Abstract
Purpose The purpose of this study was to develop and validate RetinaVR, an affordable, portable, and fully immersive virtual reality (VR) simulator for vitreoretinal surgery training. Methods We built RetinaVR as a standalone app on the Meta Quest 2 VR headset. It simulates core vitrectomy, peripheral shaving, membrane peeling, and endolaser application. In a validation study (n = 20 novices and experts), we measured: efficiency, safety, and module-specific performance. We first explored unadjusted performance differences through an effect size analysis. Then, a linear mixed-effects model was used to isolate the impact of age, sex, expertise, and experimental run on performance. Results Experts were significantly safer in membrane peeling but not when controlling for other factors. Experts were significantly better in core vitrectomy, even when controlling for other factors (P = 0.014). Heatmap analysis of endolaser applications showed more consistent retinopexy among experts. Age had no impact on performance, but male subjects were faster in peripheral shaving (P = 0.036) and membrane peeling (P = 0.004). A learning curve was demonstrated with improving efficiency at each experimental run for all modules. Repetition also led to improved safety during membrane peeling (P = 0.003), and better task-specific performance during core vitrectomy (P = 0.038), peripheral shaving (P = 0.011), and endolaser application (P = 0.043). User experience was favorable to excellent in all spheres. Conclusions RetinaVR demonstrates potential as an affordable, portable training tool for vitreoretinal surgery. Its construct validity is established, showing varying performance in a way that correlates with experimental runs, age, sex, and level of expertise. Translational Relevance Fully immersive VR technology could revolutionize surgical training, making it more accessible, especially in developing nations.

[PMID: 38055121 PMCID: PMC10776525 DOI: 10.1007/s40123-023-00843-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 10/20/2023] [Indexed: 12/07/2023] Open
Abstract
The port delivery system (PDS) of anti-VEGF therapy provides continuous delivery of ranibizumab (RBZ). In October of 2021, the American Food and Drug Administration (FDA) approved the PDS with RBZ as a treatment option for neovascular age-related macular degeneration (nAMD). As the field of PDS with RBZ is progressing rapidly, this narrative review provides a much-needed overview of existing clinical trials as well as ongoing and upcoming trials investigating PDS with RBZ. The phase 2 LADDER trial reported that the mean time to first refill with RBZ PDS 100 mg/ml was 15.8 months (80% CI 12.1-20.6), and pharmacokinetic profiling revealed a sustained concentration of RBZ in serum and aqueous humor. Later, the phase 3 ARCHWAY trial reported that PDS with RBZ (100 mg/ml) refilled every 24 weeks was non-inferior to monthly intravitreal injection (IVI) with RBZ (0.5 mg) in patients with nAMD over 9 months and 2 years. However, patients with PDS had a higher rate of adverse events including vitreous hemorrhage and endophthalmitis. Patients indicate high treatment satisfaction with both PDS and IVI, but the lower number of treatments with PDS was reported as a preferred choice. Several ongoing and future clinical trials, of which details are discussed in this paper, are further exploring the potentials of PDS with RBZ. We conclude that the PDS provides continuous deliverance of RBZ and that clinical efficacy levels are non-inferior to IVI therapy for nAMD. Yet, a higher rate of adverse events remains a concerning detail for widespread implementation. Future studies are warranted to better understand which patients may benefit best from this treatment approach, if long-term efficacy can be sustained, and if safety of PDS can be further improved.

