At Blue Fin Vision® Eye Clinic, we understand that the decision to undergo laser eye surgery is a significant one. With advancements in technology, laser eye surgery has become a safe, effective, and life-changing solution for those seeking freedom from glasses or contact lenses. Whether you’re considering LASIK, LASEK, PRK (transPRK), or Lenticule Extraction, our expert team in London is here to guide you every step of the way.
What Is Laser Eye Surgery?
Laser eye surgery is a highly precise procedure that reshapes the cornea – the transparent front layer of the eye – to correct refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness), and astigmatism. By altering the way light enters the eye and focuses on the retina, laser eye surgery can significantly improve vision.
At Blue Fin Vision®, we offer a range of cutting-edge procedures tailored to your unique needs. Let’s explore how each type works.
Types of Laser Eye Surgery
- LASIK – The Most Popular Option
LASIK (Laser-Assisted In Situ Keratomileusis) is one of the most commonly performed laser eye surgeries due to its quick recovery time and minimal discomfort.
How It Works:
- A femtosecond laser creates a thin flap on the surface of the cornea.
- The flap is gently lifted to expose the underlying corneal tissue.
- An excimer laser reshapes the cornea by removing microscopic amounts of tissue, correcting your prescription.
- The flap is then repositioned, acting as a natural bandage.
Benefits:
- Rapid recovery – most patients experience improved vision within hours.
- Minimal discomfort during and after the procedure.
- Suitable for a wide range of prescriptions.
- LASEK – A Surface Procedure
LASEK (Laser-Assisted Sub-Epithelial Keratomileusis) is ideal for patients with thinner corneas or those unsuitable for LASIK.
How It Works:
- The outer layer of the cornea (epithelium) is loosened using an alcohol solution and gently moved aside.
- The excimer laser reshapes the underlying corneal tissue.
- The epithelium is repositioned, and a protective contact lens is applied to aid healing.
Benefits:
- A safer option for patients with thin or irregular corneas.
- Provides excellent visual outcomes like LASIK.
- PRK (transPRK) – The Original Technique
PRK (Photorefractive Keratectomy) or transPRK is one of the earliest forms of laser eye surgery. It’s often recommended for patients with specific corneal conditions.
How It Works:
- The outer layer of the cornea is completely removed to access the stromal tissue underneath.
- The excimer laser reshapes the cornea to correct vision.
- A protective contact lens is placed over the eye as the epithelium regenerates.
Benefits:
- No flap creation, making it suitable for patients with thin corneas.
- Highly precise and effective for certain prescriptions.
- Lenticule Extraction – Minimally Invasive Vision Correction
Procedures such as SMILE/SmartSight/SILK/CLEAR represent the latest generation of laser eye surgery. They are less invasive than LASIK and ideal for those seeking a keyhole procedure.
How It Works:
- A femtosecond laser creates a small lenticule (a disc-shaped piece of tissue) within the cornea through a tiny incision.
- The lenticule is removed through this incision, reshaping the cornea and correcting your vision.
Benefits:
- No flap creation, reducing the risk of complications.
- Minimal discomfort during recovery.
- Rapid visual improvement like LASIK.
What Happens During Laser Eye Surgery?
Regardless of which procedure you choose, all laser eye surgeries follow these general steps:
- Preparation: Numbing drops are applied to ensure comfort. A lid speculum gently holds your eyelids open.
- Laser Treatment: Depending on the procedure, your surgeon will use either an excimer or femtosecond laser to reshape your cornea with unparalleled precision.
- Post-Treatment Care: Protective measures such as contact lenses or shields may be applied to promote healing.
The entire process typically takes less than 30 minutes per eye, and most patients remain awake throughout.
