In the realm of ophthalmic surgery, the laser is king, and his success is due simply to the eye is transparent, the laser can easily penetrate and act at all levels, of the cornea to the retina
“Ophthalmologists are the biggest users of laser, confirms Dr. Catherine Albou-Ganem, of the hospital of Quinze-Vingts, Paris. There are many types, delivering radiation in the wavelength range allow for a multitude of uses: burn, cut, coagulate, vaporize, heal.
.. .. Its applications are endless” This surgery began in the 1980s, with gas lasers argon, which are used even today to treat patients with diseases of the retina. This type of laser, by its anticoagulant effect and healing, allows, for example, to prevent the extension of a tear, retinal, or “seal” of the vessels that leak. This photocoagulation is also often used to control macular degeneration related to age (AMD).
“But the major development of the laser rest refractive surgery, says Dr. . Albou-Ganem. This technique is to change the shape of the cornea by ablation.
Its ability refractive is then modified and, as a result, the path of light rays in the eye corrected. Thus, we can correct a defect in vision so that the rays converge, of course, the retina. This surgery is not limited to myopia, she insists, hyperopia, astigmatism and even presbyopia are treated with excellent results. “A high cost not reimbursed by the Security socialeDe fact, this surgery has gained in precision and comfort over time, particularly with the techniques of Lasik (Laser-Assisted In-Situ Keratomileusis) and Relex Smile. And yet, in France, this surgery is still limited.
Each year, in our country, 200,000 people are making the choice of an operation laser: it is low compared to 30 % of myopes in the Hexagon, 15 % from astigmatism, the 10% of the hyperopic and millions of presbyopic always more numerous with the aging of the population. Why is this restricted? The cost first: between 3000 and 3500 € the transaction, not reimbursed by the social Security and rarely supported by the complementary health. The fear of complications afterwards.
Alerted by an association of patients dissatisfied, the commission for the prevention of risks to the national security Agency of the drug (MSNA) has just published a document stating that these hazards affect 20% of the operations at the Lasik.
But, to tell the truth, this document primarily refers to trivial incidents, such as dry eye, transient.
. Dr. . Albou-Ganem admits, however, that “complications are more severe, of an infectious nature or inflammatory, may occur exceptionally, but as in any surgical procedure, she says. Refractive surgery is predictable and safe. And the laser is a great tool that never ceases to open up new therapeutic prospects.
In the years to come, it is the generalization of its use in the treatment of cataract, which is expected to grow to facilitate the destruction and replacement of the crystalline defective. .” .
