摘要:

背景:白内障摘除联合人工晶状体植入部分患者晶状体植入后依然存在不同程度屈光不正现象,可以采用准分子激光上皮下角膜磨镶或准分子激光原位角膜磨镶矫正屈光不正。

 

目的:观察应用准分子激光上皮下角膜磨镶矫治白内障摘除联合人工晶状体植入后残留屈光不正的效果。

 

方法:纳入白内障摘除联合人工晶状体植入后残留屈光不正38例(45眼),其中男22例,女16例;年龄24-74岁;角膜中央厚度490-590 μm,准分子激光上皮下角膜磨镶前裸眼视力为0.1-0.3,矫正视力为0.6-1.0。均应用准分子激光上皮下角膜磨镶进行矫治,术后随访12个月,观察裸眼视力、最佳矫正视力、屈光度、眼压等情况。

 

结果与结论:大部分患者于术后3-6 h后有异物感、疼痛等眼部刺激症状,术后2 d内有不同程度的眼痛、畏光、流泪等角膜刺激症状,术后7 d左右角膜上皮基本愈合,20 d左右视力基本恢复到最佳。术后12个月时裸眼视力均≥0.6,其中26眼视力达到或超过1.0(58%),35眼(78%)术后裸眼视力达到或超过术前最佳矫正视力。术后12个月裸眼视力为0.6-1.2。球镜度数从术前平均-2.5 m-1降至术后-0.5 m-1,柱镜度数从术前平均-3.85 m-1降至术后-0.53 m-1。12眼发生眼压偏高,5眼有0.5级角膜上皮下雾状混浊形成。结果说明准分子激光上皮下角膜磨镶治疗白内障摘除联合人工晶状体植入后屈光不正是安全有效的。

Abstract:

BACKGROUND: After cataract extraction and intraocular lens implantation, some patients still appear to suffer from refractive errors to varying degrees. In this case, excimer laser epithelial keratomileusis or excimer laser in situ keratomileusis can be used for correction of refractive errors.

OBJECTIVE: To observe the therapeutic effect of excimer laser epithelial keratomileusis on the treatment of residual refractive errors after cataract extraction and intraocular lens implantation.
METHODS: Thirty-eight patients with refractive errors (45 eyes) who had received cataract extraction and intraocular lens implantation were enrolled, including 22 males and 16 females. Patient’s age was 24-74 years, and the central corneal thickness ranged 490-590 μm. Before laser epithelial keratomileusis, the uncorrected visual acuity and corrected visual acuity were 0.1-0.3 and 0.6-1.0, respectively. The uncorrected visual acuity, best corrected visual acuity, diopter, and intraocular pressure were observed at 12 months after correction.
RESULTS AND CONCLUSION: Most of the patients had foreign body sensation, pain and other symptoms of eye irritation at 3-6 postoperative hours, and then presented with eye pain, photophobia, tearing and other symptoms of corneal irritation with 2 days after surgery. The corneal epithelium healed basically at 7 days after surgery, and the vision recovered to top after about 20 days. After 12 months, the uncorrected visual acuity was 0.6-1.2, ≥ 0.6 in all eyes, 1.0 in 26 eyes (58%) and reached or exceeded the preoperative best corrected visual acuity in 35 eyes (78%). After surgery, the spherical degree was decreased from -2.5 m-1 to 0.5 m-1, and the cylinder degree was reduced from -3.85 m-1 to -0.53 m-1. High intraocular pressure occurred in 12 eyes, and 0.5-level corneal haze formed in 5 eyes. The results demonstrate that the excimer laser epithelial keratomileusis is safe and effective for treatment of refractive errors after cataract extraction and intraocular lens implantation.