Harmonizing ophthalmic residency surgical training across Europe: A proposed surgical curriculum. Eye (Lond) 2023; 37:3256-3262. [PMID: 36932160 PMCID: PMC10564786 DOI: 10.1038/s41433-023-02502-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 01/29/2023] [Accepted: 03/08/2023] [Indexed: 03/19/2023] Open
Abstract
BACKGROUND One of the core aims of the European Union of Medical Specialists is to harmonize training across Europe by creating European Training Requirements for all medical specialties including Ophthalmology. The theoretical part is already defined by the EBO, however as ophthalmology also includes surgical skills, we herein propose a surgical minimum curriculum for ophthalmology residents in Europe. METHODS National and international ophthalmic training curricula which are publicly available in English were reviewed and compared. The final proposal was created from 5 criteria: 1. Disease prevalence; 2. Patient safety; 3. Case-trainee ratio; 4. Skill transfer; and 5. Technical difficulty. RESULTS In total 7 different training curricula from across the world were compared. Among the surgical procedures, cataract surgery has the highest median number of procedures required to be completed during residency: 86 procedures (50-350). Followed by oculoplastics: 28 procedures (10-40) and panretinal photocoagulation: 27.5 procedures (10-49) Full procedural competence is proposed in 9 surgical skills, including YAG laser posterior capsulotomy, retinal argon laser, intravitreal injection, corneal foreign body removal, removal of corneal sutures, facial and periocular laceration repair, eyelid laceration repair, minor eyelid procedures, and punctal occlusion. These procedures are deemed essential and feasible for all ophthalmology residents in Europe to perform independently upon completion of their training. CONCLUSION This proposal should be regarded as a recommendation based on comparable surgical curricula in use worldwide to establish standards across European countries and may serve as valuable insight to those responsible for compiling ETRs for ophthalmology, or their national curriculums.

Abstract
PURPOSE To establish a workflow to visualize the surgical anatomy in 3D based on histological data of eyes of experimental animals for improving the planning of complex surgical procedures. METHODS Four C57BL/6J wild-type(wt) mouse eyes, three Brown Norway rat eyes and four Chinchilla Bastard rabbit eyes were enucleated and processed for standard histology with serial sections and hematoxylin and eosin staining. Image stacks were processed to obtain a representation of the eye anatomy in 3D. In addition, virtual image stacks and 3D point clouds were generated by processing sagittal sections of eyes with stepwise 180° rotation and projection around the eye axis to construct a rotationally symmetric 3D model from one single sagittal section. RESULTS Serial sections of whole eyes of mice, rats and rabbits showed significant artifacts interfering with a practical image stack generation and straightforward 3D reconstruction despite the application of image registration techniques. A workflow was established to obtain a 3D image of the eye based on virtual image stacks and point cloud generation by rotation of a single sagittal section of the eye around the symmetry axis. By analyzing the tissue shrinkage during histological processing true biometric reconstructions of the eyes were feasible making the resulting model usable for 3D modeling and simulation, e.g. for planning of complex surgical procedures in different species. CONCLUSION Because serial sections of the eye with standard histological protocols yielded too many artifacts for a straightforward 3D visualization we reconstructed a pseudorealistic 3D model based on virtual image stacks and point cloud generation calculated from a single sagittal section of the eye. Such a model detailing microscopic structures of the whole eye will allow for a specific planning of surgical procedures in small animal eyes in order to prevent surgical complications in a very early stage of an experiment and it will support the design and development of complex intraocular implants. It will therefore be helpful in surgical teaching and improve laboratory animal welfare by an expected reduction of experimental animal numbers. Further processing including integration of mechanical tissue properties is needed to convert these 3D models into a practical virtual reality teaching and simulation platform for eyes of several species.

Indian J Ophthalmol 2023; 71:3064-3068. [PMID: 37530282 PMCID: PMC10538810 DOI: 10.4103/ijo.ijo_381_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2023] [Revised: 06/08/2023] [Accepted: 06/13/2023] [Indexed: 08/03/2023] Open
Abstract
Purpose To profile vitreoretinal (VR) fellows-in-training from India exposed to the Eyesi surgical simulator, to identify potential barriers to voluntary use, and enumerate the most preferred tools and tasks before incorporating them into a formal skill-transfer curriculum. Methods A questionnaire consisting of 22 questions was designed and circulated through an online portal (surveymonkey.com) to four different institutes of India having a VR surgical fellowship program and using a functional Eyesi (Haag-Streit) simulator. All fellows and trainees who were exposed to the simulator were eligible to participate, irrespective of time spent on the simulator and exposure to training steps on real patients. The responses collected were private and anonymous. Results Of the 37 respondents, most (n = 25, 68%) considered surgical simulators to be the best training tool before operating on the human eye. A majority (n = 35, 94.5%) of participants spent <3 h per week on the simulator, which, most (n = 30, 81%) felt was not enough time. The main reasons for this underutilization were work-hour limitations (54.8%), lack of a structured training program (19.3%), or a dedicated supervisor (16.1%). Again, the majority (n = 33, 89%) of participants responded that VR surgical skills acquired during simulator training were transferrable to the operating room, which was reflected by their response (n = 31, 83.7%) that simulator-based training should be made mandatory before operating room exposure. Conclusion This study gives an insight into the overall practice patterns and preferences in simulation training of surgical VR fellows-in-training across India. It indicates that the simulator is extremely helpful to fellows and if adopted, VR surgical simulators with organized, directed, and supervised sessions will considerably improve the surgical training experience.

