摘      要：Objective:To study the characteristics of the intraocular lens using ion beam sputtering depositing titanium nitride thin film on the intraocular lens(IOLs).Methods:To deposite titanium nitride thin film on the top of intraocular lens by ion beam sputtering *** analyzed the surface morphology of intraocular lens through SEM and *** detected intraocular lens resolution through the measurement of intraocular *** of intraocular lens is preliminary evaluated in this ***:The surface morphology of intraocular lens material was not changed,and was in line with the requirements of *** was in line with national *** and modified IOLs s cytotoxicity were 1 and 0.6 grade *** rates of modified and unmodified were both less than 5%.Conclusion:Ion beam sputtering deposition of objects didn t only affect the surface morphology and the basic optical performance,but also can enhance the biocompatibility of intraocular *** beam sputtering deposition technique has provided new methods for the surface modification of IOLs and PMMA materials.
