CATARACT

Cataract is a disease treated only with surgery that involves the removal of the blurred crystalline lens and its replacement by an artificial lens (intraocular lens).

The method used, apart from a few exceptions, is called phacoemulsification. This is a minimally traumatic to the eye technique, where the blurred crystalline lens is shattered through a small incision (2-3mm) using ultrasound, and is aspirated. Through this incision, the IOL is also inserted.

 

The major advantages of phacoemulsification include the absence of sutures and a short recovery time. For the surgery a preoperative check and the correct measurement of the refractive power (biometrics) is required, of which the IOL type to be used on the patient will depend.

 

The technique of phacoemulsification constantly evolves, in order to improve equipment and intraocular lenses offered, so that we now have a perfect postoperative result. The development of intraocular lenses allows us to fix all preexisting refractive errors (myopia, hyperopia, astigmatism) and farsightedness.

To be able to have the perfect refractive outcome, minimizing all possible intraoperative complications, cataract surgeons have one more “weapon” at their disposal, the Femtosecond Laser.

The Femtosecond Laser allows the surgeon to perform with absolute precision specific steps during the procedure, without the risk of complications.

The process starts with the detailed illustration of the anterior segment of the eye, using optical tomography. Then, the positions and dimensions of the points where the surgeon will intervene using the laser are carefully selected.

Specifically:

  1. The incisions in the cornea, that lead to their rapid occlusion postoperative, and the simultaneous correction of astigmatism.
  2. Capsulorhexis (ie. the opening of the lens bag, from where the blurred lens will be aspirated, a very important step during procedure, which is ideally in the center and each time has a perfect circular shape, that can hardly be achieved even by the hand of a very experienced surgeon.
  3. Slicing of the blurred lens, so that the lens pieces are aspirated with a lot less power and in less usage time.

The Ophthalmological Institute ‘Diathlasis’ is the only one in Northern Greece to own and operate the latest equipment for cataract surgical removal, such as:

  • LenSx Femtosecond Laser (ALCON)
  • Centurion (NEW phacoemulsification machine by ALCON)
  • Lumera 700 (NEW microscope by ZEISS)
  • Callisto (Computer assisted cataract surgery - ZEISS)

 

Duration of cataract surgery is about ten to twenty minutes, and anesthesia is usually applied by the instillation of anesthetic drops.

After surgery, the patient is not hospitalized, but returns home and can begin the process of using the necessary eye drops postoperatively, for three weeks.
