“…Some respondents felt they would rather practice on human cadaveric eyes while others thought practicing on the artificial eyes was too expensive and the models should only be used for final surgical assessments of trainees. This statement should be taken in context of the fact that SimulEYE Iris Suturing & IOL model cost ~ US $50 while a human cadaveric eye is estimated at US $500 per research globe (11,12). In fact, one might argue that utilizing these eye models may be much more cost effective, especially for government funded ophthalmology residency programs.…”

“…to surgical simulators or cadaveric eyes (13,14). Moreover, these artificial eye models become even more attractive when considering their longevity, safety, reproducibility, ease of storage and limited ethical concerns (11,(15)(16)(17). Additionally, when compared to cadaveric eyes, these models do not require keratoprosthesis to visualize the anterior chamber and they are much simpler to setup (17)(18)(19).…”

To evaluate the face and content validity of the use of artificial eye models (SimulEYE Iris Suturing & IOL model, InsEYEt, Westlake Village, CA) in training physicians the techniques required for secondary intraocular lens (IOL) fixation. Secondary IOL fixation, or secondary IOL implantation, is a common yet technically challenging skill useful in the treatment of primary IOL implantation failure, zonular instability, or aphakia related to trauma or surgery. Materials and Methods:Twenty-eight ophthalmologists at the 2019 Canadian Ophthalmology Society annual meeting underwent a secondary IOL fixation wet-lab using artificial eye models. The technique was scleral suturing of a single piece IOL with via 4 closed-loop haptics. All of the ophthalmologists were given an 18-response survey immediately following the training session which were composed of statements which addressed the face and content validity of the artificial eyes. Responses were recorded on a 5-point Likert-type scale ranging from (5) strongly agree to (1) strongly disagree. Mann-Whitney U analysis compared instructor versus non-instructor and expert versus non-expert respondent responses. Results: Respondents rated all statements regarding the model with a median response of 3 (Neither Agree or Disagree) to 5 (Strongly Agree). Mann-Whitney U analysis did not show a significant difference in responses for expert versus non-expert and instructor vs non-instructor respondents for any of the survey statements.The artificial eye received highest ratings for its usefulness for training residents, ease of set-up and clean-up compared to cadaveric models and how using the model is a better way to learn the procedure than discussion or observation and will likely result in future surgical success. The lowest survey ratings were for the model's realism when compared to human cadaveric models. Conclusions:The artificial eye model was generally regarded highly by ophthalmologists with all levels of experience performing secondary IOL fixation. These results suggest that this artificial eye may be a valuable tool for teaching secondary IOL fixation in competency-based ophthalmology education programs.

“…16 As a result, artificial eye models have risen in popularity as training tools for ophthalmologists and residents. [17][18][19][20] This study analyzes the feasibility of an artificial eye model, the Bioniko Okulo BR8 as an alternative training tool to cadaveric specimens for secondary IOL fixation via Yamane technique. Valued at $200 USD, the Bioniko Okulo BR8 is designed for simulation of cataract surgery and its associated complications.…”

To assess the face and content validity of an artificial eye model for secondary intraocular lens (IOL) fixation via the Yamane technique. Methods: Ophthalmologists and residents participated in a 90-minute simulation session on secondary IOL fixation via the Yamane technique. Hands-on practice of this technique was performed on an artificial eye, the Bioniko Okulo BR8. After, all ophthalmologists answered an 18-question survey assessing the face and content validity of the model. Survey responses were recorded on a 5-point double-headed Likert scale, ranging from strongly agree (1)-to-strongly disagree (5) (Figure 1). Results: Twenty-three surveys were completed. Respondents rated the survey with a median response of 1 (strongly agree)-to-3 (neutral). Highest ratings for the model were received for "usefulness for training residents", and "easier to set up and clean-up compared to a cadaver". Lowest ratings were received for realism of the model compared to cadaveric eyes. Statistical analysis revealed no significant difference among identified groups. Ratings for face and content validity were viewed favorably, both with an overall median response of 2.00 (agree). Conclusion:The Bioniko Okulo BR8 shows promise as a valid tool for practicing secondary IOL fixation via the Yamane technique. Considering recent guidelines in competency-based ophthalmology education programs, this model may be a valuable tool over traditional techniques for teaching and improving surgical skill amongst trainees.
