Laser Eye Surgery For Very High Prescriptions
One of these myths in the Laser Eye Surgery world is that the treatment is not an option for those with very high prescriptions, with the only option on the table being synthetic lens implants.
Not too long ago, this used to be the case. If you wanted to free yourself from glasses or contact lenses, then you could opt to have an artificial lens implanted to replace your eye’s faulty natural lens or an additional lens implanted in front of the existing lens, called an ICL, to correct it.
Even today, this is still the only option at many clinics. However, this is usually a matter of the clinic lacking the technology or expertise to treat very high prescriptions. Today, the belief that the only way to treat high prescriptions is with synthetic lenses is nothing but an old-world myth.
The short answer is that, at London Vision Clinic, we can treat very high prescriptions with ReLEx SMILE as it employs a keyhold surgery approach to reduce the amount of the eye that needs to be removed.
The age of high prescription treatments
For almost a decade now, we’ve been treating patients with very high prescriptions. We’re able to do this due to a combination of world-class technology, the expertise of our surgeons, and the fact we believe in giving every patient the best possible outcome.
Our pioneering approach to developing High Profile treatments has established London Vision Clinic as world-leaders in treating very high prescriptions.
To give you an idea of where the rest of the industry is at, Professor Dan Reinstein, lead laser eye surgeon at London Vision Clinic, says that “generally speaking, traditional Laser Eye Surgery can only correct prescriptions up to a maximum of between -8 and -10.”
This is because in LASIK to get to the corneal bed and remove refractive errors, the surgeon cuts a circular flap in the surface of the eye — a bit like creating a doorway to the underlying tissue.
The higher the refractive error (i.e. higher prescriptions), the more tissue needs to be removed to correct it. Therefore, the cornea must be thick enough to allow the procedure to occur. Most people don’t have thick enough corneas to allow the necessary reshaping to correct high prescriptions – making them unsuitable for conventional LASIK treatment.
However, it is only one of several options available. When it comes to treating high prescriptions, at least at London Vision Clinic, we have the revolutionary ReLEx SMILE treatment. With ReLEx SMILE, people with thinner corneas and who have prescriptions of higher than -10 can be treated simply because, with ReLEx SMILE, there is no need to make a flap in the corneal surface.
Instead, we remove the tissue from the centre of the cornea through a tiny hole made at the side of the eye, leaving the front of the cornea intact—a little bit like keyhole surgery.
To do this, SMILE uses a precise laser to create micro-pulses beneath the cornea’s surface. The patient feels virtually nothing during the surgery, thanks to anaesthetic eye drops and the fact that contact with the eye is minimal and gentle.
What’s more, thanks to the minimally-invasive technique, SMILE can significantly reduce or even eliminate the side-effect of post-operative dry eye, which people often experience temporarily after traditional Laser Eye Surgery.
