Personalised cataract surgery without waiting lists.

Recover your best eyesight

Cataracts, the most frequently operated disease


In the Miranza clinics alone, we perform over 17,000 cataract surgeries each year, carried out by a team of specialist ophthalmologists.


We also have extensive experience in handling congenital cataracts and complex cataracts related to other diseases, whether ocular (high myopia, uveitis, trauma, etc.) or general (diabetes, hypothyroidism, etc.).

Being able to get rid of this curtain
with a cataract operation has been like a breath of fresh air”.

“My eye problem made me feel old.
I now feel 20 yearsyounger. I can see
perfectly without glasses, both need and far”.

How do I know if I have a cataract?

A check-up with the ophthalmologist will confirm precisely the type and degree of evolution of your cataract. However, these are some of the warning signs that might encourage you to visit the specialist.

I have blurred vision, as if were looking through a fogged-up window.

Color look dull, with little contrasr and intensity.

Ligth bothers me and I’m eassily dazzled.

I find it more difficult to see properly at night.

I have to change the prescriptionof my glasses very often.

When is it time to have the operation?

That is a decision that our ophthalmologists in the Miranza clinics agree upon individually for each patient. But one thing is clear: the old idea of having to wait until the cataract is “mature” or “well formed” before operating on it no longer applies, thanks to the technological development of this surgery and the great effectiveness and safety it offers.

When considering the surgery, as well as weighing up your personal and professional needs, we perform a complete pre-operative study, providing all the diagnostics tests necessary for obtaining in-depth information on the characteristics of your eye.


The most usual tests are:

Biometrics: to ascertain the precise measurements of your eye and calculate the power of the intraocular lens implanted during surgery.

Topography: to analyse characteristics of the cornea, such as its shape and curvature, which have an impact on the calculation of the intraocular lens.

Endothelial count: to study the corneal cells and ensure the tissue is in good condition for the operation.

Optical coherence tomography: to detect any intraocular problem that may jeopardise the final visual result.

Benefits of early surgery

Nowadays, early cataract surgery with a flexible, personalised medical recommendation allows for:

Minimally invasive surgery, which reduces the risk of any complications and makes recovery easier. You will generally be able to see well and recover your everyday activities after 24h.

Improved quality of life, as it is a rehabilitation surgery. Stopping the cataract from reaching advanced stages prevents it from significantly limiting your everyday activities. For example, according to studies, the risk of hip fracture after this operation drops by 16% and of having a traffic accident by 13%. Furthermore, cataract surgery also leads to a reduction in the use of glasses, which is an important factor associated with quality of
life for many people.

Cataract surgery in three steps

Step 01

We access the lens through a microincision of barely 2 mm, which will require no stitches to close.

Step 02

We dissolve and aspirate the cataract using ultrasounds. This is known as phacoemulsification.
We remove all the remains of the opaque lens and leave only the fine membrane around it, the posterior capsule.

Step 03

This capsule is used to support the intraocular lens we implant to replace the crystalline lens.
The lens is made of flexible and biocompatible materials that will remain stable in your eye without the need for future replacement if everything goes according to plan.

Enjoying once again a life to be seen

The aim of cataract surgery is to ensure you can enjoy your best eyesight once again and do so without havingto depend on your glasses. By implanting an intraocular lens, we correct any prior refractive errors you might have, whether it is myopia, hyperopia, astigmatism or presbyopia (“eyestrain”).

When choosing the lens, which is adapted to the characteristics of your eye, we also consider your specific visual needs and your lifestyle.

Do you drive? Do you like to read? Do you paint with your grandchildren? Do you spend a lot of time outdoors?

Depending on your answers, we will recommend one solution or another to ensure the most satisfactory results. Cataract surgery in Miranza is not standard but personalised, providing the best diagnostic equipment and the new Premium lens models, as well as expert advice.

Are you familiar with the different types of intraocular lenses?

Premium intraocular lenses offer good vision quality at different distances without glasses:

  • Monofocal lenses: these focus only one specific range of vision (normally distance).
  • Toric monofocal lenses: as well as correcting distance vision, they also correct astigmatism.
  • Extended depth of focus lenses (Enhanced Monofocal Lenses): these correct distance vision and improve intermediate vision.
  • Extended range depth lenses with or without astigmatism correction: these extend distance, intermediate and sometimes even near vision.
  • Multifocal lenses (bifocal, trifocal) with or without astigmatism correction: these allow you to see at all distances: near, intermediate and far.