[PMID: 36001249 DOI: 10.1007/s40123-022-00559-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Accepted: 08/03/2022] [Indexed: 11/29/2022] Open
Abstract
INTRODUCTION With no specific overview on simulation-based training for educational purposes among residents in ophthalmology, this narrative review attempts to highlight the current literature on modern educational simulation-based tools used to educate residents in ophthalmology. METHODS We searched databases Web of Science and PubMed between March 15 and July 21, 2022. Relevant and accessible articles and abstracts published after 2006 and in English only were included. RESULTS Simulation-based cataract surgery is associated with better outcomes in the operating room and faster surgeries. Construct validity has been established across different procedures and levels in simulation-based cataract surgery and simulation-based vitreoretinal surgery. Other simulation-based procedures indicate promising results but in general lack evidence-based validity. DISCUSSION This narrative review highlights and evaluates the current and relevant literature of modern educational simulation-based tools to train ophthalmology residents in different fundamental skills like simulation-based ophthalmoscopy and complex surgical procedures like simulation-based cataract surgery and vitreoretinal surgery. Some studies attempt to develop simulators for the use in education of ophthalmology residents. Other studies strive to establish validity of the respective procedures or modern education tools and some studies investigate the effect of simulation-based training. The most validated modern educational simulation-based tool is the Eyesi Surgical Simulator (VRmagic, Germany). However, other modern educational simulation-based tools have also been evaluated, including the HelpMeSee Eye Surgery Simulator (HelpMeSee Inc., New York, USA) and the MicroVisTouch Surgical Simulator (ImmersiveTouch, USA). CONCLUSION Simulation-based training has already been established for residents in ophthalmology to benefit the most from skill-demanding procedures resulting in better learning and better patient handling. Future studies should aim to validate more simulation-based procedures for the teaching of ophthalmology residents so that the evidence is kept at a high standard.

Abstract
In the last two decades there has been an enormous growth in the use of clinical simulation. This teaching-learning methodology is currently the main tool used in the training of healthcare professionals. Clinical simulation is in tune with new paradigms in education and is consistent with educational theories that support the use of experiential learning. It promotes the development of psychomotor skills and strengthens executive functions. This pedagogical approach can be applied in many healthcare topics and is particularly relevant in the context of restricted access to clinical settings. This is particularly relevant considering the current crisis caused by the COVID-19 pandemic, or when trying to reduce the frequency of accidents attributed to errors in clinical practice. This mini-review provides an overview of the current literature on healthcare simulation methods, as well as prospects for education and public health benefits. A literature search was conducted in order to find the most current trends and state of the art in medical education simulation. Presently, there are many areas of application for this methodology and new areas are constantly being explored. It is concluded that medical education simulation has a solid theoretical basis and wide application in the training of health professionals at present. In addition, it is consolidated as an unavoidable methodology both in undergraduate curricula and in continuing medical education. A promising scenario for medical education simulation is envisaged in the future, hand in hand with the development of technological advances.

