The visual acuity, dioptometry and corneal topography were investigated in a 12-month follow-up study.results the postoperative visual acuity of the 56 eyes(84.8%)was equal to or above the best corrected visual acuity before lasik.conclusion lasik for ametropia after cataract extraction and intraocular lens implantation is an effective and safe surgery.but the indication must be selected appropriately.

观察视力、屈光状态、角膜地形图情况。结果 56眼（84.8%）lasik术后视力均达到或超过术前的最佳矫正视力，10眼（15.2%）lasik术后最佳矫正视力下降1～2行。结论 lasik是矫治白内障摘除人工晶体植入术后屈光不正的安全、有效的方法。

This thesis proposed two methods of particle swarm optimization and genetic algorithm to optimal reactive power dispatch of transmission systems, respectively. The advantage of these methods is to achieve near optimal solution for discrete nonlinear optimization problem. So this thesis simulates the proposed method for IEEE 30-bus power system and a practical Taipower system.
