Optimised visual acuity at all distances for patients with presbyopia
Laser Blended Vision
Have your eyes started changing since you turned 45 years old?
Have you lost the ability to adjust from distance vision to near vision and find that you now need reading glasses almost all the time?
Are you getting frustrated wearing reading glasses or multifocal glasses?
You probably have Presbyopia which is the normal ageing process of the eyes and starts happening to everybody around the age of 45-50 years of age. This is when most people experience this notable difference in their vision.
Due to medical and technological research in recent years, correction options are available. One of these options is Laser Blended Vision, an advanced Laser Vision Correction procedure for compensating some of the symptoms of presbyopia. It offers several advantages over conventional methods, particularly with respect to the customisation of treatment, focused vision at all distances and the immediate impact it provides.
Bringing it into focus
When we are young, the lens of the eye can change shape to focus on objects at different distances. As we age, the lens becomes less flexible and starts losing its ability to change shape and to adjust its focus. As a result, we have difficulty seeing clearly at all distances and eventually require reading glasses or contact lenses.
Through the increasing inflexibility of the lens and other biomechanical changes within the eye, the light rays cannot be focused on the focal point of the retina. As a result, objects appear out of focus. Presbyopia can occur in conjunction with other refractive errors such as near-sightedness, far-sightedness, astigmatism and even normal vision. Fortunately, there is a variety of methods that can help people with presbyopia to achieve sharply focused vision.
Comparing Laser Vision Correction options
Most conventional treatment methods – surgical treatments as well as contact lenses – use the principle of monovision: one eye is corrected for distance and the other eye for near vision. The brain must adjust to seeing two images corrected for different distances. Unfortunately, some patients are unable to get used to the procedure. Patients frequently experience an area of compromised vision in the intermediate range – the Blur Zone. Those patients that are able to tolerate the procedure often require some time to adjust to their new eyesight.
Laser Blended Vision
By comparison, Laser Blended Vision offers a variety of extra advantages – specifically, customised treatments that result in sharply focused vision at all distances. With this technique, one eye is treated to view objects mainly at distance, but a little up close, and the other is treated to view objects mainly up close, but a little at distance. The brain puts the two images together and enables the individual to see distance and near without effort. In most cases, the brain is able to compensate, and you will experience an excellent depth of focus and overall visual acuity, without the need to wear glasses or contact lenses.
The unique Blend Zone makes it easier for the brain to maintain its binocular vision by merging the images of both eyes for your normal 3D vision. Most patients experience an immediate improvement.
Finding the right option
Is Laser Blended Vision right for you?
Laser Blended Vision is especially well suited for people with a very busy and active lifestyle who often find having to use reading glasses inconvenient. Laser Blended Vision is effective for treating patients with presbyopia who also have other refractive errors like myopia, hyperopia or/and astigmatism.
In order to find out if Laser Vision Correction is right for you, your personal vision requirements and expectations are taken into consideration. That is why you will have to answer questions about your hobbies, your daily activities and other aspects that might affect the decision.
As the Laser Blended Vision treatment is customized for each patient, you will also have to undergo a detailed eye examination. The nature and degree of your refractive error(s), curvature and thickness of the cornea, as well as many other factors play a role.
Your tolerance level for monovision and ocular dominance will also be tested. You may require a contact lens trial having contact lenses simulate the vision we are hoping to achieve with Laser Vision Correction and giving you an opportunity to see if it’s right for you.
Performing the procedure
Laser Blended Vision at a glance
• Age-optimised Laser Vision Correction for people with presbyopia
• Based on an established LASIK treatment
• True binocular vision thanks to the unique Blend Zone
• Generally clear sight at all distances: near, far and even intermediate
• Customized approach – individual treatment profile for each patient
Laser Blended Vision treatment steps
Step 1 – Creating the flap
A flap is created with a
hightly precise femtosecond laser.
Step 2 -Relocationg the patient
The patient is moved from the
femtosecond laser to
the MEL90 excimer laser.
Step 3 – Folding back the flap
The flap is gently folded back
exposing the inner corneal tissue
to be treated.
Step 4 – Correcting the error
The MEL90 excimer laser reshapes
the corneal tissue correcting
the refractive error.
Step 5 – Repositioning the flap
The flap is returned to its original
position, protecting the eye like
a natural bandage.
FAQ’s about LASER BLENDED VISION – PRESBYOND
Laser Blended Vision is special. Why?
With Laser Blended Vision, the treatment is customized for each eye. thereby, an overlapping zone (blend zone) in the intermediate range is created. It makes it easy for the two eyes to merge the images for normal binocular vision and enables sharply focused vision at all distances.
How long will it take before I can see properly and can return to my normal routine?
Every healing process is different. In most cases, visual sharpness is already very good one or two days after the surgery. Your new vision normally stabilizes within two to three weeks.
Will I be able to see clearly at all distances with each eye?
With Laser Blended Vision, one eye is corrected for full distance vision and some mid-range vision, and the other eye is corrected to focus at the mid and near range. As a result, you won’t be able to see sharply at all distances if you use just one eye. With both of your eyes, however, you will achieve sharply focused vision at all distances.
What is the time interval between surgery for each eye?
Usually, both eyes are treated the same day. That way, patients can fully experience the benefits of the method.
What follow-up examinations may be necessary?
After surgery, you will be given drops and/or other medication. Your first check-up is usually the day after the surgery. Further examinations are generally conducted at regular intervals for the following weeks until your new vision has stabilised.
