Femto-LASIK 是矫正近视、远视和散光最安全的手术之一。它是 LASIK（激光原位角膜磨镶术）的一种，无需使用刀片在角膜表面开孔，因此 Femto-LASIK 有时也被称为无刀片 LASIK。
飞秒激光代替了刀片，在角膜上形成一个小切口，暴露眼球，为准分子激光矫正眼球屈光状况做好准备。飞秒激光通过使用极短的能量脉冲来制作角膜瓣，而不会对周围组织造成任何损伤。这种干净利落的切口也意味着手术愈合过程中并发症风险的降低。
Femto-LASIK 最适合 18 岁及以上、认为助视器（眼镜、变焦镜或隐形眼镜）不实用的成年人。患者还必须有稳定的视力，即至少 12 个月内眼镜或隐形眼镜度数没有变化。
Ideal patients must also not be taking any medications that may change their vision, or have any hormonal fluctuations that can affect visual acuity, including breastfeeding or diabetes. You may not be suitable for Femto-LASIK if you have previously undergone refractory surgeries or procedures. The thickness of your cornea will be examined during your initial consultation to determine your suitability for the procedure.
如果您想了解更多信息，请与我们的伦敦外科医生会面。
您将与 EuroEyes 伦敦眼科中心的专家眼科医生进行个人咨询，他们将通过眼球波前分析来创建角膜表面的个人图像。这样，我们就能确定您是否适合做 Femto-LASIK 手术，并讨论您的个性化 Femto-LASIK 治疗方案。
治疗前将对您的眼睛进行全面的初步检查和测量。专家会向您详细讲解手术过程，并提供术后护理说明。
就诊前至少一周内不能佩戴软性隐形眼镜，至少两周内不能佩戴硬性隐形眼镜。
您将接受眼药水麻醉。
使用飞秒激光以对组织温和的方式制备角膜瓣。激光对每只眼睛进行单独治疗，精确度和均匀性都很高。
根据波前分析，准分子激光器会矫正您的屈光不正，并制作角膜模型。
然后再将皮瓣折回。由于内部的粘合力，皮瓣具有自粘性，因此无需缝合。
治疗当天，我们建议您穿着舒适，不要自己开车前往就诊地点。我们建议您找人代驾、乘坐出租车或公共交通工具。您可以正常饮食，但必须避免吸烟。
最好不要化妆和喷香水，以干净的面容赴约。您无需佩戴任何眼罩或绷带，双眼的手术过程一般持续 25 分钟左右。
您应避免揉眼睛，并按照外科医生的指示继续使用抗生素眼药水。根据眼睛的舒适度，您可以根据需要使用润滑眼药水或 "人工泪液"。
我们建议在手术后三天内避免任何专业或体育活动。此外，您还应在两周后再使用任何泳池或桑拿。在医生确认您已经准备好之前，请避免驾驶汽车或操作重型机械。
对患者来说，Femto-LASIK 是矫正远近视或散光的最佳治疗方法之一。
优势包括
Femto-LASIK 是一种门诊手术，持续时间不超过 30 分钟。术后数周即可恢复，无需佩戴眼罩或缠绷带。手术后，您可能会立即感觉眼睛里有东西，但这种感觉会在接下来的几个小时内消失，眼药水会减轻这种感觉。
Immediately following the surgery, your vision may be blurry, but this is only temporary and will clear up over the following week while you use your antibiotic eyedrops.
Femto-LASIK 手术常见的副作用包括
Like any surgical procedure, Femto-LASIK carries a small level of risk. However, modern laser eye surgery is considered extremely safe, particularly when performed by experienced refractive surgeons using advanced diagnostic technology. Most side effects are temporary and can be managed effectively by carefully following the aftercare instructions provided by your surgeon.
The surgeons at EuroEyes London are highly experienced in the field of refractive surgery and use some of the most advanced laser eye surgery technology available today. Every procedure is carried out by qualified ophthalmologists who have collectively performed thousands of successful treatments over more than three decades.
While complications are uncommon, there is still a small possibility of temporary effects such as dry eyes, inflammation or light sensitivity during the healing process. For this reason, patients are advised to carefully follow the guidance provided by our clinical team and attend all recommended follow-up appointments. You can also learn more about what to expect when visiting our clinic by exploring our London eye clinic. At EuroEyes London, our team remains available throughout your recovery to provide support and advice as your vision stabilises. If you would like to find out whether Femto-LASIK is suitable for you, we invite you to book a consultation with one of our experienced surgeons.
One of the most common concerns patients raise during a consultation at our London clinic is how their current prescription affects everyday vision. Many people rely on glasses or contact lenses to see clearly when driving, watching television, using a computer or carrying out day-to-day tasks. LASIK eye surgery is designed to correct these common refractive errors by reshaping the cornea so that light focuses more accurately on the retina.
Using highly precise laser technology, LASIK treatment can correct vision problems such as short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism. For many patients, the procedure can significantly reduce or remove the need for glasses or contact lenses, helping restore clear and comfortable vision across the distances used in everyday life. The table below illustrates how LASIK eye surgery can improve visual clarity for common daily activities.
| Vision Distance | Without Vision Correction | After LASIK Eye Surgery |
|---|---|---|
|
Near Vision 30–50 cm Reading messages, books, menus |
Often blurred without glasses or contact lenses |
Clearer near vision depending on prescription |
|
Intermediate Vision 60–100 cm Computer screens, cooking, dashboards |
Often requires glasses or contacts |
Improved visual clarity for daily tasks |
|
Distance Vision 2 metres + Driving, watching TV, outdoor vision |
Often blurred without glasses or contact lenses |
Clear distance vision without glasses for many patients |
| Everyday Vision Experience | Dependence on glasses or contact lenses for clear vision | Many patients experience clearer vision across everyday activities without relying on glasses |
"LASIK is an advanced form of laser eye surgery designed to correct common refractive errors such as short-sightedness (myopia), long-sightedness (hyperopia) and astigmatism. Using highly precise laser technology, the procedure gently reshapes the cornea so that light can focus more accurately on the retina. This allows many patients to achieve clearer distance vision and significantly reduce their dependence on glasses or contact lenses for everyday activities such as driving, watching television and using digital screens."
所有接受 Femto-LASIK 激光眼科治疗的患者必须年满 18 周岁。不过，在我们的伦敦诊所，我们也为 20-39 岁年龄组的患者提供其他激光治疗方法。
在进行任何激光眼科治疗前，您的视力或度数至少应稳定一年。
激光治疗后，您的视力需要几个小时才能开始恢复。通常情况下，Femto-LASIK 术后 24 小时，视力会恢复到 80%-90% 的水平。治疗后三天内，您将拥有完全的视力。
虽然并发症极少，但激光眼科手术始终存在风险。在伦敦欧洲眼科中心，我们非常注重保持高标准的质量和卫生，以尽可能降低并发症的发生率。
真正的并发症极为罕见。为了避免出现任何愈合问题，所有患者都必须明确、仔细地遵循术后护理建议。我们强烈建议所有患者都坚持复诊，这样我们的专家就能随时了解眼睛的愈合情况，并提前发现任何问题。
激光视力矫正过程中可能出现的任何副作用通常都是短期的、无害的，并且可以通过治疗完全恢复。
根据恢复情况，建议在三四周后进行眼部化妆、游泳或桑拿。外科医生会在复诊时了解您的恢复情况，然后告诉您何时可以安全地再次进行这些活动。
