Vision correction has come a long way from the early days when there was only one option with lengthy recovery times. Procedures today are faster, more comfortable, and more precise than ever before.
But with innovation comes choice, and choice requires knowledge. Let’s explore what each of today’s five main modern vision correction procedures offers and help you determine which aligns best with your vision goals!

What is Modern Vision Correction?
Modern vision correction refers to advanced surgical procedures that aim to reduce or eliminate your dependence on glasses and contact lenses. These procedures work by reshaping parts of your eye or replacing or adding to natural structures to correct common vision problems like nearsightedness, farsightedness, and astigmatism.
The key to successful vision correction lies in choosing the right procedure for your specific needs. Factors such as your age, prescription strength, corneal thickness, lifestyle, and personal preferences all play a role in determining which option will yield the best results.
LASIK
LASIK is one of the most well-known vision correction procedures. During LASIK, your surgeon creates a thin, hinged flap in the clear front surface of your eye (the cornea). This flap is gently lifted, and a precise laser reshapes the corneal tissue underneath according to your specific prescription. The flap is then repositioned, where it acts like a natural bandage.
LASIK works best for people with mild to moderate nearsightedness, farsightedness, or astigmatism. You’ll need adequate corneal thickness to safely create the flap, and your prescription should be stable for at least a year before the procedure. Most LASIK patients return to their normal activities within a day or two, making it an attractive option for busy professionals and parents.
PRK
PRK, or Photorefractive Keratectomy, was actually the predecessor to LASIK and remains an excellent option for many patients. Instead of creating a flap, PRK involves gently removing the thin outer layer of the cornea before reshaping the underlying tissue with the same precise laser used in LASIK.
While PRK and LASIK achieve similar visual results, the recovery process differs. Since there’s no flap involved, PRK takes a few days longer to heal initially, but the final visual outcome is just as impressive as LASIK.
PRK is ideal for people with thinner corneas who might not be good candidates for LASIK. It’s also preferred by individuals in high-impact professions or those who participate in contact sports, since there’s no flap that could potentially be displaced by trauma to the eye.
EVO ICL
The EVO Implantable Collamer Lens represents a newer approach to vision correction that doesn’t involve reshaping your cornea at all. Instead, this ultra-thin lens is placed inside your eye, between your natural lens and iris, where it works with your existing lens to provide clear vision.
Unlike corneal procedures, the EVO ICL is removable if your vision needs change in the future or if new technologies become available. The EVO ICL is particularly beneficial for younger patients (ages 21-45) with moderate to severe nearsightedness, especially those whose corneas are too thin for LASIK or PRK.
The lens includes built-in UV protection and often provides excellent night vision quality. Many patients appreciate having a reversible option that doesn’t permanently alter their corneal structure.
SMILE
SMILE (Small Incision Lenticule Extraction) is one of the newest vision correction procedures, offering a minimally invasive alternative to traditional laser surgery. During SMILE, a laser creates a small, lens-shaped piece of tissue within the cornea, which is then removed through a tiny incision about 2-4mm long.
What makes SMILE unique is that it doesn’t require creating a large flap like LASIK. SMILE is currently approved for treating mild to moderate nearsightedness with or without mild astigmatism.
It’s an excellent choice for active individuals who want the benefits of laser vision correction without concerns about flap-related complications.
Refractive Lens Exchange
Refractive Lens Exchange (RLE), which is very similar to cataract surgery, replaces your eye’s natural lens with an artificial lens implant. This is essentially the same procedure used for cataract surgery, but it’s performed before cataracts develop to correct vision problems.
RLE is particularly valuable because it can address multiple vision issues simultaneously. With advanced lens implants, many patients can see clearly at distance, intermediate, and near ranges, reducing or eliminating their need for both distance glasses and reading glasses.
RLE typically works best for patients over 45 who are starting to experience presbyopia (difficulty with near vision) or who have early signs of cataract development.
How Do I Know Which Vision Correction Procedure is Right for Me?
Choosing the right vision correction procedure isn’t a one-size-fits-all decision. Several factors influence which option will work best for your unique situation:
Your age plays a significant role. Younger patients (18-40) often benefit most from corneal procedures like LASIK, PRK, or SMILE. Those over 45 might find RLE more advantageous since it addresses both distance vision and the natural aging changes that affect near vision.
Your prescription strength is another key factor. Mild to moderate prescriptions typically respond well to corneal reshaping procedures, while very high prescriptions might be better suited for lens-based solutions like EVO ICL or RLE.
Corneal thickness and shape determine whether flap-based procedures like LASIK are safe for your eyes. If you have thin corneas, PRK or lens-based procedures might be better options.
Your lifestyle and profession also matter. If you’re involved in contact sports or high-risk activities, flapless procedures like PRK or SMILE might be preferable. If you have concerns about dry eyes, certain procedures may be more suitable than others.
Your long-term vision goals should be considered too. If you want to address both distance and near vision, or if you want to prevent future cataract surgery, RLE might be the most comprehensive solution.
