    What is cataract surgery?

    At ICR we are aware of the loss of quality of life suffered by patients with cataracts, as well as how incapacitating it can be for them to depend on glasses to carry out their daily activities. For this reason, we work with enthusiasm, involvement and commitment to ensure that our patients recover their vision and that they do so depending as little as possible on their glasses.

    Cataract surgery is one of the most common operations in ICR. We perform it using a procedure called phacoemulsification, which uses ultrasonic energy to remove the opacified lens (cataract) and replace it with an intraocular lens. Thanks to current technology, today we can customize this intraocular lens to correct refractive defects of the eye in the same operation: myopia, hyperopia, presbyopia and astigmatism.

    It is an outpatient surgery (does not require hospital admission), which requires a microincision of just 2 mm and for which we use topical anesthesia (drops) together with light sedation. Once the operation is finished, the patient can go home on his own foot.

    Thanks to the latest advances in intraocular lenses we can eliminate the cataract and reduce the dependence on glasses at the same time.

    Why is lens implantation necessary in cataract surgery?

    Trifocal lenses are the lenses of choice for patients who decide to enjoy independence from the glasses after the operation, thanks to the excellent visual results they provide at all distances. At ICR we use state-of-the-art trifocal lenses, which have a focus for distant, intermediate and near vision and, in their toric version, also allow the correction of astigmatism. The objective is that after surgery the residual graduation of the eye is as low as possible and the patient can enjoy the desired independence of the glasses.

    In cases where, due to the characteristics of the eye, trifocal lenses are not the best option, there are alternatives such as the so-called extended focus lenses (also known as EDOF), that allow these patients to achieve not only good visual acuity from a distance but a very good functional vision at intermediate distance. At ICR we are pioneers in the use of this type of intraocular lens and we have implanted them with very good results.

    Our ophthalmologists specialising in cataracts will advise each patient the best option based on their needs, lifestyle and eye medical history.


    At ICR we have the most advanced surgical microscopes, which allow us to implant monofocal and premium intraocular lenses (trifocal and toric) with maximum precision.

    Cataract Suite Markerless: Callisto

    ICR was one of the first centers in Spain to have the Cataract Suite Markerless system, the most advanced microscopy system in cataract surgery. This innovative device allows the information collected by the different teams involved in the operation to be automatically combined. It is currently the safest, most accurate and most comfortable technology.

    With this system the risks are reduced, since the transmission of data and marking is carried out automatically. The system marks the exact place where the lens must be inserted in an automated and assisted way, so that surgeons can focus all their attention on the procedure. The progress achieved with this technique has been enormous and it is already considered the next-generation cataract surgery.

    Centurión Equipment

    ALCON’s Centurion phacoemulsifier improves the safety and effectiveness of cataract surgery by automatically increasing the stability of the anterior chamber of the eye. Thanks to a new active fluid management system, the surgeon can better control intraocular pressure throughout the procedure and thus be able to develop microincision techniques of less than 2 mm in an efficient and safe way, both in coaxial and biaxial techniques.

    Stellaris Equipment

    It is a highly reliable phacoemulsifier that provides an extraordinary level of performance, efficiency and results. It provides surgeons with advanced technology for the proper performance of cataract surgery.

    IOLMaster 700

    At ICR we also have the IOLMaster 700, the first device for optical cataract biometry, which allows us to obtain optimal refractive results by providing us with the highest precision in calculating the power of the lens that we are going to implant in the eye. It is an OCT image-based biometry that allows visually to verify measurements and detect unusual geometries in the eye, such as an inclination or an offset of the lens.

    Frequently Asked Questions

    Does cataract surgery cure nearsightedness, farsightedness, astigmatism and presbyopia?

    The intraocular lens used to replace the opaque lens allows correction of the patient’s refractive problems, such as nearsightedness, farsightedness, astigmatism or presbyopia. In this way, and depending on the type of intraocular lens chosen, the patient can reduce or even eliminate his dependence on glasses.

    What are the symptoms of cataracts?

