正确理解及应用白内障微小切口超声乳化技术

Correct understanding and application of micro-incision cataract phacoemulsification technique

微切口白内障手术的优点在于其组织损伤更小,切口愈合更快;引起的手术源性角膜散光更小,对角膜的像差变化影响也变小。但随着手术切口逐渐减小,临床手术操作中会面临手术方式的微小改变,尤其是撕囊方式的改进、手术器械及超声乳化机器的更新、人工晶状体的选择、硬核白内障的处理等新问题。所以应该平衡手术切口与手术过程的安全性这一重要问题,依据病情及患者所采用的人工晶状体合理选择超声乳化方式。

Advantages of micro-incision cataract surgery include less tissue damage,faster wound healing,smaller surgery-induced astigmatism and smaller influence on corneal aberrations.But as the surgical incision becomes smaller and smaller,clinical surgical operations change correspondingly,such as improvement in capsulorhexis,update of surgical instruments and phacoemulsification machine,selection of IOL and handling with hard nuclear cataract,etc.So it is important to balance the surgical incisions and security of surgical procedures and to choose the technique of phacoemulsification based on the severity of cataract and the type of IOL.
