摘　　要：Background:Complete nuclear disassembly of superhard cataracts cannot always be achieved by phaco chop,which is considered one of the best techniques for dealing with hard cataracts.We present a phaco chopprogressive cracking technique to divide superhard cataracts completely.Case presentation:We presented a case of cataract with over Grade V nucleus sclerosis and very low density of corneal endothelial cell(812 cells/mm^(2)).By performing the cataract surgery with our phaco chop-progressive cracking technique,the corneal endothelial cells were well protected and the patient’s visual acuity was markedly improved from finger counting at 40 cm to 20/200 the day after surgery without obvious corneal edema.Conclusions:Although an initial learning curve was needed,this phaco chop-progressive cracking technique could be of particular benefit to the superhard cataract,especially in patients with low density of corneal endothelial cells.
