目的分析4mm透明角膜切口超声乳化联合折叠式人工晶状体植入术后的屈光状态和屈光改变稳定时间。设计前瞻性病例非对照研究。研究对象96例白内障患者。方法对96例(111眼)白内障患者行4mm透明角膜切口白内障超声乳化吸除术联合折叠式人工晶状体植入术。对全部术眼分别应用显然验光法和角膜曲率法观察术后1周、1、2、3个月球镜和散光度数的变化。主要指标屈光度。结果术后1周、1、2、3个月全部术眼球镜分别为(-1．02±0．95)D,(-0．92±0．98)D,(-0．89±0．96)D．(- 0．87±0．93)D；眼轴＜25mm者球镜分别为(-0．80±0．74)D,(-0．70±0．79)D,(-0．67±0．76)D,(-0．64±0．71)D；眼轴≥25mm者球镜分别为(-1．84±1．20)D,(-1．72±1．19)D,(-1．73±1．15)D,(-1．72±1．15)D。全部术眼和眼轴＜25mm者术后1周与1个月比较屈光度数间差异无统计学意义(P=0．61．P=0．89),眼轴25mm者术后1个月与2个月比较屈光度数间差异无统计学意义(P=0．90)。各时段全部术眼手术性散光为(1．64±1．25)D,(1．61±1．31)D,(1．58±1．29)D,(1．57±1．25)D。全部术眼、眼轴＜25mm者、眼轴≥25mm者术后1周与术前相比散光差异无统计学意义(P均＞0．05)。结论4mm透明角膜切口白内障超声乳化联合人工晶状体植入手术,不论眼轴＜25mm还是≥25mm,术后1个月屈光达到稳定,可以配镜矫正。(眼科,2006,15：338-340)
Objective To analyze the refractive status and refractive stability of 4mm clear corneal incision phacoemulsification combined with foldable intraocular lens implantation. Design prospective case-control study. 96 cases of cataract patients. Methods 96 cases (111 eyes) of cataract patients underwent 4mm clear corneal incision cataract phacoemulsification combined with foldable intraocular lens implantation. Apparent optometry and corneal curvature were used to observe the changes of spherical and astigmatism degree at 1 week, 1, 2, and 3 months after operation. The main index diopter. Results The total spherical ophthalmoscope was (-1.02 ± 0.95) D, (- 0.92 ± 0.98) D, (-0.89 ± 0) .96) D. (- 0.87 ± 0.93) D, respectively; spherical lenses with axial length less than 25 mm were (-0.80 ± 0.74) D, (-0.70 ± 0.79) D, ± 0.76) D, (-0.64 ± 0.71) D, respectively; spherical lenses with axial length ≥25 mm were (-1.84 ± 1.20) D, (-1.72 ± 1.19) D, (-1.73 ± 1.15) D, (-1.72 ± 1.15) D. There was no significant difference in diopters between one week and one month postoperatively (P = 0.61, P = 0.89), one month after operation and one month after operation There was no significant difference between two groups in comparison of refraction (P = 0.90). The operative astigmatism was (1.64 ± 1.25) D, (1.61 ± 1.31) D, (1.58 ± 1.29) D, (1.57 ± 1.25) ) D. There was no significant difference in astigmatism between preoperative and postoperative one week after operation in all eyes with axial length <25mm and axial length ≥ 25mm (all P> 0.05). Conclusion 4mm clear corneal incision cataract phacoemulsification combined with intraocular lens implantation surgery, regardless of the axial length of <25mm or ≥ 25mm, refraction after 1 month to reach a stable, you can glasses correction.
