According to reports from National Health Insurance Administration of Taiwan, there are over 10 thousand ophthalmological operations conducted each year. Oculae irrigating solution plays an important role during those surgeries. Good oculae irrigating solution ensures the integrity of the tissue, and prevents damages to the cells by providing proper otmosis pressure and energy to the cells, and maintains the thickness of the corneal tissues. Moreover, along with the development of surgical techniques, traditional removal operations are gradually replaced by ultrasound to pulse the damaged tissues into fractures. Therefore, damages to nearby-tissues by ultrasound becomes the next problem to be solved.
