Cataracts are a condition of the lens of the eye that has turbidity due to several factors. Some of these are caused by prolonged contact with ultraviolet light em>, radiation, and secondary effects of other diseases, such as diabetes or hypertension. In addition, cataracts can also be caused by old age and trauma.
Phacoemulsification is a cataract surgery technique using an ultrasonic wave that has an incision, or the width of the incision is only 2.20 – 2.75 mm. With this tool the cloudy lens will be split into several parts and then sucked (vacuum) with the tool and then installed a folding lens (Foldable Intra Oculer Lens ). The advantages of this technique are minimization of incision wounds, less risk of infection, no seams, and faster healing. With this technique as thin as any cataract, surgery can be done and without waiting to mature. The surgery is performed under local anesthesia and takes between 10-15 minutes. Patients do not need to be hospitalized after surgery and can be active as usual.
Previous cataract surgery techniques used ECCE (Extra Capsular Cataract Extraction) and ICCE (Intra Capsular Cataract Extraction) which required a cut width of around 8.0 – 10.0 mm because cloudy lenses had to be taken intact, so stitches are needed, and recovery will take a long time. As technology developed, cataract surgery techniques were increasing until now a new technique was discovered, phacoemulsification.
