目的观察双手微切口白内障超声乳化术对角膜散光的影响。方法将年龄相关性白内障分为两组,A组50例53眼行双手微切口白内障超声乳化术,B组53例60眼行常规白内障超声乳化,观察两组术后角膜散光和视力恢复。结果术后1天两组角膜散光有显著统计学差异(p<0.01),术后1周两组角膜散光的差异仍有统计学意义(p<0.05),术后1个月、3个月角膜散光的差异无统计学意义(p>0.05)。两组视力比较,术后1天及1周差异有统计学意义(p<0.05),术后1个月及3个月无统计学差异(p>0.05)。结论双手微切口白内障超声乳化术较常规白内障超声乳化术,具有更小的手术源性散光和更快的视功能恢复。
Objective To observe the effect of micromanipulation cataract phacoemulsification on corneal astigmatism. Methods Age-related cataracts were divided into two groups. A group of 50 patients (53 eyes) underwent bilateral micro-incision cataract phacoemulsification. Group B (53 patients) 60 eyes underwent conventional phacoemulsification. Corneal astigmatism and visual acuity were observed after operation. Results There was a significant difference in corneal astigmatism (P <0.01) between the two groups at 1 day after surgery. There was still a significant difference in corneal astigmatism between the two groups at 1 week after surgery (p <0.05), at 1 month and 3 months Corneal astigmatism was not statistically different (p> 0.05). There was no significant difference in visual acuity between the two groups at 1 day and 1 week after operation (p <0.05). There was no significant difference at 1 month and 3 months after operation (p> 0.05). Conclusions Two-handed micro-incision phacoemulsification is more effective than conventional cataract phacoemulsification with less surgical astigmatism and faster visual function recovery.
