方法：收集Ⅱ度及以上的中重度眼化学伤患者36例43眼的基本资料，通过分析致伤原因、致伤程度、视力、并发症等观察临床疗效。

结果：Ⅱ度烧伤的视力恢复效果较好，55.6%的视力恢复到0.6及以上。酸烧伤组视力恢复效果>0.3的为80.0%，碱烧伤组视力恢复效果>0.3的为56.0%，差异具有统计学意义(P<0.05)； 早期行羊膜移植组视力恢复效果>0.3的为69.7%，早期未行羊膜移植眼视力恢复效果>0.3的为50.0%， 差异具有统计学意义(P<0.05)。酸烧伤组严重并发症的发生率(40.0%)低于碱烧伤组(84.0%)，差异具有统计学意义(P<0.05)； 早期行羊膜移植组严重并发症的发生率(60.6%)低于早期未行羊膜移植组(80.0%)，差异具有统计学意义(P<0.05)。

结论：在烧伤急性期及时采取有效的处理措施、并及早开展羊膜移植，对于患者的视力恢复和减少并发症的发生有重要意义。

METHODS:Totally 36 cases(43 eyes)of Ⅱ degrees and above of ocular chemical injuries were collected, and clinical efficacy was observed by analyzing the causes of injury, the degree of injury, visual acuity and complications.

RESULTS:The recovery of visual acuity was well in Ⅱ degrees of burns, and the acuity of 55.6% reached over 0.6. The recovery of visual acuity >0.3 in acid burn group was 80.0%, and the recovery of visual acuity >0.3 in alkali burn group was 56.0%. The difference between two groups was statistically significant(P<0.05). The recovery of visual acuity >0.3 in early amniotic membrane transplantation group was 69.7%, and in early no amniotic membrane transplantation group was 50.0%; the difference between two groups was statistically significant(P<0.05). The incidence of serious complications of acid burn group(60.0%)was lower than the alkali burn group(84.0%), and the difference was statistically significant(P<0.05). The incidence of serious complications in early amniotic membrane transplantation group(60.6%)was lower than in early no amniotic membrane transplantation group(40.0%), and the difference was statistically significant(P<0.05).

CONCLUSION: Early clinical treatment, and early amniotic membrane transplantation are very important for patients with ocular burn in acute phase to reduce complications and have a better recovery.
