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.1This technology is known as Nd-YAG laser phacolysis (Figure 1).1The generation and propagation of shock waves created by this device,2as well as its effects on nontarget tissue have been carefully studied (L.T.D.S., J.M.D., unpublished data, 1990).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
