Patients who:
I will suggest the best option for you and your lifestyle during our consultation. Below are the several choices that I will most likely discuss with you, to optimise your vision for your lifestyle and ensure a lifetime of excellent vision.
This option provides high quality distance vision but will require glasses for everything up close. It is a great option for people who do not mind wearing reading glasses. This option may suit people with a heavy vehicle licence or have an occupation that relies heavily on clear distance vision. A Monofocal lens is used in this option.
Simulated vision with monofocal lenses. Good distance vision where glasses are needed for computer work and reading
This is where one eye is corrected for distance vision and the other for near vision similar to
Presbyond. This vision is often appreciated by people who only wear reading glasses or for many people who already wear this in their contact lenses. If we decide this is an option for you they may organise a contact lens trial for you to mimic the results of the surgery before proceeding. Monofocal PLUS lenses work exceptionally well in Blended Vision.

This is becoming an increasingly popular option for most of my patients who desire complete spectacle independence. These lenses provide a high level of freedom from glasses and generally give good vision at all distances. They work very differently to multifocal glasses, so don’t be concerned if you have had problems with these in the past. There are a number of different brands of multifocal IOLs, all with slightly different focal points. I will advise you on the best lens for your lifestyle.
Multifocal lenses split light into 3 different focal points
Extended depth of focus (EDOF) lenses is the latest form of intraocular lenses aimed at giving patients spectacle independence. They provide an excellent range of vision from near to distance. For small print reading glasses might still be needed. EDOF has much less nighttime glare symptoms than multifocal lenses with improved contrast or quality of vision.
Simulated vision with EDOF lenses. Excellent distance and intermediate vison with functional near vision
Not everyone is the same and not every patient has the same visual requirements. There are various different lens types available on the market to suit every individual.
I will perform an extensive and comprehensive analysis of your eyes, lifestyle and occupational needs to determine the best lens suited to you as an individual.
I will tailored your lens type to your specific needs and goals.
As a rule of thumb, the more spectacle free a patient wants to become, the more nighttime glare and quality of vision issues a patient will have. This is because as the range of a lens increases, the more extra optical properties a lens has. This can compromise your quality and night time vision.
As the word “mono” (one) implies, monofocal lenses has only one focal point. These lenses can either be focussed for distance vision or near vision in both eyes.
Monofocal lenses as a rule do not cause nighttime glare and halo complications and the contrast sensitivity or quality of vision is not compromised
Example of a clear monofocal lens. These lenses have no extra properties and can either be focussed for distance or near vision- not both
Monofocal PLUS lenses are highly versatile intraocular lenses that induce natural optical properties known as l spherical aberrations to enhance the depth of focus. In other words a single focal point with a little bit of extra range of vision around it.
As these lenses has a range of vision they can be implanted with different focal points in each eye giving patients “Pseudophakic Blended Vision”- very similar to
Presbyond.
Monofocal PLUS lenses do not cause glare symptoms at night and contrast or quality of vision is not affected
Example of a monofocal PLUS lens. These lenses have internal properties which induced natural optical phenomena known as spherical aberrations which enhances the patient’s depth of field
Extended Depth of Focus or EDOF lenses are the most modern type of lenses that can achieve spectacle independence.
EDOF lenses elongates a single focal point and gives an extra range of vision of 1.5-1.9 optical units or more.
These are extremely versatile lenses that can be implanted at various focal points to achieve spectacle independence.
EDOF lenses can also be used for Pseudophakic Blended Vision with an enhanced range with what is possible with Monofocal PLUS lenses.
EDOF lenses do cause night time glare though it is minimal and studies shows that most patients become accustomed to it over time.
Contrast sensitivity or quality of vision is minimally affected by EDOF lenses.

Multifocal lenses give patients distance, intermediate and excellent reading vision without the need for reading glasses.
Multifocal lenses have rings (known as diffractive rings) in the lenses which splits light into 3 focal points, one for distance, one for intermediate and one for near vision. These lenses are general known as Trifocal lenses as they have 3 distinct focal points
With multifocal lenses patients are able to read small text comfortably without the need for reading glasses.
Because multifocal lenses have rings in them, they can cause glare and halo symptoms at night time.
Multifocal lenses are aimed at distance in both eyes.
Due to the rings and light splitting technology, both eyes can see distance, intermediate and near.
The advantage of multifocal lenses is that both eyes do not need to be focussed at different points.
Glare and haloes induced at night time by multifocal lenses
Example of a Multifocal lens with diffractive rings
A Refractive Lens Replacement or RLE is an operation that is similar to a cataract operation but is performed when no cataract is present . An RLE helps you see again without glasses when you’re older than 50 years of age and not suitable for Presbyond or you want a more permanent solution for spectacle independence.
During the RLE I expertly remove your natural clear lens and replace it with a premium artificial lens that will give spectacle independence or significantly reduce dependence on glasses or contact lenses. During an RLE I use the laser to perform precise incisions and create a perfectly round opening in the lens to ensure the most accurate outcome possible.
The artificial lens implant that I will insert in your eye will be chosen from several types of different intraocular lenses on the market. In most cases patients opt for multifocal lenses extended depth of focus lenses or a combination of both to become as spectacle free as possible . The intraocular lens that is chosen is based on each individual patient’s visual needs and I will discuss these options with you during our consultation so you as a patient make an informed decision about the most appropriate lens for your eyes.
Lens Replacement Surgery is done at a day surgery as an outpatient procedure, meaning you will have surgery and return home the same day to recover.
Visual recovery takes 2-3 days in the majority of cases. Patients can drive or fly again after 3 days
Whether you are ready to take the plunge into a world of crystal clear vision, or just have a few questions for me, feel free to drop me a line.

I'm proud to have earned glowing reviews from patients who I've helped own their vision allowing them to enjoy a life free from the constraints of glasses and contact lenses. I'm humbled by the the overwhelming positive online reviews on Google.
