Presbyopia, a common age-related condition, often makes it challenging to focus on close objects, leading to the frequent use of reading glasses. Symptoms of presbyopia include difficulty reading or focusing on objects close up and headaches or sore and tired eyes.
For individuals seeking a long-term solution to this issue, blended vision laser eye surgery offers an option to improve both near and distance vision. Using advanced techniques such as PRESBYLASIK Laser Blended Vision, this procedure reshapes the cornea to potentially enhance depth perception and visual acuity.
This article explores how blended vision laser eye surgery works, its potential benefits, and important considerations to determine if it may be suitable for your needs.
What is Blended Vision Laser Eye Surgery?
Blended vision laser eye surgery, also referred to as PRESBYOND Laser Blended Vision, is a type of refractive surgery designed for individuals with presbyopia.
Unlike traditional laser eye surgery, which primarily addresses a single focus distance, this technique corrects both near and far vision by creating a blend zone in the cornea.
How It Works:
- Dominant Eye for Distance Vision: The procedure adjusts the dominant eye to focus on distant objects.
- Non-Dominant Eye for Near Vision: The non-dominant eye is adjusted for close-up tasks like reading.
- Blend Zone: The cornea is reshaped to allow the brain’s visual system to merge input from both eyes, ensuring seamless focus across different distances.
PRESBYLASIK: A Modern Approach to Presbyopia Treatment
PRESBYLASIK is an advanced form of blended vision laser eye surgery that leverages the brain’s ability to adapt to changes in vision.
By extending the depth of focus, PRESBYLASIK may provide clearer vision at varying distances without the need for significant adjustments or additional treatments.
Features of PRESBYLASIK:
- Customisable: Tailored to each individual’s visual system, ensuring optimal outcomes.
- Preserves Depth Perception: Balances near and distance vision while maintaining natural depth perception.
- Minimally Invasive: Unlike lens replacement surgery, it does not involve implants or removal of the natural lens.
Who is Suitable for Blended Vision Laser Eye Surgery?
This procedure is typically recommended for:
- Individuals aged 40-65 experiencing presbyopia.
- Those with good overall eye health and stable vision.
- People seeking a long-term reduction in dependence on reading glasses or contact lenses.
It may not be suitable for individuals with certain eye conditions, such as severe dry eyes, advanced glaucoma, or retinal issues. A comprehensive consultation, including an evaluation of the dominant eye, corneal tissue, and medical history, is essential to determine eligibility.
How Blended Vision Laser Eye Surgery Works
Step 1: Pre-Surgery Assessment
A thorough eye examination is conducted to assess:
- The health of the cornea and natural lens.
- The dominance of each eye for distance vision and near vision.
- The degree of presbyopia and other refractive errors.
Step 2: Reshaping the Cornea
The laser is used to reshape the corneal tissue, creating a seamless transition between near and far vision.
Step 3: Post-Surgery Adaptation
The brain’s visual system adapts to the new focus points, merging input from both eyes to create clear, comfortable vision at all distances.
Potential Benefits of Blended Vision Laser Eye Surgery
Improved Reading Vision
By enhancing the eye’s ability to focus on close objects, this procedure may reduce reliance on reading glasses for tasks like reading or using digital devices.
Maintained Distance Vision
The dominant eye retains sharp focus on distant objects, potentially making it ideal for activities like driving or sports.
Preserved Depth Perception
The blend zone allows the brain to maintain natural depth perception, potentially allowing for smooth transitions between near and far vision.
Minimally Invasive
The procedure involves reshaping the cornea rather than implanting devices, potentially reducing risks and recovery time compared to lens replacement surgery.
Long-Term Solution
While presbyopia progresses with age, blended vision surgery may provide sustained improvements in both near vision and distance vision for many years.
Potential Considerations
- Adaptation Period: It may take a few weeks for the brain to fully adapt to the new focus points.
- Temporary Dryness: Some patients experience mild dryness after the procedure, which can be managed with lubricating eye drops.
- Side Effects: Some other potential side effects include glare, halos or visual disturbances.
- Scope of Correction: This approach focuses on near vision and may not address other refractive errors to the same extent.
- Follow-Up Care: Regular check-ups are necessary to monitor the healing process and ensure optimal results.

FAQs
What is blended vision laser eye surgery?
Blended vision laser eye surgery is a specialised procedure that uses an excimer laser to reshape the cornea, enhancing the eye’s ability to focus on both near and distant objects. In terms of what laser blended vision offers, the surgery creates a “blur zone” that allows the brain to integrate visual input from both eyes. This approach aims to provide clear, balanced vision with less reliance on glasses and contact lenses.
Can blended vision laser surgery correct both near and distance vision?
Yes, this procedure is designed to improve both near vision and distance vision by creating a balance between the dominant eye and the non-dominant eye. By reshaping the cornea with an excimer laser, it forms a “blur zone” to enhance the brain’s ability to adapt, allowing a natural transition between distances.
How does laser blended vision surgery compare to glasses and contact lenses?
Unlike glasses and contact lenses, which provide temporary solutions to presbyopia, blended vision laser surgery offers a long-term approach by reshaping the cornea. This eliminates the need to switch between corrective lenses for different distances and enhances the eye’s natural focusing ability.
Is blended vision laser surgery safe and how long is the recovery?
Blended vision laser surgery is a safe and effective option for most patients. The use of an excimer laser ensures precise reshaping of the cornea. Recovery is typically quick, with improved vision noticeable within a few days. Temporary effects, such as mild dryness or glare, may occur but resolve with proper aftercare, including lubricating eye drops.
