【摘要】 目的比较不同术式对术后角膜屈光状态和视功能恢复的影响 ,探讨能够在术后早期迅速恢复视力的白内障术式。方法对四组 (2 98例 )老年性白内障分别采用超声乳化白内障吸除及折叠人工晶状体植入 (超乳Ⅰ组 )、超声乳化非折叠晶状体植入 (超乳Ⅱ组 )、小切口非超乳白内障摘除 (小切口组 )和白内障囊外摘除术 (囊外组 )。结果术后第 3d、第 1周平均裸眼视力 ,超乳Ⅰ组与其它组比较 ,视力明显好于其他各组 (P <0 .0 5 ) ;第 1月和第 3月平均裸眼视力 ,超乳Ⅰ组、超乳Ⅱ组、小切口组比较差异无显著性 ,但仍与囊外组有差别。术后平均角膜散光情况 ,术后 1周和 1月时超乳Ⅰ组较其它三组都小 ,与各组比较差别均有显著性 (P <0 .0 5 )。 3月时超乳Ⅰ组的角膜散光与超乳Ⅱ组、小切口组相近 ,两两比较差别无显著性 (P >0 .0 5 ) ,与囊外组有差别。结论采用超声乳化白内障吸除及折叠人工晶状体植入术对术后视力早期恢复和稳定眼屈光状态是最好的一种方法更多还原

【Abstract】 ObjectiveTo compare the influence of different cataract extraction on astigmatism and recovery of vision function.To explore the possibility in establishment of a method of cataract operation capable of recovering normal visual acuity rapidly at the early stage of postoperation. Methods298 eyes with senile cataract were divided into 4 groups:phacoemulsification with silicone foldable intraocular lens(IOL) implantation group (phacoemulsificationⅠ),phacoemulsification with one-piece IOL implantation group (phacoemulsificationⅡ), small incision cataract extraction with one-piece IOL implantation group (small incision) and extracapsular cataract extraction with one-piece IOL implantation group (ECCE). ResultsThe average uncorrect visual acuity of phacoemulsification Ⅰ group was significantly better than that of other groups 3 d and 1 week after the operation(P< 0.05).No difference was found in the average uncorrect visual acuities among phacoemulsification Ⅰ group, phacoemulsification Ⅱ group and small incision group 1 month and 3 month after operation,while notable difference was seen between these three groups and that of ECCE group(P< 0.05). The mean postoperative astgmatism of phacoemulsification Ⅰ group was significantly less than that of other groups 1 week and 1 month after operation (P< 0.05).The mean postoperative astgmatism of phacoemulsification Ⅰ group was not significantly different from that of phacoemulsification Ⅱ group and small incision group 3 month after the operation(P> 0.05),which was different from that of ECCE group(P< 0.05). ConclusionThe phacoemulsification with foldable intraocular lens implantation was the best method in rehabilitating visual acuity and stabilizing the refractive situation at the early stage of postoperation.更多还原
