Cataract intraocular lens surgery is to take out the original cloudy lens and put in a new intraocular lens. The intraocular lens implantation in ICL does not need to remove the original lens, but to place an intraocular lens between the iris and the lens, just like wearing a pair of contact lenses, which can correct high myopia while retaining its own lens accommodation ability.
Therefore, the difference between cataract intraocular lens implantation and ICL intraocular lens implantation is whether it is necessary to remove the lens.

Moreover, the principle of cataract intraocular lens surgery is actually very simple. Simply put, it is to replace the "lens" for the eyes. The operation process is as follows:
1. Make three small incisions at the edge of cornea, one main incision and two pairs. The main incision is about two to three millimeters long, which is the main wound, allowing the phacoemulsification stick and intraocular lens to pass through, and the other two auxiliary incisions allow surgical instruments to pass through.
2. Use capsulorhexis forceps to tear an anterior capsule opening with a diameter of about 5 mm, so as to take out the cataract cortex and nucleus.
3. Carry out "water separation" to separate the cortical tissue from the external capsule.
4. Dissolve and suck out the cataract nucleus and cortical tissue with ultrasonic emulsification stick.
5. Grinding the external capsule to reduce the chance of inflammation and turbidity of the external capsule after operation.
6. Install the intraocular lens.
The above is the procedure of cataract intraocular lens surgery.
