FV Hospital has introduced ClarityX – A new-generation refractive surgery technology integrated with artificial intelligence (AI). This system not only corrects common refractive errors such as myopia, hyperopia and astigmatism, but also effectively treats higher-order aberrations that cause glare, halos and image distortion, particularly when looking at night or in low-light conditions. As a result, it helps restore clear, sharp vision after surgery.

Effectively Treating Higher-Order Aberrations: Pain-Free and Blade-Free

H.T.K.Y. (19 years old) had suffered from severe myopia and astigmatism since childhood. Recently, she began experiencing bright flashes and glare when looking at objects at night, which caused her significant anxiety whenever she needed to go out in the evenings. On the recommendation of an acquaintance, Y. visited FV Hospital and consulted with Dr Nguyen Thi Mai, Specialist Level II, Head of Ophthalmology and Refractive Surgery, for examination and treatment.

Dr Mai explained that, in addition to having high degrees of myopia and astigmatism, Y. was also affected by higher-order aberrations, a condition causing glare, ghosting, halos or image distortion, particularly noticeable when looking at artificial light sources at night, such as street lamps or headlights.

Dr Mai prescribed treatment using the newly introduced ClarityX technology at FV. This is an ideal solution for cases involving higher-order aberrations, whether the patient has never undergone refractive surgery or has had previous surgery that did not address these aberrations. ClarityX is especially suitable for individuals who work in low-light environments, frequently work night shifts or drive at night, and those with high levels of astigmatism.

This is a fully laser-based, blade-free procedure that is safe and painless. The entire surgery for Y. lasted just 15 minutes, and she was discharged shortly afterwards. Within 24 hours, she noticed a remarkable improvement in her vision.

“Now I no longer have to wear those cumbersome glasses every day. Even more amazing is that I can see everything clearly, no blurrier vision, even when I had glasses on before. I haven’t been out much yet, but when I stood on the balcony looking down at the street, the lights were no longer glaring. That made me feel much more confident about driving at night,” Y. shared enthusiastically at her one-week follow-up after surgery.

ClarityX Technology: AI-Integrated and Personalised for Each Patient

The ClarityX technology, recently introduced at Ophthalmology and Refractive Surgery Department at FV Hospital, has immediately attracted significant public interest. According to Dr Nguyen Thi Mai, Specialist Level II, while conventional refractive surgery methods primarily focus on correcting myopia, hyperopia and astigmatism, ClarityX offers a distinct advantage: it can also address higher-order aberrations. As a result, it provides clearer vision and sharper image quality after surgery.

“ClarityX technology optimises the path of light within the eye based on a Wavefront map. A specialised device projects light waves into the eye and measures the reflections. This data is combined with artificial intelligence (AI) algorithms to create a detailed 3D map of the eye’s optical system, resulting in a personalised ‘design’ for each patient,” Dr Mai explained.

This technology is performed using the advanced Schwind Amaris 1050RS laser system, which can track eye movements across six dimensions and deliver laser pulses at a rate of up to 1,050 Hz. Treatment times are significantly reduced (≤1.3 seconds per dioptre), with micron-level precision, and the system supports multiple treatment modes including Aberration-Free, Wavefront-Guided, and Topography-Guided protocols.

Preoperative Screening: A Vital Step Before Surgery

To ensure refractive surgery is both safe and precise, the preoperative screening process plays a crucial role. FV Hospital is equipped with corneal mapping systems combined with biomechanical assessment of the cornea using the Oculus Corvis ST and Oculus Pentacam AXL devices. These technologies allow doctors to accurately determine key indicators of corneal strength, rigidity, and susceptibility to ectasia, while also detecting abnormalities at the earliest, subclinical stages. This makes it possible to reliably evaluate the condition of the patient’s cornea both before and after surgery.

The screening process also enables early detection of congenital eye conditions such as keratoconus, as well as other contraindications to surgery that conventional equipment may struggle to identify. “This is also the basis for doctors to select the most appropriate surgical method, minimise potential complications, and ensure patient safety,” Dr Mai added.

Refractive surgery at FV is performed by leading ophthalmology specialists, under the leadership of Dr Nguyen Thi Mai, Head of Department, who has over 30 years of experience and more than 30,000 successful refractive procedures. All surgical processes strictly adhere to the infection control and patient safety standards of Joint Commission International (JCI).

To mark the launch of this new treatment technology, FV is offering a special promotion from 5 May to 9 September 2025. The offer applies to advanced refractive surgery techniques available at the Department of Ophthalmology and Refractive Surgery, including personalised ClarityX treatment, Touchless SmartSurfACE laser, and flapless CLEAR procedures, with savings of up to tens of millions of VND.
