Purpose To report the midterm endoth elial cell density measurements after posterior lamellar keratoplasty(Melles techniques).Design Cohort study.Methods Fifte en consecutive eyes of 15patients in whom a posterior lamellar keratoplasty procedure wa s performed for pseu-dophakic bullous keratopathy or Fuchsendothelial dystro-phy were evaluated.In 11corneas the donor tissue was inserted through a 9.0-mm sclerocorneal pocket incision(technique A );in four cases the donor was folded an d inserted through a 5.0-mm incision(technique B ).Specular microscopy was performed a t 6,12,24,and36months after surgery,to measure t he endothelial cell density.Results Mean postoperativ e endothelial cell density averaged 2,126cells /mm 2 (±548)at 6months,1,859cells /mm 2 (±477)at 12months,1,385cells /mm 2 (±451)at 24months,and 1,047cells /mm 2 (±425)at 36months.Conclusion In posterio r lamellar kerato-plasty,the donor corneal endothelium showed a decrease in cell density similar to that after conventional full-thickness penetrating kerato plasty.

The microscopic microscopy was performed at 6, 12, 24, and 36 months after surgery, to measure hemostatic cell density.
