Presbyopia, also known as rabun tua in Malay, is a natural aging process that typically begins around age 40. Similar to a camera lens, the eye uses the cornea and lens to focus light onto the retina, creating clear images. Over time, the lens loses flexibility, making it harder to focus on objects at different distances. This often results in the need for reading glasses or contact lenses. Presbyopia can also occur alongside other vision issues like nearsightedness, farsightedness, or astigmatism. Fortunately, various treatments can help people see clearly at all distances.
ZEISS PRESBYOND Laser Blended Vision represents a significant leap forward in corneal refractive surgery. Utilising natural eye aberrations and cutting-edge software, this method integrates with the ZEISS MEL® 90 excimer laser to deliver precise binocular vision correction. This approach ensures clear focus at various distances while maintaining high visual quality.
Monovision is a conventional treatment where one eye is corrected for distance vision and the other for near vision. While this method can be effective, it requires the brain to adjust to seeing two images at different distances. Many patients find it challenging to adapt, and studies show only 59 - 67% of patients successfully merge the two images. Common issues include compromised vision in the intermediate range and a significant adjustment period.
Laser Blended Vision offers a customised treatment that provides clear vision at all distances.
Unlike traditional monovision, this method uses binocular vision to fine-tune the depth of field for each eye, creating a “Blend Zone” that smooths the fusion of images in the intermediate range. Benefits include:
Laser Blended Vision is ideal for those with busy, active lifestyles who find reading glasses inconvenient. It is also effective for patients with presbyopia and other refractive errors such as myopia, hyperopia, or astigmatism. Assessment for Laser Blended Vision includes:
Consider hobbies, daily activities, and other factors that may influence the decision.
Evaluates refractive error(s), corneal curvature and thickness, and tests tolerance for monovision and ocular dominance.
Your eye doctor will provide personalized advice on whether Laser Blended Vision is the right treatment for you.
Before the treatment, anesthetic eye drops are applied to ensure a painless procedure. An eyelid holder is used to prevent blinking during the surgery.
