    摘要:

    目的:探讨小瞳孔下超声乳化白内障吸除及人工晶状体植入术的手术技巧和临床效果。

    方法:临床确诊的小瞳孔白内障患者35例43眼,采用黏弹剂钝性分离或瞳孔缘部虹膜拉开等方法扩大瞳孔,行环形撕囊、双手原位超声乳化白内障吸除及折叠式人工晶状体囊袋内植入手术。

    结果:术后随访5~12mo,视力≥0.5者26眼(60%),术后视力提高38眼(88%),所有患者的瞳孔均保持圆形或近圆形,部分患者瞳孔直径较术前变大,无人工晶状体偏位。手术并发症主要有角膜水肿、前房纤维素性渗出或后囊膜破裂等。

    结论:小瞳孔下白内障的超声乳化手术复杂,熟练的掌握手术技巧及合理的手术时机,同样可以取得良好的手术效果。

    Abstract:

    AIM: To investigate the surgical technique and clinical efficacy of phacoemulsification combined with intraocular lens implantation in cataract with microcoria.

    METHODS: In 35 cases(43 eyes)of microcoria cataract, pupilloplasty were aided by viscoelastics or pulling from papillary collar. Continuous curvilinear capsulorhexis, phacoemulsification, and intraocular lens implantation were performed in all of the patients.

    RESULTS: During the follow up of 5 to 12 months, 38 eyes(88%)got improved visual acuity, and it's better than 0.5 in 26 eyes(60%). The pupils of all patients remained circular or close circular with lightly expanded in some patients, without dislocation of intraocular lens. Main complications included corneal edema, fibrous exudates in anterior chamber, and rupture of posterior capsule.

    CONCLUSION: Despite the complexity,phaco-emulsification is still an efficacy technique for treatment of cataract with microcoria.
