.

The glaucoma burden increases continuously and is estimated to affect more than 100 million people by 2040. As there is currently no cure to restore the optic nerve damage caused by glaucoma, the only controllable parameter is the intraocular pressure (IOP). In recent years, minimally invasive glaucoma surgery (MIGS) has emerged as an alternative to traditional treatments.

[Digital teaching 2020: Online teaching receives a better assessment than face-to-face teaching].

Background: Due to the corona pandemic, face-to-face teaching was no longer permitted in the summer semester 2020 and online alternatives were quickly found.

Objective: In our article, we illustrate the switch from face-to-face to online teaching in ophthalmology at the University of Lübeck and compare online teaching with face-to-face teaching.

Methods: The central teaching evaluation takes place every semester with a standardized questionnaire.

In Vitro Evaluation of Zinc Oxide Tetrapods as a New Material Component for Glaucoma Implants.

In our previous study we were able to show that zinc oxide (ZnO) tetrapods inhibit wound healing processes. Therefore, the aim of this study was to test the antiproliferative effect of two types of porous polydimethylsiloxane (PDMS)/ tetrapodal zinc oxide (ZnO-T) materials, as well as their usability for glaucoma implants. To find the best implant material, two different porous PDMS/ZnO-T materials were examined.

Zinc Oxide Tetrapods Modulate Wound Healing and Cytokine Release In Vitro-A New Antiproliferative Substance in Glaucoma Filtering Surgery.

Glaucoma filtering surgery is applied to reduce intraocular pressure (IOP) in cases of uncontrolled glaucoma. However, postoperative fibrosis reduces the long-term success of both standard trabeculectomy and microstents. The aim of this study was to test the antiproliferative and anti-inflammatory potential of ZnO-tetrapods (ZnO-T) on human Tenon's fibroblasts (HTFs) for glaucoma surgery.

[Digital teaching 2020: students assess attention during an online lecture as equivalent to a face-to-face lecture].

Background: The corona pandemic has led to short-term adjustments of the procedures in medical courses. In many departments classroom teaching was no longer possible so that it was necessary to implement digital courses to provide an adequate medical training.

Methods: We developed a digital curriculum based on the contents of our established courses using primary in-house tools, such as Cisco WebEx and Moodle.
