摘　　要：目的探讨手法小切口白内障手术中出现虹膜根部断离的原因和处理方法。方法手法小切口白内障手术中出现虹膜根部断离者22例(22眼)。采用显微手术修复,其中21眼进行Ⅰ期手术,1眼进行Ⅱ期手术。结果22眼术中出现虹膜根部断离的原因,与作巩膜隧道切口有关者12眼(54.54%),与娩核有关者5眼(22.73%),与抽吸皮质有关者3眼(13.64%),与人工晶状体植入有关者2眼(9.09%)。22眼均修复良好,手术顺利。术后视力≥0.5者19眼(86.36%),≤0.2者3眼(13.64%)。均未出现单眼复视及其它严重并发症。结论术中操作不当是造成手法小切口白内障手术中虹膜根部断离的主要原因,而提高手术技巧、及时准确的处理是关键。Objective To discuss the causes and the management of iridodiastasis occurred during the minor incision extraction of cataract. Methods Twenty two patients （22 eyes） who had iridodiastasis due to the minor incision extraction of cataract, underwent microscopic repair. Among them, 21 eyes had primary repair, and one eye had secondary repair. Results The causes of iridodiastasis were discussed, 12 cases were related to the tunnel incision of the sclera （54.55%）, 5 eyes were related to the extraction of the nuclear （22.73%）, 3 eyes were related to the suction of substantia corticalis （13.64%）, 2 eyes were related to the implantation of artificial lens （9.09 % ）. The repairs of the 22 eyes were satisfactory. In 19 patients, VA was ≥ 2.5 （ 86.36 % ）, in 3 patients, VA was ≤ 0.2 （ 13.64 % ）. Monocular diplopia and other severe complications were not found. Conclusions Extreme caution always needs to be exercised to ensure no improper operation takes place during the minor incision extraction of cataract. Otherwise this may later cause iridodiastasis.
