My method of extracapsular cataract extraction with implantation of a posterior chamber intraocular lens

Simplified manual forms of extracapsular cataract extraction appear to be more economical, yet as safe and simple as techniques employing more complex instrumentation. The following method, employed in 40,000 cases, seems to the author to be an efficient and effective way of performing cataract extraction. One hour prior to surgery, modified retrobulbar anesthesia alone is employed using the technique described, and provides adequate akinesia as well as anesthesia. Positive pressure is applied to the eye preoperatively to assure softness of the globe at the time of surgery. An anterior capsulectomy is made with scissors, using the open-sky technique. Following the delivery of the lens nucleus and as much cortex as possible with a lens loop, the remaining cortex is removed with an angled, 23-gauge, double irrigation-aspiration cannula. Filtered balance salt solution, containing gentamycin flows into the eye through the side port (inflow) and a 3-cc syringe with 2 cc BSS for irrigation-aspiration is connected to the other (aspiration) port. A single, 25-gauge, angled irrigation cannula is used to clean up the finger cortical remains. A firm-loop intraocular lens is inserted into the capsular bag. The posterior capsule is left intact.
