The mechanical performance of ophthalmic surgical needles is studied. Standard biomechanical tests, devised to evaluate the performance of ophthalmic surgical needles, are presented. Four comparable groups of ophthalmic surgical needles were selected from two different manufacturers for these biomechanical studies. The results of this testing demonstrate that needle point geometry and needle composition are important determinants of needle performance. When comparable size needles were evaluated, the biomechanical performance of the recently introduced CS160-6 ophthalmic needle (Ethicon, Inc) was superior to the AU-5, CU-5, and SU-5 needles (Alcon, Inc). Whereas the development of these biomechanical tests has allowed the evaluation of these ophthalmic needles, these same tests can be used to assess the performance of other new ophthalmic surgical needles.
对眼科手术用针的机械性能进行了研究。介绍了为评估眼科手术用针性能而设计的标准生物力学测试。从两家不同的制造商中挑选了四组具有可比性的眼科手术用针进行这些生物力学研究。该测试结果表明，针尖几何形状和针的成分是针性能的重要决定因素。在评估尺寸相当的针时，最近推出的CS160 - 6眼科针（Ethicon公司）的生物力学性能优于AU - 5、CU - 5和SU - 5针（Alcon公司）。虽然这些生物力学测试的开展使得能够对这些眼科针进行评估，但同样的测试可用于评估其他新型眼科手术用针的性能。
