摘要:
目的　观察在合并低度角膜散光的白内障患者中行陡峭轴角膜切口和颞侧角膜切口超声乳化术后角膜散光和视力的变化。方法　将我院收治的合并角膜散光≤0.50 D的年龄相关性白内障患者共60例(60眼)根据术中切口不同分成A、B两组。A组30例行陡峭轴切口，B组30例行颞侧角膜切口。观察术前及术后1周、1个月、3个月裸眼视力（uncorrected visual acuity，UCVA)、最佳矫正视力（best corrected visual acuity，BCVA)、角膜散光、术源性散光(surgically induced astigmatism，SIA)，并进行统计学分析。结果　术后1个月、3个月，A组UCVA均优于B组（均为P＜0.05）；两组术后各时间点BCVA比较差异均无统计学意义（均为P＞0.05），但均较术前明显提高（均为P<0.05）。A组UCVA术后3个月优于术后1个月、术后1个月优于术后1周，差异均有统计学意义 (均为P＜0.05)。A组BCVA于术后1个月基本稳定。术后1周、1个月、3个月，A组角膜散光均低于B组（均为P＜0.05）。A组角膜散光术后3个月为（0.26±0.20）D，略低于术前的（0.32±0.13）D，但差异无统计学意义（P=0.42）。B组术后3个月角膜散光为（0.62±0.45）D，高于术前的（0.23±0.17）D，差异有统计学意义（P<0.05）。术后1周A组 SIA为（1.28±0.63）D，高于B组的（0.77±0.39）D，差异有统计学意义（P=0.01）。术后1个月、3个月两组SIA比较差异均无统计学意义（均为P＞0.05）。结论　术前角膜散光≤0.50 D的白内障患者行白内障超声乳化手术时，选择陡峭轴切口并不能矫正术前角膜散光，但能减小术后总角膜散光，且可以有效提高术后UCVA，术后效果优于颞侧角膜切口。
Abstract:
Objective　To observe the corneal astigmatism and vision changes in cataract patients with preoperative corneal astigmatism less than 0.50 D after phacoemulsification that using steep axis corneal incision and temporal corneal incision.Methods　A total of 60 cataract patients (60 eyes) who with preoperative corneal astigmatism under or equal 0.50 D in our hospital were collected,then divided into group A and group B according to the incision,30 patients (30 eyes) in group A undergoing steep axis corneal incision and 30 patients (30 eyes) in group B undergoing temporal corneal incision.The uncorrected visual acuity (UCVA),best corrected visual acuity (BCVA),corneal astigmatism and surgically induced astigmatism (SIA) were observed preoperatively and at 1 week,1 month,3 months postoperatively,and data were statistically analyzed.Results　UCVA was better in group A than in group B at 1 month,3 months postoperatively (all P<0.05).There were no statistically significant differences in BCVA between group A and group B at each time-point after surgery (all P<0.05),but BCVA was improved postoperatively (all P<0.05).However,UCVA in group A was better at 3 months than at 1 month,and 1 month was better than 1 week postoperatively,there were statistically significant differences (all P<0.05).In addition,the BCVA was stable at 1 month postoperatively.The corneal astigmatism was lower in group A than in group B at 1 week,1 month and 3 months postoperatively (all P<0.05).Corneal astigmatism in group A at 3 months postoperatively was (0.26±0.20)D,slightly lower than pre-operation data ［(0.32±0.13)D］,but there was no statistically significant difference (P=0.42).In group B,corneal astigmatism at 3 months postoperatively was (0.62±0.45)D,higher than preoperative data ［(0.23±0.17)D］,and there was statistically significant difference (P<0.05).SIA in group A was (1.28±0.63)D,higher than that of group B ［(0.77 ± 0.39)D］ at 1 week postoperatively and there was statistically significant difference (P=0.01),but no statistically significantly difference in SIA between group A and group B at 1 month and 3 months postoperatively (all P＞0.05).Conclusion　Steep axial incision in cataract surgery can’t correct preoperative corneal astigmatism but can effectively decrease total corneal astigmatism postoperatively and improve UCVA in patients who with preoperative corneal astigmatism less than 0.50 D,which is better than temporal corneal incision.
