London, a global hub of medical excellence, offers cutting-edge refractive surgery options for those seeking freedom from glasses and contact lenses. From the initial consultation to the final check-up, the journey of vision correction is a carefully managed process. Understanding what happens before, during, and after refractive surgery in London can help potential patients feel informed and confident about this life-changing procedure.

Before: The Meticulous Preparation

The journey towards clearer vision begins long before you set foot in the operating room. In London, leading clinics emphasize a thorough pre-operative assessment to determine your suitability for refractive surgery Refractive lens exchange surgery London. This crucial phase typically involves:

• Comprehensive Eye Examination: This isn’t your routine eye test. Specialists will conduct a series of advanced diagnostic tests, including corneal topography (mapping the curvature of your cornea), wavefront analysis (measuring how light travels through your eye), and pachymetry (measuring corneal thickness). These measurements are vital for creating a personalized treatment plan and ensuring the chosen procedure is safe and effective for your unique eye structure.
• Detailed Medical History: You’ll be asked about your general health, any pre-existing medical conditions (like diabetes or autoimmune disorders), and all medications you are currently taking. Certain conditions or medications can affect healing or suitability for surgery.
• Discussion of Expectations and Risks: A reputable London clinic will have an open and honest conversation about what refractive surgery can achieve and any potential risks or side effects. This includes explaining possible outcomes like dry eyes, glare, halos, or the rare need for enhancement procedures. You’ll have ample opportunity to ask questions and address any concerns.
• Contact Lens Holiday: If you wear contact lenses, you’ll be instructed to stop wearing them for a specific period (usually 1-2 weeks for soft lenses, longer for hard lenses) before your consultation and surgery. This is because contact lenses can temporarily alter the shape of your cornea, which could affect the accuracy of pre-operative measurements.
• Pre-Surgery Instructions: You’ll receive clear guidelines on what to do in the days leading up to your surgery. This may include avoiding eye makeup, perfumes, or certain fabrics that can generate lint, and arranging for someone to drive you home after the procedure. Some clinics may also prescribe antibiotic or anti-inflammatory eye drops to start using before surgery.

During: The Swift and Precise Procedure

Refractive surgery in London is typically an outpatient procedure, meaning you go home the same day. While the idea of eye surgery can be daunting, the actual procedure is remarkably quick and generally painless, thanks to advanced technology and local anaesthetics.

• Arrival and Preparation: On the day of your surgery, you’ll arrive at the clinic, where staff will perform a final check of your eyes and administer numbing eye drops. You’ll be made comfortable and guided through the process.
• The Procedure Itself: The exact steps vary depending on the type of refractive surgery (e.g., LASIK, LASEK, SMILE, or Refractive Lens Exchange).
  • LASIK (Laser-Assisted In Situ Keratomileusis): This is the most common type. A femtosecond laser creates a thin, hinged flap in the cornea. This flap is gently lifted, and an excimer laser reshapes the underlying corneal tissue to correct your vision. The flap is then carefully repositioned, and it naturally adheres without stitches. The laser part of the procedure often takes less than a minute per eye.
  • LASEK (Laser-Assisted Sub-Epithelial Keratomileusis) / PRK (Photorefractive Keratectomy): These surface treatments involve removing the outer layer of the cornea (epithelium) before the excimer laser reshapes the underlying tissue. The epithelium then regenerates naturally. These are often recommended for those with thinner corneas or specific lifestyle factors.
  • SMILE (Small Incision Lenticule Extraction): A newer, flapless procedure where a femtosecond laser creates a small, lens-shaped piece of tissue (lenticule) inside the cornea, which is then removed through a tiny incision.
  • Refractive Lens Exchange (RLE): Similar to cataract surgery, this involves removing your natural lens and replacing it with an artificial intraocular lens (IOL) to correct vision. This is often an option for older patients or those with high prescriptions not suitable for laser eye surgery.
• Minimal Discomfort: You will feel pressure or a “tugging” sensation during the procedure, but no pain due to the numbing eye drops. Eye-tracking technology ensures precision even if your eye moves slightly. The entire surgical process for both eyes typically takes between 15-30 minutes, with the laser actively working for only a few seconds.

After: The Road to Optimal Vision

The immediate aftermath of refractive surgery involves a period of rest and careful adherence to post-operative instructions, followed by a gradual return to normal activities and follow-up care.

• Immediate Post-Surgery: Your vision will likely be blurry or foggy immediately after the procedure. You may experience some mild discomfort, a gritty sensation, or watering eyes. You’ll be given protective sunglasses to wear and advised to rest with your eyes closed as much as possible for the first few hours. You will not be able to drive yourself home.
• First Few Days/Weeks:
  • Vision Improvement: For LASIK patients, significant visual improvement is often noticed within 24-48 hours. For LASEK/PRK, recovery takes a bit longer, typically 4-7 days. RLE patients may notice immediate improvement, with vision stabilizing over several weeks.
  • Eye Drops: You’ll be prescribed antibiotic and anti-inflammatory eye drops, which are crucial for healing and preventing infection. Lubricating eye drops will also be recommended to combat dryness, a common temporary side effect.
  • Restrictions: You’ll need to avoid rubbing your eyes, strenuous activities, swimming, hot tubs, and eye makeup for a specified period (ranging from a few days to several weeks, depending on the procedure and your surgeon’s advice). Screen time should be limited initially, gradually increasing with breaks.
• Follow-up Appointments: Regular post-operative check-ups are essential to monitor your healing progress and ensure your eyes are recovering as expected. These typically occur within 24-48 hours, then at one week, one month, three months, and six months, or as advised by your surgeon.
• Long-Term Stability: While vision improves rapidly, full stabilization can take several weeks to months. Most patients achieve excellent vision, often 20/20 or better. The results of refractive surgery are generally permanent, offering a lasting solution to vision correction.
