- PRESBYOND Laser Blended Vision: Surgery & Treatment
PRESBYOND® Laser Blended Vision is an advanced, customized laser eye surgery designed to treat presbyopia—the age-related loss of near vision that typically begins after age 40. Unlike traditional monovision or reading glasses, this procedure uses a Femto-LASIK technique to reshape the cornea to create a "blend zone" for both eyes, allowing for clear vision at near, intermediate, and far distances. It is used to reduce or eliminate dependency on reading glasses and bifocals.
Summary of PRESBYOND Laser Eye Surgery
- Purpose: Treats presbyopia (needing reading glasses) while correcting existing myopia (near-sightedness), hyperopia (far-sightedness), or astigmatism.
- Procedure: A fast (10-15 mins per eye), painless procedure using a laser to create a "blended" effect. One eye (dominant) is corrected for mainly distance, while the other is corrected for intermediate/near, with a specialized "blend zone" that helps the brain merge images naturally.
- How it Works: Unlike conventional LASIK, PRESBYOND induces natural spherical aberrations to increase the depth of field in both eyes, making the adjustment easier for the brain compared to traditional monovision.
- Recovery: Most patients notice an improvement within 24-48 hours and return to work within 2-3 days.
- Suitability: Ideal for active individuals over 40-45 who want to be spectacle-free.
FAQ
No. Traditional monovision has a sharp transition, often causing a "blur zone" between near and far. PRESBYOND creates a "blend zone," allowing a smooth overlap of vision.
No, the procedure is painless, as numbing eye drops are applied beforehand. Some patients might feel mild pressure during the procedure.
While PRESBYOND is long-lasting, it does not stop the natural ageing process of the eye. However, most patients maintain sufficient reading vision for the rest of their lives. If needed, a follow-up ("enhancement") procedure can be done in the future.
While initial visual improvement is immediate, it can take anywhere from a few weeks up to 4–6 months for the brain to fully neuro-adapt to the new "blended" vision.
Risks are similar to standard LASIK, including temporary dry eyes, light sensitivity, or glare/halos at night.
Yes. Even though the goal is to be spectacle-free, some patients might still need light reading glasses for extremely fine print or very low-light conditions.
PRESBYOND is less invasive because it reshapes the surface of the eye (cornea) and does not remove the natural lens. It also avoids the risk of retinal detachments associated with internal lens replacement surgery.
