1-15. PROCEDURES IN THE TREATMENT OF CATARACT
a. General. Cataract is a clouding or an opacity of the crystalline lens, its capsule, or of both. A cataract may result from local or systemic disease, from eye injury, or the cataract may be congenital. Cataracts seen in the elderly are referred to as primary or senile cataracts. Medical treatment of cataracts is not available. Only surgical removal of the lens is of any significant assistance and this is indicated when the patient's vision is sufficiently depressed.
b. Operative Procedures.
Figure 1-4. Intracapsular lens extraction.
c. Precautions After Surgery. After surgery, the patient is usually kept at bed rest for a short period, then gradually allowed to ambulate, depending on postoperative conditions. All patients are generally cautioned not to stoop over, lift heavy objects, or strain themselves physically. This warning is maintained during the time when the wound is healing.
