In these cases, cataract surgery may be required to allow proper treatment of the other eye problem. Your doctor will discuss the options with you and together you will decide which type of removal and lens replacement is best for you. There are 3 different types of surgery that can be used to remove lenses that have a cataract. Phacoemulsification is done by softening the lens with sound waves and then removing it through a needle. The back half of the lens capsule is left behind.
Intracapsular surgery involves surgically removing the entire lens, including the capsule.
This is done very rarely. The artificial lens is a plastic disc called and intraocular lens. It is placed in the lens capsule inside the eye. Other options include contact lenses and cataract glasses. You and your doctor will decide which choice is best for you.
