| Outline of Final Research Achievements |
We conducted experiments to test intraocular toxicity of non-swelling hydrogel as a intraocular tamponade using rabbit eyes. There was limited postoperative inflammatory response, no intraocular pressue elevation or sign of hydrogel opacity. Retinal microstructure and retinal function was normal. We concluded that this hydrogel could be used safely as a intraocular tamponade. The material we used, however, was non-degradable hydrogel. To establish a sutable material for clinical use, we continue our research to fabricate degradable non-swelling hydrogel and evaluate its safety and feasibility as a intraocular tamponade.
