Abstract
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 chop-progressive 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.
