Medical silicone oil: a precision material for ophthalmology and minimally invasive surgery
Medical silicone oil (polydimethylsiloxane fluid) is used as a filler for retinal detachment repair in ophthalmic surgery, with a density (0.97g/cm ³) close to vitreous body, and can maintain intraocular pressure of 14-21mmHg for 6 months. In the field of digestive endoscopy, silicone oil lubricants shorten the insertion time of colonoscopes by 30% and reduce patient discomfort scores by 40%. According to statistics from a tertiary hospital, the complication rate of hysteroscopic surgery using silicone oil lubrication has decreased from 2.1% to 0.8%. Its biocompatibility has been certified by ISO 10993, and its cytotoxicity rating is 0 (non-toxic).
