Phaco – Emulsification Using Rotating Needle – A Newer Cheaper Technique

This Phaco-emulsification device is cheap to build, easy to operate, effective for treating patients with Cataract, the device will use low power; Torque using Simple DC Motor. This method of using rotating needles was used by Dr. Charles D. Kalmen. I was able to overcome the problem, i.e. spinning of the lens in A/C. The device has two parts, Body and Tube Body contains a motor and a wire connecting the power source with a foot-switch. The motor has a shaft enabling the needle to spin. The tube has a broad base attached with body and a tapered end containing Yousuf’s Needle. Yousuf’s Needle is made by incorporating 3-4 hypodermic needles in a silicon tube .It become easy to penetrate, generate low heat; low angular acceleration, hence does not cause undesired effect during procedures. It was tested on wood in the first stage. Following that, samples of 50 human lenses were collected after doing SICS and used by selecting them in random but purposive manner. When human lens were handled successfully, 50 goat eyes were operated. This cross- sectional study was done within a year. The device shows moderate penetrating capacity on wood. Goat’s lens was successfully emulsified by this device. There was no spinning of lens causing denuding corneal endothelium, no iris injury or Posterior Capsular rupture observed. Human lenses turned into jelly-like substances quickly, where hyper mature lens need more time to emulsify. So, this device hereby developed through the research should be given chance for further improvement
