What types of cataract surgery are there?
This is also known as ‘Phaco’ and is the most common technique used for cataract removal today. It usually takes less than half an hour to remove a cataract through phacoemulsification, and requires only minimal sedation. Once the clouded lens is removed, an intraocular lens implant, also referred commonly as an IOL, is implanted in the natural lens capsule.
Extracapsular Cataract Surgery
This cataract procedure is used in cases of highly advanced cataracts, which are too dense for phacoemulsification or when phacoemulsification is not possible for various other reasons. The cataract is removed in one piece instead of being fragmented within the eye as is done in Phacoemulsification. Just like phacoemulsification, an artificial lens (IOL) is placed inside the same natural lens capsule. Extracapsular Cataract Surgery results in slower recovery of the wound as well as visual function.
Intracapsular Cataract Surgery
Though rarely used nowadays, Intracapsular Cataract surgery requires an even larger incision as compared to Extracapsular surgery, through which the entire lens with surrounding capsule is removed. The IOL (intraocular lens) is placed in a different location, in front of the iris, in this surgical procedure.
Laser Assisted Cataract Surgery
This uses a femtosecond laser system to assist in portions of the cataract surgery. This is an optional service that offers the most precise incisions and reduces the amount of energy needed to remove the cataract.
