“…In addition, comparing the 3D headsets used in this study, which retail for $789, with other, more expensive 3D options such as the Eyesi simulator (Haag-Streit Group, Koeniz, Switzerland), which costs $100,000 to $200,000, could help guide ophthalmic educators in choosing the best options for their program. [15][16][17][18] In conclusion, 3D technology shows promise as an educational tool in the setting of microsurgery in surgically naïve trainees. It may have a future role in cataract surgery training in formal residency education.…”

Purpose Microscopic ophthalmic surgery requires an understanding of three-dimensional (3D) spaces within the eye. Recently, there has been an increase in 3D video training tools in health care. Studies have evaluated the efficacy of 3D tutorials in general surgery, but little has been published within ophthalmology. We present a randomized study evaluating differences in surgically naïve trainees after watching either a 2D or 3D phacoemulsification tutorial. Design This was a double-blind, randomized study. A group of third and fourth year medical students at our institution were randomized with stratified randomization based on prior surgical courses to control for differences in baseline surgical skill. The two study arms were watching 2D or 3D instructional videos on phacoemulsification (Richard Mackool). Methods Participants received a preliminary survey and participated in an hour-long microscopic surgery session. During the session, participants performed tasks evaluating baseline microscopic spatial awareness and surgical skill. The students were then instructed to watch either a 2D or 3D video on phacoemulsification based on their randomized study arm. During the postintervention session, participants performed the biplanar incision and capsulorhexis steps of cataract surgery discussed in the video on model eyes. Students were evaluated on speed and overall capsulorhexis quality. Results Thirty-one students qualified for the study and completed the microscopic surgery session. Students in both groups had similar baseline speed and quality of preintervention microscopic tasks (p > 0.05 for all tasks). Postintervention, students randomized to the 3D video performed significantly faster than the 2D group for biplanar incision (11.1 ± 5.5 s vs. 20.7 ± 10.5 s, p = 0.001). There were no statistically significant differences found between the groups in capsulorhexis timing (p = 0.12) or quality score (p = 0.60). Conclusions 3D video surgical training tutorials may improve speed of certain steps of cataract surgery for surgically naïve ophthalmology trainees. Given the limited sample size of this study, further investigation of their effectiveness is warranted.

“…Using glucocorticoids either as inhaler and/or orally will increase the risk and prevalence of posterior subcapsular cataract and other ocular complications such as glaucoma [8][9][10]. Cataract treatment and care are quite expensive and constitute a financial burden, so it is crucial to prevent cataract risks in order to decrease the financial burden that cataract places on people and health authorities [11,12]. According to several studies, the Saudi population has poor knowledge regarding cataract and inadequate knowledge regarding steroid- induced cataract thus it is crucial to do further research in Saudi Arabia to elevate the level of awareness and reduce the prevalence of cataracts [13,14].…”

IntroductionThe lens, essential for vision, can be impaired by cataracts, leading to partial or complete reversible vision loss. Common risk factors include aging, diabetes, and steroid use, with significant financial implications. Limited awareness in Saudi Arabia necessitates further research to reduce cataract prevalence and increase knowledge about steroid-induced cataracts. MethodologyThis was a cross-sectional study in Al Ahsa City, Saudi Arabia that aims to assess awareness of cataracts induced by long-term steroid use. Data was collected via an online survey and analyzed using Statistical Package for Social Sciences (SPSS) version 29 (IBM Corp., Armonk, NY, USA). ResultsOur study results show that 69.8% (n=291) of participants were female, and 30.2% (n=126) were male, with the majority (62.6%, n=261) having a university education. Notably, 91.1% (n=380) reported no steroid use, while 8.9% (n=37) reported long-term use, and 10.1% (n=42) used steroids topically. There are moderate awareness levels regarding cataract and steroid associations, with 68.1% (n=284) recognizing topical steroids as the common culprits. Logistic regression highlighted the positive correlation between knowledge of cataract risks due to steroid use and actual steroid use, corroborated by a notable 73.0% (n=27) steroid usage among high-awareness individuals. ConclusionOur study underscores moderate awareness regarding steroid-related cataract risks in Al Ahsa City. Educational status significantly influenced understanding, highlighting the importance of targeted health education initiatives.

“…In the United Kingdom, ophthalmology trainees are allocated time to complete two cataract modules on an Eyesi® Surgical (VRmagic, Mannheim, Germany) simulator, a popular virtual reality ophthalmic simulator. [ 7 ] This mandatory simulation training has been found to reduce the unadjusted posterior capsule rupture rate in phaco-emulsification for novice surgeons by 38% from 2009 to 2015. [ 8 ] As a result of the COVID-19 pandemic, an increase in the use of ophthalmic simulators was observed in the UK.…”

Purpose: To establish the face and content validity of the HelpMeSee Eye Surgery Simulator – a virtual reality-based cataract surgery simulator for manual small-incision cataract surgery (MSICS). Methods: The face and content validity were assessed on the sclero-corneal tunnel construction course. A questionnaire with 11 questions focused on the visual realism, with resemblance to real life surgery, and the training value of the simulator was developed. Thirty-five experienced MSICS surgeons participated in the study. Responses were recorded using a seven-point scoring system. Results: Overall, 74.3% (26/35) of the respondents agreed that the overall visual representation of the eye and the instruments in the simulator were realistic. The task of injecting a visco-elastic through the paracentesis was reported to be the most visually realistic task with a mean score of 5.78 (SD: 1.09; range: 2–7). With regard to content validity, 77.1% (27/35) of the subjects felt agreed that the errors and complications represented throughout the entire tunnel construction module were similar to those encountered in real life; the task of entering the anterior chamber with the keratome had a mean score of 5.54 (SD: 0.98; range 1–7), being rated the highest in that aspect. Overall, 94.3% (33/35) of the subjects agreed that the simulator would be useful in developing hand–eye co-ordination. A similar number of 94.3% (33/35) agreed that based on their experience, they would recommend cataract surgical training on this simulator. Conclusion: The results suggest that the HelpMeSee Eye Surgery Simulator appears to have sufficient face and content validity for cataract surgical training.