    Most age-related cataracts develop gradually, so obvious symptoms may not be apparent at first. As the cataract progresses, it can cause more noticeable symptoms, such as blurred or double vision, dim or yellowish vision, difficulty seeing at night, or sensitivity to light.

    How is the diagnosis made?

    In order to diagnose a cataract, the patient must go to a specialist, who will ask about their medical history (medicines, systemic diseases, trauma, eye diseases …) and will perform a complete eye study, which will include tests such as a pupillary and refractive examination, a biomicroscopy, a tonometry and a study of the fundus among others.

    How long does a cataract surgery take?

    The cataract operation usually takes approximately 20 minutes. This is an outpatient intervention (does not require hospital admission), for which topical anesthesia (drops) is used.

    What is the postoperative period like? How long does it take to resume normal life?

    The postoperative period of a cataract surgery is usually painless and causes little discomfort, which disappears after a few days. Some of the discomforts that can be experienced are dry or gritty eyes, glare, etc.

    After the intervention, the patients can go back to their normal life, taking some precautions during the first week, like avoiding physical effort or sudden movements, not rubbing their eyes, sleeping on their back or on the side of the eye that has not been operated, wearing sunglasses to go out and taking care of hygiene measures, in addition to following the treatment and controls indicated by their ophthalmologist.

    Can a child have cataracts?

    Many people believe that cataracts only affect older people. However, there are also cases of cataracts in children. These cataracts can be congenital (they are present at birth) or acquired (they appear later).

    Because children’s vision is in the developmental process until age 8 or 10, untreated pediatric cataracts can lead to long-term vision problems. For this reason, early detection and treatment can prevent permanent vision loss.

    The treatment for childhood cataracts may vary depending on its type and severity. In some cases, they require surgical intervention in order to be removed. In others, surgery is just the first step to complete eye rehabilitation, and treatment must continue with the aim of repairing the connections between the brain and the eye and for the latter to learn to focus correctly.

    Only older people have cataracts?

    The majority of cataract cases appear from the age of 50 or 60 when, due to age, the tissue that forms the lens of the eyes loses flexibility, transparency and thickness. However, beyond age, there are other eye pathologies, previous eye surgeries or diseases such as diabetes that can also cause the creation of cataracts.

    When should you undergo cataract surgery?

    Contrary to what was previously believed, it is currently recommended to perform the operation when the cataracts begin to affect the patient’s vision. In this way we avoid long waits, loss in the quality of life of the patient and complicated interventions and postoperative.

    Patients who have immature or incipient cataracts and do not require surgery should go for an annual or even more regular review if there is a symptomatic decrease in vision. Ultimately, the only way to remove cataracts and restore lost vision is surgery.

    Can both eyes be operated at the same time? How much time should be left between the operation of one eye and the other?

    Although the percentage of serious complications derived from a cataract operation is low, if they occur in both eyes after bilateral surgery, they can significantly disable the patient. Thus, good judgement suggests that is better to wait a few days (one or two weeks) between surgery on one eye and the other.

    What is a secondary cataract?

    Secondary cataract is an opacification of the posterior lens capsule that can appear a few months or years after undergoing a cataract extraction operation. Up to 20 % of patients who have undergone cataract extraction may experience them.

    It is not possible to know if a patient will develop a secondary cataract after a cataract extraction, but it is usually developed mainly by younger patients who have undergone cataract surgery.

    The treatment that is usually recommended after the appearance of a secondary cataract is a capsulotomy, which consists of making an incision in the posterior capsule with the help of YAG Laser.

    Is it possible to undergo a cataract operation if you have previously had laser refractive surgery?

    Yes, in fact, we do it regularly. In these cases, it is just important to know that the patient has undergone refractive surgery, so that the ophthalmologist can request the appropriate tests to assess the shape of the cornea. Next, and by means of a series of specific formulas, the power of the lens to be placed inside the eye during cataract surgery will be determined. In no case, therefore, does refractive surgery represent any problem or pose any added difficulty when performing cataract surgery.
