Principles of Cataract Surgery

ABSTRACT

In surgical removal of cataractous lens the following principles should be kept in mind. (1) Remove the lens as completely as possible, without leaving the lens remnants in the pupillary area in order to achieve the best vision as possible. (2) Ocular tissues should suffer the minimum injury during the operation. This precaution can be applied especially to the corneal endothelium and the iris. (3) No derangement of the vitreous surface should occur. (4) Secure the corneo-scleral wound as tight as possible with care not to incarcerate lens tissues nor vitreous. Application of these principles to the individual cases was discussed.
