All eyes were of abnormal structure due to complications from prior intraocular surgeries and ocular trauma. Ocular complications observed included graft dislocations, high intraocular pressure（IOP）, IOL dislocations, macular edema and hyphema. Best corrected visual acuity（BCVA）, IOP and mean central endothelial cell density（ECD） were recorded.RESULTS： Thirteen eyes had a history of ocular trauma, 10 eyes had an anterior chamber IOL, 16 eyes had prior vitrectomy. The iris was abnormal in 22 cases. Graft dislocation occurred in 5（17.2%） of 29 eyes. IOL dislocation occurred in 2 eyes（6.9%）. High IOP was found in 9 eyes and was controlled with treatment. The preoperative mean BCVA was 20/286. The 6 mo postoperative mean BCVA was 20/42. The average center ECD was 1965.3 cells/mm^2 at 6 mo, and the rate of the donor cell loss was 34.7%.CONCLUSION： DSAEK combined with artisan aphakia IOL implantation is an alternative option for resolving endothelial and lens disorders in aphakic eyes without capsular support. However, it should be performed cautiously for eyes with severe iris defects.展开更多
