Refractive surgery: what are the new advances for your eyes?

From diagnosis to treatment: dazzling progress

The experts are unanimous: everything is accelerating today in the field of ophthalmology. From there to speak of revolution? In part! If in the majority of cases, real revolutions only occur every twenty or thirty years, the rest of the time, progress is akin to a continual improvement of what already exists. Machines are equipped with new functions, tools are miniaturized and treatments are personalized. Thus in the 1960s, cataract surgery experienced a revolution, while the 1980s saw the appearance of laser eye surgery, PKR. A real technological revolution, this technique made it possible to treat myopia and hyperopia. Laser eye surgery was then perfected and the Lasik technique was born, making it possible to correct presbyopia and astigmatism.

Ever safer innovations

Nowadays, the surgical techniques have remained the same but the machines are improving and make it possible to assist these surgeries to increase their precision. The best machines are equipped with an eyetracker system, thus making it possible to detect even the micro-movements of the eye during the operation. These innovations offer real benefits not only to the surgeon by allowing him to work more safely thanks to better stability, but also to the patient by allowing him to recover better after his operation. Because with the aging of the population, sight problems have become a real public health issue. If there are different refractive surgery techniques, the first thing to do is to make sure that your eye is operable. After several examinations, the surgeon therefore chooses the most suitable technique. One of the most revolutionary is the SMILE technique.

The SMILE technique: latest innovation in refractive surgery

This new generation of SMILE laser (Small Incision Lens Extraction) has been around since 2010. It can correct a vision defect without opening the cornea (logic of the LASIK technique), or removing the surface layer of the cornea (logic of the PKR technique ). It is only a fragment of the cornea which is cut with a laser and then removed manually by the surgeon through a micro incision. The treatment is performed entirely by the femtosecond laser in just a few seconds. The SMILE technique can correct myopia up to -12D and astigmatism up to 6D. The patient benefits from a less traumatic surgery with better healing, little dry eye and shorter visual recovery allowing a rapid resumption of activities, generally the next day. The operation itself is completely painless.

Today, thanks to powerful computer programs which make it possible to conduct the light beam of the lasers, it is therefore possible to operate on certain myopias considered before 2010 as incurable. “Provided that the sight has been stable for at least two years and that the cornea is neither too thin nor too fragile”specifies Belkacem Asli, head of the Elsan Vision laser center in Toulon. The latter brings together expert ophthalmic surgeons, as well as all the latest generation technologies in refractive surgery, such as the Femtosecond VisuMax laser from Zeiss, the most precise in France. Moreover, this technology is only present in a limited number of refractive surgery centers. Make an appointment for test your eligibility before refractive surgery seems to be a response to the expectations of many spectacle and contact lens wearers. Before, within a few years, the next revolution in refractive surgery. As evidence, Artificial Intelligence has not finished talking about it….
