Fragmentation of the Cataract: The ultrasonic probe is inserted into the eye through a small incision.It generates high-frequency vibrations (ultrasonic waves) at the tip of the probe.
Breaking Down the Cataract: The ultrasonic waves are used to break down the cataract, which is a clouding of the lens in the eye. The vibrations emulsify(combine) the cataract into tiny fragments.
Suction and Removal: Simultaneously, the probe uses suction to remove the fragmented cataract from the eye. The probe’s tip is designed to aspirate(take in) the emulsified(combined) cataract pieces efficiently.
Precision and Control: The surgeon can control the intensity and duration of the ultrasonic vibrations, allowing for precise removal of the cataract. This level of control helps minimize damage to surrounding eye tissues.
Replacement with an Intraocular Lens (IOL): Once the cataract is removed, an artificial intraocular lens (IOL) is often implanted to replace the natural lens. The IOL helps restore vision and focus light onto the retina.
Safety Measures: Ultrasonic probes used in cataract surgery are equipped with safety features to prevent damage to the eye. These features include sensors that monitor fluid pressure within the eye and automatically adjust the ultrasonic power to maintain safe levels.
