The friction force of 5-ml, 2-ml, and 1-ml syringes used for manual aspiration of cortex material in extracapsular cataract extraction (ECCE) were compared. It was found that for a 5-ml syringe the force was 500 g, for a 2-ml syringe it was 250 g, and for a 1-ml tuberculin-type syringe it was only 50 g. The ease and duration of cortex aspiration in 30 cases of ECCE were compared using each of the above syringes partially filled with fluid, connected to a 25-gauge Gill's type cannula, and a closed anterior chamber technique. It was found that with the help of a 1-ml tuberculin syringe, cortex material was removed faster and with less finger fatigue than with the 5-ml or 2-ml syringe.
比较了在囊外白内障摘除术（ECCE）中用于手动抽吸皮质物质的5毫升、2毫升和1毫升注射器的摩擦力。结果发现，5毫升注射器的力为500克，2毫升注射器的力为250克，而1毫升结核菌素型注射器的力仅为50克。使用上述每种部分填充液体、连接到25号吉尔氏套管并采用封闭前房技术的注射器，比较了30例ECCE中皮质抽吸的难易程度和持续时间。结果发现，借助1毫升结核菌素注射器，与5毫升或2毫升注射器相比，皮质物质去除得更快，手指疲劳也更少。
