As cataract develops, vision loss will become more and more obvious, which will impact the patient’s daily life and work. When this happens, the patient needs to undergo cataract surgery and intraocular lens implantation. Cataract surgery has a very high success rate despite the unusual possibility of complications such as bacterial infection, intraocular hemorrhage, glaucoma and retinal detachment that cause vision problems in the future.
The surgeon inserts a soft, foldable intraocular lens. The wound is extremely small.
Conventional Cataract Surgery
In the old days, cataract surgery required the implantation of a large hard intraocular lens, and a wound of 10 to 12 mm would be left. In addition, injection of local anesthetic and post-surgery stitching were required.
Minimally invasive ultrasound phacoemulsification cataract surgery
Minimally invasive ultrasound phacoemulsification cataract surgery is a cutting-edge cataract procedure that only leaves a tiny wound of 2 to 3 mm. The surgery uses an ultrasound probe of the same diameter as the wound to emulsify, break up, and then suction out the cataract. The surgeon then inserts a soft, foldable intraocular lens. The resulting wound is extremely small and the whole process takes only about 10 minutes. No injections or stitches are required; only a few anesthetic eye drops are instilled. Painless local anesthesia of the corneal surface has replaced the conventional anesthetic injection, reducing the risks of anesthesia and patients’ fear. Moreover, the patient needs not be hospitalized. The surgery is a highly safe and effective method of treating cataract permanently.
The New Cataract Ultrasonic Emulsification Device
Technology is constantly improving. The new cataract ultrasonic emulsification device not only increases the effectiveness and safety of cataract surgery but also reduces surgical time and the risks of complications such as corneal injuries and post-surgery astigmatism. The success rate of cataract surgery has thus been increased substantially. And with the use of ever more advanced intraocular lens technology, patients’ quality of vision has been uplifted notably. After a minimally invasive ultrasound phacoemulsification cataract surgery, the vision of patients quickly recovers, and patients can enjoy clear vision and a good quality of life again. However, if the patient is suffering from other diseases, for example, diabetes, glaucoma or age-related macular degeneration, the improvement of the quality of vision will be limited even if the cataract surgery is successful.
