药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.患者球镜度数-1.0D-- -10.D,柱镜度数小于等于-1.5D.
2.患者2年内屈光度数较稳定
3.戴硬性角膜接触镜的患者需停戴接触镜4周,软镜需停戴2周
4.戴角膜接触镜的患者,手术当天术眼角膜曲率及验光数据与之前检查数据无太大差异(不超过0.5D),如有,应待屈光状态稳定后再重新安排手术。
5.患者最佳矫正视力达到1.0或以上
6.患者的角膜地形图形态正常
7.患者的暗室瞳孔直径在6-8mm之间
8.患者年龄在21-35岁之间
9.患者需自愿签署知情同意书
10.在研究期间患者需有能力且自愿进行随访。

Inclusion criteria

1. Patients must have-1.00D to-10.00D of manifest spherical equivalent myopiaand less than 1.5D astigmatism;
2. Patients must have had a stable refraction for the last 24 months as documented by previous clinical records, i.e., spherical or cylindrical portion of the manifest refraction has not progressed at a rate of more than +0.5D during the year prior to the baseline examination;
3. Patients who are hard (PMMA) contact lens wearers must discontinue their hard lenses for at least 4 weeks prior to the preoperative evaluation, and patients who are soft lens contact lens wearers must discontinue their lenses for at least 2 weeks prior to the preoperative evaluation. If the investigator determines that the topography is unaffected by contact lens use, surgery may be scheduled one week or less after the initial exam, with no contact lens wear permitted prior to the surgery;
4. For patients who are contact lens wearers, if, on the day of scheduled surgery central simulated keratometry readings and manifest refraction spherical equivalents do not differ significantly from the initial exam measurements (by more than 0.50 diopter), surgery may proceed. If the refractive change exceeds this criterion, the surgery should be rescheduled after refractive stability is achieved;
5. Patients best spectacle corrected visual acuity must be 20/20 or better in each eye;
6. Patients corneal topography must be normal;
7. Patients pupil size in dim condition must be smaller than 8mm and larger than 6mm as well (in order to minimize interference of the differences of pupil size);
8. Patients aged 21 to 35 years old;
9. Patients must sign a written Informed Consent form;
10. Patients must be able and willing to return for scheduled follow-up examinations for the duration of the study.

排除标准:

1.患者有潜在的、反复发作或进行性的角膜疾病、角膜异常(尤其是复发性角膜糜烂、严重的基质病变、圆锥角膜、透明性边缘性角膜变性)或是手术范围内的角膜疤痕
2.患者单眼或双眼角膜形态不规则
3.患者近视度数有进展
4.患者正在服用一些可能会影响伤口愈合的系统性药物,如肾上腺皮质激素和抗代谢药
5.患者免疫功能不全或有结缔组织病、显性遗传疾病或糖尿病
6.患者既往有眼部手术史
7.患者中央角膜曲率不规则
8.患者对于研究中使用的药物过敏
9.患者有青光眼病史或青光眼可疑
10.患者在试验期间参加其他试验
11.患者有疱疹性角膜炎病史
12.女性患者在怀孕期或哺乳期或计划怀孕期
13.患者术后可能会出现斜视
14.患者患系统性疾病尤其是血管性疾病,如:风湿性疾病,系统性红斑狼疮或干燥症
15. 患者患有眼球震颤或在手术期间不能长时间固视
16.患者术后剩余角膜基质厚度少于250um

Exclusion criteria:

1. Patients with residual, recurrent, or active ocular disease, corneal abnormality (specifically, recurrent corneal erosion, severe basement membrane disease, keratoconus, pellucid marginal degeneration), or previous corneal scarring in the treatment zone;
2. Patients who have irregularity in either left, right or both eyes;
3. Patients with ophthalmoscopic signs of progressive or unstable myopia;
4. Patients taking systemic medication likely to affect wound healing, such as corticosteroids or antimetabolites;
5. Patients who are immunocompromised or carrying diagnosis of connective tissue disease, or clinically significant atopic disease or diabetes;
6. Patients who have undergone previous intraocular or corneal surgery of any kind in the operative eye, including any type of excimer laser surgery for either refractive or therapeutic purposes;
7. Patients with unstable central keratometry readings with irregular mires;
8. Patients who have a known sensitivity to study medication;
9. Patients who have a history of glaucoma or who are glaucoma suspect;
10. Patients who are participating in other ophthalmic clinical trials during this clinical investigation;
11. Patients who have a history of herpes simplex or herpes zoster keratitis;
12. Women who are pregnant, lactating, or planning to become pregnant over the course of this clinical investigation;
13. Patients who are at risk for developing strabismus after the treatment;
14. Patients with a systemic disease that would influence corneal wound healing, particularly collagen vascular diseases, including rheumatoid arthritis, systemic lupus, and Sj?grens syndrome;
15. Patients with nystagmus or any other condition which would prevent a steady gaze during surgery or other tests;
16. Patients with residual central corner thickness of less than 250 microns after subtracting the ablation depth.
