Presbyopia (also known as age-related, up-close reading vision loss) refers to the gradual loss of your eye’s ability to focus on nearby objects, which usually worsens with age. This eye condition starts to become more noticeable around age 40.
Presbyopia is characterized by difficulty focusing on objects that are close-up.
For instance, you may discover you have presbyopia when you need to hold a book or menu an arm’s length away from your face in order to read it.
The symptoms of presbyopia can be managed through the use of glasses and contact lenses. But this comes with disadvantages. For example, it’s easy to forget to take your reading glasses with you and it’s also a pain to constantly have to pull them out, adding extra steps to your everyday routine.
This is why many people choose to undergo a vision correction surgery in order to correct their presbyopia because of the convenience and freedom it offers.
What Causes Presbyopia?
Presbyopia is caused by age, and most people struggle with it later in life. This condition occurs when the eye’s lens (the transparent structure located at the back of the eye) begins to harden and lose elasticity, which happens with time. This, in turn, prevents it from changing shape to focus on close-up images, resulting in the images appearing out of focus.
Symptoms of Presbyopia
One of more of the following symptoms can indicate presbyopia:
- A need for brighter or more light
- Increasing font size on your device
- Squinting or straining to read fine print
- Blurry vision at normal reading distance
- A need to hold reading material father away
- Eyestrain, headaches after doing close-up work
Lens PresbyVisionTM is a type of Refractive Lens Exchange (RLE), which occurs when the eye’s clear, natural lens is replaced with an artificial intraocular lens (IOL). It is designed to correct refractive problems as well as achieve sharper focus and clearer vision at all distances, thereby reducing or eliminating your need for contact lenses and glasses, including bifocals. Lens PresbyVisionTM also has the added benefit of eliminating the need for future cataract surgery.
Monovision LASIK, also known as Laser PresbyvisionTM, is a specialized technique in which the dominant eye is corrected for distance vision (hyperopia), while the other eye is corrected for near vision (myopia). This allows patients to achieve functional vision for tasks both near and far, since each eye can be corrected to improve vision at different distances.
