What is a cataract?

Cataract is an age-related eye condition derived from the sclerosis (loss of elasticity) and opacification (loss of transparency) of the crystalline lens. As a result light does not reflect correctly on the retina causing a decrease of vision in affected patients.

Symptoms

Cataracts develop progressively and patients might not notice the decrease in vision until the condition is moderately advanced. Most frequent symptoms include:

Loss of far vision. Fading colours and brightness.

Blurry vision (veil vision).

Dysphotopsia (glare). Double vision (monocular diplopia).

Different types of cataracts

Although the most frequent type of cataracts is age-related, depending on the cause and moment of onset cataracts may be classified into the following categories:

1

Senile cataracts

As a direct consequence of the ageing of the crystalline lens. It eventually leads to gradual loss of transparency.
2

Metabolic cataracts

Caused by metabolic disorders that affect the crystalline lens.
3

Congenital cataracts

Cataracts are not frequent in infants, when they occur they may be caused by infections during pregnancy, chromosomopathy and inherited diseases.
4

Traumatic Cataracts

Quick-developing cataracts as a result of trauma that affect the crystalline lens, like impacts, concussions, electric shocks or radiations.
5

Toxic Cataracts

Induced by drug abuse or long-term use of topic or systemic corticosteroids.
6

Secondary Cataracts

Developed as a result of other pathologies (myopia magna, closed angle glaucoma, chronic anterior uveitis, etc.).

CATARACT
CORRECTION

The only effective treatment for the elimination of cataracts is surgery. Optical correction (eyeglasses, contact lenses) and medication do not correct this pathology.

Cataract surgery replaces the opacified crystalline lens with an intraocular lens (IOL).

Cataracts are eliminated using the phacoemulsification procedure with intraocular lens implant. Femtosecond laser (femto phaco) may be used as an adjuvant method. Phacoemulsification technology can be replaced by Nano Laser surgery.

PHACOEMULSIFICATION
SURGERY

Phacoemulsification is a microincisional, sutureless, outpatient procedure for cataract surgery.

In this procedure an ultrasonic probe is inserted in the eye to break up the opaque lens into tiny particles. Emulsified lens matter is later extracted by the surgeon through a minimal incision

Benefits of cataract surgery

Intraocular lenses are made of biocompatible material and are implanted for life. There is no age limit for their implant.

Cataract surgery can correct refractive errors

(myopia, hyperopia and astigmatism).

Surgery can be performed at any moment

it is not necessary to wait for the full development of cataracts.

Simple sutureless surgery with a quick recovery

Cataract surgery is an outpatient procedure.

PSEUDOPHAKIC
INTRAOCULAR LENSES

Cataract surgery replaces the opacified crystalline lens with an intraocular lens. These lenses are innocuous and biocompatible.

However, not all phakic intraocular lenses are the same. Choosing a specific lens will depend on whether the purpose of surgery is just to remove the cataracts. Refractive errors may also be corrected which requires different lenses. Lenses can be monofocal or multifocal in terms of their focusing distance (near, medium or far). Intraocular lenses that correct astigmatism are known as toric lenses.

The posterior capsule of the crystalline lens in which the intraocular lens is implanted becomes fibrous with time and causes a reduction of vision (commonly known as “dirty lenses”) although it is actually the posterior capsule on which the lens is supported that is affected. This situation has a quick simple solution with the use of YAG capsulotomy.

FREQUENTLY
ASKED QUESTIONS

Select any of the following FAQs from our patients and check the answers. If your doubts are not solved please use the contact form below to get in touch with us.

When should I have cataract surgery?

Cataract surgery is performed when vision loss limits daily activities. This vision impairment begins at 0.5 in the eye chart (sometimes less).

At this point activities like reading and driving become difficult.

Can my cataracts improve without surgery?

No. The cataract process is associated with ageing and develops in an irreversible form. Surgery is the only effective treatment.

Can cataract surgery improve myopia/hyperopia?

Yes. The intraocular lens that replaces the eye lens is adjusted to correct the patient’s myopia/hyperopia.

Can cataract surgery correct astigmatism?

Yes. There are several methods to correct astigmatism during cataract surgery. One of them involves making relaxing (arcuate) incisions which reduce astigmatism. Another method is the use of special (toric) lenses. In this case the results are less predictable than in the correction of myopia or hyperopia, but the reduction of astigmatism will still be considerable.

Will my vision recover 100% after cataract surgery?

That will depend on the condition of the eye structures. Initial prognosis is based on a study carried out before surgery.

A 100% healthy eye that loses vision with cataract will recover its vision 100% after surgery, however if the retina is damaged and the vision is reduced to 60%, cataract surgery will only restore vision to 60%.

Which intraocular lens will I have implanted?

The type of intraocular lens to be implanted depends on the needs of patients and their daily activity

  • Monofocal lenses provide good far vision and require the use of small reading glasses
  • Multifocal lenses provide good far and near vision. Eyeglasses are only needed for long reading periods, high precision works or work with computers.
  • Toric lenses correct astigmatism both in their monofocal or multifocal versions.

Are intraocular lenses implanted for life?

Yes. All intraocular lenses manufactured nowadays are made of advanced materials that guarantee lifetime use.
