目的 评价 AOV- FB眼科准分子激光治疗仪矫正近视的有效性、预测性和安全性。方法 选用新西兰家兔 16只 ,按眼别分成 2组 ,自身对照 ,均行 PRK手术。实验组 :右眼 ,AOV - FB准分子激光眼科治疗仪组 ,预期矫正度数 -2 .0 D。对照组 :左眼 ,L asersight- 2 0 0 0准分子激光眼科治疗仪组 ,预期矫正度数 - 2 .0 D。按手术前后屈光度的改变判断其效果 ;观察术后反应情况及并发症 ,以探讨其安全性。进行病理形态学观察 ,以比较 2组差异。结果 实验组矫正近视与对照组在手术效果、术后反应、并发症、术后病理改变均无显著差异。实验组术后 3个月在组织学上角膜结构已基本正常。结论 AOV- FB眼科准分子激光治疗仪矫正近视安全、有效 ,预测性良好 ,可进一步作临床应用研究。
Objective To evaluate the efficacy, predictability and safety of AOV-FB ophthalmic excimer laser in the correction of myopia. Methods Sixteen New Zealand rabbits were selected and divided into two groups according to their eyes. Their own control was performed with PRK. Experimental group: right eye, AOV - FB excimer laser ophthalmology instrument group, the expected degree of correction -2 .0 D. Control group: left eye, L asersight- 2000 excimer laser ophthalmic therapy unit, expected degree of correction - 2.0 D According to changes in preoperative and postoperative diopter to determine its effect; observed postoperative response and complications to explore its safety. Pathomorphological observation to compare the two groups of differences. Results The experimental group corrected myopia and the control group in the surgical results, postoperative response, complications, postoperative pathological changes were not significantly different. The experimental group 3 months after surgery in the corneal structure has been normal. Conclusion The AOV-FB ophthalmic excimer laser photocoagulation is safe, effective and predictive for myopia. It can be further applied in clinical research.
