研究目的:

本研究通过比较不同角膜切口位置对EVO ICL术后泪液功能及视觉质量的影响,旨在为术后管理和干眼症的预测提供依据。研究拟通过分析术后角膜内皮及眼压变化,评估手术的可行性及安全性,进一步推广该术式。  

Objectives of Study:

This study compared the effects of different corneal incision positions on tear function and visual quality after EVO ICL surgery, aiming to provide a basis for postoperative management and the prediction of dry eye syndrome. The study intends to assess the feasibility and safety of the surgery by analyzing the changes in corneal endothelium and intraocular pressure after the surgery, and further promote this surgical method.

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄:18-45岁;2.佩戴角膜接触镜的患者,建议术前停戴角膜接触镜,一般建议软镜停戴1周,硬性透氧性角膜接触镜停戴3周,角膜塑形镜停戴3个月;3.无眼部疾病、外伤及手术史;4.无家族史,尤其角膜营养不良及青光眼等眼病史;5.无全身疾病史;6.无药物史、药物不良反应及过敏史;7.患者本人有通过晶状体眼后房型人工晶状体植入术改善屈光状态的愿望,对手术疗效具有合理的期望;8.近视眼或合并散光的患者,一般要求屈光度数相对稳定,即连续2年每年屈光度数变化<=0.50 D;9.角膜内皮细胞计数 >=2000个/mm2,细胞形态稳定;10.前房深度 >=2.80 mm且房角开放;11.无其他明显影响视力的眼部疾病和(或)影响手术恢复的全身器质性病变。

Inclusion criteria

1. Age: 18 - 45 years old; 2. For patients wearing contact lenses, it is recommended to stop wearing them before the surgery. Generally, soft lenses should be discontinued for 1 week, rigid gas-permeable contact lenses for 3 weeks, and orthokeratology lenses for 3 months; 3. No eye diseases, trauma or surgical history; 4. No family history, especially no history of corneal dystrophy or glaucoma; 5. No history of systemic diseases; 6. No history of medication, adverse drug reactions or allergies; 7. The patient has the desire to improve refractive status through posterior chamber intraocular lens implantation of the crystalline lens and has reasonable expectations for the surgical outcome; 8. For patients with myopia or combined astigmatism, it is generally required that the refractive power remain relatively stable, that is, the annual change in refractive power should be <= 0.50 D for two consecutive years; 9. Corneal endothelial cell count >= 2000 cells/mm2, with stable cell morphology; 10. Anterior chamber depth >= 2.80 mm and the angle is open; 11. There are no other obvious eye diseases and/or systemic organic lesions that affect vision and/or the recovery after surgery.

排除标准:

存在下列情况中任何一项者:1.圆锥角膜或其他角膜扩张性变化处于未稳定状态;2.角膜内皮营养不良;3.活动性眼部病变或感染;4.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;5.既往有青光眼、白内障、葡萄膜炎等明显影响视力的眼部疾病;6.严重焦虑、抑郁等心理、精神疾病;7.无法配合检查和手术的疾病,如癫痫、癔症等;8.严重甲状腺功能亢进及其突眼且病情尚未稳定。

Exclusion criteria:

The presence of any one of the following conditions: 1. Unstable keratoconus or other keratectatic changes; 2. Corneal endothelial dystrophy; 3. Active eye disease or infection; 4. Severe ocular adnexal diseases, such as eyelid defect, deformity and severe eyelid dysraphism; 5. Previous glaucoma, cataract, uveitis and other eye diseases that significantly affect vision; 6. Severe anxiety, depression and other psychological and mental diseases; 7. Diseases that cannot cooperate with examination and surgery, such as epilepsy, hysteria, etc. 8. Severe hyperthyroidism with exophthalmos and the condition is not stable.