Abstract
Abstract
Objective The objective of our paper is to review all of the relevant literature in ophthalmology microsurgical education and identify which teaching methodologies were most effective.
Methods A systematic review and meta-analysis of the literature was conducted. Electronic databases, including Ovid MEDLINE, Cochrane CENTRAL, and EMBASE, were searched with preset terms. The search was through December 11, 2019. Eligibility criteria included studies with sufficient data for analyzing associations between surgical teaching techniques and success rates in surgical skills and the organization of the intervention as a microsurgical skills course, curriculum, or program. The articles were independently reviewed by two authors. Each included study was evaluated for quality using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach and risk of bias using the Cochrane Collaboration's tool for assessing bias.
Data Extraction and Synthesis Data extraction was performed by two reviewers and disagreements were checked by a third reviewer. A random-effects analysis was used to pool the outcomes of studies.
Main Outcomes and Measures Outcomes included time for completion of surgical task, level of preparedness, competency score, and number of surgeries with complications.
Results A total of 439 studies were reviewed and 13 studies (n = 8,790 surgical cases; n = 115 trainees) were included in the meta-analysis. Excluded articles studied cataract simulation training as the primary intervention or were not related to ophthalmology. All pooled results demonstrated a positive association with surgical outcomes; however, video-based education (standardized mean difference [SMD] = 2.49 [95% confidence interval (CI): 0.36–4.63]; four effects [four studies]; n = 69; I
2 = 90%) and stepwise teaching method (odds ratio [OR = 3.84 [95% CI: 2.66–5.55]; six effects [six studies]; n = 6,968; I
2 = 39%) interventions were the most favorable.
Conclusion and Relevance The following five interventions evaluated in this paper were found to be effective methods of improving performance outcomes in ophthalmic microsurgery: (1) didactic lectures, (2) video-based education, (3) surgical wet-laboratory, (4) stepwise method, and (5) direct supervision and feedback. Our meta-analysis concludes that video-based education and stepwise teaching interventions are the most effective methods for a microsurgical ophthalmology training curriculum. Combining the strengths of the interventions analyzed in this study should be considered when implementing and adjusting ophthalmic surgical skills curriculums.

Abstract
PURPOSE To investigate whether pretraining of basic skills in virtual vitreoretinal surgery affected the performance curve when proceeding to procedure-specific modules. METHODS This study was a prospective, randomized, controlled, two-centre study. Medical students were randomized into two groups: Group 1 pretrained basic psycho-motor skills (Navigation Training level 2 and Bimanual Training level 3) until they reached their performance curve plateau. Hereafter, both groups trained on the procedure-specific modules (Posterior Hyaloid level 3 and ILM Peeling level 3) until they reached their performance curve plateau. Plateau was defined as three consecutive sessions with the same score with an acceptable variation. The primary outcome was time used to reach performance curve plateau in the procedure-specific modules. RESULTS A total of 68 medical students were included, and equally randomized into two groups. The participants in Group 1 used a median time of 88 minutes to reach plateau in the basic skills modules but did not differ from Group 2 in time to reach plateau on the procedure-specific modules (183 min versus 210 min, p = 0.40) or in the amplitude of plateau. Group 1 and 2 differed significantly in the starting score of ILM peeling level 3 (0 (0-0) versus 3.5 (0-75), p = 0.03). CONCLUSION We were not able to show positive skill transfer from basic skills training to the procedure-specific modules in time, starting score or amplitude of plateau. Thus, we recommend that aspiring vitreoretinal surgeons proceed directly to simulation-based training of procedures instead of spending valuable training time on basic skills training.

Abstract
PURPOSE To develop and investigate an evidence-based performance test for assessment of vitreoretinal surgical skills on the EyeSi Surgical Simulator. METHODS Ten junior residents without any surgical experience, eight senior residents with prior experience in cataract surgery and five vitreoretinal surgeons were included in the study. The test consisted of seven modules and was completed twice by all groups during a single session. Validity evidence was evaluated using Messick's validity framework. Senior residents completed four additional test sessions and were retested 3 months after to assess skill acquisition and retention. RESULTS Content was aligned with vitreoretinal surgical skills as evaluated by expert surgeons. Response process was ensured through standardized instruction and data collection. The test showed satisfactory internal consistency with Cronbach's α = 0.76 (internal structure) and significant discriminative ability between the residents and the experienced surgeons (relation to other variables). A pass/fail level was determined at 596 using the contrasting groups' method. Consequences of applying this standard resulted in no false positive and no false negative. Senior residents significantly improved their simulator skills over time, reaching a plateau at the fifth iteration and equalling expert performance (p = 0.420). This level of competency was retained during the post-3-month retention testing (p = 0.062). CONCLUSION We established a performance test with solid evidence for assessment of vitreoretinal surgical skills on the EyeSi Simulator and determined a benchmark criterion that may be used for future implementation of proficiency-based training for novices.

