At 15, Phat suffered an injury that resulted in a traumatic cataract in his left eye, reducing his vision to just 10%. He had to wait until he was 18 to undergo cataract surgery. Dr. Tang Ngoc Anh, deputy head of the Ophthalmology Department at Tam Anh General Hospital's High-Tech Eye Center in Ho Chi Minh City, explained that cataracts typically develop after the age of 40, with vision significantly deteriorating after 60 due to the natural aging and clouding of the eye's lens. Phat's case, however, was a result of trauma, not age-related degeneration.

Examinations revealed cataracts in the anterior cortex (the part closest to the cornea), the nucleus, and the posterior cortex (adjacent to the crystalline lens and retina), but thankfully, no rupture of the lens capsule. This minimized the risk of inflammation, complications, and further damage.

"This was a complex case of post-traumatic cataract surgery in a young patient," Dr. Anh said. The delay of several years caused changes within the eye, making the lens not only cloudy but also harder and more firmly attached to the capsule. This increased the risk of capsular rupture and lens displacement during surgery.

Dr. Anh opted for phacoemulsification, a technique using high-frequency ultrasound to break up the cataract, combined with the implantation of a multifocal intraocular lens (IOL). This allows patients to see clearly at both near and far distances without glasses. Barring any complications, multifocal IOLs can last a lifetime, unlike natural lenses, which can degenerate with age, and don't require replacement like regular eyeglasses.

Phat was advised to limit screen time, rest his eyes, avoid getting water in them for two weeks post-surgery, wear sunglasses outdoors for protection against dust and UV rays, and attend follow-up appointments.

Following the surgery, Phat's left eye vision improved to 90%. His right eye has astigmatism, and Dr. Anh recommended regular check-ups and corrective lenses, especially for extended computer use. Future surgery for the astigmatism is an option.
