CATARACTS EXPLAINED

In these toggles we explain what you need to know about cataracts

As we age, the eye’s natural lens becomes cloudy. This is called a cataract.

Cataracts eventually occur in everyone. The majority of cataract surgeries are undertaken for patients in their 60’s and 70’s, but surgery can be performed sooner or later than this.

Cataracts produce changes in the vision which patients perceive as the following common symptoms:

  • Blurred or foggy vision
  • Difficulty seeing the writing on television or the action in a sporting fixture
  • Difficulty reading, or needing brighter lights to read
  • Shadowing or ghosting of the vision
  • Glare or dazzle from lights, such as when driving at night
  • Difficulty recognising people’s faces
  • Double vision, or multiple images, from one eye

There is published research that suggests an adverse effect of cataract on the body’s circadian rhythm, sleep and mood centres. This may contribute to disrupted sleep and altered mood, including depressive-type symptoms in some patients. These studies also provide some evidence that cataract surgery may contribute to improvement in quality of sleep and depressive symptoms in certain patients.

Cataract can cause other symptoms as well as those listed above. A thorough examination will help determine the eye’s overall health as well as the best treatment options for each patient.

A cataract occurs naturally as we get wiser (…or older).

However, it is possible for a cataract to occur earlier than usual as a result of ocular inflammation, diabetes, taking certain medicines, ocular trauma, familial tendency, and sometimes just by chance.

A thorough examination will help determine the eye’s overall health as well as the best treatment options for each patient.

Traditional cataract surgery

With traditional cataract surgery, the natural lens is removed and replaced with a clear plastic lens. Spectacles are then required to see clearly at other distances. This is the treatment you will have with the NHS.

Refractive Cataract Surgery

If you would like to see at all distances without glasses, then Refractive Cataract Surgery is the best option for you.

After cataract surgery, we can replace your natural lens with a monofocal lens implant. This provides good distance vision and a greater ability to read without glasses.

While many patients are candidates for multifocal lens implants, this is not the case for all patients. We will discuss your particular requirements and suitability in detail at your consultation.

Why should I have my cataracts removed privately?

With NHS cataract surgery, you will usually be offered monofocal lenses, which have a single point of focus. This means the lens will be fixed for either near or distance vision, but not both.

At iLase you can have refractive cataract surgery where you choose from a range of lenses that enable the eyes to focus on both near and distant objects.

Why did I develop a cataract?

Usually, a cataract develops naturally with the passage of time. It is possible to develop a cataract earlier or later than average, and they can sometimes be associated with other medical conditions.

Is my cataract ready to be removed?

A cataract does not need to be ‘ripe’ for removal. Cataract surgery can be an appropriate treatment when the symptoms are sufficiently troublesome for you, and when you are willing to consider ways to improve your vision.

Will I have to wear glasses after my cataract is removed?

Not necessarily. This depends on the type of lens implant you choose to receive. With a monofocal lens, you will need glasses for reading.

Multifocal lens implants provide a greater degree of freedom from glasses than monofocal lens implants, including a greater ability to read without glasses.

I’ve always been near-sighted and able to read without glasses. Will this still be the case after my cataract surgery?

Not if you have a monofocal lens implanted to give you distance vision. A monofocal lens cannot focus the vision at different points in front of your eyes so you will need to wear glasses after the surgery.

A multifocal lens, however, can provide distance and near vision without the need for glasses, and so maintains the advantage of near-sight while also providing good distance vision at the same time.

I have astigmatism. Can cataract surgery make this worse?

Yes, that can happen. If your pre-existing astigmatism is not considered in detail before surgery is performed, then it is possible for astigmatism to increase as a result of the operation. This may lead to blurred vision and the need to use glasses all of the time.

However, with a thorough set of pre-operative tests and careful planning, your astigmatism can actually be treated as part of your cataract surgery. This could make a great difference to the result of your surgery and optimise your visual outcome.

Premium lens implants can combine correction of astigmatism with multifocality, providing even greater independence from glasses after surgery.

Is it true that cataract surgery is not worth doing if I have macular degeneration?

No, this is not true. Cataract surgery can allow more light to enter the eye leading to brighter vision and the possibility of improved clarity.

It is not possible to predict how much benefit may be gained after the cataract operation, but the presence of macular degeneration should not prevent you from discussing the possible benefits of cataract surgery with an ophthalmologist.

I’ve had laser vision correction in the past. Does this cause any difficulties when I have my cataract treated, and how can these be addressed?

The surgery is done in the same way as for other patients.

However, the preoperative calculations to select the correct strength of the lens implant are less accurate in eye that have undergone prior vision correction surgery such as LASIK, PRK, SMILE and others.

This means that patients are significantly more likely to have a spectacle prescription after surgery and need to use glasses most or all of the time.

Prof Muhtaseb uses the most up-to-date technology to measure the eyes and gather data preoperatively.

He then utilises the most effective lens calculation methods, based on the latest published evidence, to calculate the strength of lens required for each eye.

Prof Muhtaseb continuously monitors the outcomes of these cases and has presented the results of his surgeries for such patients at international meetings.

If you have previously undergone a vision correction procedure, it is essential that you discuss the method of lens calculation with your surgeon.

I’ve had laser vision correction in the past. Can I still have a multifocal IOL when my cataract is removed?

Yes, it is still possible to use a multifocal IOL if you’ve had prior vision correction surgery. The caveat is that the eye examination must be entirely normal with no abnormal features of the cornea or other parts of the eye.

Prof Muhtaseb will discuss your options in detail with you at the consultation.

Astigmatism: A Tale of Two Patients

Patient 1 received cataract surgery with another surgeon at a different clinic. They had 1.75 dioptres of astigmatism before cataract surgery but left with 4 dioptres after cataract surgery. The patient was left with poor vision unless they wore glasses with a strong astigmatic prescription at all times.

The patient came to iLase for help. Prof Muhtaseb informed the patient of the benefits and risks of the various surgical means that could help to correct residual astigmatism.

Patient 2 consulted Prof Muhtaseb about cataracts. They had 1 dioptre of astigmatism in their glasses. Prof Muhtaseb determined the likely outcome with and without a toric lens implant using the latest technology for measuring the eye and calculating the best lens implant.

Prof Muhtaseb took into account the amount and direction of the patient’s astigmatism and the effect of surgery on the corneal shape. With these measurements, Prof Muhtaseb was able to recommend a toric lens implant with 2.75 dioptres of toric astigmatic correction.

The patient’s postoperative result was excellent. They had zero astigmatism in each eye and sharply focused distance vision.

These cases illustrate the importance of accounting for the magnitude and direction of astigmatism before surgery. Measuring the eye with very accurate devices, understanding the effect of surgery on the eye, using the most accurate formula to model the postoperative outcome, and tailoring the lens implant choice to each individual eye is essential.

Every eye is different, and each patient should expect a tailored surgical plan for each eye – this is Prof Muhtaseb’s standard of care.
