The main manifestation of cataract is progressive and painless vision loss. The time of visual impairment varies depending on the location of the cloudiness, and surgery for cataract is the only internationally recognized and effective treatment method.
The main symptoms of cataract are vision loss and blurred vision with gradually increasing vision loss without eye redness or eye pain, without visual distortion, with darker or yellowish objects, and with possible glare or double vision. Surgery is an internationally recognized effective treatment method. Currently, the mainstream surgical method is cataract ultrasonic emulsion aspiration combined with folded IOL implantation, which has a small incision, fast surgery, little pain for the patient, fast recovery, good surgical effect and low cost; this surgery uses ultrasound to crush the lens nucleus in the eye, and the overflowing ultrasound energy can damage the intraocular tissues at the same time. Therefore, this procedure is not suitable for patients with advanced cataract who have overripe cataract and hard lens nucleus. If cataract patients choose to perform ultrasound emulsification surgery, do not wait until the vision is too low, otherwise there will be great intraocular damage and slow recovery after surgery. This surgery is interlocked and done in one step. If not done properly, more serious complications can occur and it is recommended to find an experienced cataract specialist to perform the surgery.
In conclusion, cataract is mainly manifested as progressive and painless vision loss. Surgery for cataract is the only internationally recognized and effective treatment method, and it is recommended to find an experienced cataract specialist to perform the surgery.
