Purpose: To evaluate a 3-D visualization helmet (3DVH) during 23-gauge pars plana vitrectomy (PPV) for macular holes (MH) and macular puckers (MP).
Methods: A total of 184 eyes of 184 patients undergoing PPV for MH or MP were randomly selected for surgery with 3DVH or standard Galilean microscope (GM). Only one highly trained surgeon performed each PPV. A surgical comfort score, ranging from 1 to 10 was recorded after each operation. Statistical analysis was run with SPSS to compare parameters before and after surgery and between the two groups.
Results: No statistical differences were found between the two groups for mean best correct visual acuity improvement after surgery (p < 0.001). Mean surgery comfort evaluation was 7.63 ± 0.48 in 3DVH eyes and 8.21 ± 0.62 in GM ones (p = 0.09); mean overall surgical time was 35.12 ± 3.8 min in 3DVH eyes and 32.7 ± 2.27 min in GM ones (p < 0.001); mean peeling time was 14.24 ± 3.42 min in 3DVH eyes and 13.61 ± 4.63 min in GM ones (p = 0.11).
Conclusions: According to the data observed in this study, the 3DVH provides adequate safety and efficacy in retinal and macular visualization during PPV for MH and MP.

Cellulose microgel beads fabricated using the dropping technique suffer from structural irregularity and mechanical variability. This limits their translation to biomedical applications that are sensitive to variations in material properties. Ionic salts are often uncontrolled by-products of this technique, despite the known effects of ionic salts on cellulose assembly.

: Recent advances in intraoperative navigation systems have improved the accuracy of pedicle screw placement in spine surgery. However, many hospitals have limited access to these advanced technologies due to resource constraints. In such settings, postoperative computed tomography (CT) evaluation remains crucial for assessing screw placement and related potential complications.

Multidimensional 3D-rendered objects are an important component of vision research and video-gaming applications, but it has remained challenging to parametrically control and efficiently generate those objects. Here, we describe a toolbox for controlling and efficiently generating 3D rendered objects composed of ten separate visual feature dimensions that can be fine-adjusted using python scripts. The toolbox defines objects as multi-dimensional feature vectors with primary dimensions (object body related features), secondary dimensions (head related features) and accessory dimensions (including arms, ears, or beaks).

Purpose: To evaluate the outcomes of scleral-fixated intraocular lenses (IOLs) implanted using either Yamane technique or Gore-Tex suture fixation, in comparison to intracapsular lens fixation, and to assess the efficacy of various lens formulas in achieving predicted refractive targets.
Patients And Methods: This study included 45 eyes from 44 patients with scleral-fixated IOLs, comprising 37 Yamane eyes and 8 Gore-Tex eyes. Preoperative refractive predictions from various formulae were compared with final postoperative refraction.
