Cost-effective and adaptable cataract surgery simulation with basic technology.

PURPOSE: To assess the subjective validity of a cost-effective and adaptable cataract surgery simulation technique using basic technology. METHODS: We devised and filmed a range of simulation techniques that mimic steps of phacoemulsification cataract surgery using various "everyday" basic materials. This video was combined in a "parallel" fashion with live cataract surgery so that all steps of surgery were simulated. Subsequently, we distributed an online subjective validation questionnaire on Google Forms with the embedded simulation video in a generic invitation that was forwarded via email and/or text messages/WhatsApp messenger amongst Ophthalmologists of all grades within our regions (Kent, Surrey and Sussex, London and Wales Postgraduate Deaneries). RESULTS: Face validity: 66 (99%) participants agreed that the explanations in the video were clear and 53 (79%) concurred with the realistic feel of simulated technique. Instrumentation and adaptations demonstrated were deemed user friendly and conducive to replicate by 99% participants. Content validity: 60 (90%) of participants agreed the techniques described in the video reflected the technical skills required to train cataract surgeons. Forty-nine (74%) agreed that the simulation techniques were relevant for acquiring other generic and transferable microsurgical and manual dexterity skills. CONCLUSIONS: We demonstrated subjective validity of our cost-effective cataract simulation technique. Our model can be used as an adjunct to intraocular and virtual reality training for cataract surgery by removing the barrier of cost and improved exposure to real instruments used in cataract surgery.

A study of the role and educational needs of ophthalmic specialist nurses.

AIMS: To explore the current roles, responsibilities and educational needs of ophthalmic specialist nurses (OSNs) in the UK. METHOD: A survey of 73 OSNs ranging from band 4 to band 8 was undertaken in May 2018. FINDINGS: 73% of OSNs undertake more than one active role, with 59% involved in nurse-led clinics; 63% felt formal learning resources were limited, with 63% reporting training opportunities and 21% reporting time as major barriers to further training. More than 38% emphasised hands-on clinic-based teaching had a greater impact on their educational needs. Some 64% were assessed on their skills annually and 59% felt confident with their skill set. CONCLUSION: The Ophthalmic Common Clinical Competency Framework provides a curriculum and assessment tools for OSNs to use as a structure to maintain clinical skills and knowledge. Eye departments should use this as guidance to target learning needs and improve standards of care to meet the changing needs of society.

Personal Protective Equipment (PPE) use among emergency eye care professionals in the UK during the COVID19 pandemic.

EEC staff were provided with rapidly changing personal PPE guidance by Public Health England (PHE) with specific subspecialty advice from the British Emergency Eye Care Society (BEECS) and the Royal College of Ophthalmologists (RCOphth) UK during the COVID19 pandemic. BEECS undertook a baseline survey of its members after the initial response from the RCOphth 16/3/20 mirroring Public Health England (PHE) advice and a follow- up survey after the guidance was updated on 9/4/20. A combined total of 84 responses were received. Improvements after RCOphth changes between the two surveys from hospital respondents showed increases in temperature screening (13%), scrub use (34%), use of aprons (31%), masks (4%), eye protection (35%), gloves (25%) and slit lamp guard (1%). Our findings demonstrate a positive and significant adaptation of PPE in response to change in guidance published by PHE, RCOphth and BEECS between 16/3/20 and 11/4/20. The COVID19 pandemic has rapidly taken over the normal activity of Ophthalmic departments creating unprecedented challenges. Following initial confusion and vulnerability expressed by EEC professionals to PPE guidance, most Trusts appear to have adapted and are doing similar things. The response has been swift and effective as a result of good team work and early advice from BEECS and the RCOphth. On the whole, management teams are listening.

Outcomes of Nd: YAG Goniopuncture After Viscocanalostomy/Phacoviscocanalostomy.

PURPOSE: The aim of this study is to evaluate the safety and efficacy of laser goniopuncture (LGP) to lower intraocular pressure (IOP) post-viscocanalostomy (VC)/phacoviscocanalostomy (PVC). Outcomes include: IOP reduction from pre-LGP levels and the need for further topical antiglaucomatous medication or surgery. PATIENTS AND METHODS: A total of 541 eyes that underwent VC/PVC between 2009 and 2012, at the Stanley eye unit in Abergele were included in the study. INCLUSION CRITERIA: All patients who had LGP at any timepoint after VC/PVC when target IOP was not achieved +/- progression in visual field with at least 6 months of follow-up data.Statistical analysis was performed on IOP values pre- and post-LGP, involving χ, Fischer exact, Mann-Whitney U, and Wilcoxon tests. A P-value of <0.05 was accepted as the level of significance. RESULTS: Of the 515 included eyes, 136 (26%) required LGP after a mean of 15.11±9.73 months after surgery (95% confidence interval, 13.46-16.76 mo), ranging from 1 to 42 months. LGP reduced IOP significantly from a mean of 22.92±5.80 to 17.08±5.30 mm Hg immediately for all eyes, a reduction of 5.84 mm Hg (or a 25% reduction) (P<0.0001). IOP significantly reduced in the VC group with a mean reduction of 7.60 mm Hg compared with 4.85 mm Hg in the PVC group immediately after the procedure (P=0.0038). LGP was required sooner in the VC group compared with PVC, 11.35 and 14.57 months, respectively (P=0.0393). A total of 69 (62%) eyes were commenced on topical IOP-lowering medications, mean 7.26±6.41 months after LGP. CONCLUSIONS: This study supports previous evidence that LGP enhances the IOP-lowering success of VC/PVC. The advantages of LGP are that it is a minimally invasive clinic-based procedure with a low complication rate.

Rituximab in refractory ophthalmic Wegener's granulomatosis: PR3 titers may predict relapse, but repeat treatment can be effective.

OBJECTIVE: To report the long-term outcome of the treatment of refractory ophthalmic Wegener's granulomatosis (WG) with rituximab (RIT), including rates of relapse, predictors of relapse, and results of repeat treatment. DESIGN: Retrospective case series. PARTICIPANTS: We included 20 consecutive patients with refractory ophthalmic WG treated with RIT. INTERVENTION: Intravenous RIT infusion, 2 doses of 1 g given 2 weeks apart. MAIN OUTCOME MEASURES: Regular clinical, serologic, and immunologic examinations for disease activity and extent, and for treatment-related side effects. RESULTS: All 20 patients entered remission, the median time to remission being 2 months (range, 1-6). Seven patients (35%) relapsed at a median of 13 months (range, 9-18). Five of these patients took a second course of RIT, and all achieved remission without further relapse. In the 16 patients with positive anti-proteinase-3 (PR3) titers at baseline, rising anti-PR3 titer was a statistically significant predictor of relapse. There were 4 severe adverse events during the study, of which one was directly attributed to treatment with RIT. CONCLUSIONS: In this series of 20 patients with refractory ophthalmic WG, RIT was effective in inducing remission. Relapse occurred in one third of patients within 18 months and seemed to be predictable by rising anti-PR3 titers, but retreatment with RIT was effective in this group. In patients with ophthalmic WG, RIT may be capable of inducing extended remission, in contrast with other biologic and conventional treatments in common use.
