目的观察逐块吸除法白内障超声乳化人工晶体植入术的治疗效果。方法老年白内障78例89眼,根据晶体核硬度进行分组,晶体核I-III级为软核组,有41例47眼;晶体核IV级为硬核组,有37例42眼,两组均采用逐块吸除法白内障超声乳化人工晶体植入术,术后同一方法抗炎,观察术后视力及角膜水肿情况。结果软核组平均视力在术后1、3、30 d分别为0.64±0.21、0.73±0.21、0.81±0.23硬核组平均视力在术后1、3、30 d分别为0.59±0.23、0.71±0.23、0.80±0.23。2组视力数据差异无统计学意义(P>0.05)。软核组角膜水肿例数在术后1、3、7 d分别为8眼(17.02%)、3眼(6.38%)、0眼,硬核组角膜水肿例数在术后1、3、7 d分别为11眼(26.19%)、4眼(9.52%)、0眼。2组角膜水肿发生率差异无统计学意义(P>0.05)。结论逐块吸除法白内障超声乳化人工晶体植入术既适用于软核白内障也适用于硬核白内障,是一种安全、有效的手术方法。
Objective To observe the therapeutic effect of phacoemulsification and intraocular lens implantation by block-by-block aspiration. Methods Seventy-nine patients (89 eyes) with senile cataract were divided into groups according to the hardness of the crystal nucleus. The I-III crystal nucleus was soft-core group and 41 cases were 47 eyes. The IV nucleus of the crystal nucleus was in the hard nucleus group and the 37 cases in 42 eyes. Using block-by-block suction cataract phacoemulsification with intraocular lens implantation, the same method after anti-inflammatory, postoperative visual acuity and corneal edema. Results The mean visual acuity of the soft nucleus group was 0.64 ± 0.21, 0.73 ± 0.21 and 0.81 ± 0.23 respectively at 1, 3 and 30 days after operation. The average visual acuity of the hard nucleus group was 0.59 ± 0.23 and 0.71 ± 1.23 There was no significant difference in visual acuity data between 0.23,0.80 ± 0.23.2 group (P> 0.05). The numbers of corneal edema in the soft nucleus group were 8 eyes (17.02%), 3 eyes (6.38%) and 0 eyes respectively on the 1st, 3rd, 7th day after operation, d were 11 eyes (26.19%), 4 eyes (9.52%), 0 eyes respectively. There was no significant difference in the incidence of corneal edema between the two groups (P> 0.05). Conclusions Block by block aspiration cataract phacoemulsification with intraocular lens implantation is not only suitable for soft cataract but also for hard cataract. It is a safe and effective surgical method.
