Final answer:
Intracapsular cataract extraction is the procedure where the lens and its capsule are both removed to eliminate a cataract.
Step-by-step explanation:
The type of cataract extraction where the lens and its capsule are completely removed is known as intracapsular cataract extraction (ICE). This technique involves removing the entire lens within its capsule, thus eliminating the cataract. It is different from extracapsular cataract extraction, where the lens is removed but the posterior capsule is left in place to allow for intraocular lens implantation, which can correct vision for distance. The term phacoemulsification refers to the use of ultrasound waves to emulsify the lens before extraction and is a type of extracapsular surgery. Keratoplasty, on the other hand, is a surgical procedure on the cornea, not the lens.
