Sisters from Thailand: How Flow3 Changed Their Vision

We met two remarkably cheerful sisters at KSA Silmakeskus—Shreya and Suhani—who uprooted their lives from Thailand, relocated to Estonia, and recently made a life-changing decision together: they ditched their glasses with Flow3 laser eye surgery.

What brought them halfway across the world? And what sparked the idea to free themselves from glasses as a team? Here's their story.

A bond forged from childhood

Shreya and Suhani have been inseparable since early childhood. They've lived through virtually every major milestone side by side—and their connection runs deep.

"I think we're so close because we've gone through so many life stages together," says Shreya, the elder sister. "We know we can always count on each other."

Suhani adds: "Since Shreya is four years older, she's been there for all my big and small moments. We have an incredibly strong bond."

That bond was forged in an unlikely place: boarding school. When Shreya was just eight and Suhani only four, their parents sent them both to a boarding school in India. They could only see their family 45 days a year.

By any measure, that's a tough childhood—but it had an unexpected effect. "We had to rely entirely on each other," Suhani explains. "It made us closer in ways most siblings never experience. And honestly, that unconventional upbringing taught us resilience and independence."

From India to Thailand to the world

After finishing secondary school in India, both sisters moved back to Thailand, where they spent their university years together. Suhani studied international relations; Shreya took on international business and finance.

But for their master's degrees, they split—temporarily. Suhani moved to the UK; Shreya headed to Germany. For the first time in their lives, they were apart for an extended period.

Then came the pivotal moment.

Suhani received a job offer from Bolt in Tallinn, Estonia. Without hesitation, she packed her belongings—saying goodbye to Bangkok's 10 million people, tropical heat, and her beloved dog Cheeto—and relocated to one of Europe's smallest capitals.

"The first weeks were lonely," she recalls. "My family, my dog, my entire life was thousands of kilometres away."

But the story doesn't end in separation. Shreya received a job offer at Bolt too. Within months, both sisters were reunited at Tallinn Airport, this time with Cheeto in tow, ready to start a new chapter together.

From Bangkok to Tallinn: A stark contrast

The jump from a tropical megacity to a Nordic capital city is jarring. When we asked what they miss most about Thailand, the answer came immediately—and in unison.

"Food," they both laughed. "Thai street food is incomparable. The aromas, the spices, the flavor combinations—nowhere else in the world serves it like Thailand does. Pad Thai is my absolute weakness," says Shreya. "And the fresh fruit and vegetables! Even in our first Estonian winter, we were missing tropical produce."

But adjusting to life in Tallinn went beyond cuisine. Shreya and Suhani were also adjusting to something else: the Estonian climate and its demands on the eyes.

Why they chose Flow3

Both sisters had worn glasses for years. The Tallinn winter—with its long dark days, harsh light reflecting off snow, and the constant need to adjust frames—prompted them to explore alternatives.

That's when they discovered Flow3 at KSA Silmakeskus.

Flow3 is a flapless surface laser treatment. Unlike traditional LASIK, which creates a corneal flap that must be lifted, Flow3 works on the eye's surface directly. This means:

• No corneal flap—the eye remains structurally intact
• Faster healing—typically one week for functional vision
• Ideal for active people—there's no flap to displace during sports or physical activity
• Lower infection risk—the eye's natural barrier stays completely undisturbed

For two sisters who'd spent their lives staying active together—from boarding school to international careers—the safety profile of Flow3 was compelling.

"We wanted something reliable and safe," Suhani explains. "Flow3 felt like the natural choice, especially knowing the entire clinical team at KSA trusts it enough to have had the procedure themselves. That's the kind of proof you can't argue with."

She's right. The fact that Dr. Ants Haavel and the entire clinical team chose Flow3 for their own vision speaks volumes. Over 55,000 procedures performed. Two decades of expertise. And the specialists who know the technology best trust it with their own eyes.

A week after their procedures, both sisters had clear vision—and they were back to their lives without the friction of glasses or contacts.

The next chapter

For Shreya and Suhani, Flow3 wasn't just about seeing better. It was another chapter in a lifelong story of facing challenges together—this time, in a small Nordic country far from home, with clearer eyes to see their future.
