Abstract Details


To describe a new diagnostic sign and improved technique for cataract extraction in cases with posterior lenticonus.


Faculty of medicine, Cairo University, Egypt


A consecutive series comprised of 16 eyes of 15 patients with definite or suspected posterior lenticonus were diagnosed and surgically treated by a modified technique to prevent premature opening of posterior capsule


Sixteen eyes of 15 patients with posterior lenticonus were included in this study. Mean patient age was 5±1.4 years (range, 3-7 years). Thirteen eyes (81.25%) were males and 3(18.75%) were females. The left eye was more commonly affected (10 eyes). The mean axial length was 23.72. The mean keratometry was 43.75.The posterior cone can be seen in early cases, but is obscured by the cataract in advanced cases. We have recognized irregular posterior opacity as a sign of posterior lenticonus. This sign was positive in all 16 eyes. Our technique for cataract extraction prevented premature opening of posterior capsule.


We were able to predict the presence of posterior lenticonus in our cases by observing the cataract limited to the subcapsular and cortical region with an irregular edge. The sign of irregular, ill-defined cataract edge was present in all advanced cases. Recognition of these cases is important for proper management and optimal visual prognosis.
