Extracapsular Cataract Surgery is a traditional method of cataract removal. It involves making a large incision in the cornea, removing the cloudy natural lens in one piece, but leaving the lens capsule (the thin membrane holding the lens) intact to support the new artificial lens.

The surgeon makes a large incision and uses specialized tools to remove the lens nucleus (the hard center) and cortex (the soft outer layer) from the capsule. This manual extraction requires a larger wound than modern techniques. The procedure is usually reserved for very hard, dense cataracts that cannot be dissolved by other means.
The main difference is the size of the incision and the speed of recovery. Extracapsular surgery requires a large incision (8-10 mm) and relies on stitches, leading to a longer healing time. Phacoemulsification uses ultrasound to break up and aspirate the lens through a tiny incision (2-3 mm) that is self-sealing.
The technique allows a large, rigid intraocular lens (IOL) to be inserted because the incision is large. The remaining capsule provides a stable pocket for the new IOL. The size of the incision often restricts the types of IOLs that can be used.
Extracapsular surgery is less common today because phacoemulsification is safer, faster, and allows for much quicker visual recovery. It is now primarily used for exceptionally dense cataracts or when phacoemulsification fails.
Necessary post-surgical precautions are stringent. Due to the large incision and stitches, the patient must avoid heavy lifting, bending, or rubbing the eye for several weeks to allow the wound to heal properly.
Yes, it is still performed globally, especially for very dense cataracts or in settings where advanced phacoemulsification is unavailable.
Yes, the larger incision often causes more surgical induced astigmatism and a longer period of visual recovery than phacoemulsification.
Yes, full recovery can take several weeks due to the size of the wound and the need for multiple stitches.
Consult your surgeon if you notice a sudden drop in vision or extreme pain after extracapsular surgery. Because this procedure uses a large incision, there is a higher risk of "Wound Leak" or infection (Endophthalmitis). Stitches may need to be removed months later to correct your vision.
