1. What is Presbyopia
The human eye is like a camera. After passing through the cornea, the light will pass through the lens. The main function of the cornea and the lens is to refract, focus, and project the image onto the retina to form an image.
Our lens will become harden and get elastic deterioration when we grow old, so that when we see the near objects, our lens cannot get the right focus, and the image becomes blurry.
Presbyopia generally appear in the 40 to 50 years old, it is the phenomenon of natural aging eyes, there is no prevention method at this moment.
2. Early Symptoms of Presbyopia
- Having difficulty reading small print (Blurred vision at a normal reading distance)
- Having eyestrain or headaches after reading or doing close work (especially when the there is insufficient light)
3. Will I have Presbyopia when I have Myopia
Anyone can have the chance of having Presbyopia. No matter what eye conditions they have, like Myopia, Hyperopia, Astigmatism.
4. Treatment Types for PresbyopiaChoices can vary and please consult with your ophthalmologists:
- MonoVision (by Lasik)
- Cataract Procedure to remove Presbyopia
MonoVision Treatment (by Lasik)
By using lasik, one eye (usually the dominant eye) is focused for distance vision, and the non-dominant eye is focused for near vision (e.g. reading books). The difference between the eyes is not too large, many patients adapt to the change after MonoVision.
- Dominant eye is set to focused for distance vision
- Non-dominant eye is set to focused for near to intermediate vision.
- Delay or eliminate the need for reading glasses
- Reading glasses may still be required for prolonged reading or when presbyopia grows with age
Similar to Lasik, PresbyMAX uses Femtosecond Laser or Corneal Lamellar Knife to make a corneal flap. then set off the corneal flap to expose the matrix layer. Unlike traditional LASIK surgery, PresbyMAX undergoes a multifocal state of different areas of the corneal surface. After laser cutting is completed, the corneal flap is restored to its original position.
- PresbyMAX eliminates the need for reading glasses
- Reading glasses may still be helpful for near or distance vision
Cataract Procedure to remove Presbyopia
If you need cataract treatment, you may want to consider presbyopia-correcting intraocular lenses (IOLs) that help improve cataract and presbyopia.
