|a BACKGROUND AND OBJECTIVE: Evaluate depth of field (DOF) and lateral resolution (LR) on digitally assisted vitreoretinal surgery (DAVS) with different camera aperture values and TV viewing distances to determine maximal optical performance
|
| 520 |
|
|
|a PATIENTS AND METHODS: Five retinal surgeons objectively evaluated DOF and LR at low (10×), medium (15×), and high (20×) magnification on a conventional microscope (CM) and DAVS. DAVS was evaluated at different camera apertures (30%, 50%, and 75%) and TV viewing distances (1.2 meters [m], 1.5 m, and 2.0 m). A comparison between CM and optimized DAVS values was carried out
|
| 520 |
|
|
|a RESULTS: On DAVS, DOF significantly increased as camera aperture size was reduced (75% to 50%, P = .022; 75% to 30%, P ≤ .001; and 50% to 30%, P = .001) and as microscope magnification was reduced (high to medium, P = .009; high to low, P ≤ .001; and medium to low, P = .002). LR significantly increased as microscope magnification was increased (low to medium, P = .010; low to high, P ≤ .001; and medium to high, P = .015) and as TV display distance decreased (2.0 m to 1.5 m, P = .019; 2.0 m to 1.2 m, P = .009; and 1.5 m to1.2 m, P = .185). When comparing optimized DAVS against CM, DOF was significantly larger on DAVS (P = .019). LR on DAVS outperformed the CM, but statistical significant was not reached (P = .185)
|

|
|
|a CONCLUSIONS: The authors' study is the first to evaluate different aperture, magnification, and TV distance settings, and when optimized, DAVS can significantly outperform a CM with respect to DOF and LR. Optimized visual performance for DAVS is obtained with a 30% camera aperture and a TV viewing distance no further than 1.5 m. Maximal microscope magnification to exploit LR during macular surgery and low-to-medium magnification to increase DOF for overall vitrectomy surgery is recommended.
