The era of artificial intelligence and virtual reality: transforming surgical education in ophthalmology.

Training the modern ophthalmic surgeon is a challenging process. Microsurgical education can benefit from innovative methods to practice surgery in low-risk simulations, assess and refine skills in the operating room through video content analytics, and learn at a distance from experienced surgeons. Developments in emerging technologies may allow us to pursue novel forms of instruction and build on current educational models. Artificial intelligence, which has already seen numerous applications in ophthalmology, may be used to facilitate surgical tracking and evaluation. Within immersive technology, growth in the space of virtual reality head-mounted displays has created intriguing possibilities for operating room simulation and observation. Here, we explore the applications of these technologies and comment on their future in ophthalmic surgical education.

Design and Outcomes of a Novel Keratoprosthesis: Addressing Unmet Needs in End-Stage Cicatricial Corneal Blindness.

PURPOSE: The most commonly applied prosthetic devices for corneal blindness in the setting of severe cicatricial keratoconjunctivitis are the Boston keratoprosthesis type II and the modified osteo-odonto-keratoprosthesis, with these requiring either normal eyelid skin or a healthy cuspid tooth, respectively. For patients with neither attribute, we developed a new keratoprosthesis device combining positive aspects of both Boston keratoprosthesis type II and modified osteo-odonto-keratoprosthesis, which we have named the "Lux." METHODS: Short-term postoperative outcomes for the Lux keratoprosthesis, best-corrected visual acuity (BCVA), device retention, and complications, were examined in a retrospective case series of 9 eyes of 9 patients implanted at 4 centers. RESULTS: Seven of 9 (77.8%) eyes had cicatricial corneal blindness due to autoimmune disease and 2 (22.2%) from severe burns. Preoperative BCVA was ≤hand motions in all patients. Three (33.3%) had previously received at least 1 keratoprosthesis in the affected eye, and 4 (44.4%) had previously undergone ≥1 therapeutic keratoplasty. One patient had 19 previous eye surgeries. The mean duration of postoperative follow-up was 18.7 months (range 7-28 months). BCVA of ≥20/200 was achieved in all 9 patients, with 2 (22.2%) reaching 20/20 at the last examination, and all 9 (100%) of the devices were retained. One recipient developed a retinal detachment 2 months after implantation. Two (22.2%) patients required placement of a glaucoma drainage device. CONCLUSIONS: The Lux keratoprosthesis was developed for patients with severe cicatricial keratoconjunctivitis who were otherwise not candidates for existing keratoprosthesis designs. Short-term outcomes after implantation of the Lux keratoprosthesis were encouraging.

Fostering Student-Faculty Partnerships for Continuous Curricular Improvement in Undergraduate Medical Education.

PROBLEM: A number of medical schools have used curricular reform as an opportunity to formalize student involvement in medical education, but there are few published assessments of these programs. Formal evaluation of a program's acceptability and use is essential for determining its potential for sustainability and generalizability. APPROACH: Harvard Medical School's Education Representatives (Ed Reps) program was created in 2015 to launch alongside a new curriculum. The program aimed to foster partnerships between faculty and students for continuous and real-time curricular improvement. Ed Reps, course directors, and core faculty met regularly to convey bidirectional feedback to optimize the learning environment in real time. OUTCOMES: A survey to assess the program's impact was sent to students and faculty. The majority of students (202/222; 91.0%) reported Ed Reps had a positive impact on the curriculum. Among faculty, 35/37 (94.6%) reported making changes to their courses as a result of Ed Reps feedback, and 34/37 (91.9%) agreed the program had a positive impact on the learning environment. Qualitative feedback from students and faculty demonstrated a change in school culture, reflecting the primary goals of partnership and continuous quality improvement (CQI). NEXT STEPS: This student-faculty partnership demonstrated high rates of awareness, use, and satisfaction among faculty and students, suggesting its potential for local sustainability and implementation at other schools seeking to formalize student engagement in CQI. Next steps include ensuring the feedback provided is representative of the student body and identifying new areas for student CQI input as the curriculum becomes more established.

Lucia and Beyond: Development of an Affordable Keratoprosthesis.

PURPOSE: Severe corneal disease contributes significantly to the global burden of blindness. Corneal allograft surgery remains the most commonly used treatment, but does not succeed long term in every patient, and the odds of success fall with each repeated graft. The Boston keratoprosthesis type I has emerged as an alternative to repeat corneal allograft. However, cost limits its use in resource-poor settings, where most corneal blind individuals reside. METHODS: All aspects of the Boston keratoprosthesis design process were examined to determine areas of potential modification and simplification, with dual goals to reduce cost and improve the cosmetic appearance of the device in situ. RESULTS: Minor modifications in component design simplified keratoprosthesis manufacturing. Proportional machinist time could be further reduced by adopting a single axial length for aphakic eyes, and a single back plate diameter. The cosmetic appearance was improved by changing the shape of the back plate holes from round to radial, with a petaloid appearance, and by anodization of back plate titanium to impute a more natural color. CONCLUSIONS: We have developed a modified Boston keratoprosthesis type I, which we call the "Lucia." The Lucia retains the 2 piece design and ease of assembly of the predicate device, but would allow for manufacturing at a reduced cost. Its appearance should prove more acceptable to implanted patients. Successful keratoprosthesis outcomes require daily medications for the life of the patient and rigorous, frequent, postoperative care. Effective implementation of the device in resource-poor settings will require further innovations in eye care delivery.
