【摘要】：目的白内障手术亦被归为一种屈光手术,但鲜有针对患者手术前后眼球生物测定值的改变研究。文中通过白内障超声乳化加人工晶状体植入手术对前后A超眼球生物测定值的动态对比观察,统计分析其临床意义。方法连续动态观察南京军区南京总医院眼科2011年1月至2013年1月间行固定白内障手术188眼,采用A超分别对术前、术后14 d患者眼球生物值进行测定,包括前房深度、玻璃体腔深度、眼轴长度,并对手术前后患者坐、卧位的眼球生物值进行对比观测,另测量患者手术前后裸眼视力及眼压变化,对各项生物测定值进行统计学分析。结果手术前后视力[(0.17±0.19)vs(0.61±0.27)]及眼压[(15.09±8.50)mm Hg vs(12.99±4.44)mm Hg]变化差异均有统计学意义(P0.05)。手术前后前房深度改变差异有统计学意义(P0.05),手术前后坐位与卧位前房深度差异无统计学意义(P0.05)。手术前后玻璃体腔深度差异有统计学意义(P0.05),术前坐、卧位玻璃体腔深度差异无统计学意义[(16.568±2.406)mm vs(16.524±5.544)mm,P0.05],术后坐、卧位玻璃体腔深度差异有统计学意义(P0.05)。手术前后眼轴长度差异无统计学意义(P0.05)。结论白内障超声乳化加人工晶状体植入手术效果良好,患者的体位对A超测定无影响。
[Abstract]:Objective Cataract surgery is also classified as a refractive surgery. However, there were few studies on the changes of eyeball biometric values before and after surgery, and the dynamic comparison of A supereyeball bioassay values before and after cataract phacoemulsification and intraocular lens implantation was observed in this paper. Methods 188 eyes of ophthalmology of Nanjing General Hospital of Nanjing military region were treated with fixed cataract surgery from January 2011 to January 2013. The eyeball biological values of patients before and 14 days after operation were measured by A-scan respectively. The depth of anterior chamber, the depth of vitreous cavity, the length of eye axis, the biological value of eyeball in sitting and lying position of patients before and after operation were observed, and the visual acuity and intraocular pressure of patients before and after operation were measured. Results the changes of visual acuity [0.17 卤0.19)vs(0.61 卤0.27] and intraocular pressure [15.09 卤8.50)mm Hg vs(12.99 卤4.44)mm Hg] were statistically significant before and after operation (P 0.05). There was no significant difference in the depth of anterior chamber in supine position (P 0.05), but there was significant difference in depth of vitreous cavity before and after operation (P 0.05). There was no significant difference in the depth of vitreous cavity in supine position [16.568 卤2.406)mm vs(16.524 卤5.544 mm]. There was significant difference in the depth of vitreous cavity in supine position (P 0.05). There was no significant difference in axial length before and after operation (P 0.05). Conclusion the effect of phacoemulsification and intraocular lens implantation is good, and the position of the patient has no effect on the measurement of A ultrasound.
