3 pieces of desiccated corneal grafts taken from normal subjects and preserved for 2-7 years were rehydrated for 20 minutes and examined in comparison with the normal fresh cornea, no differences were found in transparency and microscopic appearance. Projection electron microscopic examination revealed the same arrangement of collagen fibers, but in fibroblasts of the preserved cornea, cytoplas-mic membranes were broken, cell organelles were not clear enough and nuclear membranes were not intact, though no effect on transparency of the cornea was observed. Histochemically, staining with al-cian blue of the preserved cornea after rehydration for 20 minutes showed the same result as in the fresh cornea. Hemotoxylin and eosin staining of the cornea preserved for 7 years and rehydrated for 30 minutes revealed edema of the stroma and the disorderly arrangement of fibers and cells. In the cornea rehydrated for 60 minutes, the above changes became more obvious. After staining with alcian blue,the stroma of the preserved cornea after rehydration for 30 minutes was thicker than that of the normal one and took a light and uneven staining. The above phenomena were more pronounced in the cornea rehydrated for 60 minutes.By clinical and laboratory studies, it was assumed that the long-term preserved cornea by desiccation could be available clinically, but one must take care that the time for rehydration should not be so long as to free the cornea from edema and opacity, and not to affect the effect of keratoplasty as well.

将保存2~7年的3个正常人干燥角膜片复水20分钟与正常人新鲜角膜作对比检查。干燥保存角膜的透明性与新鲜角膜相同;光镜检查与新鲜角膜在形态上无差别;透射电镜检查二者的胶原纤维排列相同,仅干燥保存角膜的纤维母细胞的细胞膜有断裂,细胞器不够清楚,核膜不够完整,但不影响角膜的透明性;组织化学检查,复水20分钟者,aleian blue染色与新鲜角膜相同。干燥保存7年的角膜复水30分钟者(HE染色),基质水肿、纤维及细胞排列不整齐,复水60分钟的变化较30分钟者更甚。alcian blue染色检查,复水30分钟者角膜基质较正常者厚,染色淡,不均匀,复水60分钟者则更甚。临床证明,干燥长期保存角膜可以应用,但应注意复水时间不可过久,以防角膜水肿、混浊,影响手术效果。

Six New-Zealand white rabbits were divided into two groups,3 rabbits(6 eyes)in each group.The epithe-lium of the central area of the cornea was removed under veiious anesthesia,and each cornea of both groups wasirradiated by Er:YAG Iaser with 100~140mJ,0.32cm(fluence of 1250~1750mJ/cm2),150μs,1Hz for 60shots in groupⅠand 120 shots in group Ⅱ,respectively.The eyes were examined with a slit-lamp and enucleated at 3 days,1 month and 4 months postoperativelyfor light microscopy and scanning electron microscopy.Immediately after the Er:YAG laser procedure,whiteyellowish coagulation patches in the ablation area could be seen.In general,th epithelium was repaired com-pletely at approximately 4-8 days postoperatively.Stromal haze could be observed which was most significant at3 to 4 weeks postoperatively.At that time,the epithelium and the underlying stromal collegen fibrils showed hy-perplasia and disorganization.The corneas became clear essentially 4 months postoperatively.All of thesechanges were more significant in group Ⅱ.The possibility to use the Er:YAG Iaser in corneal surgery and its ad-vantages were discussed in this paper.

新西兰白兔6只,分成1、2两组,每组3只(6眼)。在静脉麻醉下刮去角膜中部上皮,用Er:YAG激光100~140mJ、0.32cm(能量密度为1250~1750mJ/cm2)、150μs、1Hz,分别照射1组每眼60次,2组120次。术后进行裂隙灯检查,并于术后3周、1月和4月摘下眼球,分别作光镜及扫描电镜检查。激光照射后即见到角膜表面出现黄白色凝固层。一般4~8天上皮修复完毕。术后3周至1月角膜基质混浊最明显,此时出现上皮过度增生,基质胶原纤维增殖,排列紊乱。术后4月角膜基本恢复透明。以上表现均以2组更为明显。本文并对Er:YAG激光进行角膜手术的可行性及优点进行了讨论。

corneas of five.New-Zealand white rabbits were irradiated by arF excimer laser of 70-80 mJ energy.3×4 mm spot size,fluence of 583-667 mJ cm2.at a frequency of 3 Hz with pulse duration of 30 ns on the cen-tral area for 360 shots.The corneal epithelium of the central area was removed by scraping before irradia-tion.The lesions were examined immedately.1 day.2 days,3 days,1 week,2weeks,3 weeks,1 month,2months, 3 months 4 months postoperatively with a slit-lamp biomicroscope.Corneas were dissected at 3days.2 weeks,1 month, 2 months and 4 months postoperatively for light microscopy and scanning electron mi-croscepy . Corneal epithelium repaired completely within 3 days after irradiation, Stromal haze was significant at 3 weeks postoperatively.4 months after irradiation, corneas became almost clear, and the arrangement of stromal collagen fibers showed regularity and parallel to the cornea surface, however some epithelium hyper-plasia was still present.

新西兰白兔5只(10只眼),用ArF准分子激光能量70~80mJ,光斑3×4mm,能量密度583-667mJ/cm2,脉宽30ns,频率3Hz,分别照射角膜中部360次脉冲,照射前用刀片刮去角膜中部上皮,术后当时,1天、2天、3天、1周、2周、3周、1个月、2个月、3个月和4个月进行肉眼及裂隙灯检查,并于术后3天、2周、1月、2月和4月取下角膜,分别作光镜及扫描电镜检查。角膜上皮于术后3天内愈合,基质混浊于术后3周最明显,术后4月角膜几乎完全透明,角膜基质胶原纤维排列整齐,与角膜表面平行,但尚有些上皮过度增生。
