Tactile Feedback in Cataract and Retinal Surgery: A Survey-Based Study

Huynh N, Akbari M, and Loewenstein JI


Purpose: To evaluate the perceived importance of tactile feedback and visualization in performing surgery among cataract and vitreoretinal surgeons using an online survey. Methods: A nine-question, survey-based questionnaire was developed and sent to members of the Retina Society, American Academy of Ophthalmology, and New England Ophthalmological Society. Participants were asked to rate the importance of tactile feedback and visualization in cataract and retinal surgery. Results: On a rating scale of 1 to 5, with 5 being most important, visualization was rated with an average score of 4.97 + 0.24 and 4.94 + 0.39 among cataract and vitreoretinal surgeons, respectively. For tactile feedback, the average ratings by cataract and vitreoretinal surgeons were 3.72 + 1.05 and 3.26 + 1.36, respectively. There was a statistically significant difference (P=0.03) with respect to tactile feedback between cataract and retinal surgeons. Conclusions: Tactile feedback appears to play an important role in cataract and retinal surgery. Integration of haptic interfaces to existing virtual simulators may provide a more realistic operative experience.
