【摘要】：目的分析白内障小切口超声乳化联合角膜缘松解术矫正角膜散光的疗效。方法选取我院住院并行手术治疗的单纯性白内障患者30例(38眼),根据手术方式分为两组:A组行小切口白内障超声乳化联合角膜缘松解术(15例,18眼),B组行小切口白内障超声乳化术(15例,20眼)。观察两组患者术前、术后1周、3周、2个月的最佳矫正视力(best corrected visual acuity,BCVA)、角膜散光的变化,同时观察术后两组患者散光矫正量和术后并发症的情况。结果 A、B组患者术后1周、3周、2个月的BCVA与术前比较均显著提高,差异均有显著统计学意义(均为P0.01);术后随着时间的延长,BCVA逐渐提高,三个时间点间比较,差异均有显著统计学意义(均为P0.01);A组术后3周、2个月BCVA均明显高于B组,差异均有统计学意义(均为P0.05)。A、B组患者术后1周、3周、2个月的角膜散光值与术前比较均显著降低,差异均有显著统计学意义(均为P0.01);术后随着时间的延长,角膜散光值逐渐降低,三个时间点间比较,差异均有显著统计学意义(均为P0.01);A组术后1周、3周、2个月的角膜散光值明显低于B组,差异均有显著统计学意义(均为P0.01)。A组术后散光矫正量为(1.96±0.12)D,明显高于B组的(1.19±0.09)D,差异有显著统计学意义(P0.01)。A组和B组术后分别有1眼和2眼出现明显的角膜雾状混浊,术后3~4 d消失;A组和B组各有1眼出现眼部异物感,术后4~5 d消失。结论白内障小切口超声乳化联合角膜缘松解术可以明显减少术后患者的角膜散光,改善术后视力,安全性高。
[Abstract]:Objective to analyze the effect of small incision phacoemulsification combined with limbal lysis on corneal astigmatism. Methods Thirty patients (38 eyes) with simple cataract were divided into two groups: small incision phacoemulsification combined with corneal limbal lysis (15 cases, 18 eyes). Phacoemulsification of cataract (15 cases, 20 eyes). The best corrected visual acuity (best corrected visual acuity BCVA) and corneal astigmatism were observed before operation, 1 week and 2 months after operation, and the amount of astigmatism correction and postoperative complications were also observed. Results in group A, BCVA was significantly increased 1 week after operation and 2 months after operation (all P 0.01), BCVA was gradually increased with the extension of time, and the three time points were compared with each other. The BCVA in group A was significantly higher than that in group B at 3 weeks and 2 months after operation (all P0.05). The corneal astigmatism in group A was significantly lower than that in group B at 2 months. The corneal astigmatism value decreased gradually with the prolongation of time after operation, and the three time points were compared with each other. The corneal astigmatism in group A was significantly lower than that in group B at 1 week and 3 weeks after operation (all P0.01), and the value of corneal astigmatism in group A was significantly lower than that in group B at 2 months. The postoperative astigmatism correction in group A was (1.96 卤0.12) D, which was significantly higher than that in group B (1.19 卤0.09) D.The difference was statistically significant (P0.01) .There was a significant difference between group A (P0.01), group A (1 eye) and group B (2 eyes). One eye in group A and one in group B had ocular foreign body sensation on the 3rd and 4th day after operation, and disappeared on the 4th and 5th day after operation. Conclusion small incision phacoemulsification combined with limbal release can significantly reduce corneal astigmatism and improve postoperative visual acuity.
