AI Article Synopsis
- A study in China looked into how to use 3D technology to accurately find the right size and amount of silicone oil for a special eye treatment called foldable capsular vitreous body (FCVB) surgery for people with severe retinal detachment.
- They used special software to measure the size of the eye and recommend the correct FCVB size and silicone oil volume, checking their results across five hospitals with over 250 patients.
- The results showed that the new method helps suggest the best options for doctors, and the surgery seemed to maintain similar vision after the operation compared to before it.
Article Abstract
Background: This study aimed to precisely predict the size and silicone oil injection of a foldable capsular vitreous body (FCVB) via computerized three-dimensional (3D) ocular reconstruction in the treatment of severe retinal detachment in China.
Methods: The 3D software Unigraphics NX was applied to determine the volume of the inner cavity with 16-30 mm axial length, assigning the anterior and posterior chambers, the FCVB sizes, and the silicone oil injection volume, and modeling the data between the axial length and the FCVB size. In clinical practice, IOL Master was applied to accurately measure the axial length of the contralateral healthy eye to anchor the anterior-posterior and horizontal diameters of the operated eye in horizontal position CT, and compared with the model to recommend the FCVB size and silicone oil amount, and the clinical effect was validated in cases across five hospitals in China.
Results: For the axial length of 16-30 mm, the volume of the inner cavity is 1.2 ml-8.4 ml. FCVB size and silicone oil volume were recommended based on this volume of the inner cavity. Of 253 cases, we noted 11 cases implanted with AV-10P and 1.05 ± 0.21 ml of silicone oil, 41 with AV-12P and 1.58 ± 0.18 ml of silicone oil, 163 with AV-13.5P and 2.48 ± 0.29 ml of silicone oil, 31 with AV-15P and 3.57 ± 0.39 ml of silicone oil, and 7 with AV-17P and 5.71 ± 0.81 ml of silicone oil. There was no significant difference in postoperative visual acuity scores compared with preoperative (P = 0.097), postoperative IOP(10.29 ± 0.57mmHg)was slightly higher than preoperative IOP (9.76 ± 0.48 mmHg), but there was still no statistically significant difference between the two comparisons (P = 0.405).
Conclusion: Three-dimensional reconstruction prediction is a good solution for eyeballs with obvious individualized changes in severe retinal detachment, and this method helps doctors standardize FCVB size selection and the silicone oil amount for patients.

As a global challenge, marine biofouling is causing serious economic losses and adverse ecological impacts. In recent years, a variety of promising and environmentally friendly anti-fouling strategies have emerged, among which the excellent anti-fouling performance of bionic autocrine coatings has been recognized. However, bionic autocrine coatings still suffer from uncontrollable secretion behavior, poor mechanical stability, and poor abrasion resistance.

Poly(dimethylsiloxane) (PDMS) materials have been widely researched and applied as fouling-release coatings. Incorporation of silicone oils into PDMS has been shown to improve the antifouling properties of PDMS materials. In this research, we applied sum frequency generation (SFG) vibrational spectroscopy to study PDMS materials incorporated with various silicone oils containing phenyl groups in air, water, and protein solutions.

The discharge of oil-laden wastewater from industrial processes and the frequent occurrence of oil spills pose severe threats to the ecological environment and human health. Membrane materials with special wettability have garnered attention for their ability to achieve efficient oil-water separation by leveraging the differences in wettability at the oil-water interface. These materials are characterized by their simplicity, energy efficiency, environmental friendliness, and reusability.
