Objective This paper describes a new type of silicone-oil-based Fe3O4 magnetic liquid and discusses the feasibility of vitreous implants from the mechanics viewpoint.Methods This was an experimental study.The silicone-oil-based Fe3O4 magnetic liquid had been studied previously in the pig eye cavity.The experimental results demonstrated that the silicone-oil-based Fe3O4 magnetic liquid moves on the cavity surface and aggregates at some position under the action of the magnetic field force.The silicone-oil-based Fe3O4 magnetic liquid was filled into a simulated eyeball that was suspended in a gradient magnetic field.The force applied on the simulated eyeball was measured.Results The silicone-oil-based Fe3O4 magnetic liquid moved on the simulated eye cavity surface and aggregated along the magnetic field line with an applied pressure of about 17 mmHg.Conclusion The silicone-oil-based Fe3O4 magnetic liquid approximates the vitreous implant requirements,and has unique mobile and location advantages.This provides a preliminary study approach and an estimate of usefulness for magnetic liquid used in retinal repair.
