The newest advance in cataract surgery – Femtosecond Laser Surgery and the Capsulotomy
Cataract surgery has always been on the leading edge of innovation and the latest development is no exception. There are numerous advantages of Femtosecond Laser Cataract Surgery and in this blog I am going to limit the discussion to the capsular incision. The first thing to understand about this procedure is the incredible accuracy achieved. Using suction to hold the eye immobile, a built in imaging system identifies the different structures to the surgeon who then verifies that the software has correctly identified where the incisions are to be made. The laser then makes these incisions with an accuracy that cannot be matched by human hands.
The capsular incision or Capsulorhexsis should be a perfect 5mm circle which is centered on the lens. This anterior capsule is actually the covering or bag in which the cataract resides and the art of the surgery is to make this opening, remove the cataract from the capsule or bag and then place an artificial lens (IOL) back into the bag. The Capsulorhexsis size and location is critical in relation to where in the eye the IOL will stay after the surgery. The position of the IOL determines how the patient will see after the surgery. If the opening is too small, the IOL will be pushed back and the patient will be far-sighted; if too large, it will move forward and the patient will have myopia.
