Considering cataract surgery

Cataracts are one of the leading causes of visual impairment in the world and are considered a public health issue; they generally occur in people over 60 years of age.

In the early stage of a cataract, you might not experience problematic visual impairment. As the lens becomes more clouded, you can expect significant deterioration of vision that can lead to blindness.

The only effective treatment for cataracts is surgery. Fortunately, it is safe, minimally invasive and represent an opportunity to recover your vision. Discover how.

When to consider cataract surgery

3 minutes
Cataract is a loss of transparency of the natural lens. This reduction in transparency is often progressive, the visual discomfort is most of the time felt when the opacification of the lens is at significant stage. Cataract modifies the colored sensation in a very progressive way, so patient realize after surgery how much they had lost in quality of vision before. After surgery, colors are suddenly more saturated, the blues more vivid, and so on.

With cataract, your day-to-day life will become more complicated.

Cataract patients experience increasing discomfort that initially manifests in everyday life situations that require good vision, driving at night, reading small print, sewing, etc. The decline in visual acuity makes it difficult to read road signs, text banners on television, subtitles in cinemas, etc. Performing sports like golf, tennis becomes difficult and performance drops. Stopping driving at night is often necessary from a certain stage of cataract. Gradually, the discomfort increases to become permanent. The more advanced the cataract, the more of your activities could be reduced.

You should consider surgical intervention as soon you start to feel the first symptoms.

Do not delay cataract surgery if your visual impairment is significant. The cataract evolves gradually towards the complete opacification of the lens and at the very advanced stages of cataract. Your vision could then be reduced to the simple perception of light.

You will need cataract surgery when your visual quality decreases and discomfort your daily activities such as driving or reading. It is important to consider cataract surgery whenever you experience blurry vision even with glasses.

Blindness caused by cataract can be reversible thanks to surgery. Surgery restores the transparency by replacing the natural lens by an artificial intraocular lens. It is therefore never too late to have an operation, but operations carried out at very advanced stages are longer and more difficult.

Operating on a very hard and opacified lens increases the risk of certain intraoperative complications and can affect certain other ocular tissues such as the cornea.

A few things can help while waiting for your surgery!

While waiting for surgery, equip yourself with corrective glasses. In parallel, use vision aid systems like good lighting, or magnifying glasses.


Why considering cataract surgery?

3 minutes
Cataract surgery is the most common procedure performed in the world – all surgical specialties combined – and enjoys a complete success rate in 95% of cases1. The surgical procedure is usually performed under local anesthesia. It is brief and painless. Surgery is the only cure to heal cataract. Cataract surgery restores the transparency of the eye by replacing the damaged natural lens by an artificial intraocular lens.

Cataract surgery will help you recover your quality of life.

Surgery restores ocular transparency and cataract-related symptoms such as glares and impression of visual fog disappear. Colors become more vivid and saturated. Bright lights are sharper and there is no longer a "dirty" feeling of vision. The luminous halos around lights at night disappear or are considerably reduced. It becomes possible again to read small print up close, street names and subtitles from afar.

Improved vision helps regain confidence in driving, especially at night, as well as practicing sports or leisure activities that require good vision. It is easier to travel when you can easily read electronic signs and directions in train stations and airports, and your book or tablet during transport.

The technological progresses made in the intraocular lenses design and manufacturing now makes possible to correct many visual impairments such as myopia, hyperopia, presbyopia, and astigmatism. Thanks to these new technologies, you could even reduce the burden of your glasses at all distances. It could be possible to reduce or even eliminate your need for glasses or contact lenses according to your wishes and expectations.

Cataract surgery is among the safest procedures worldwide.

The use of microsurgery techniques makes this surgery a minimally invasive act. The intervention is performed through a small incision (about 2.2mm) that does not need to be sutured because its small size gives it self-sealing. This results in rapid visual recovery and the absence of pain, as well as the possibility of resuming a normal life very quickly, generally after two or three days.

Most patients would recommend the operation.

The satisfaction rate after cataract surgery is very high, because the procedure is performed in less than 15 minutes under local anesthesia. This anesthesia is most often reduced to the instillation of anesthetic eye drops, but it can be supplemented by a local injection and the taking of sedatives in certain cases.


Methods & Procedures

The objective of cataract surgery is to extract the cloudy lens through a small incision and replace it with a transparent intraocular lens. The choice of an appropriate optical power for this lens makes it possible to correct the eye for certain optical defects.

The surgery is quick and painless.

Before surgery, the surgeon will disinfect the eye to be operated on and administer a local anesthetic. The surgery takes between 10 and 15 minutes. Once completed, the eye will be covered with a protective cover. After a short rest, you can return home. Since you cannot drive afterwards, someone must accompany you on the day of surgery.

The day after the procedure, the operated eye will be checked. Your ophthalmologist will explain the post-operative medical treatment to you.

Mostly, only local anesthesia is needed.

Usually, a local (topical) anesthetic, consisting of eye drops, is used. In some cases, it can be combined with a mild sedative. Another option is general anesthesia (recommended for children, nervous people, or people with specific pathologies).

Your natural lens will be removed and replaced.

A micro incision is performed into your eye. The lens is then removed with a technique of phaco emulsification. The natural lens is fragmented then extracted through the micro incision.

The purpose of the surgery is to replace the lens that has become opaque (cataract) or a clear lens (simple presbyopia) with a transparent artificial implant in the following manner:

    Keeping the eye open by immobilizing the eyelids.
    Making incisions to introduce the instruments into the eye. With modern micro-incision techniques (between 2.0 and 2.8 mm), the wound is self-sealing.
    Injecting a viscoelastic substance, a gelatinous material that helps protect the eye.
    Performing a capsulorhexis: making a round opening in the anterior lens capsule with a special instrument to introduce a probe, which will pulverize the lens core. The opening is made manually or with a laser.
    Lens fragmentation by ultrasound and its extraction (phacoemulsification).
    Inserting the intraocular implant in the capsular bag.
    Removing the viscoelastic substance

Selecting a surgeon

1 minutes
Today there is a vast choice of intraocular lenses, but not all of them induce the same correction, or performance. Some surgeons have developed expertise in optical correction in cataract surgery. These are generally surgeons who practice refractive surgery in the broad sense, which includes laser surgery and corrective surgery using implants.

Choose your surgeon according to your expectations.

Your choice of lens will depend on your expectations. Adequate care is not only based on technical expertise but on understanding your expectations in terms of postoperative optical correction. Your practitioner will have to find the best match between your wishes and what can be corrected in your case, through the selection of the most suitable intraocular lens.
