外伤性白内障人工晶体植入后双眼单视的探讨

An approach to the binocular vision of traumatic cataract after intraocular lens implantation

目的探讨单眼白内障摘除后植入后房型人工晶体能否恢复双眼单视及立体视。方法将３６例外伤性白内障摘除后分一期和二期植入后房型人工晶体。术后分别观察其裸眼及矫正视力、双眼屈光状态，并用同视机、线状镜、障碍阅读及Ｔｉｔｍｕｓ立体视觉检查图检查双眼视及立体视的状态。结果３６例术后视力均显著提高，３个月后矫正视力４．９５以上者２４例（６６．７％），４．８以上者３０例（８３．３％）。其中２６例检查双眼视及立体视，２１例恢复良好。结论单眼白内障尤其是儿童，应提倡早期植入人工晶体，以促进双眼单视及立体视觉的恢复和发育。

Objictive To explore the recovery of binocular vision and stereoacuity of monocular cataract extraction after posterior chamber intraocular lens (IOL) implantation.Methods After extrac tion of traumatic cataract,primary or secondary posterior chamber IOL implantation was performed on 36 cases.The naked vision,corrected vision and binocular dioptric state were observed pre and postoperatively.Synoptophore,Bogolini striated glasses,barred reading and Tiemus stereoscopic vision picture were applied.Results The visual acuities of 36 cases were significantly improved postoperatively,the corrected visual acuities of 24 cases (66.7%) were over 4.95 and 30 cases were over 4.8 after threemonths.The binocular and stereoscopic vision of 21 cases was recovered well. Conclusion IOL implan tation should be per for medearly after extraction of monocular cataract in order to improve the recovery and development of binocular vision and stereoacuity,particularly in children.
