What causes blurred vision?
Normally the image of a distant object is focused onto the retina at the back of the eye by the cornea and the lens. The retina, in turn, converts this image into electrical impulses which the optic nerve transmits to the brain. Not everyone though enjoys perfect vision and there are four main causes:
This means that you can see clearly close up but you may find that objects in the distance are blurred. In this case there will be a minus sign (-) in the ‘sphere’ part of your prescription. You will probably need to wear your glasses all the time or for many everyday activities including driving, watching TV or sports.
This means that close up objects (although sometimes objects in the distance too) may be out of focus. In this case there will be a plus sign (+) in the ‘sphere’ part of your prescription. You may need glasses for reading, using a computer, driving, watching TV or sports.
This occurs when the curvature of your eye is not perfectly round. In this case there will be numbers recorded in the ‘cylinder’ and ‘axis’ parts of your prescription. Your vision could be blurred at all distances and, depending on the amount of astigmatism, you may need to wear your glasses all the time.
Presbyopia (the need for wearing reading / near vision glasses)
This occurs when the natural lenses inside your eyes lose some of their flexibility so that it becomes difficult to focus on close-up objects. Presbyopia is a result of the eye’s ageing process and it affects everyone from their mid-40’s onwards. In this case there will be a figure in the ‘near’ or ‘intermediate’ part of your prescription and you will probably need glasses for reading.
Although laser treatment cannot correct presbyopia, allowances can be made for it by focusing one eye for distance vision and the other eye for near vision. This is known as monovision and more information about this can be found by visiting our website http://www.visualase.com/laser-eye-surgery/key-questions
Is laser eye correction suitable for me?
To determine your suitability you will be invited to the clinic for a thorough assessment and consultation.
On arrival in reception you will be asked to complete a simple background questionnaire. The assessment part of the process is conducted by one of our experienced optometrists. Here we will check your prescription and take some very detailed measurements of the anatomy of your eyes. The optometrist will measure your pupil size, your corneal thickness and will also take some images of the front surface of your eyes. It is this information that will allow the ophthalmologist to decide if you are suitable.
Once you have had your assessment you will be brought back through to reception and will then go on to meet your ophthalmologist. This is the doctor who will ultimately treat you, should you be suitable and you are happy to proceed. The ophthalmologist will examine your eyes and review all the information gathered by the optometrist.
Please use this valuable time with your doctor to ask any questions you may have. There is no pressure at all for you to make a decision there and then. The purpose of the assessment and consultation is purely to determine your suitability so you can make an informed choice if you want to go ahead. We take no deposits from you and you will receive no follow up ‘sales’ calls.
You may be suitable for more than one type of treatment, which your ophthalmologist will discuss with you.
How does laser eye surgery work?
Lasers used in vision correction produce precise pulses of UV light energy which are delivered accurately onto the cornea. This energy weakens the bonds between atoms in the cornea so that microscopic amounts of tissue are removed in a process called cool ablation. Since little or no heat is produced, no damage is done to the adjacent tissue allowing the computer guided laser to generate a new corneal profile as it sweeps back and forth across the eye. Myopic eyes are given a flatter profile, hyperopic eyes are given a steeper profile and astigmatic eyes have their profile made more uniform.
There are two types of laser eye surgery:
LASIK - laser in situ keratomileusis
LASIK is by far the most popular treatment due to the speed of visual recovery. In LASIK, an instrument called a microkeratome is used to form a flap on the surface of the eye which is thinner than a human hair. The laser treatment is applied to the exposed corneal tissue and then the flap is repositioned. The cornea has amazing bonding properties and almost immediately the flap adheres to the underlying tissue and begins to heal.
LASEK - laser epithelial keratomileusis
In LASEK the surface layer of cells, known as the epithelium, are displaced and then the laser treatment is applied. The displaced epithelial ‘flap’ is then put back in place and a plain contact lens put on the eye to help with the healing process. This contact lens stays in place until we remove it approximately three / four days later.
Our leading edge technology includes a Wavelight Allegretto Eye-Q laser which is recognised as one of the most advanced laser systems for refractive surgery. A 400Hz ablation rate makes the Eye-Q one of the fastest lasers in the world and its unique PerfectPulse Technology ensures safety and accuracy in combination with outstanding visual results.
Aside from the ability to perform Wavefront Optimised™, wavefront-guided or topography-guided treatments, the Eye-Q features Custom Q, the first treatment module that allows the customization of corneal asphericity. The WaveLight customisation toolkit comprises several different treatment types that can be combined with the laser systems and diagnostic devices to maximise the results for the patient.
WaveLight is a pioneer in wavefront research. The very first wavefront-guided treatment ever was performed with a WaveLight device.
Standard treatments that do not take the natural aspheric shape of the cornea into consideration induce spherical aberrations.
WaveLight lasers are the only systems to use Wavefront Optimised™ ablation profiles as part of their standard treatments. This prevents or reduces the induction of spherical aberrations, resulting in better night vision and less sensitivity to glare.
The natural shape of the human cornea is aspheric. This means that all light rays meet in one sharp focus point.
Therefore the WaveLight laser systems perform an ablation with the objective to maintain a natural post-operative corneal shape, thereby preserving the cornea’s asphericity.
Every treatment is customised to the patient's individual refraction and corneal curvature, by taking the eye curvature into consideration.
Ultra Fast Eye-Tracking
Using a fine laser beam at high speed, the WaveLight laser systems rely on their synchronous, video-based, active eye-tracker to follow even the fastest eye movements, with a response time of less than six one thousands of a second!
As a pupil-based system, it tracks pupils between 1.8mm and 8.0mm, while the automatic centring mode ensures perfectly centered ablations.
The closed loop tracking mode reconfirms the eye’s location again before a pulse is placed on the cornea to ensure that every pulse goes into the desired location.
To monitor the patient’s eye, the active eyetracker utilises three infrared light sources to clearly detect the contrast between pupil and iris.
Perfect Pulse Technology
WaveLight laser systems apply PerfectPulse Technology to ensure safe and precise work at high speed.
PerfectPulse Technology simply means that every laser pulse is completely controlled from its generation to the point when it contacts the cornea.
Each ultra-thin laser pulse is used to sculpt the corneal surface with the upmost precision.
In order to further enhance the safety and precision of the treatment, PerfectPulse Technology uses advanced high-speed eye-tracking to follow the eye’s fast movements, and to ensure an accurate placement of each laser pulse on the cornea.
During the treatment, the energy stability of every pulse is controlled on the basis of a smart energy control programme, which automatically balances the energy levels to ensure that each laser pulse creates the same accurate result.