Abstract
PURPOSE Most published systematic reviews have focused on the use of virtual reality (VR)/augmented reality (AR) technology in ophthalmology as it relates to surgical training. To date, this is the first review that investigates the current state of VR/AR technology applied more broadly to the entire field of ophthalmology. METHODS PubMed, Embase, and CINAHL databases were searched systematically from January 2014 through December 1, 2020. Studies that discussed VR and/or AR as it relates to the field of ophthalmology and provided information on the technology used were considered. Abstracts, non-peer-reviewed literature, review articles, studies that reported only qualitative data, and studies without English translations were excluded. RESULTS A total of 77 studies were included in this review. Of these, 28 evaluated the use of VR/AR in ophthalmic surgical training/assessment and guidance, 7 in clinical training, 23 in diagnosis/screening, and 19 in treatment/therapy. 15 studies used AR, 61 used VR, and 1 used both. Most studies focused on the validity and usability of novel technologies. CONCLUSIONS Ophthalmology is a field of medicine that is well suited for the use of VR/AR. However, further longitudinal studies examining the practical feasibility, efficacy, and safety of such novel technologies, the cost-effectiveness, and medical/legal considerations are still needed. We believe that time will indeed foster further technological advances and lead to widespread use of VR/AR in routine ophthalmic practice.

Mapping the intellectual structure of research on surgery with mixed reality: Bibliometric network analysis (2000-2019). J Biomed Inform 2020; 109:103516. [PMID: 32736125 DOI: 10.1016/j.jbi.2020.103516] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 06/16/2020] [Accepted: 07/17/2020] [Indexed: 12/27/2022]
Abstract
OBJECTIVE The purpose of this study is to view research trends on surgery with mixed reality, and present the intellectual structure using bibliometric network analysis for the period 2000-2019. METHODS Analyses are implemented in the following four steps: (1) literature dataset acquisition from article database (Web of Science, Scopus, PubMed, and IEEE digital library), (2) dataset pre-processing and refinement, (3) network construction and visualization, and (4) analysis and interpretation. Descriptive analysis, bibliometric network analysis, and in-depth qualitative analysis were conducted. RESULTS The 14,591 keywords of 5897 abstracts data were ultimately used to ascertain the intellectual structure of research on surgery with mixed reality. The dynamics of the evolution of keywords in the structure throughout the four periods is summarized with four aspects: (a) maintaining a predominant utilization tool for training, (b) widening clinical application area, (c) reallocating the continuum of mixed reality, and (d) steering advanced imaging and simulation technology. CONCLUSIONS The results of this study can provide valuable insights into technology adoption and research trends of mixed reality in surgery. These findings can help clinicians to overview prospective medical research on surgery using mixed reality. Hospitals can also understand the periodical maturity of technology of mixed reality in surgery, and, therefore, these findings can suggest an academic landscape to make a decision in adopting new technologies in surgery.

Abstract
PURPOSE OF REVIEW To review the cardiac surgical simulation experience with a focus on data supporting its use. RECENT FINDINGS Simulators have been used to improve trainee performance across multiple surgical domains. Few cardiac surgery residency programs have incorporated the use of simulation individually and Boot Camp programs in the United States and Canada have also introduced surgical simulation early in cardiac surgical training. Simulation curricula have some common elements: component tasks, deliberate practice, progressive operative responsibility, and coaching by an experienced surgeon. Cardiac surgical simulators can range from inexpensive, low-fidelity models for the practice of isolated skills to high-fidelity, operating room-scenarios. Multiple small studies have consistently demonstrated that the use of simulation improves qualitative and quantitative performance measures as well as overall resident confidence in clinical settings. To our knowledge, no study has demonstrated that use of simulation has led to improved quantitative performance measures in the operating room or patient outcomes. The barriers to wider use of surgical simulators include perceived lack of time and resources, the need for sustained practice and the lack of high-quality data to demonstrate clinical benefit. SUMMARY Incorporation of cardiac surgery simulation has been slow in most residency programs. There is consistent data demonstrating that simulation improves resident performance measures of simulation-based tasks but whether this will lead to improved patient outcomes remains an open question.
