Cataract surgery is the most common form of cataract surgery.

Cataract surgery mainly includes phacoemulsification cataract extraction, extracapsular cataract extraction, intracapsular cataract extraction, femtosecond laser-assisted phacoemulsification cataract extraction, etc., and the specific surgical methods need to be determined according to the specific conditions of patients, and the doctor's suggestions. 1. Phacoemulsification is a surgical method that uses ultrasonic energy. After emulsification, the turbid lens nucleus, cortex and posterior capsule are removed and preserved. Phacoemulsification technology has been applied clinically since the 1960s. With the application of foldable intraocular lens, and the reduction of surgical incision, it has the advantages of small tissue damage, no suture of incision, short operation time, rapid visual recovery, small corneal astigmatism, etc., and can be completed under topical anesthesia. 2. Extracapsular cataract extraction The operation is the opacity of the lens nucleus and cortex removal and retention of the posterior capsule surgery. Because the integrity of the retention of the posterior capsule, reducing the interference and destruction of intraocular structures, to prevent the vitreous prolapse and complications caused by, while creating the conditions for the smooth implantation of posterior chamber intraocular lens. 3. Cataract capsular extraction This is the opacity of the lens completely removed from the eye of a surgery, the surgery requires a larger incision, because the lens capsule was removed at the time of surgery, so it can't implant posterior chamber intraocular lens at the same time. 4. Femtosecond laser-assisted phacoemulsification Cataract surgery This surgery uses femtosecond laser energy to change the curvature of the corneal surface, so as to achieve the purpose of correcting ametropia. Femtosecond laser-assisted phacoemulsification Cataract surgery has higher accuracy, predictability, and can reduce the damage to the cornea surgery.
