Neodymium-YAG Laser Phacolysis of the Human Cataractous Lens

The use of high powered neodymium (Nd)-YAG laser pulses to create shock waves after striking a metal target, and its implication for small-incision cataract surgery, has previously been described. 1 This technology is known as Nd-YAG laser phacolysis ( Figure 1 ). 1 The generation and propagation of shock waves created by this device, 2 as well as its effects on nontarget tissue have been carefully studied (L.T.D.S., J.M.D., unpublished data, 1990). In this case report, we describe the removal of a nuclear sclerotic cataract in a patient using this technology. Report of a Case Preoperative Examination and Diagnostic Studies . A 60-year-old diabetic black male had a 1-year history of gradual visual loss in both eyes. His best corrected acuity was 20/70 OD and 20/40 OS. His refraction was −0.50−0.50×10 OD and −1.00 − 0.75×40 OS. His pupils were normal. The patient had a 2+ nuclear sclerotic cataract in his right eye
