摘要
目的:探讨老年人白内障超声乳化术后低视力原因。方法:调查老年人群白内障超声乳化术后低视力病例48例54眼,跟踪询问相关病史,收集相关资料,包括术前检查、术后随访、数据汇总,分析归纳低视力的原因。结果:患者48例54眼术后1mo最佳矫正视力<0.3,其中青光眼视神经损害5眼(9%),角膜斑翳白斑5眼(9%),角膜水肿失代偿1眼(2%),高度近视弱视11眼(20%),老年性黄斑变性10眼(18%),黄斑前膜、黄斑裂孔9眼(17%),糖尿病性视网膜病变9眼(17%),视网膜分支静脉阻塞2眼(4%),视网膜脱离复位术后1例1眼(2%),视网膜色素变性1眼(2%)。结论:眼底病变是导致白内障术后低视力的重要原因,对低视力高危患者,术前要引起足够重视,严格术前检查并遵守操作规程,可减少手术后低视力的发生,减少医疗纠纷。
AIM：To investigate the factor of low visual acuity after phacoemulsification on senile cataract. METHODS： Forty-eight patients 54 eyes with senile cataract were collected ,which presented low visual acuity after phacoemulsification and IOL implantation. Medical history,and medical examination of patients before and after operation were collected and the factor of low visual acuity were analyzed. RESULTS. In 48 cases 54 eyes,the best postoperative corrected visual acuities were 〈 0.3, among which optic never injury in glaucoma were 5 eyes （9%）, corneal leu- coma and macula were 5 eyes （9%）, corneal edema decompensation was 1 eye （2%）, high myopia and amblyopia were 11 eyes （20%）, senile macular degener- ation were 10 eyes （18%）, macular membrane and hole were 9 eyes （17%）, diabetic retinopathy were 9 eyes （17%）, branch retinal vein occlusion were 2 eyes （4%）, reattached retina of retinal detachment was 1 eyes （2%）, retinitis pigmentosa was 1 eye（2%）.o CONCLUSION.The pathological change of mportant reason for the low visual fundus is an acuity after phacoemulsification.To patients with high danger of low visual acuity, inspect strictly and comply with rules before operation can lower the rate of the low visual acuity after phacoemulsification and reduce medical dispute.
