目的比较过熟期白内障超声乳化术和囊外摘出术的手术效果、术中和术后并发症,并探讨其手术技巧。方法将139例(184眼)过熟期白内障随机分成两组,A组70例(93眼)行晶状体超声乳化术,B组69例(91眼)行白内障囊外摘出术,均联合人工晶状体植入术。于术后1d对两组裸眼视力、术中及术后并发症进行比较。结果术后1d裸眼视力0.05~0.25者B组明显高于A组(P<0.05)。术后1d裸眼视力<0.05及≥0.3者B组明显低于A组(P<0.05)。术中晶状体核掉入玻璃体腔、玻璃体脱出眼数A组明显高于B组(P<0.05)。术后角膜水肿眼数A组明显高于B组(P<0.05)。结论过熟期白内障行白内障囊外摘出术较超声乳化术更具有安全性。
Objective To compare the surgical effects, intraoperative and postoperative complications of phacoemulsification and extracapsular cataract extraction in over-mature period and to explore the surgical techniques. Methods 139 cases (184 eyes) of over-mature cataract were randomly divided into two groups. Group A (70 eyes) received phacoemulsification and group B (69 eyes) (91 eyes) underwent extracapsular cataract extraction combined with intraocular lens Implantation. Visual acuity, intraoperative and postoperative complications were compared between the two groups at 1 day after operation. Results Visual acuity of 0.05-0.25 at 1 day after operation was significantly higher in group B than in group A (P <0.05). The naked eye visual acuity <0.05 and ≥0.3 on day 1 postoperatively in group B was significantly lower than that in group A (P <0.05). Intraocular lens nucleus dropped into the vitreous cavity, vitreous prolapse group A was significantly higher than the B group (P <0.05). The number of corneal edema in group A was significantly higher than that in group B (P <0.05). Conclusion Cataract extracapsular cataract extraocular extracapsular cataract surgery is more safe than phacoemulsification.
