Improving your Quality of LIFE by improving your Quality of VISION

Cataract Summary

A cataract is a clouding of the eye's natural lens

The only treatment once the cataract is impacting vision significantly is cataract surgery


This lens is inside the eye just behind the pupil and has the ability to focus on objects both far and near while you are young enough. Typically at around age 42-45 years the lens becomes dysfunctional and cannot focus as well any more. This is when people typically get reading glasses, bifocals or varifocal glasses. If the lens starts becoming cloudy, the vision starts blurring and now you have a cataract. The best analogy is thinking of an egg about to be fried in a frying pan. You can see the yellow yolk surrounded by clear material through which you can clearly see the bottom of the pan. This clear material is the closest thing in nature to the natural lens. Once the egg starts frying the clear material becomes white, then yellow and eventually brown / black as the egg cooks. This is exactly the same process occurring in the lens as the cataract becomes less clear and more cloudy. The only treatment currently available for cataracts that are impacting vision is that of cataract surgery and intra-ocular lens (IOL) implantation.

Refractive Cataract Surgery

How to treat cataracts

Cataracts occur when the natural lens inside the eye starts to become cloudy. Once it gets to the point where it is bothering you then cataract surgery can be considered. Modern cataract surgery is safe and besides improving your vision, it can also reduce your dependency on glasses. The first 2 videos on the right show the thought process around cataract surgery and the options available with cataract surgery.

The third video shows Yag-laser capsulotomy for a condition called “After-cataract” or “Posterior Capsule Opacification.” This can occur within weeks to months to years after cataract surgery and takes less than a minute to treat with a Yag laser in the consulting room as an out-patient.

Single focus IOL’s (Focus at one point only) / Monofocal

For short-sighted patients, if both eyes are targeted for zero, then you will not require glasses for distance vision but you will require glasses for near vision. If both eyes are targeted for reading (-2.00), then you will not need reading glasses, but you will require glasses for distance vision. If one eye is targeted for distance (zero) and the other for reading (-2.00), you then have “Mono-Vision” and may find that you are now totally free of glasses. Not everyone can do monovision, but it works very well for the great majority of patients.

Premium Single Focus Implants / Monofocal

These lenses are the ideal for many CLE / RLE patients. The single-focus lens implants give patients the best possible clarity at one distance, either for far away, intermediate or up close. Glasses will be necessary for some activities.

Alcon AcrySof IQ Lens Implant

The IQ Lens Implant, for patients without astigmatism, gives the best potential for quality vision, typically for distance only. The AcrySof IQ lens is a single-piece yellow acrylic IOL with a patented surface modification that treats spherical aberration and the refractive error. These lenses are more difficult to manufacture, but their optics are better. Plus, while all currently available artificial lenses filter UV light, the AcrySof IQ lens implant filters both UV and blue light, which more closely mimics the abilities of a natural youthful lens.

Premium IOL’s: Alcon AcrySof Toric Lens Implant

The Toric Lens Implant, for CLE / RLE patients with astigmatism, corrects both conditions simultaneously. The lens incorporates an optical design that corrects for pre-existing astigmatism in CLE / RLE patients, resulting in significantly improved distance visual outcomes.

Premium IOL’s: Multifocal IOL’s

Traditional lens implants are monofocal of single-focus lenses, meaning they offer vision at one distance only (far, intermediate, or near). The new multifocal lens implants offer the possibility of seeing well at more than one distance, with less dependence on glasses than the standard mono-focal lens implant. These premium lens implants are available for select patients who meet specific criterion set by the Wellington Eye Clinic ophthalmic surgeons.

Vivity IOL

A new IOL that is so different from other multifocal
IOLs that the category it fits in still needs to be named. For the moment it fits into the EDOF
group of IOLs (Extended Depth of Focus) but it behaves to differently to other EDOF IOLs
that it warrants its own category. For the moment it is being called a “Wavefront-shaping
IOL.” What it means for the implantee is an extended range of vision (far, intermediate like
the computer screen or dashboard of a car and some near tasks) with the same optical
quality as a monofocal IOL. This has not been achieved before with any multifocal IOL – the
fact that the visual quality shows no degradation compared to a monofocal IOL (that would
require glasses for near and intermediate tasks).

Premium IOL’s: Alcon AcrySof ReSTOR Lens Implant

The ReSTOR Lens Implant uses apodized diffractive technology — a design that responds to how wide or small the eye’s pupil might be — to best provide near and distance vision, but objects at intermediate distances may still be somewhat out of focus. No lens can promise you perfect vision or that you will never have to wear glasses ever again. But in FDA studies with this lens, 80% of patients reported that they never wore glasses after the procedure. When patients did need to wear glasses, most often it was for intermediate distance, for example: piano music, computers that sit further away, top shelves at the supermarket. There is a newer ReSTOR IOL recently launched (+2.50 add) and this IOL has greatly improved the intermediate vision (like for seeing a computer screen). This version of the ReSTOR lens is the IOL that we n recommend for patients requiring multifocal lens implants when working on the computer is important to them. Using the +2.50 Add ReSTOR in the dominant eye and the +3.00 Add version in the non-dominant eye can provide patients with a full range of vision without the use of glasses. We have also introduced the Zeiss Trifocal IOL to the lenses that we use and this is also an excellent IOL. We will discuss the IOL choice that best suits your needs.

Trifocal IOL's

These IOLs provide 3 areas of vision namely distance, mid-range or intermediate (dashboard, PC) and near (phone). The clinic implants all types of trifocal IOLs and your surgeon will guide you on the best choice for your needs and lifestyle.

Pinhole IOL / AcuFocus IC-8

These IOLs provide 3 areas of vision namely distance, mid-range or intermediate (dashboard, PC) and near (phone). The IC-8 is implanted into 1 eye only and a monofocal is implanted into the other (dominant) eye. The clinic implants all types of presbyopia-correcting IOLs and your surgeon will guide you on the best choice for your needs and lifestyle.

Dear Arthur,

I hardly know how to begin to thank you for the amazing results of my cataract surgery, an outcome which far exceeded even my most optimistic expectations.

My distant vision seems better than it ever was before and, even more marvellous and an extra bonus I think, is that I can still read quite well without using my glasses. I had thought things would revert to the situation of a few years ago when I really could not read at all without glasses and would have to make sure I carried my reading glasses with me all the time.

Thank you too for all the information you gave me prior to the operation. I really appreciated this. I know I was very nervous on the days of the operations but being so well informed had really calmed me down to some extent. I think without this I would have been really hysterical and could not have gone through with the procedure.

Everybody at the Wellington Eye Clinic was extremely helpful and supportive. Thanks to Ann-Marie, Avril, Cian, the nurses and receptionists. They all contributed to making a visit there, even in such scary circumstances, a pleasant experience.

In the Beacon Hospital everyone I met was also extremely helpful and supportive. The anaesthetist, Dr Silviu Gligor, was brilliant and I had absolutely no after effects from the anaesthetic. The anaesthetic nurse Abie (I hope I have the name right) looked after me so well that I was amazingly almost able to forget that I was waiting for an operation.

I am even hoping that the amazing outcome and the very good overall experience in the Wellington Eye Clinic and in the Beacon Hospital may have worked another miracle. After a bad medical mishap that happened years ago and caused me to avoid any type of medical treatment and sometimes even medical consultations, I think that this experience may have restored my faith in the medical profession.

Yours sincerely

Barbra B.
