VISIAN ICL LENS IMPLANT
The human eye can have refractive defects which cause blurred vision and these are myopia, hyperopia and astigmatism.
In a normal eye (emmetrope), images enter the eye and are focused by the cornea and the crystalline lens on the retina, which acts like the film in a photographic camera and which transmits the images to the brain. If these images are not projected onto the retina, blurred vision occurs and this is what happens when the eye has a refraction defect. For patients to be able to see clearly, it is necessary to focus the images on the retina and this can be achieved by wearing glasses, contact lenses or by having REFRACTIVE SURGERY
Myopia : In a myopic eye, images are formed in front of the retina, causing blurred far vision.
Hyperopia : In a hyperopic eye, images are formed behind the retina, causing blurred near vision and, over time, far vision too.
Astigmatism : In an astigmatic eye, the images, whether they be far or near, are out of focus, causing distorted vision.
When the myopia or hyperopia is very elevated and/or the cornea which we wish to remodel is too fine, the technique which we recommend for the correction of your refraction defect is the implantation of an intraocular lens, which can also simultaneously correct the astigmatism.
The Visian ICL, is an intraocular lens which is put into the eye through a small incision in the cornea, implanting it between the iris and the crystalline lens, which is to say, in the posterior chamber of the eye. In some cases it is necessary to perform a laser iridotomy on the iris before implanting the ICL, to facilitate the diffusion of aqueous humor from the posterior chamber to the anterior chamber of the eye.
This technique is carried out under local anesthetic, without the patient being hospitalized and visual recuperation is rapid. Within 24 hours, the patient can cope without the need to wear glasses.
