研究目的:

研究拟通过对在飞秒激光小切口基质透镜取出术(SMILE)中基质囊袋中冲洗组与未冲洗组进行对比,对术前、术后多个时间点视力、眼压、角膜厚度、角膜密度、形态结构、生物力学、内皮等随访监测,以评估在SMILE手术中,基质囊袋中冲洗是否会增加抑或降低术后感染风险,对术后视力等相关参数是否造成影响及何种影响,对临床SMILE手术过程中操作方式的选择、术后视觉效果的优化及术后感染的风险预测提供思路和参考。  

Objectives of Study:

The purpose of this study is to compare the flushing group with the non-flushing group in femtosecond laser mini-incision matrix lens extraction (SMILE), and to monitor the visual acuity, intraocular pressure, corneal thickness, corneal density, morphological structure, biomechanics and endothelium at different time points before and after SMILE, in order to evaluate whether flushing in the matrix bag will increase or decrease after SMILE. The risk of infection, whether or not it affects the visual acuity and other related parameters after SMILE operation, provides ideas and references for the selection of operation mode, the optimization of visual effect after SMILE operation and the prediction of the risk of infection after SMILE operation.

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)患者本人具有通过SMILE改善屈光状态的愿望,心理健康,对手术疗效具有合理的期望。2)年龄在18周岁及以上的近视 、散光患者(特殊情况除外,如具有择业要求、高度屈光参差等);术前在充分理解的基础上,患者本人或必要时家属须共同签署知情同意书。3)屈光度数:相对稳定(在过去1年内屈光 度数变化≤0.50 D)。范围为球镜度数- 1.00~-10.00 D,柱镜度数≤-5.00 D。4)角膜:透明无明显云翳或斑翳;角膜地形图检查形态正常,无圆锥角膜倾向。5)无其他眼部疾病和(或)影响手术恢复的全身器质性病变。6)经术前检查排除手术禁忌证者。

Inclusion criteria

1) The patients themselves have the desire to improve refractive status through SMILE, and have reasonable expectations for the effect of surgery. 2) Myopia and astigmatism patients aged 18 years and over (except for special cases, such as job-hunting requirements, high anisometropia, etc.). Before operation, on the basis of full understanding, the patients themselves or their family members should sign the informed consent together if necessary. 3) Diopter: relatively stable (the change of diopter in the past year is less than 0.50 D). The range is spherical - 1.00 - 10.00 D and cylindrical - 5.00 D. 4) Cornea: transparent without obvious clouds or patches; corneal topographic examination showed normal morphology and no keratoconus tendency. 5) There were no other eye diseases and/or systemic organic lesions affecting the recovery of surgery. 6) The contraindication of operation was excluded by preoperative examination.

排除标准:

1)患者头位不能处于正常位置。2)重度弱视。3)圆锥角膜或可疑圆锥角膜。4)其他角膜扩张性疾病及变性。5)近期反复发作病毒性角膜炎等角膜疾病。6)重度干眼、干燥综合征。7)角膜过薄,预计透镜取出后角膜中央残留基质床厚度<250 μm(一般角膜基质床剩余厚度应至少>250um,建议280um以上)。8)存在活动性眼部病变或感染。9)严重的眼附属器病变,如眼睑缺损和变形、严重眼睑闭合不全。10)未控制的青光眼、严重影响视力的白内障、严重的角膜疾病,如明显的角膜斑翳等角膜混浊、边缘性角膜变性、角膜基质或内皮营养不良以及其他角膜疾病,角膜移植术后、放射状角膜切开术后等角膜手术后,眼外伤、严重眼表和眼底疾病等。11)存在全身结缔组织疾病或自身免疫性疾病,如系统性红斑狼疮、类风湿关节炎,多发性硬化等。12)已知存在焦虑、抑郁等严重心理、精神疾病。13)全身系统性疾病或精神疾病,如癫痫、癔症等致无法配合检查和手术的疾病。

Exclusion criteria:

1) The patient's head position can not be in normal position. 2) Severe amblyopia. 3) keratoconus or suspected keratoconus. 4) Other corneal dilatation and degeneration. 5) Recent recurrent corneal diseases such as viral keratitis. 6) Severe dry eye and Sjogren's syndrome. 7) The cornea is too thin. It is estimated that the thickness of residual stromal bed in the central cornea after lens removal is less than 250 um. (In general, the residual thickness of corneal stromal bed should be at least > 250 um, and it is recommended that the thickness of residual stromal bed be more than 280 um.) 8) There are active ocular lesions or infections. 9) Severe ocular adnexal lesions, such as eyelid defect and deformation, and severe eyelid insufficiency. 10) Uncontrolled glaucoma, cataract seriously affecting vision, serious corneal diseases, such as obvious corneal opacity, marginal corneal degeneration, corneal stromal or endothelial dystrophy and other corneal diseases, corneal trauma, serious ocular surface and fundus diseases after corneal transplantation, radial keratotomy and other corneal operations. 11) There are systemic connective tissue diseases or autoimmune diseases, such as systemic lupus erythematosus, rheumatoid arthritis, multiple sclerosis and so on. 12) Severe mental and psychiatric disorders such as anxiety and depression are known to exist. 13) Systemic or psychiatric disorders, such as epilepsy and hysteria, resulting in diseases that are unable to cooperate with examinations and operations.
