摘　　要：目的:探讨角膜颞侧切口行超声乳化白内障吸出联合人工晶状体植入术对白内障的治疗效果及对眼压、泪膜稳定性的影响。方法:回顾性分析2014-03/2015-12在我院接受治疗的白内障患者的临床资料,并根据其手术切口位置分为角膜颞侧切口组和上方透明角膜切口组。观察两组患者手术一般情况和并发症发生率,比较两组患者手术前后眼压、视力、屈光度和泪膜破裂时间的差异。结果:两组患者手术时间和术后疼痛得分比较无统计学意义(P>0.05);两组患者术前眼压和视力比较无统计学意义(P>0.05),术后7d,两组患者的眼压均较术前降低、视力较术前增高,且角膜颞侧切口组变化更明显,差异有统计学意义(P<0.05);两组患者术前屈光度、泪膜破裂时间比较无统计学意义(P>0.05),术后1mo,两组患者的屈光度较手术前增高,泪膜破裂时间较手术前降低,且角膜颞侧切口组变化更明显,差异有统计学意义(P<0.05),两组患者前房积血、角膜水肿和前房渗出发生率无明显差别。结论:角膜颞侧切口行超声乳化白内障吸出联合人工晶状体植入对白内障有较好的治疗效果,能有效改善患者眼压与泪膜稳定性,促进术后机体康复。AIM：To investigate therapeutic effect of lateral temporal corneal incision phacoemulsification combined with intraocular lens（IOL） on cataract and its effect on intraocular pressure（IOP） and tear film.METHODS：The clinical data of patients with cataract who received treatment in our hospital from March 2014 to December 2015 were retrospectively analyzed.According to the location of the incision,they were divided into temporal corneal incision group and upper corneal incision group.We observed the incidence of complications of the two groups,compared the intraocular pressure,visual acuity,refraction and tear film break-up time of the two groups before and after surgery.RESULTS：The operation time and postoperative pain score of the two groups had no significant difference（P〉0.05）.The IOP and visual acuity between the two groups before operation had no significant difference（P〉0.05）.At the intraocular pressure of the two groups was lower than that before operation,and the visual acuity was higher than before operation,and the changes of the anterior lateral incision group were more obvious（P〉0.05）.The diopter,tear film break-up time of the two groups had no significant difference.At 1mo after operation,the diopter of the two groups all increased,tear film break-up time was lower than before the surgery and temporal corneal incision group changes more obvious（P〈0.05）.There was no significant difference in the incidence of anterior chamber,corneal edema and anterior chamber exudation in the two groups of patients with corneal incision group.CONCLUSION：The temporal corneal incision phacoemulsification combined with intraocular lens implantation has a good therapeutic effect on cataract patients,can effectively improve the intraocular pressure and tear film stability,improve eye function,promote the recovery of the body after surgery.
