目的：探讨透明角膜切口白内障超声乳化联合巩膜扣带术治疗白内障合并视网膜脱离的临床疗效。方法：对12例白内障合并视网膜脱离的患者采用透明角膜切口白内障超声乳化联合人工晶体植入及联合巩膜扣带术。结果：12例患者视网膜均复位且视力提高，随访2～18月，有2例发生后发障，行YAG激光治疗，未见视网膜复发性脱离。结论：对一些白内障合并视网膜脱离的患者可进行透明角膜切口白内障超声乳化联合人工晶体植入及联合巩膜扣带术，这样既扫除了视网膜脱离复位术中及术后的观察障碍，又不耽误视网膜脱离的治疗，还可以术后增加视力。 相似文献

<正> 白内障手术后其裸眼视力不足0.1,必须戴眼镜或角膜镜才能提高。如果不戴镜矫正,久之则造成弱视或斜视,尤其是青少年。若在白内障术后植入人工晶体,其视力则明显提高,并避免戴镜之不足。我院眼科自1986.2—1988.9.收治14例白内障,年令在5—16岁。 相似文献

目的:探讨应用LASEK治疗中、高度近视疗效。方法:激光角膜上皮瓣下磨镶术(lsaer epithelid keretmileusis,LASEK)原理是通过在角膜上皮分离出一个角膜瓣,然后用激光进行切削,最后角膜上皮瓣复位,并配戴角膜接触镜3d。本文对在我院接受LASEK治疗的中、高度近视患者21例(42眼)进行随访,年龄22.3±4.0岁,平均术前等球镜为-8.57D±2.15D(-5.00D~-11.0D),平均角膜厚度496μm(462~530μm),平均随访时间6.5月;术后常规观察视力、屈光度、角膜混浊程度、眼压、角膜地形图等情况。结果:1.术后角膜上皮混浊haze采用Fantes标准分级,21例中19例术后3个月时角膜上皮下混浊为0级,2例术后3个月时角膜上皮下混浊为0.5级,但无屈光回退。2.术后屈光度及裸眼视力均在6个月内趋于稳定,术后6个月裸眼视力达到和超过矫正视力的20例,占总例数的95.2%。1例比术前最佳矫正视力下降二行,占总例数的4.8%。3.术后屈光状态:术后10d时平均屈光度为 0.52±0.87D,术后3个月为 0.37±1.21D,术后6个月为 0.12±0.87D者20例,占95.2%。4.本组观察:角膜上皮瓣的厚度有差异,上皮瓣的厚薄与是否配戴接触镜有关,与配戴接触镜时间长短有关,配戴10年以上接触镜者角膜上皮明显变薄。结论:LASEK治疗中、高度近视疗效确切、安全。高度近视术后haze发病率低,无明显屈光回退发生,本组病例较少,有待于更多样本、更长时间临床观察和随访。 相似文献

The present study examined the developmental change in number and length acuities and their respective relationship with achievement in various domains of mathematics in second vs. fourth graders. Length acuity was measured with a comparison task, in which participants were asked to choose the longer between a pair of lines. Number acuity was measured with a comparison task, in which the participants were asked to choose the more numerous between a pair of dot arrays. Within each grade, length acuity was more precise compared to number acuity. Number acuity was higher in fourth compared to second grade, but length acuity did not differ between grades manifesting a ceiling effect. In second grade, only length acuity was correlated with overall math achievement, especially Geometry and Arithmetic. In fourth grade, only number acuity was correlated with overall mathematical achievement, especially Number Concept and Applied Problems. Taken together, the present study demonstrates that the relationship between magnitude acuities and math achievement dynamically change over the course of elementary school years and that the strength of this relationship may depend on the type of magnitude and the domain of mathematics. 相似文献

