How does Presbyond work?
Many people notice changes in their vision as they get older. Reading small print may become harder. You might need to hold your phone further away or rely on reading glasses more often.
These changes are often caused by presbyopia. Presbyopia is a normal part of ageing and affects the eye's ability to focus on nearby objects.
PRESBYOND is a type of laser eye surgery that is designed to help some people with presbyopia. It uses advanced laser technology and a personalised treatment plan to improve vision across a range of distances.
At Eagle Eye Surgeons, every patient receives a detailed eye assessment to determine whether PRESBYOND or another vision correction option may be suitable for their eyes and lifestyle.
Understanding presbyopia
Before learning how PRESBYOND works, it helps to understand what presbyopia is.
Inside the eye is a natural lens. When we are young, this lens changes shape easily to focus on objects that are close or far away.1https://www.healthline.com/health/presbyopia
As we get older, the lens becomes less flexible. This makes it harder to focus on nearby objects. This gradual change is called presbyopia.
Presbyopia usually begins around the age of 40 and continues to progress over time.2https://www.healthline.com/health/presbyopia
Common signs of presbyopia
Many people first notice that they need to hold books or phones further away to read them clearly.
Small print may become blurry, especially in dim lighting. Some people experience eye strain or tired eyes after reading or using digital devices for long periods.
These changes are a normal part of ageing and can happen even if you have never needed glasses before.
What is PRESBYOND?
PRESBYOND is a laser eye surgery treatment developed to help manage age-related near vision changes.
The procedure uses laser vision correction together with a treatment approach known as laser blended vision.
Rather than focusing on only one viewing distance, PRESBYOND is designed to provide a smoother range of vision for suitable patients.3 https://www.healthline.com/health/eye-health/presbyopia-treatment#refractive-surgery
The treatment plan is customised to each patient's eyes using detailed measurements taken before surgery.
What is laser blended vision?
Laser blended vision is the approach used during PRESBYOND treatment.
One eye is adjusted to provide stronger distance vision, while the other eye is adjusted to assist with near vision.
The difference between the eyes is carefully planned so that the brain can combine the images from both eyes into a smooth visual experience.
This blended approach is designed to help patients perform a range of everyday tasks at different distances.
How does PRESBYOND work?
PRESBYOND works by reshaping the cornea using laser technology.
The cornea is the clear front surface of the eye. It plays an important role in focusing light onto the retina at the back of the eye.
During the procedure, the laser changes the shape of the cornea according to a personalised treatment plan.
This allows each eye to contribute differently to vision while still working together as a team.
How the brain adapts
One of the unique parts of PRESBYOND is the way the brain adapts to the treatment.
Although each eye has a slightly different role, the brain learns to combine the images naturally.4https://pmc.ncbi.nlm.nih.gov/articles/PMC10882568/
For many suitable patients, this creates a comfortable range of vision for activities such as reading, using a computer, and seeing objects in the distance.
The way people adapt can vary. Some patients adjust quickly, while others may need more time.
Who may be suitable for PRESBYOND?
PRESBYOND may be suitable for some adults who are experiencing presbyopia and would like to reduce their dependence on reading glasses.
Suitability depends on many factors, including eye health, prescription stability, corneal measurements, and how well the eyes work together.
Not everyone is a suitable candidate for PRESBYOND. Some patients may be better suited to another vision correction procedure.
Why a detailed assessment is important
Before recommending treatment, the eye care team performs a comprehensive examination.
This includes measuring the eyes, checking the health of the cornea, and assessing the patient's vision.
These tests help determine whether PRESBYOND may be suitable and allow the surgeon to create a personalised treatment plan.
Patient safety is an important part of every assessment.
What happens during the procedure?
PRESBYOND is usually performed as a day procedure.
Before treatment begins, numbing eye drops are placed into the eyes to help keep the patient comfortable.
The laser reshapes the cornea according to the personalised treatment plan. The procedure itself is generally quick, although patients should allow extra time at the clinic for preparation and post-treatment checks.5https://pmc.ncbi.nlm.nih.gov/articles/PMC10882568/
What is recovery like?
Recovery experiences vary from person to person.
Some patients notice changes in their vision soon after treatment, while others experience gradual improvement over the following weeks.6https://pmc.ncbi.nlm.nih.gov/articles/PMC10882568/
Patients are usually prescribed eye drops and given instructions to support healing.
Follow-up appointments allow the surgeon to monitor recovery and answer any questions during the healing process.
What are the possible benefits of PRESBYOND?
Some patients choose PRESBYOND because they would like greater freedom from reading glasses during daily activities.7https://pmc.ncbi.nlm.nih.gov/articles/PMC10882568/
The treatment is designed to improve vision across different distances by helping the eyes work together more effectively.
Potential benefits vary between individuals and depend on many factors, including prescription, eye health, and healing.
Understanding risks and limitations
Like all medical procedures, PRESBYOND carries potential risks and side effects.
Some patients may experience dry eyes, glare, halos, or temporary changes in vision during recovery.8https://pmc.ncbi.nlm.nih.gov/articles/PMC10882568/
No procedure can guarantee perfect vision or complete freedom from glasses. Some patients may still require glasses for certain activities after treatment.
Your surgeon can explain the possible benefits, risks, and limitations during your consultation.
How is PRESBYOND different from standard LASIK?
Standard LASIK is commonly used to correct short sightedness, long sightedness, and astigmatism.
PRESBYOND is specifically designed to help manage presbyopia and age-related near vision changes.
The treatment uses laser blended vision rather than correcting both eyes in exactly the same way.
Choosing the right treatment
There is no single laser eye surgery procedure that is right for everyone.
The most suitable option depends on factors such as age, prescription, eye health, and lifestyle.
A detailed consultation allows the surgeon to recommend the treatment that best matches each patient's individual needs.
Why personalised care matters
Every patient's eyes are different.
Some people spend most of their day reading or working on computers. Others may spend more time driving or enjoying outdoor activities.
Understanding your lifestyle and visual goals helps the surgeon develop a treatment plan that is tailored to your needs.
A personalised approach supports informed decision-making and helps patients understand what outcomes may be realistic.
Asking questions during your consultation
A consultation is the ideal time to ask questions about the procedure, recovery, possible risks, and expected outcomes.
Understanding your treatment options can help you make a confident and informed decision.
Your eye care team will explain each step of the process and discuss whether PRESBYOND may be suitable for your eyes.
Take the next step
If you are noticing age-related changes in your vision and would like to learn more about PRESBYOND, the first step is a comprehensive eye assessment.
At Eagle Eye Surgeons, patients receive personalised recommendations based on their eye health, prescription, and vision goals.
The best way to begin your journey is to take a suitability self test and find out whether PRESBYOND or another vision correction option may be suitable for you.
