摘要
目的探讨不同切口下白内障超声乳化吸除术治疗硬核白内障的效果及对患者视力水平的影响。方法将76例(86眼)硬核白内障患者按照手术切口大小分为研究组(39例,44眼)与对照组(37例,42眼)。研究组行1.8 mm微切口同轴超声乳化吸除术,对照组行3.0 mm标准切口白内障超声乳化吸除术。比较两组患者手术中有效超声乳化时间、超声乳化能量,比较术前、术后1 d、术后7 d、术后30 d患者眼压、患眼裸眼视力、角膜散光度、泪膜功能,比较两组术后并发症发生率。结果两组有效超声乳化时间与超声乳化能量比较差异无统计学意义(P>0.05)。术后1 d、7 d研究组及术后1 d对照组眼压显著低于术前(P<0.05或0.01),术后各时间点两组眼压比较差异无统计学意义(P>0.05);术后各时间点两组裸眼视力均较术前显著提升(P<0.01),研究组较对照组提升更显著(P<0.01);术后30 d研究组角膜散光度显著低于术前(P<0.01),术后1 d、7 d对照组角膜散光度显著高于术前(P<0.05或0.01),研究组术后各时点角膜散光度均显著低于对照组(P<0.05或0.01)。术后各时点两组泪膜破裂时间均显著短于术前(P<0.01),研究组显著长于对照组(P<0.05或0.01);术后1 d、7 d研究组及术后各时点对照组基础泪液分泌量均显著少于术前(P<0.05或0.01),研究组显著多于对照组(P<0.05或0.01)。两组并发症发生率比较差异无统计学意义(P>0.05)。结论1.8 mm同轴微创超声乳化吸除术治疗硬核白内障安全有效,术后患者眼压较为稳定,视力水平恢复较好,角膜散光度降低,泪膜功能恢复良好。
Objective To explore the effect of phacoemulsification of cataract under different incisions in the treatment of hard nucleus cataract and its influence on patients'vision.Methods A toal of 76 patients(86 eyes)with hard nucleus cataract were divided into study group(39 cases,44 eyes)and control group(37 cases,42 eyes)according to the surgical incision size.The study group underwent coaxial phacoemulsification with 1.8 mm microincision,and control group underwent coaxial phacoemulsification with 3.0 mm standard incision.The effective phacoemulsification time and phacoemulsification energy during surgery were compared between the two groups,and the intraocular pressure,uncorrected visual acuity of affected eyes,corneal astigmatism and tear film function were compared before surgery and at 1 d,7 d and 30 d after surgery,and the incidence rates of postoperative complications were compared between the two groups.Results There were no significant differences in the effective phacoemulsification time and phacoemulsification energy between the two groups(P>0.05).The intraocular pressure in study group at 1 d and 7 d after surgery and in control group at 1 d after surgery was significantly lower than that before surgery(P<0.05 or 0.01),and there was no significant difference in intraocular pressure at each time point after surgery between the two groups(P>0.05).The uncorrected visual acuity in the two groups was significantly improved compared with that before surgery(P<0.01),and the improvement was more significant in study group than in control group(P<0.01).The corneal astigmatism in study group at 30 d after surgery and in control group at 1 d and 7 d after surgery was significantly higher than that before surgery(P<0.05 or 0.01),and the corneal astigmatism in study group was significantly lower than that in control group at each time point after surgery(P<0.05 or 0.01).The breakup time of tear film in the two groups was significantly shorter than that before surgery(P<0.01),and the breakup time in study group was significantly longer than that in control group(P<0.05 or 0.01).The amount of basal tear secretion in study group at 1 d and 7 d after surgery and in control group at each time point after surgery was significantly lower than that before surgery(P<0.05 or 0.01),and the amount of basal tear secretion in study group was significantly higher than that in control group(P<0.05 or 0.01).There were no statistically significant difference in the incidence rates of complications between the two groups(P>0.05).Conclusions Coaxial phacoemulsification with 1.8 mm microincision is safe and effective in the treatment of hard nucleus cataract,and has stable intraocular pressure,good visual acuity recovery,reduced corneal astigmatism and good tear film function recovery.
