To observe the effect of extracting lens on the damage of corneal endothelium in vitreous and retinal surgery.
The corneal endothelial cell densities of 179 eyes were observed preoperatively and at postoperative 2, 4, 8 weeks and 3 and 6 months.
Postoperatively, there was no significant change of the corneal endothelial cell densities compared with that of the preoperative ones in phakic eyes among different operations. There was also no significant change of the cell densities, but an tendency of cell loss in the aphakic and pseudophakic eyes after vitreous and retinal surgery. The corneal endothelial cell densities decreased significantly after vitrectomy with lensectomy.
It is the vitrectomy with lensectomy that makes the corneal endothelial damage. Vitreous and retinal surgery poses a risk to corneal endothelium in the aphakic and pseudophakic eyes.
观察玻璃体视网膜手术中晶状体摘除对角膜内皮损伤的影响。
观察179只眼术前及术后2周、4周、8周、3个月和6个月时的角膜内皮细胞密度。
术后，不同手术方式的有晶状体眼中角膜内皮细胞密度与术前相比无显著变化。无晶状体眼和人工晶状体眼中细胞密度也无显著变化，但玻璃体视网膜手术后有细胞丢失的趋势。晶状体切除玻璃体切除术后角膜内皮细胞密度显著降低。
晶状体切除玻璃体切除术导致角膜内皮损伤。玻璃体视网膜手术对无晶状体眼和人工晶状体眼的角膜内皮有风险。
