THERE can be little controversy among modern ophthalmic surgeons regarding the advantages and desirability of the intracapsular method of cataract extraction.
As Arnold Knapp1 has pointed out in his classic paper:
The amount of literature that has arisen on the subject of the intracapsular extraction is bewildering, but some general direction can be recognized. The trend seems to be in favor of an operation in which a firm hold is taken of the capsule with the forceps without tearing it, concentrating the traction to one area and with a hook or similar instrument exerting pressure externally at the lower corneal margin, in order to raise vitreous pressure and to rupture the suspensory ligament at that point.... After subluxation of the cataract, the extraction is completed with the aid of external pressure, by tumbling or by head-first delivery.
Knapp and numerous others have fully reviewed the advantages of intracapsular cataract
