方法：选择本院门诊和住院白内障患者500眼，采用术前睑板腺按摩联合结膜囊稀释碘伏液冲洗后行结膜囊细菌学临床观察。

结果：我科对500眼白内障患者术前采用睑板腺按摩联合结膜囊稀释碘伏液冲洗结膜囊后随机性结膜囊细菌学培养，结膜囊混合液残留液取样培养基本无细菌生长繁殖，500眼白内障患者均未发生细菌性眼内炎和术后眼前房炎症性反应。

结论：白内障术前采用睑板腺按摩使睑板腺分泌物和细菌溢出，用稀释碘伏液冲洗结膜囊，不仅可冲洗结膜囊细菌和睑板腺按摩后溢出睑板腺分泌物和细菌且可杀死细菌，保证了手术眼环境的无菌眼环境，防止细菌性眼内炎发生，对预防细菌性眼内炎意义重大，其方法简单、易行、经济。

METHODS: Totally 500 eyes in our hospital outpatient and hospitalization cataract patients were tested with the clinical observation of bacteriology on meibomian gland massage couple with dilute iodine volts liquid flushing the conjunctival sac before cataract surgery.

RESULTS: All eyes of cataract which received meibomian gland massage with dilute iodine volts liquid flushing conjunctival sac were carried out randomly the bacteriology training, the sample of conjunctival sac mixture residue fluid had no bacteria growth, no case of cataract patient took place the bacterial endophthalmitis and postoperative anterior chamber of inflammatory reaction.

CONCLUSION: Meibomian gland massage makes the meibomian gland secretions and bacteria overflow, flushing conjunctival sac with dilute iodine volts liquid not only can wash conjunctival sac, meibomian gland secretions and bacteria but also can kill bacteria, to ensure the germ-free environment during the eye operation and prevention of bacterial endophthalmitis, which is of great significance to prevention of bacterial endophthalmitis, the method is simple, easy and economic.