Objective: To analyze the effectiveness and safety of corneal relaxing incisions (CRI) in correcting keratometric astigmatism during cataract surgery. Methods: A prospective study of two groups: control group and treatment group. A treatment group included 25 eyes of 25 patients who had combined clear corneal phacoemulsification, IOL implantation and CRI. A control group included 25 eyes of 25 patients who had clear corneal phacoemulsification and IOL implantation.Postoperative keratometric astigmatism was measured at 1 week, 1 month, 3 months and 6 months. Results: CRI significantly decreased keratometric astigmatism in patients with preexisting astigmatism compared with astigmatic changes in the control group. In eyes with CRI, the mean keratometric astigmatism was 0.29±0.17 D (range 0 to 0.5 D) at 1 week, 0.41±0.21 D (range 0 to 0.82 D) at 1 month, respectively reduced by 2.42 D and 2.30 D at 1 week and 1 month postoperatively (P=0.000, P=0.000), and postoperative astigmatism was stable until 6 months follow-up. The keratometric astigmatism of all patients decreased to less than 1.00 D postoperatively. Conclusions: CRI is a practical, simple, safe and effective method to reduce preexisting astigmatism during cataract surgery. A modified nomogram is proposed. The long-term effect of CRI should be investigated. 相似文献

Long-term comparison of full-bed deep anterior lamellar keratoplasty and penetrating keratoplasty in treating keratoconus 总被引：2，自引：2，他引：0
Yong-ming Zhang Shuang-qing Wu Yu-feng Yao 《Journal of Zhejiang University. Science. B》2013,14(5):438-450
Objective
To compare postoperative outcomes of full-bed deep anterior lamellar keratoplasty (DALK) with penetrating keratoplasty (PK) in treating keratoconus.Methods
Seventy-five eyes of 64 patients who received full-bed DALK and 52 eyes of 51 patients who received PK between June 2000 and August 2010 were included in this retrospective study. Full-bed DALK was performed using Yao’s hooking-detaching technique. PK was performed using a standard technique. Intraoperative and postoperative complications, visual acuity, rejection, graft survival, endothelial cell density, corneal sensation recovery, and re-innervation were compared between the two groups.Results
A best correct visual acuity of 0.5 or better was achieved in 90.7% of eyes after full-bed DALK and in 92.3% of eyes after PK (P=0.75). By the fifth postoperative year, graft endothelial cell loss reached 34.6% in the PK group vs. 13.9% in the full-bed DALK group (P<0.001). There were no statistical differences in corneal sensitivity recovery or corneal re-innervation between the groups (P>0.05). Intraoperative microperforation occurred in seven out of 75 (9.3%) eyes with a temporally postoperative double anterior chamber in two eyes in the full-bed DALK group. Postoperative complications in the PK vs. the full-bed DALK groups respectively were: rejection (7.7% vs. 0%, P=0.015), high intraocular pressure (IOP) (46.2% vs. 1.3%, P<0.001), secondary glaucoma (9.6% vs. 0%, P=0.006), complicated cataract (19.2% vs. 0%, P<0.001), and wound dehiscence (9.6% vs. 0%, P=0.006).Conclusions
Both full-bed DALK and PK can offer long-term satisfactory visual outcomes for keratoconus. Graft rejection, secondary glaucoma, complicated cataracts, and constant endothelial cell loss were observed in eyes only after PK. 相似文献19.

研究目的：创新要点：研究方法：观察采用冰冻保存供体的周边深板层角膜移植治疗Terrien’s角膜变性（TMD）的临床疗效,探讨TMD的最佳手术治疗方式。供体角膜为冰冻保存,其中部分为中央角膜移植术后剩余的角巩膜环,并改进传统的手术方法。采用周边深板层角膜移植,既充分利用和节约供体,避免排斥反应,又简化了手术操作过程,有效地恢复了眼球完整性和提高术后视力。研究对象为1998年6月至2012年12月期间在浙江大学医学院附属邵逸夫医院眼科中心进行周边深板层角膜移植术的27例TMD病人的31只眼。根据病变范围和大小,分别进行环形深板层角膜移植和D形深板层角膜移植。所有植片均于-20℃冰冻保存,冰冻保存的角巩膜环植片用于环形深板层角膜移植,冰冻保存的整个眼球用于D形深板层角膜移植。对所有术眼的病例资料、视频及影像学检查进行回顾性分析,记录并总结患者的一般情况、术中表现、术后角膜结构的变化、屈光及视力的变化及术后并发症等。重要结论：采用冰冻保存供体的周边深板层角膜移植治疗TMD可以有效地恢复角膜结构的完整性且能长期维持（图3和4）。术后随访过程未发现免疫排斥反应,环形深板层角膜移植术后视力较前明显提高,而3例（100％）D形深板层角膜移植术后散光及视力均不提高（表1和2）。术前炎症及术中穿孔并不影响术后最终结果。 相似文献
