摘要
目的 观察老年性白内障摘除术后早期患者双眼视觉的恢复情况 ,并探讨影响其恢复的原因。方法 对 5 5例 (6 6只眼 )老年性白内障患者行囊外白内障摘除人工晶状体植入术 (ECCE组 )或超声乳化白内障吸除人工晶状体植入术 (PHACO组 ) ,术后检查矫正视力、屈光度数 ,以及双眼同视、融合及远、近距离立体视功能。结果 术前术眼视力ECCE组低于PHACO组 ,差异有显著意义 (P <0 0 5 ) ;术后术眼和非术眼视力两组比较 ,差异均无显著意义 (P >0 0 5 )。术后ECCE组双眼柱镜屈光度数差值较大 ,与PHACO组比较差异有非常显著意义 (P <0 0 1)。两组患者术后均具有较好的双眼同视和融合功能。ECCE组和PHACO组分别有 83 3%和 94 7%的患者获得不同程度的远距离立体视 ,差异无显著意义 (P >0 0 5 ) ;分别有 2 8%和 2 1 1%的患者获得黄斑中心近距离立体视 ,差异有显著意义(P <0 0 5 )。结论 老年性白内障摘除术后早期患者的双眼视觉未完全恢复 ;术前长期的视觉抑制 ,尤其是单眼抑制和术后的屈光参差可能是影响双眼视觉恢复的原因。
Objective To study the recovery of binocular vision and the risk factors that affect the recovery in the early post-operative stage of senile cataract patients. Methods Patients undergone extracapsular cataract extraction with intraocular lens implantation (ECCE group) or cataract phacoemulsification with intraocular lens implantation (PHACO group) were examined for their corrected visual acuity,refractive power,simultaneous perception, fusion, near and far-distance stereoacuity. Results Before operation, the visual acuity was worse in the ECCE group than that in the PHACO group (χ 2 =9.769, P <0.05);After operation, the visual acuity between ECCE group and PHACO group was not statistically significant (χ 2 =0.52 for operated eyes, P >0.05,χ 2 =3.52 for non-operated eyes, P >0.05) . The cylinder anisometropia in ECCE group was worse than the PHACO group(χ 2=12.496, P <0.01) . All patients obtained simultaneous perception and fusion sense. There was more or less far-distance stereoacuity 83.3% in ECCE group and 94.7% in PHACO group, which was no statistical significant (χ 2 =1.456, P >0.05). Foveal near stereoacuity was established in ECCE group (2.8%) and in PHACO group (21.1%), which were statistically significant(χ 2 =5.029, P <0.05). Conclusions There is incomplete recovery of binocular vision in the early post-operative stage of senile cataract patients. The vision depression, especially monocular depression before surgery and the anisometropia after operation may affect the recovery of binocular vision.
