目的探讨散光陡峭轴切口在白内障超声乳化多焦点人工晶状体植入术中的应用效果。方法将28例(35眼)白内障患者随机分成两组,A组14例16眼,采用11点钟位透明角膜3.0 mm切口;B组14例19眼,在散光陡峭轴方位行透明角膜3.0 mm切口。所有患者均行超声乳化+人工晶状体植入术,术中植入多焦点人工晶状体。于术后1周、1个月、3个月观察患者角膜散光及裸眼远、近视力情况。结果 A组患者术后1周、1个月、3个月裸眼远视力分别为0.62±0.20、0.71±0.62、0.75±0.20,近视力分别为0.49±0.18、0.51±0.20、0.62±0.20;B组各时间点裸眼远视力分别为0.84±0.52、0.86±0.22、0.91±0.42,近视力分别为0.57±0.26、0.61±0.22、0.69±0.18,B组各时间点均好于A组,差异均有统计学意义(均为P<0.05)。A组患者术后1个月、3个月时散光分别为(1.13±0.64)D和(1.03±0.34)D,B组分别为(0.89±0.40)D、(0.56±0.38)D,B组角膜散光小于A组,差异均有统计学意义(均为P<0.05)。结论于散光陡峭轴行角膜切口可以降低白内障术后的角膜散光,提高多焦点人工晶状体植入术后的远、近视力。
Objective To compare the applied effects of clear corneal steep axis incision in phacoemulsification with multifocal intraocular lens (MIOL) implantation. Methods A total of 28 cataract patients ( 35 eyes) were randomly divided into two groups. All patients performed the phacoemulsification with MIOL implantation. Four- teen patients ( 16 eyes)were in group A with 3.0 mm incision at 11 :00 clock of cornea, 14 patients ( 19 eyes)were in group B with clear incision position at steep axis. The un- corrected distant visual acuity ( UCDVA), uncorrected near visual acuity (UCNVA) and corneal astigmatism were observed at postoperative 1 week, 1 month and 3 months. Re- suits UCDVA in group A at postoperative 1 week, 1 month,3 months were 0.52 ± 0. 20,0.71 ± 0.52 and 0.75 ±0.2{), respectively, which in group B were 0. 84 ± 1.52, 0.86 ±0.22 and 0.91 ±0.42 ,respectively. UCNVA in group A at postoperative l week, 1 month, 3 months were 0.49 ± 0. 18,0.51 ± 0.20 and 0.62 ± 0. 20, respectively, which in group B were 0.57 ±0.25,0.61 ±0.22 and 0.59 ±0.18 ,respectively. The visual acuity in group B was better than that in group A at each time point ( all P 〈 0.05 ). The corneal astigmatism at postoperative 1 month, 3 months in group A were (1.13 ± 0.54 )D and ( 1.03 ± 0. 34) D, respectively, which were higher than that in group B ( 0. 89 ±0. 40 ) D and (0.55 ± 0.38 ) D, there were statistical differences ( all P 〈 0.05 ). Conclusion Making corneal incision at steep axis can reduce postoperative astigmatism and improve UCDVA, UCNVA after phacoemulsification with MIOL implantation.
