摘要
目的分析并探讨准分子激光原位角膜磨镶术(LASIK)手术前后视野改变情况,并对LASIK手术治疗安全性进行探讨。方法选取2010年6月～2011年12月湖南常德市第一人民医院收治的125例行LASIK的近视患者的临床资料。观察组63例均为中低度近视,对照组62例为高度近视,由一位医师按常规LASIK手术方式进行。对比两组患者术后1周、3个月后的MD及PSD值。结果所有患者手术平均时长(15.8±2.3)min,术中患者无并发症发生,术前、后眼底前段并眼底检查无明显异常,术前、后眼压检查均正常。两组患者视力矫正情况与手术前对比,差异有统计学意义(P<0.05)。两组患者术后MD值变化趋势均一致,即在术后呈上升趋势,其中1周后的MD值与术前对比,差异有统计学意义(P<0.05),两组患者PSD值术后均有所上升,其中对照组患者1周左右PSD值与术前对比,差异有统计学意义(P<0.05),3个月内呈逐渐上升趋势,3个月后PSD值与术前对比,差异无统计学意义(P>0.05),两组对比PSD值差异有统计学差异(P<0.05)。结论行LASIK手术在术后早期可对患者视野产生一定影响,高度近视患者均明显。随着时间的推进,这种影响只是短暂、轻微且可逆的,因此可以认为LASIK是一种较为安全、有效的治疗近视的手术方法。
Objective Analyze and explore the visual field changes before and after LASIK, and LASIK surgery security to explore. Methods Choose the hospital from June 2010 to December 2011 were 125 cases of myopia LASIK patients with clinical data, patients were divided into observation group of 63 cases, all patients with low to moderate myopia, the control group of 62 cases of high myopiaby a physician according to conventional LASIK surgery. Compared two groups of patients one week, three months after the MD and PSD values. Results All surgical patients average length （15.8±2.3） min, patients with intraoperative complications, preoperative fundus preceding and fundus examination was normal, preoperative IOP examination were normal. Two groups of patients with vision correction with the pre-operative contrast, with a significant difference （P〈0.05）. Patients in both groups the MD value of the trend, an upward trend that the postoperative one week after the MD value of preoperative contrast with significant differences （P〈0.05）, two groups of patients after PSD value have increased, in which the control group of patients PSD value in about one week before surgery compared a significant difference （P〈0.05）, with gradual increase in the three months, three months after the PSD value of preoperative contrast no significant difference （P〉0.05）, two sets of contrast PSD value statistically significant （P〈0.05）. Conclusion LASIK surgery in the early postoperative time for patients horizons have a certain impact, and high myopia are obvious. As time progresses, this effect is only temporary, mild and reversible, so that LASIK is a relatively safe and effective surgical method of treatment of myopia.
