We get it, medical terms and eye surgery terminology sound strange and terrifying . “Flaps,” “Excimer,” “Lenticules”… it sounds like sci-fi. But you know what isn’t scary? A Vada Pav.

In this genius short video from Shroff Eye Centre, Dr. Rushad Shroff takes one of his favorite snacks and turns it into the perfect anatomy/ eye surgery lesson. If you’ve ever been confused about the difference between SILK, SMILE, LASIK, and PRK, this “delicious” explanation is exactly what you need.

Here is the step-by-step breakdown of the video (and yes, a Vada Pav was harmed in the making of this video & blog).

The Vada Pav Analogy: Understanding SILK, SMILE, LASIK & PRK in Simple Terms

The Vada Pav = Your cornea: The vada pav acts as the top layer of your eye called the Cornea (the front transparent part in front of your eye).

The Goal: Reshaping the cornea to correct your vision so you don’t need glasses.

Let’s explore laser vision correction!

Here is exactly what happens in the video, translating the snack-tion into medical facts.

In the video, Dr. Rushad Shroff uses a simple Vada Pav analogy to explain how laser vision correction works. He compares the bun to the cornea, which is the clear front surface of the eye where all laser specs removal procedures are performed.

The Treatment Techniques:

• SMILE/SILK: The “Keyhole” surgery (no flap).
• LASIK: The “Flap” surgery (lift and treat).
• PRK/ Streamlight: The “Surface” surgery (no flap, surface remodelling).

Technique 1: The “Keyhole” Method (SILK, SMILE, CLEAR or any lenticular extraction procedure for specs removal)

Visual: A laser pointer highlights the center of the bun. The doctor uses forceps to reach inside the bun and pulls out a tiny piece of the filling.

What Actually Happens in SILK/ SMILE/ CLEAR: The femto laser creates a microscopic disc (lenticule) inside the cornea layers and a tiny keyhole incision on top. The eye surgeon removes this disc through a tiny keyhole incision. This corrects the shape of the cornea and corrects eye power.

Why it’s cool: No flaps! It’s minimally invasive with quick recovery and great for those with active lifestyles.

Technique 2: Blade-Less LASIK (Covers procedures such as Wavelight, iLASIK, Schwind Amaris)

Visual: The top half of the bun is cut with laser (with one laser) and lifted up like a flap. The second laser treats the corneal layers below (pav), and the bun top is put back.

What Actually Happens in Wavelight Contoura, iLASIK, Schwind Amaris: A femtosecond laser creates a thin flap on the top layer of the cornea. We lift it, reshape the cornea underneath with an excimer laser to fix your eye power, and put the flap back. Flap heals, seals and eye power is corrected.

Why it’s cool: Fast recovery. You see clearly almost immediately.

Technique 3: Streamlight PRK (popularly called Touchless LASIK or TransPRK)

Visual: The top “skin” of the bun is completely removed by the laser, the inside is treated by the laser, and healing requires we wait for the skin to grow back.

What Actually Happens in Streamlight PRK (popularly called Touchless LASIK or TransPRK): There is no flap. A laser precisely removes the ultra-thin top layer (epithelium) of the cornea and a second laser reshapes the underlying cornea. The epithelium grows back naturally in a few days, correcting eye power.

Why it’s cool: Great for people with thin corneas or active sports lifestyles.

Technique 4: Conventional PRK (EpiContoura)

Visual: A chemical is applied to the bun to loosen the top skin of bun, which is then removed and the lower layers are then treated by another laser

What Actually Happens in: Similar to Streamlight, but instead of a laser removing the top layer or epithelium, a safe chemical solution is used. The laser then corrects the power by treating the underlying cornea, and the eye power is corrected once this epithelium heals naturally.

Technique 5: Blade LASIK (The old classic)

Visual: A physical blade tool lifts the bun flap and the laser treats the part underneath.

What Actually Happens: A device called a Microkeratome (a kind of blade) creates the corneal flap instead of a femto laser. The excimer laser then corrects the shape of the cornea. The flap is replaced and it heals naturally.
