Femtosecond laser multiplies the accuracy and safety of surgery of cataracts.
study Spanish on the effectiveness of the laser femtosecond.
– for 40 years was not produced a breakthrough in cataract surgery
-the entire population ends suffering falls with age. Eye strain is the first symptom
Madrid, December of 2011- laser femtosecond, whose employment falls has started this week in Madrid, multiplies the accuracy and security of traditional ultrasonic surgery, to automate the surgery and do less dependence on the expertise of the surgeon, according to Dr. José Manuel BenÃtez of the Castle, Professor of ophthalmology at the Complutense University. Dr. BenÃtez Castle directs, in collaboration with the Fundación RementerÃa, a Spanish with this type of laser research project. Last November, the Current Opinion of Oftalmology magazine published a study which shows that cataract surgeons are adopting the technology of femtosecond ” to carry out all processes of the intervention, as performs these surgical steps with greater precision and reproducibility ”.
Femtosecond scanning laser lens on its surface and in its interior, through infrared waves, and millionth of a second, creates a bubble of air that separates the molecules of the lens without cutting or burning any tissue. Thus, it does not damage any adjacent cell. According to Dr. BenÃtez of the Castle, is the first significant advance in cataract surgery since 1967, they appeared the phacoemulsification ultrasonic, and, according to studies, it is very likely to help improve faster as cataract surgeryeffective and safe ”.
All the steps are manuals in the manual technique with ultrasonic: corneal, cut incisions circular capsule that surrounds the waterfall, fragmentation of the lens to its extraction and the introduction of a lens, so results may vary ”, explains Dr. Laureano Ãlvarez-RementerÃaShe has done with femtosecond laser cataract operations in Madrid. However, with this laser, much of the intervention is guided automatically and accurately by the computer in real time ”. It is reduced, thus the possibility that the lens is centered completely, as many people intercepted with the conventional technique, causing haloes or spots on the vision ”, confesses. Various studies to two to three years by the pioneer of this technique, Dr. Zoltan Nagy, of the Semmelweis University, Budapest, have shown that the focus of the lens is much more accurate with femtosecond laser and patients experience a remarkable improvement in visual acuity ”.
Another advantage of intervention with the new laser, according to Dr. Ãlvarez-RementerÃa, is that it is painless, of short duration (about 15-20 minutes) and much faster recovery than with the previous procedure: the patient goes home seeing blurry, visual recovery is not in days but in hours ”.
With this procedure it can also contribute, in one intervention, to solve or improve the troubleshooting Visual such as presbyopia, myopia and astigmatism, adds, and the patient does not have to return to using glasses, nearly nowhere.
Leading cause of blindness in the world
Cataract is the leading cause of blindness in the world. Affects half of those over 65 years but it’s a natural process, progressive opacity of the lens, which begins to manifest itself after 45-50 years, with the eye strain (presbyopia), and that just suffering around the world if live far enough ”, says Dr. Ãlvarez-RementerÃa. It is a common cause of costing well define the image of night and that glasses or contact lenses stop being useful.
The reasons for the opacity of the lens is not known exactly but it is known that sunlight, diabetes and smoking are factors that accelerate the process.
The only way to remove the cataract is drawn opaque lens and replacing it with an intraocular lens.
