无晶状体眼二期人工晶状体植入20例临床观察

Clinical observation of phase Ⅱ IOL implantation for 20 patients with aphakia

目的:观察无晶状体眼二期人工晶状体植入的疗效。方法:对20例无晶状体眼的患者,采用睫状沟悬吊固定手术二期植入人工晶状体。随诊3～12mo,观察术后视力、眼压、人工晶状体位置及术中术后并发症。结果:所选20例患者术后第1d裸眼视力0.1～0.3者1例,0.4～0.5者6例,0.6～0.8者12例。眼压平均18～20mmHg。术后角膜水肿1例,经氯化钠眼药水及复方妥布霉素眼药水治疗1wk后吸收。角膜切口处水肿5例,1wk后自行吸收。结膜下出血5例,5～10d吸收。随访3～12mo,20眼手术后人工晶状体位置居中,未发现明显偏斜。无青光眼、视网膜脱离等严重的并发症。老年性白内障术后无晶状体眼的患者二期人工晶状体植入后视力恢复较理想。结论:对于白内障术后无晶状体眼患者,采用睫状沟悬吊固定手术二期植入人工晶状体,不仅获得良好的裸眼视力和矫正视力,同时可减少一系列并发症。

AIM： To observe the effect of phase II intraocular lens （IOL） implantation for aphakia. METHODS：Totally 20 patients with aphakia underwent the suspended fixation of ciliary sulcus and phase II IOL implantation. After follow- up of 3-12 months, visual acuity, intraocular pressure （lOP）, IOL position, and intraoperative and postoperative complications were observed. RESULTS： After the operation, patients visual acuity was 0.1-0.3 in 1 case ,0.4-0.5 in 6 cases ,0.6-0 .8 in 12 cases. The average lOP was 18-20mmHg. After treatment of tobramycin and sodium chloride eye dropping （one week）, corneal edema （1 case） and corneal incision edema （ 5 cases ） were absorped. Subconjunctival hemorrhage were in 5 cases, which was absorpted in 5-10 days. After follow-up of 3-12 months, no obvious lens deflected and serious complications （glaucoma, retinal detachment） appeared. IOL implantation in patients with aphakia after senile cataract surgery have the better visual acuity. CONCLUSION ： Suspended fixation of ciliary sulcus and phase Ⅱ IOL implantation for patients with aphakia have a good visual acuity and corrected visual acuity and less complications.
