摘　　要：目的评价25G经结膜无缝合玻璃体切除手术系统（25GSV）在白内障行超声乳化联合人工晶状体植入术后眼前段拥挤征治疗中的应用价值。方法采用25GSV对15例（15眼）白内障术后眼前段拥挤征行人工晶状体后囊切开＋前段玻璃体切除术，术后随访6—12个月，平均（8．0±1．5）个月，记录术后视力、眼压、前房深度，观察角膜、瞳孔、人工晶状体及并发症情况。结果所有手术均顺利完成。术后视力有不同程度提高，术前及术后1周、末次随访时平均最佳矫正视力分别为0．05±0．02、0．2±0．1、0．4±0．1，治疗前后相比，差异有统计学意义（P=0.00），术后1周、末次随访时平均眼压分别为（17．3±1．8）mmHg和（16．5±1．3）mmHg，较术前平均眼压（40．1±7．5）mmHg明显下降，差异有统计学意义（P=0．00）。术前及术后1周、末次随访时中央前房深度分别为（0．69±0．17）mm、（2．71±0．43）mm、（2．85±0．52）mm，治疗前后相比，差异有统计学意义（P=0．00）。所有病例术后角膜水肿消退，瞳孔圆，人工晶状体后囊中央均形成直径为3．0—4．0mm的圆孔，术中及术后均未见明显并发症发生。结论25G经结膜无缝合玻璃体切除能有效解除白内障术后眼前段拥挤征，手术创伤小，安全度高。Objective To investigate the application of 25-gauge transconjunctival sutureless vitrectomy system （25GTSV） on the treatment of crowded anterior segment（CAS） after phacoemulsification and intraocular lens implantation. Methods 15 cases（ 15 eyes） of CAS after cataract surgery were treated with posterior capsulotomy and anterior segment vitrectomy with 25GTSV. The follow-up periods were 6 - 12 months [ （ 8.0 ± 1.5 ） months ]. The visual acuity, intraoeular pressure （lOP） and the depth of anterior chamber were recorded, the condition of cornea, pupil, intraocular lens and complication were observed. Results All operations were successful. The visual acuity of all cases were improved in different degree after treat- ment. The best corrected visual acuity before treatment, 1 week after treatment and at the end of the followup period was （0.05 ±0.02）, （0.2 ±0. 1）and（0.4 ±0. 1） respectively. There were significant difference before and after treatment（t =0. 00,P =0.00）. The mean IOP 1 week after treatment and at the end of the follow-up period was （ 17.3 ± 1.8 ） mmHg and （ 16.5 ± 1.3 ） mmHg respectively. They were lower obviously than the mean IOP before surgery which was （40.1 ± 7.5 ） mmHg. There were significant difference between them （ t = 0. 0., P = 0.00 ）. The mean depth of anterior chamber before treatment, 1 week after treatment and at the end of the follow-up period was （0.69± 0.17 ）ram, （2.7 1 ±0.43 ）mm and（ 2.85 ± 0.52 ）mm respectively. There were significant difference before and after treatment（t = 0. 00 ,P = 0.00）. After surgery, the edema of cornea disappeared, the pupil is round and a round hyalomere with diameter of 3.0 ±4.0 mm was formed at the center of lens＇ posterior capsule in all eyes. No obvious complications were observed intra-operatively and postoperatively. Conclusion cataract surgery effectively and safely.
