Hundreds of thousands of people have said goodbye to glasses thanks to this way

You have to limit or give up your favorite sport or job just because your nearsightedness is too severe. Or the funny situation is not being able to recognize friends and relatives from afar; even had to wear “double glasses” when going to 3D movies with “crush” at the theater.

Currently, refractive surgery is no longer a strange method for people with myopia and astigmatism. If you are wondering about the reduced quality of life, have a need to remove glasses due to work requirements, living habits, sports or aesthetic interests, choosing a safe refractive surgery method , surgery site, reputable doctor to prevent recurrence and long-term effectiveness should be considered. Here is some information about refractive surgery that we need to know.

PRK . method

The first generation of laser refractive surgery was PRK (Photorefractive Keratectomy). This is the first surgical method using the Excimer Laser to reshape the surface and help change the curvature of the cornea, thereby correcting the patient’s vision. Because this is a method of applying alcohol to the eye, it will lose the entire corneal epithelium, the postoperative period will be quite uncomfortable, the eyes will be swollen, painful, and uncomfortable for 1 to 3 days.

LASIK . method

LASIK (Laser Assisted in Situ Keratomileusis) is a method of correcting the curvature of the cornea by laser, thereby treating refractive errors. LASIK was born in the 1990s with a quick surgical procedure in 3 steps: creating a corneal flap – laser projection – resetting the corneal flap. LASIK surgery is painless and does not bleed; However, if you have problems with too thin corneas or severe dry eyes, you should not use this method.

Corneal parenchymal blade separation method

While the previous surgical technologies had to create a corneal flap with a cut of up to 20mm, the method of separating the parenchyma blade does not create a corneal flap. The femtosecond laser technology acts directly on the cornea, creating a parenchymal cut and a small incision, about 2mm, inside the cornea. The doctor easily splits the blade through a small incision, changing the shape of the cornea, helping to treat refraction for the patient. This is considered a minimally invasive surgical method, very safe and has the potential to limit complications.

Currently, CLEAR (Corneal Lenticule Extraction Advanced Refractive correction) technology is a new flap-free method of parenchymal blade separation in the treatment of refractive errors. This is a method that uses NanoJoule (nJ) ultra-low energy model to provide a smooth and complete cutting surface, minimizing damage to corneal tissues, helping to restore vision quickly. .

CLEAR does not create a corneal flap, thus preserving the absolute biomechanical stability of the cornea. Small incision minimizes corneal damage, minimizes dry eye after surgery, eliminates complications caused by flap surgery, has high accuracy and safety, does not recur. This is a method that is being evaluated by experts as a modern laser refractive error treatment method, with high accuracy, almost absolute safety, no complications and long-term effectiveness. Those who need to remove glasses add the optimal choice.

CLEAR technology is integrated on the FEMTO LDV Z8 surgical system – a device with iOCT optical tomography mode, helping doctors promptly detect problems other than refractive errors, thereby increasing accuracy. during treatment, ensuring patient safety. This system was developed by Ziemer Group – a medical device corporation from Switzerland, specializing in the field of ophthalmology with more than 24 years of experience. In the near future, the FEMTO LDV Z8 surgical system will be officially put into use in the treatment of refractive errors at the system of eye hospitals in Vietnam. CLEAR is expected to be the most modern and effective surgical method for the safe and quick treatment of refractive errors. This is a new development for the ophthalmology industry in particular and Vietnam’s healthcare in general.
