Vision Correction

Vision Correction

There are two approaches to correcting vision. 

Option 1: 
Laser surgery involving changes to the cornea - also known as laser vision correction. 

Option 2:
Removal of your own natural lens and replaced with an implant, referred to as refractive lens surgery.
B) Additive lens surgery, such as ICL (internal contact lens) or Raindrop. 

All surgical procedures, diagnostics and laser treatments are carried out at Drayton House in Southport. You will receive the most comprehensive screening and diagnostic tests available. 

Our state-of-the-art equipment provides detailed information about the condition of your eyes. We will talk you through every stage of the treatment to give you complete reassurance.

Option 1 - Laser Vision Correction

This works by re-shaping your cornea to correct the focus (The cornea is the transparent outermost layer that covers the iris, pupil and front of the eye). 

Within laser vision correction, there are several options available and your suitability for these options will be discussed in depth during assessment with your Consultant Ophthalmologist. 

Correction is possible for: 

  • Short sight 
  • Long sight 
  • Irregular focus (astigmatism) 
  • Reading vision (presbyopia) usually from the age of 45 

The procedure takes only a minutes and generally both eyes can be corrected on the same day.


Lasik is just one form of laser vision correction. It is the most commonly performed procedure for laser eye surgery today. It is very safe and takes just a few minutes to perform using eye drops only to numb your eye. A flap of the cornea is created before laser ablation, with either a blade or femto second laser. Lasik can correct short sight, long sight and astigmatism. 


• After 3-6 hours your sight will begin to improve.
• By the day after surgery, you should be able to see well enough to work and drive a car.
• Hardly any discomfort during surgery
• Wide range of correction from +3 to -6 dioptres
• No more expensive glasses or contact lenses.


This is rapidly becoming the preferred choice, for creating the corneal flap, in patients seeking vision correction. This specialised laser offers unprecedented levels of safety, precision and comfort which results in the best possible visual outcome for you. 


• Blade Free reduces complications associated with using blade
• Makes a very neat thin flap with consistently accurate depth
• Leaves the corneal surface smooth and dry leading to better vision
• Freedom from glasses


Surface laser treatment, or LASEK is often performed on patients whose cornea is too thin for LASIK. 

Anaesthetic drops will be used to numb your eye during surgery. Visual recovery is slower than for LASIK. Once the surface cell layer has healed, your vision will start to improve. Most patients require a few days off work after surgery. Often a temporary contact lens is put in place to protect cornea and minimise discomfort.


An additive corneal procedure which involves inserting a lens under the flap, made by a Femto Second Laser. Usually performed on one eye to provide reading vision without need for glasses. 

For further information, please call one of our private patient co-ordinators.


This is a new procedure using a femto second laser, where a thin “lens-shaped” pattern is created under the corneal surface. This lens shape is removed through a small incision created by the laser. The dimensions are tailored to correspond to your prescription, and most combinations of short-sight and astigmatism can be corrected. 

Visual recovery is slower than for LASIK, but most patients are able to return to work within a week of SMILE.

Option 2 - Refractive Lens Surgery

Refractive lens surgery, as with other eye surgeries, has a number of options depending upon your suitability. It is especially suitable If your consultant has said you are not suitable for laser eye surgery.

This procedure is suitable for: 

• Myopia
• Hypermetropia
• Astigmatism
• Presbyopia 

We exchange your own natural lens for a special refractive lens which will correct all of the above conditions to suit your lifestyle. The options available to you will be discussed during the consultation with your surgeon. 


• No need to wear glasses or contact lenses
• The lens cannot be seen or felt
• A replacement for your natural eye and is designed to last the rest of your life
• Greater clarity of vision
• Sharper focus at multiple distances



If you have been told you that you’re unsuitable for laser surgery but you still wish to get rid of your glasses or contact lenses, we can offer the option of implantable contact lenses. This option lets you keep your own natural lens and adds an internal contact lens on top. 

These lenses are positioned inside the eye, between the iris and the natural lens. They are specifically designed to correct short sight, long sight and astigmatism. 


• Less dependent on glasses or contact lenses
• The lens cannot be seen or felt
• You retain your own natural lens
• Greater clarity of vision
• Instant results
• Short recovery period



This is another option available to patients at iSIGHT. It is a procedure used to treat distance vision and presbyopia (which affects our inability to focus on near vision, such as reading a book, sewing, using the computer. Presbyopia usually happens around the mid 40’s). 

As the name Duet suggests, the lens is in two parts, unlike a normal multifocal lens implant. One implant corrects your spectacle prescription for distance and the other provides the multifocal element. 

We are sometimes asked “what if I don’t like the multifocal lens implant?” With duet, the process of removing the multifocal element is very simple - we leave the standard implant inside your eye, and just remove the multifocal element.
