Intraocular lenses with intracapsular cataract extraction.

Excellent results are obtainable with well-proved lenses. For those using intracapsular methods, I can give assurance that it is not necessary to change in order to use intraocular lenses safely. The prerequisites are an established safe technique for routine cataract surgery with good visual results. Proper wound closure should be demonstrated by an absence of cases of shallow or absent anterior chamber, of iris prolapse, or postoperative hyphaema. No intraocular lens of any kind should be used unless the quality of routine cataract surgery is high in these respects as well as in avoiding damage to the corneal endothelium. The choice of intraocular lens should be one which can be applied to the surgeon's well-established method and it should also be a well-established lens which has a safe long-term record.
