| PURPOSE﹕To develope a new technique for soft-nucleus cataract extraction by micro incision without phacoemulsification machine.
METHODS﹕ After making a about 5.5mm capsulorhexis , Hydro-dissection and hydro-delineation were performed until the soft nucleus and parts of cortex of cataract model porcine eye were prolapsed out of the capsule. Then an irrigation chopper which was shaped from a 22-gauge needle and an aspiration chopper which was fashioned from a 23 Gauge needle were used to chop, dislodge, hydrate, and loosen the soft nucleus and the sticky cortex into small pieces and meanwhile aspirate them out by an assistant using a 50cc syringe. Once all the cortex were removed, an IOL was implanted into capsule bag.
RESULTS﹕20 postmortem porcine eyes were successfully performed in this way with the result of clear cornea, fine capsular bag remained without any rupture, IOL in good position and corneal incision sealed well after slight stromal-hydration.
CONCLUSION﹕ This technique enables successful soft-nucleus cataract extraction without phacoemulsification equipment and other special instruments. This method is very easy and practical for congenital cataract ,premature senile cataract, and clear lens extraction particularly in less developed and developing countries which can not afford to expensive equipment.
