There must be a reason why many concepts are deeply rooted in people’s minds, just like cataracts need to be ripe before they can be removed, this concept is really deeply rooted in people’s minds. With the development of science and technology, cataract surgery is becoming more and more minimally invasive. Nowadays, cataract ultrasound emulsification surgery is the most popular surgical procedure, and as the incision becomes smaller and smaller, the balance of ultrasound energy and negative pressure, the surgical reaction becomes smaller and smaller, and the recovery becomes faster and faster. So as surgical techniques and everyone’s quality of life requirements continue to improve, cataracts can increasingly be treated at an early stage and many of the complications arising from late cataracts can be avoided. So as patients’ requirements for visual quality continue to improve, cataract removal by maturity is now an outdated concept! Of course, it does not mean that a cataract must be treated immediately with surgery, it needs to be judged by the doctor in conjunction with the individual patient’s condition and requirements!
