Written by:From time immemorial the cataract surgery is one of the most practiced (since the times of the ancient Egyptians). It is an operation that was being performed when the patient was losing sight. Faced with this problem, until recently, he proceeded to the removal of the lens, or the point where it forms a cataract, and for this reason the operated patients had to carry the prescription glasses (14 or 15 diopters). The characteristics of the intraocular lenses are explained in this article by our expert in Ophthalmology
Consequently, over the years is a technique to be able to replace the crystalline lens with a particular type of lens is studied. Since the '80s, therefore, they are produced intraocular lenses perfectly tolerated by the eye. The types of intraocular lenses have evolved significantly and, in recent years, not only are used to replace the crystalline lens affected by cataract but also to correct defects such as myopia, astigmatism and hyperopia. In addition, there are multifocal lenses that can replace the glasses for near and far.
Which diseases can be corrected through the implant of intraocular lenses?
Thanks to the system of intraocular lenses there are many diseases that can be corrected. As mentioned before, even astigmatism can be treated using the latest production 'toric lenses called lens' which correct the disorder in an excellent manner. Currently with these new biometrics that are realized by means of a laser you get a perfect lens for the patient can also correct the myopia and hyperopia. In all this we must consider that some myopic patients, prefer to keep a small percentage of myopia since their close up view good; This is a factor to consider in the patient's medical record because each lens has to adapt to the needs of the subject (profession, hobby or exercises done following implantation of the lens).
What are the advantages of intraocular lenses to the patient?
The main advantage offered by the intraocular lenses is the elimination of large lenses for glasses that were used when the intraocular lenses were not yet commercially. The benefits also arise from the surgical technique used for the removal of cataracts which provides only for topical anesthesia (with drops) and which lasts between 15 and 20 minutes; Furthermore, there are no stitches and can be achieved outpatient. Once finished, the patient can go home with the eye without bandages, returning to perform normal daily activities (with the exception of violent physical exertion).
