硬质的棕或白色晶体核白内障一直是超声乳化手术的难题,两者的难点不同,前者核更硬,后者无红光反射使撕囊困难。为发挥超声乳化手术的优越性,本文对早期完成的43例手术分四组(棕核和白核,撕囊和开罐)进行分析和总结。发现超声乳化摘除硬核难度大,增加了并发症发生的可能性,并存在了更多的危险性。但手术一旦成功,术后次日视力即令人满意,0.5的占81.4%。并发症棕核组明显多于白核组(P<0.01)。而术后视力白核组明显比棕核组好(P<0.01)。提出要完成这类手术,一定要有娴熟的技巧,掌握环形前囊孔的制作,缩短乳化时间,降低并发症的发生率,提高手术成功率。
Hard brown or white crystal nucleus cataract has always been a difficult problem for phacoemulsification. The difference between the two is that the former is harder, and the latter is free from red reflex, making capsulorhexis difficult. In order to give full play to the superiority of phacoemulsification, 43 cases of early surgery were divided into four groups (brown nucleus and white nucleus, capsulorhexis and can opener) to analyze and summarize. Found that phacoemulsification hard core removal, increasing the possibility of complications, and there is more danger. However, once the operation was successful, the visual acuity was satisfactory on the next day after operation, with 0.5% accounting for 81.4%. Complication of brown nucleus group was significantly more than white nucleus group (P <0.01). The postoperative visual acuity white nucleus group was significantly better than the brown nucleus group (P <0.01). Proposed to complete this type of surgery, there must be skilled techniques to master the production of annular anterior capsule hole, shorten the emulsification time, reduce the incidence of complications and improve the success rate of surgery.
