As is known, with the development of ophthalmic diagnosis and treatment, people have come to get more and more knowledge about ophthalmic diseases, and in order to more comprehensively and carefully investigate the characteristics and development mechanism of the diseases, intraocular fluid (including aqueous humor and vitreous humor) becomes an indispensable tissue material for ophthalmologists to recognize various ophthalmic diseases such as diabetic eye complications, cataract, glaucoma, uveitis and the like, and aqueous humor is located in the anterior chamber and has a volume of about 0.15-0.3ml. In cataract surgery, it is often necessary to withdraw aqueous humor from the anterior chamber, either as a disease study or as a control sample. The conventional operation procedure is as follows:
