目的 :通过对准分子激光原位角膜磨镶术术中患者头位改变的观察 ,探讨术中患者头位对手术疗效的影响。方法 :选择接受准分子激光原位角膜磨镶术治疗的近视患者 40 0例 (80 0眼 ) ,分为实验组和对照组 ,实验组在完成准分子激光原位角膜磨镶术角膜瓣后 ,观察记录患者头位 ,在继续进行手术前 ,对头位改变的患者予以调整 ,对照组给予常规护理 ,不予调整头位。对两组手术疗效予以对比分析。结果 :完成角膜瓣后明显改变头位的有 11.2 5 %;术后 6个月裸眼视力实验组优于对照组 ;对照组激光切削偏离中心及散光轴位矫正偏移发生率均大于实验组。结论 :准分子激光原位角膜磨镶术术中患者头位有不同程度的改变 ,头位的改变对手术疗效有一定程度的影响 ,进一步做好准分子激光原位角膜磨镶术术中患者的心理护理、协助手术医师发现及纠正患者术中头位变化是十分必要的。
OBJECTIVE: To investigate the effect of intraoperative head position on surgical outcome by observing the change of head position in patients undergoing laser in situ keratomileusis. Methods: Forty cases (80 0 eyes) of myopia treated by laser in situ keratomileusis were divided into experimental group and control group. After the corneal flap was prepared by laser in situ keratomileusis , Observing and recording the patient’s head position. Before the operation was continued, the patient with the head position change was adjusted, while the control group was given routine nursing care, and the head position was not adjusted. To compare the two groups of surgical treatment. RESULTS: After the corneal flap was completed, the head position was significantly changed to 11.2 5%. The uncorrected visual acuity test group was superior to the control group at 6 months after operation. The incidences of off-center and astigmatism axial offset in the control group were higher than those in the experimental group. CONCLUSIONS: The head position of patients undergoing laser in situ keratomileusis is changed to some extent. The change of head position has a certain degree of influence on the curative effect of the surgery, and the patients in the field of excimer laser in situ keratomileusis Psychological care to help surgeons find and correct intraoperative head changes in patients is very necessary.
