激光全息立体视觉检查图在白内障超声乳化术后的应用

为研究白内障超声乳化并人工晶体植入术后患者的立体视觉功能，采用激光全息立体视觉检查图对80例白内障超声乳化并人工晶体植入术后患者进行了立体视视锐度的测定。其中男性43例，女性37例，年龄52-81岁。双眼手术62例，单眼手术18例。患者术后矫正视力均在0.4以上。在80例患者中，有近立体视觉者67例(83.7%)，无近立体视觉者13例（16.3%）。有远立体视觉者71例（88.8%），无远立体视觉者9例（11.2%）。立体视觉功能随年龄的增加而逐渐减弱，视力的高低与立体视觉功能密切相关。白内障摘除并人工晶体植入术后立体视觉功能会得到不同程度的恢复，远立体视觉功能较近立体视觉功能恢复好。立体视觉功能是评价白内障摘除并人工晶体植入手术疗效的一项重要指标。

APPLICATION OF LASER HOLOGRAPHIC STEREOVISION TEST CHART IN PATIENTS AFTER PHACOEMULSIFICATIONS

The purpose of this study was to investigate the function of stereo visual acuity in patients after phacoemulsifications and intraocular lens implantation. Mensuration of stereopsis with laser holographic stereovision test chart was done in 80 cases who had undergone phacoemulsifications and intraocular lens implantation. In this group, 43 patients were male, 37 were female .Ages of the patients were 52 to 81 years. Single eye operation was done in 18 cases, while both eye operation in 62 cases. The corrected vision was all over 0 4 in both eyes.In the 80 cases 67 (83 7%) had near stereopsis and 13 cases (16 3%)did not have; 71 cases (88 8%) had distance stereopsis and 9 cases (11 2%)did not have. Function of stereopsis weakens gradually following aging and is closely related with vision. The function of sterovision would recover to varying degrees after phacoemulsifications and intraocular lens implantation. Recovery of distance stereopsis was better than that of near stereopsis.The results of this study show that the status of stereopsis is an important index to evaluate the curative effect in patients after phacoemulsifications and intraocular lens implantation.
