A recent publication in the Indian Journal of Ophthalmology described a prospective observational study of 313 eyes assessing the surgical efficacy of a three-dimensional (3D) visualization system (NGENUITY® 3D Visualization System) as compared to the conventional microscope in various anterior segment and scleral buckle procedures performed by four surgeons with at least 5 years of surgical experience.†
Cases were divided into 3 groups: Conventional Microscope group (Group I); learning cases in the NGENUITY group (Group IIA); post-learning cases in the NGENUITY group (Group IIB); Group IIA cases comprised 15-30% of Group II cases depending on the complexity level of case types.†
Patient demographics, diagnosis, surgical procedure and case time, intraoperative and early post-operative complications were noted. Using a questionnaire, ease of each surgical step, surgeon comfort, and resident and scrub nurse educational value using a 5‑point scale score were noted for each case.†
- Mean surgery duration for phacoemulsion + IOL implant, Trabeculectomy and glaucoma triple procedure was not significantly different when comparing the Conventional Microscope group (Group I) to the post-learning 3D group (Group IIB), but was significantly higher when compared to the 3D learning group (Group IIA).†
- Likewise, no significant difference in 5‑point scale scores were noted between the Conventional Microscope group (Group I) and the post-learning 3D visualization group (Group IIB), but there were significant differences when compared to the learning-phase 3D visualization group (Group IIA).†
- Time lag, poor color contrast, and field of view issues were apparent only during the learning stage in the 3D visualization group (Group IIA).†
- Image resolution, depth perception, illumination, postural comfort and educational relevance was graded higher for 3D surgery.†
Equivalent complication rate and no need to convert back to the microscope demonstrated the safety and non‑inferiority of 3D visualization.†
Dividing the cases in the 3D visualization group into learning phase and post-learning phase assisted in more closely highlighting the potential benefits of 3D visualization-assisted anterior segment ophthalmic surgery.†
