Have your eyes started changing since you turned 45 years old? Have you lost the ability to adjust from distance vision to near vision and find that you now need reading glasses almost all the time? Are you getting frustrated wearing reading glasses or multifocal glasses?
You probably have presbyopia which is the normal ageing process of the eyes and starts happening to everybody around the age of 45-50 years of age. This is when most people experience this notable difference in their vision.
The eye’s lens can change shape (a process known as accommodation) to maintain a clear image or focus on an object as its distance varies.
However, the lens’ ability to change shape declines over time because of a natural loss of elasticity. Presbyopia is the result of these changes and occurs when we reach our 40’s and 50’s. This is why reading glasses become necessary – they provide the extra focusing power required to see near objects.
To diagnose presbyopia, we perform a clinical examination, reading vision assessment and refraction test (a measurement of the eye’s ability to focus).
This enables us to determine how advanced the presbyopia is and the strength of your prescription.
Surgical solutions include:
- LASIK laser vision correction with monovision
Laser vision correction is possible once you get over 45 years of age. With “Mono-vision”, we correct one eye for distance vision, and the other for near vision which allows you to see in the distance and read without glasses. This solution is not for everybody, and we recommend you have a “contact lens trial” with this correction to find out if you can tolerate this visual discrepancy. It’s an excellent, safe and simple solution which some people love.
- Presbyond® (Blended Vision) combined with LASIK
With PRESBYOND® Laser Blended Vision we customise the refraction of both eyes for near and distance, creating a ‘blend zone.’ The blend zone essentially makes it easier for the brain to merge the images of both eyes, thereby achieving binocular vision, e.g. how you get around in your day to day life, with both eyes open and working together.
Presbyond® patients adapt faster, and most are delighted about not having to wear glasses anymore. PRESBYOND® Laser Blended Vision is tolerated by a high number of patients – up to 97 % (world results).
- Clear lens extraction with multifocal lens implants
Lens extraction is the same surgical procedure as cataract surgery but takes place before an actual cataract (lens opacity) has developed. The surgery is invasive, so has some additional risks when compared to laser surgery.
We replace your natural lens with an artificial lens that remains in your eye forever. The new lens technologies are very good and allow you to see well in the distance, intermediate and near.
The visual results of this surgery are excellent. However, it’s important to understand that we cannot replicate the same vision you had when you were younger.
Clear lens extraction with multifocal lens implants is an excellent solution for patients who are over the age of 50 years of age, need glasses for distance and near vision and have otherwise normal eyes.
