【摘要】：目的:對比最大角膜屈光力子午線軸位的透明角膜切口與傳統(tǒng)白內(nèi)障超聲乳化術(shù)后角膜散光的變化。方法:將58例(60只眼)白內(nèi)障患者隨機(jī)分為A、B兩組。A組從最大角膜屈光力子午線軸位做3.0mm透明角膜切口,B組從傳統(tǒng)顳上側(cè)(右眼)或鼻上側(cè)(左眼)行3.0 mm透明角膜切口。兩組均行白內(nèi)障超聲乳化吸除術(shù)聯(lián)合可折疊式人工晶體植入術(shù)。分別于術(shù)前及術(shù)后1 d、術(shù)后1周、術(shù)后1個(gè)月用CT200角膜地形圖儀測量角膜散光度和軸向并計(jì)算手術(shù)源性散光度。比較兩組術(shù)后不同時(shí)間的角膜散光度、手術(shù)源性散光度和裸眼視力。結(jié)果:A、B兩組術(shù)前和術(shù)后各階段視力比較差異無統(tǒng)計(jì)學(xué)意義(均P0.05)。兩組術(shù)后1周和術(shù)后1個(gè)月平均角膜散光度A組B組,差異有統(tǒng)計(jì)學(xué)意義(均P0.05)。術(shù)后1周和術(shù)后1個(gè)月角膜散光的矢量分析A組B組,差異均有統(tǒng)計(jì)學(xué)意義(均P0.05)。結(jié)論:相對于傳統(tǒng)手術(shù)切口,白內(nèi)障手術(shù)中選擇角膜最大曲率方向做透明角膜切口,能夠使患者術(shù)后的角膜散光度和手術(shù)源性散光度減小。
[Abstract]:Objective: To compare the changes of corneal astigmatism corneal refractive power maximum radial axis of the transparent corneal incision and traditional cataract after phacoemulsification. Methods: 58 cases (60 eyes) of cataract patients were randomly divided into A, B two group.A group from the maximum corneal refractive power radial axis 3.0mm transparent corneal incision, group B from the traditional temporal side (right eye) or nasal side (left) for 3 mm clear corneal incision. The two groups underwent phacoemulsification and foldable IOL implantation. Before and after surgery to 1 D, after 1 weeks, 1 months after operation with CT200 angle membrane topography measurement of corneal astigmatism and axial and the calculation of surgically induced astigmatism degree. The two groups were compared after different time of corneal astigmatism, surgically induced astigmatism and uncorrected visual acuity. Results: A, B two groups had no statistical significance before and after surgery in each stage of visual acuity difference (P0.05) for 1 weeks. The two groups after operation And 1 months after surgery, the average corneal astigmatism of group A B group, the difference was statistically significant (P0.05). After 1 week and 1 months vector of corneal astigmatism of group A B group, the differences were statistically significant (P0.05). Conclusion: compared with traditional surgical incision cataract surgery in selected choose the maximum corneal curvature direction of clear corneal incision, can make patients with postoperative corneal astigmatism and surgical astigmatism is reduced.
