摘要
目的:探讨不同基弧软性角膜接触镜对准分子激光上皮下角膜磨镶术(LASEK)的影响。方法:对186例372眼近视患者施行LASEK手术,随机分为观察组和对照组,激光切削后分别配戴-1.0D基弧为8.7,8.5mm的软性角膜接触镜。术后1,3,5d比较两组术后角膜刺激症状,术后5d比较角膜上皮愈合时间、裸眼视力,术后1mo比较两组裸眼视力,术后3mo比较角膜上皮下雾状混浊(haze)程度。结果:术后1,3,5d观察组角膜刺激症状明显好于对照组,差异有统计学意义(P<0.05)。术后5d角膜上皮愈合时间、裸眼视力观察组明显好于对照组,差异有统计学意义(P<0.05)。术后1mo两组裸眼视力无明显差别,差异无统计学意义(P>0.05)。术后3mo两组haze比较差异无统计学意义(P>0.05)。结论:LASEK术后应适当增加需配戴的软性角膜接触镜的基弧,可以减轻角膜刺激症状,促进角膜上皮愈合和视力恢复。
AIM: To explore the effect of soft corneal contact lens with different base curve on laser epithelial keratomileusis ( LASEK) . METHEDS: Totally 186 cases ( 372 eyes ) with myopia underwent LASEK surgery were divided into the observation group and the control group randomly, respectively wearing soft corneal lens -1.0D with 8.7mm and 8.5mm base curve.The comparison and observation were conducted in terms of corneal irritation at postoperative 1, 3 and 5d, the time of healing the epithelium and visual recovery in these two groups at 5d, the uncorrected visual acuity refraction at 1mo, and the degree of haze at 3 mo. RESULTS: Corneal irritation in the observation group was much better than that in the control group at postoperative 1, 3 and 5d, there was significant difference (P&lt;0.05).There was significant difference in the healing of epithelium and uncorrected visual acuity at postoperative 5d, the difference was significant (P&lt;0.05). There was no significant difference of the uncorrected visual acuity at postoperative 1mo (P&gt;0.05), and there was no significant difference of haze at postoperative 3mo between two groups (P&gt;0.05). CONCLUSION: Wearing bigger base curve soft corneal contact lens is a safe and efficient method for LASEK than smaller with the advantages of having mild irritating symptom, a shorter time of healing the epithelium and the visual acuity.
