BEYOND 45 YEARS OF AGE YOUR NEAR VISION BECOMES INCREASINGLY BLURRED
In these toggles we explain what you need to know about presbyopia
Presbyopia occurs naturally with increasing age and is typically noticed as we enter our mid-40s.
Near vision becomes more blurred, and we hold material further away to read it. Soon afterwards, we may need to start using reading glasses.
Watch this video on presbyopia:
The eye’s lens can change shape, allowing it to focus light on the retina. It adjusts depending on where the light is coming from. If the light is far away, the lens becomes thin. If the light is near, the lens becomes thick. This process is called accommodation and is strongest in early life.
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 is noticed 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.
Presbyopia also results from cataract surgery where a monofocal lens implant is used.
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.
The most appropriate treatment option for you will depend on several factors. These include:
- Your exact spectacle prescription
- The precise clinical examination findings
- Your age
- Your job
- Your hobbies
- If you have any other eye conditions or issues
Glasses and contact lenses
Presbyopia is usually treated by opticians in the first instance by the use of prescription reading glasses.
Some patients decide to use multifocal contact lenses, or single vision contact lenses with one eye focused for distance and the other eye focused for near (also known as monovision).
Refractive lens exchange (RLE)
After a while, some patients grow weary of needing reading glasses or find them very inconvenient and seek a surgical option to provide good vision for distance and close-up without the need for glasses. This is where Prof Muhtaseb can help.
Treatment options will typically include refractive lens exchange (RLE) with a choice of lens implants.
By understanding your lifestyle requirements, Prof Muhtaseb is able to explain the various lens implant options and the benefits of each. By involving you fully in the decision-making process, he will recommend a personalised treatment plan.
What happens if I have developed a cataract?
Patients that undergo cataract surgery with a monofocal lens implant also need to use reading glasses to see clearly at near distances. We can reduce this dependence on reading glasses by opting for a multifocal lens implant at the time of initial surgery.
Watch this video on correcting presbyopia with Refractive Lens Exchange:
What Happens in Cataract Surgery / Lens Extraction?
When the natural lens becomes cloudy with time, this is called a cataract. During cataract surgery, the natural lens is removed and replaced with a clear plastic lens.
This new lens is monofocal and is best able to focus light on the retina from one distance. Spectacles are then required to see clearly at other distances.
Usually, patients like to see clearly in the distance and use spectacles for intermediate (computers, painting, sheet music) and near (reading) work. However, there are some exceptions.
If you are considering cataract surgery or refractive lens exchange, but don’t want to rely on glasses to read afterwards, you should consider the choosing a ‘premium’ lens to reduce your reliance on glasses for reading and other ‘near vision’ activities. Such lens implants include multifocal and accommodating lenses.
What are multifocal intraocular lenses?
Multifocal Intraocular Lenses (mIOL’s) employ new technology that mimics the ability of the eye’s natural lens to adjust its shape and so focus light. They create focal points for light coming from far, intermediate and near objects.
It is not usual to implant a different type of IOL in each eye. The eyes most commonly receive the same kind of lens, although we treat each case individually, and we will advise you with your best interests in mind.
Depending on your unique requirements, the same mIOL may be used for both eyes, or we may suggest a “mix-and-match” approach to mIOL implantation.
Multifocal intraocular lenses for astigmatism
If you have astigmatism, we must correct this visual error before or after we implant the multifocal lenses. There are several ways of doing this.
With trifocal, toric form lenses, we can correct your astigmatism in addition to giving you good distance and reading vision. This is all done in one operation and avoids multiple surgeries with higher expenses.
The lens is adorned with lines that mark the axis of astigmatism correction. This allows us to place the lens in exactly the correct orientation in the eye that allows you to enjoy full visual potential at both far and near without glasses.
Is spectacle independence guaranteed if I receive a multifocal IOL?
Medical treatment does not generally carry a guarantee. However, the likelihood that you will need glasses for near work are greatly reduced with a multifocal IOL compared to a standard lens. The vast majority of patients can see well at all distances without using glasses. However, some people may need to wear spectacles for some tasks, such as using a computer, reading for prolonged periods or driving at night.
Is mIOL suitable for everyone?
No medical intervention is suitable for everyone. The overall health of your eyes, your visual requirements, expectations for postoperative vision, and other factors will inform the decision regarding suitability.
Astigmatism may need to be corrected before mIOL implantation, depending on the examination findings.
