过熟期白内障超声乳化术和囊外摘出术的手术效果比较

Comparison of Surgical Efficacy between Phacoemulsification and Extracapsular Extraction in the Treatment of Hypermature Cataract

目的:探讨过熟期白内障超声乳化术和囊外摘出术的效果。方法:选取过熟期白内障患者261例,随机分为两组,其中A组124例,B组137例,两组差异不明显,无统计学意义。A组患者给予超声乳化术联合人工晶体植入术;B组患者给予囊外摘出术联合人工晶体植入术。对两组患者的术后视力及角膜水肿情况进行比较。结果:术后第一天A组患者视力<0.05者和≥0.03者均明显高于B组;发生角膜水肿者A组明显多于B组。上述比较两组差异明显,有统计学意义(P<0.05)。结论:对于过熟期白内障进行手术治疗时,应完善术前相关检查,充分考虑角膜内皮健康状况以及患者对视力的期望值等谨慎选择手术方式。

Objective：To compare the clinical efficacy of phacoemulsification and extracapsular extraction in the treatment of hypermature cataract. Methods： 261 eases of hypermature cataract were selected and randomized into the Group A （124 cases） and Group B （137 eases）; there was no statistical difference between the two groups. Group A was treated with phaeoemulsification in combination with intraoeular lens implantation and Group B was treated with extraeapsular extraction in combination with intraoeular lens implantation. Postoperative vision and corneal edema rate were compared between the two groups. Results：The first day after operation,there were significantly more eases with vision 〈0.05 or 30.03 in Group A than in Group B, and there were significantly more eases with corneal edema in Group A than in Group B; there was statistical difference between the two groups （P〈0.05）. Conclusion：Preoperative examinations were essential for patients with hypermature; corneal endothelial conditions and the patient＇s expectations in vision must be taken into consideration before a surgical method is selected.
