Micro-incision Cataract Surgery (MICS)

The primary purpose of cataract surgery is to improve eyesight by replacing the natural crystalline which has become opaque with an intraocular lens. The most advanced, pioneering surgery for treating cataracts is Micro-incision Cataract Surgery (MICS). 

Cataracts form when the crystalline lens, normally transparent and whose function is to focus images on the retina, becomes cloudy.  Cataracts commonly appear with age, although there are other causes such as eye inflammation, injury or metabolic changes.

 The main symptoms of cataracts are: 

  • Frequent changes in spectacle prescriptions.
  • Blurred vision, which gets worse over time.
  • Sensitivity to light and glare.
  • Fading or yellowing of colours or objects.

Benefits of the operation

The operation is performed very quickly in the operating theatre, is painless and does not require hospitalisation. There is no need to stop taking your regular medication before the operation (for example, any anticoagulant drugs) and there is no need for any injected anaesthesia or sutures. Neither is it necessary to cover the eye after the surgery. 

You will not have more than three post-operative checkups. This surgery corrects patients' previous refractive errors, such as myopia (short sightedness), hypermetropia (long sightedness) and astigmatism.

Medical-technical description

Cataract surgery is performed using a surgical technique called Micro-incision Cataract Surgery (MICS), which has been developed by the specialists at VISSUM, making it possible to remove the cataract through an incision measuring no more than 1.5 mm thick and allowing the patient to see again immediately after the operation. 

This technique considerably reduces risks and has encouraged the appearance of a new generation of intraocular lenses that can be inserted into the eye through an 1.5 millimetre incision.

About the operation

The operation takes about 20 minutes and is performed under local or topical (eye drops) anaesthesia. A tiny incision is made in the cornea through which the cataract is removed and replaced by an intraocular lens that also corrects any existing sight problems, such as short and long-sightedness.

Before the operation

  • Patients must refrain from wearing contact lenses for at least 7 days before the ophthalmological examination.
  • A blood test and pre-anaesthesia study will be performed by a specialist.
  • If you are taking any medication or you suffer from any illnesses, you must tell the ophthalmologist.
  • You will be given some special towelettes with which you must clean your eyelids for four days before the surgery.
  • You will use some eye drops three times a day on the day before the surgery.

Post-operative care

  • You will continue to use the eye drops given to you by your doctor until you visit the ophthalmologist again between 24 and 48 hours after the surgery.
  • It is important you do not touch the eye on the first day and you must refrain from doing anything strenuous for five days and try not to rub your eyes.
  • After 48 hours you can go back to your normal activities so long as you take the precautions advised by our professionals.
