Abstract
Objective To observe the clinical effect of 3 mm small incision of manual chopping nucleus tech‐nique in treating grade Ⅳ and Ⅴhard nucleus cataract .Methods 221 cataract patients (242 eyes) from January 2013 to December 2014 in the ophthalmology department of Chongqing Liangping People′s Hospital were selected and di‐vided into the experimental group and the control group .The experimental group(143 cases ,157 eyes including 119 eyes of grade Ⅳ hardness nucleus and 38 eyes of grade Ⅴ hardness nucleus) was performed 3 mm ball conjunctiva corneoscleral limbus tunnel type incision ,the followed soft part of hard nucleus was chopped firstly ,then the center of hard nucleus was rotated or divided into pieces for removing ,lastly the foldable intraocular lens were implanted .The control group(78 cases ,85 eyes including 61 eyes of grade Ⅳ hardness nucleus ,and 24 eyes of grade Ⅴhardness nu‐cleus) was performed the central 4 mm of manual chopping nucleus pulposus ,then the foldable intraocular lens was implanted .Postoperative complications and postoperative visual acuity were compared between the two groups .Re‐sults Posterior capsule rupture in 2 eyes (1 .27% ) and corneal edema in 29 eyes (18 .5% ) occurred in the experi‐mental group ,which in the control group were 3 eyes (3 .5% ) and 34 eyes (40% ) respectively ,there were statistical‐ly significant difference in two indexes above between the both groups(P<0 .05) .In the experimental group ,the vis‐ual acuity at postoperative 1 week was better than 0 .5 in 106 eyes (67 .5% ) in the experimental group ,and which af‐ter 1‐month re‐examination was better than 0 .5 or equal to 0 .5 in 139 eyes (88 .5% ) ,but which at postoperative 1 week was in 46 eyes(54 .1% ) and which after 1‐month re‐examination was in 69 eyes(81 .2% ) in the control group , the There differences between two groups were statistically significant (P<0 .05) .Conclusion The manual chopping nucleus for grade Ⅳ - Ⅴ hard nucleus can significantly reduce the intraoperative and postoperative complications ,and can improve the operation effect .关键词
