摘要
目的探讨在小切口非超声乳化白内障摘出联合人工晶状体植入术中,利用注射器针头实施囊袋内吸附劈核法的可行性及疗效。方法对365例(458眼)晶状体核硬度为Ⅱ-Ⅳ级的老年性白内障患者,实施小切口非超声乳化白内障摘出术,其中235例297眼采用晶状体圈匙前房内劈核法,即为前房内劈核组,130例161眼采用普通注射器针头囊袋内劈核法,即为囊袋内劈核组。术后随访1～7d,观察并比较两组患者术后视力恢复及术中、术后并发症情况。结果术后第1天,前房内劈核组视力为0.40±0.13,其中≥0.3者233眼(78.5%),囊袋内劈核组为0.42±0.13,其中≥0.3者132眼(82.0%);术后第7天复诊的307眼中,前房内劈核组188眼,视力为0.61±0.14,其中≥0.5者157眼(83.5%),囊袋内劈核组119眼,视力为0.62±0.15,其中≥0.5者101眼(84.9%),两组不同时间点视力相比差异均无统计学意义(均为P>0.05)。术中发生后囊膜破裂者前房内劈核组4眼,囊袋内劈核组3眼,两组劈核成功率差异无统计学意义(P>0.05)。术后瞳孔非正圆及角膜水肿者,前房内劈核组分别为12眼、78眼,囊袋内劈核组分别为9眼、31眼。结论利用注射器针头实施囊袋内吸核和劈核方法具有操作简单、手术成功率高、术后恢复好、手术成本低等优点,易于在基层医院推广实施。
Objective To explore the feasibility and clinical effect of microinci- sion cataract surgery and intraocuiar lens （IOL） implantation by using the injector tip to perform chop nucleus in the capsular bag. Methods Three hundreds and sixty-five patients （458 eyes） with the lens nucleus grading from level II to level IV performed microincision cataract surgery,235 cases （297 eyes） used the chop technique with lens loop-pad in the anterior chamber （group A）, whereas 130 cases （ 161 eyes） used the method of chop nucleus with injector tip in the capsular bag （ group B）. The follow-up time was from 1 day to 7 days, the postoperative visual acuity, intraoperative and post- operative complications in group A and B were observed and compared. Results At 1 day after operation,the visual acuity of group A and B were 0.40 ±0.13 and 0.42 ±0.13 in which more than 0.3 in 233 eyes （78.5%） and 132 eyes （82.0%） ,respectively. At 7 days after operation, the follow-up eyes in group A and B were 188 eyes and 119 eyes, the visual acuity of group A and B were 0.61 ± 0.14 and 0.62 ± 0.15, in which more than 0.5 in 157 eyes （83.5%） and 101 eyes （84.9%） ,there was no statistical difference in visual acuity between each postoperative time point （ both P 〉 0.05 ）. The posterior capsule rupture occurred in 4 eyes of group A and 3 eyes of group B, there was no statistical difference （P 〉 0.05 ）. The postop- erative unround pupil and corneal edema appeared in 12 eyes and 78 eyes of group A,9 eyes and 31 eyes of group B. Conclusion Using the method of chop nucleus with injector tip in the capsular bag is easy to implement with low cost,high successful rate and efficient patient recovery. It is an appropriate technique to treat eyes with mature cataract in the primary hospitals.
