Presbyopia
Presbyopia is an age-related vision issue that typically begins around the age of 40 and gradually worsens over time. When the lens inside the eye deteriorates, hardens, and loses its elasticity, its ability to adjust focus diminishes, much like a camera with a malfunctioning autofocus, making it difficult to see objects clearly up close. However, presbyopia is not an eye disease but a natural physiological phenomenon. Understanding the causes of presbyopia and how it works can help in choosing the right treatment to improve near vision and enhance the quality of life.
Presbyopia Symptoms
1. Difficulty in reading small print at close distances, such as reading books or mobile screens.
2. Easily experiencing eye strain and headaches.
3. Needing to hold objects farther away to see them clearly.
4. Requiring brighter lighting for close-up work.
5. Frequently blinking or rubbing the eyes in an attempt to improve focus.
Difference between Presbyopia, Hyperopia, and Myopia
Presbyopia differs from other vision problems such as myopia, hyperopia, and astigmatism because it is related to changes in the structure of the eye's lens rather than changes in the shape of the eyeball or the curvature of the cornea.
In normal vision, the eye can naturally adjust its focus to present clear images of objects at both near and far distances on the retina.
Presbyopia differs from other vision problems (myopia, hyperopia, and astigmatism) as it is linked to aging and lens degeneration rather than the length of the eye axis.
Hyperopia causes close-up objects to appear blurry while distant objects may appear clearer. This condition occurs when the eyeball is too short, causing the eye's focus to fall behind the retina rather than precisely on it.
Myopia causes distant objects to appear blurry while close-up objects may appear clearer. Myopia results from an elongated eyeball, causing the eye's focus to fall in front of the retina rather than directly on it.
Presbyopia Treatments
Lens Replacement Surgery
Lens replacement surgery is a minimally invasive procedure where the patient’s deteriorated lens is removed and replaced with a suitable artificial lens. It addresses presbyopia, myopia, and hyperopia all at once, eliminating the future possibility of cataracts. This procedure does not require lasers, offers quick recovery, stable and reliable results, and preserves the natural corneal tissue.
- Can correct myopia, hyperopia, astigmatism, and presbyopia simultaneously
- Eliminates future risk of cataracts
- Allows for selection of artificial lenses based on lifestyle needs
- Does not damage the cornea, rarely causes dry eyes
- Possible glare issues
- Surgical risks exist
EVO Viva ICL (ICL V6)
Implantable Collamer Lens (ICL) is an additive vision correction technique that involves implanting corrective lenses directly into the eye through a minimally invasive incision. Using lenses designed for presbyopia (EVO Viva ICL) can correct presbyopia and myopia. The EVO Viva ICL lens features an extended depth of focus design, allowing patients to see clearly at various distances. If needed, the lens can be removed for cataracts or other eye surgeries without altering the eye structure.
- Corrects up to 1800 degrees of myopia and presbyopia
- Reversible technology
- Does not affect future artificial lens choices for cataract surgery
- Does not harm the cornea, rarely causes dry eyes
- Possible glare issues
- Surgical risks exist
Monovision Correction
Monovision correction involves fully correcting the dominant eye for clear distance vision while adjusting the non-dominant eye for near vision. This allows both eyes to see clearly at different distances. Monovision correction can be achieved through laser vision correction (SMILE/SMILE®️pro) or Lasik laser vision correction.
- Clarity at both near and far distances
- Simpler surgical process
- Reduced depth perception
- Surgical risks exist
Reading Glasses/Contact Lenses for Presbyopia
Reading glasses are a common aid for treating presbyopia but do not cure it. They add the appropriate lens power to compensate for the eye's reduced ability to focus on close objects. Reading glasses can be reading glasses, computer glasses, or multifocal glasses, chosen based on personal needs and prescription.
- Convenient and easy to purchase
- A prescription may need updating as presbyopia worsens with age
- Long-term use might cause dizziness

FAQ
-
How to diagnose presbyopia?The diagnosis of presbyopia typically requires a professional eye doctor or optometrist to conduct an eye examination. An eye doctor or optometrist will perform an eye check-up based on your symptoms, including vision tests and examinations of the retina. If you notice blurriness or difficulty focusing on close objects, especially after the age of 40, it is recommended to schedule an eye examination early to determine if you have presbyopia.
-
Does frequent smartphone use accelerate the onset of presbyopia?Extended use of smartphones or other electronic devices may cause eye fatigue, but currently, there is no scientific evidence suggesting that smartphone use leads to presbyopia. However, prolonged screen time may exacerbate the symptoms of presbyopia. To alleviate eye strain, it is advised to take regular breaks and give your eyes rest, as well as stay away from screens for some time.
-
What methods can be used to prevent presbyopia?Presbyopia cannot be completely prevented as it is a natural age-related change. However, you can take measures to slow down its impact, such as maintaining good eye health, following a balanced diet, not smoking, avoiding prolonged smartphone or screen use that can cause eye fatigue, and scheduling regular eye check-ups.
-
What are the differences between presbyopia and hyperopia?Presbyopia and hyperopia have different causes. Presbyopia results from age-related degeneration, while hyperopia is due to the eyeball being too short. Although both affect near vision, presbyopia primarily makes it difficult to see close objects clearly, especially small print; while hyperopia can affect both near and far vision. The causes and symptoms of these conditions differ, thus requiring different treatment methods and vision correction techniques. If you have vision issues, it is advisable to seek evaluation and advice from an eye care professional.
-
How often should one get their eyes checked after being diagnosed with presbyopia?Once you suspect you have presbyopia, it is recommended to seek advice from an eye doctor or optometrist. The doctor or optometrist will provide guidance on the most appropriate frequency for regular eye check-ups based on your situation and needs. Generally, for middle-aged individuals, it is advisable to undergo an eye examination at least once a year, although the specific frequency should be tailored to each person's circumstances.
