How Do Doctors Decide Between PRK, SMILE and LASIK Eye Surgery?

Ever wonder how your eye doctor picks the right surgery just by looking at your prescription? We will break it down today and let you know how and what surgery would suit you better, and how doctors or surgeons decide what would suit your eyes.

What are PRK, SMILE or LASIK?

Now, let's again explain this in detail. What surgeries are we talking about here?

LASIK:

LASIK, which uses a laser, is a very common procedure. Here’s how it’s done:

1. The doctor creates a thin flap on your cornea
2. A laser reshapes the tissue underneath
3. The flap is placed back to heal naturally
4. Recovery is quick, and people see clearly within 1 or 2 days

SMILE:

SMILE is one of the latest and most modern Technologies for laser eye surgery. Now, let’s consider in detail how it works:

1. No flap is created
2. The laser makes a tiny 2-4mm cut
3. A small piece of tissue is removed through this opening
4. Less dry eye compared to LASIK
5. If you have an active lifestyle, it would suit you best

PRK:

PRK is one of the oldest and yet best alternative for LASIK eye surgery. Here’s a simple explanation:

1. The outer layer of the cornea is removed
2. A laser reshapes your cornea
3. No flap is created
4. Recovery takes longer (3-5 days)
5. Best for thin corneas or people in sports/military

This is how Doctors make the decision:

The doctor reviews your prescription and decides as he checks your corneal thickness, eye health, eye power, and any past eye problems.

1. Corneal Thickness

   The cornea is the front part of the eye. The doctor correlates his/her findings from eye thickness to the surgery to be done. The procedure that is to be done depends on the thickness of your eye, as each of them requires a different thickness of the eye to be able to correct your vision. Below is the matter of corneal thickness needed for PRK, LASIK and SMILE:

   • PRK – 480+ corneal thickness
   • LASIK – 520+ corneal thickness
   • SMILE – 520+ corneal thickness

2. Eye Power

   Eye power is also one of the most important things. Eye power needs to be stable for at least 1 year, and different levels of eye power need different types of surgeries. Not every kind of surgery supports every level of eye power.

   • PRK - -7 or -8 would work, but the recovery might be a bit slow
   • LASIK - -1 to -7 would work and is preferred
   • SMILE - -6 would work perfectly

3. Eye Health

   Your overall eye health is very important, as any injuries in the past or scratches or any condition can really harm your eyes. So surgeons check your eyes multiple times before going into the surgery.

4. Type of vision problem (Myopia, hyperopia, and Astigmatism)

   Surgery also depends on what type of sight you have. If you have myopia, most of the surgeries support it, but not in the case of other kinds of sight. Let's break it down:

   Myopia (near-sightedness)
   • Low (up to -3.00): Any type of surgery should be fine
   • Moderate (-3.00 to -6.00): LASIK and SMILE are good choices
   • High (over -6.00): LASIK is often preferred, but your cornea’s thickness is a big factor
   Farsightedness (Hyperopia):
   • LASIK can treat hyperopia the best up to +6.00 power
   • PRK can treat hyperopia up to a mild or moderate level of power
   • SMILE can’t treat hyperopia

   Astigmatism (blurry or distorted vision at all distances)

   • Mild (up to -2.00): All surgeries can work well
   • Moderate or High Astigmatism (above -2.00) – LASIK provides the best result
   • Combination of Astigmatism and Myopia – LASIK and PRK would be preferable
   • Irregular Astigmatism – PRK would be safer

5. Age and Eye Health

   Your age and overall eye condition play a role, too.

   Under 40 with healthy eyes:
   • All options are available
   • LASIK is the most common
   Over 40 with early presbyopia:
   • Monovision LASIK might be suggested
   • One eye corrected for distance, one for reading
   Previous eye surgery or injury:
   • PRK might be safer
   • No risk of flap complications

6. Healing Time

   Your lifestyle and work life would also decide what kind of surgeries would suit you. Your active or laid-back lifestyle decides how early your eyes can heal, and that kind of surgery is given to you.

   LASIK
   • Your vision gets better within 24 hours
   • You can get back to work within 2 or 3 days
   • It is the best solution for working professionals or busy individuals
   PRK
   • You will recover 90% of your vision on the day of surgery
   • You can get back to work within 4-5 days
   • This is the best solution for people who can take time out and have patience
   SMILE
   • You will recover 90% of your vision on the day of surgery
   • You can get back to work within 1-2 days
   • It is the best solution for working professionals or busy individuals
