Enhancing Your Vision
Guiding you toward the procedure that fits your unique needs, so you can see the world clearly and confidently.

Published: 20 Oct 2026
If you're trying to decide between LASIK, SMILE, EVO ICL, or lens replacement (RLE), it can feel like every website is quietly steering you toward the one procedure they sell.
In Manhattan, you're exposed to even more opinions: friends who had LASIK, influencers talking about SMILE, and ads for "implantable contact lenses" or "lens replacement in your 40s." It's a lot.
I'm Dr. Ilan Cohen, a cataract, cornea, and vision correction surgeon in New York. Over the past 25+ years, I've performed more than 80,000 procedures, including LASIK eye surgery in Manhattan, topography-guided LASIK, SMILE, EVO ICL, and lens-based surgeries like Refractive Lens Exchange (RLE).
This article is the written version of how I actually think through your options in the exam room. By the end, you should know which "lane" you belong in, and which procedures you can safely ignore.
There are only two main structures we can work on to change your focus:
Most procedures fall into one of two categories:
If the window (cornea) is the main issue and the lens is young and healthy, we usually stay on the cornea.
If the lens is aging, or will soon become the problem, lens-based options deserve serious consideration.
When I evaluate someone in our Manhattan office, I'm mentally running four filters:
We look at:
If the cornea is thin, irregular, or already stressed, we may avoid LASIK or SMILE and move toward PRK or lens-based options.
This is where many patients, and some surgeons, skip too quickly.
If you hate the idea of reading glasses after 50, lens-based options (especially RLE with advanced lenses) must be part of the conversation, not an afterthought.
Once you're in the "cornea lane," we compare the tools we have to reshape the window.
LASIK reshapes the cornea under a thin flap created by a femtosecond laser or microkeratome. It can correct myopia, hyperopia, and astigmatism and has fast recovery with minimal discomfort for most patients.
At Cohen Eye Institute, we use all-laser, bladeless LASIK with advanced diagnostics to personalize the treatment, as outlined on our LASIK eye surgery page.
For a typical 20s–30s myope with a healthy cornea, LASIK or Contoura/FAZE LASIK is often the most efficient, time-tested choice.
Topography-guided LASIK (Contoura) uses thousands of data points from your corneal surface to refine the laser pattern. This helps smooth subtle irregularities that can otherwise cause glare, halos, or night-vision issues.
FAZE™ LASIK is our proprietary approach built on this same idea, using topography and customized laser patterns to treat both regular and hidden astigmatism more precisely than standard LASIK.
For research-oriented patients with meaningful astigmatism who care a lot about night driving, FAZE™ or topography-guided LASIK is usually superior to standard LASIK or SMILE.
👉 If you're comparing options, our FAZE™ page and topo-guided LASIK overview go into more technical detail.
With PRK, we gently remove the surface epithelium and reshape the cornea without creating a flap. The surface then regenerates over several days.
Trade-offs:
If your cornea is slightly thin or borderline but otherwise healthy, PRK can be the safer way to get LASIK-like results.
SMILE is a small-incision procedure that removes a lenticule of tissue through a tiny opening. It treats myopia and some astigmatism, but currently does not treat hyperopia in the U.S.
Reality check for "researcher" patients:
At Cohen Eye Institute, we offer SMILE, but for many Manhattan patients who qualify for Contoura/FAZE LASIK, SMILE doesn't offer a clear advantage, and sometimes removes helpful tools (like topo-guided customization) from our toolbox.
If your cornea is not an ideal target, or your age and reading goals point us toward the lens, we move to the "lens lane."
EVO ICL is a thin, biocompatible lens placed behind the iris and in front of your natural lens. It corrects high myopia (and astigmatism in toric versions) without removing corneal tissue.
Who ICL is great for:
ICL risks include rare but real issues like elevated eye pressure and earlier cataract formation, which we minimize with careful sizing, anatomy checks, and follow-up.
You can read more on our EVO ICL page.
RLE is essentially cataract surgery done earlier:
For someone 50+ in Manhattan who:
RLE often makes more sense than trying to "perfect the window" (LASIK) in front of a lens that is already on its way out. This is the same logic behind our premium cataract surgery and multifocal lens strategies, just done before the lens fully clouds.
A common scenario:
Could we do LASIK?
Yes. Distance would likely be sharp. But:
We'd be polishing the window in front of a lens that's already the weak link.
With RLE, we:
For many "Laura-type" patients, RLE is the only option that can permanently address both distance and near in one step.
Very simplified, but useful:
If you'd like to sanity-check your own candidacy, our LASIK eligibility guide and Manhattan LASIK alternatives page are good companion reads.
Every procedure has trade-offs. For a "researcher" patient, you should know at least:
Red-flag symptoms after any surgery that should trigger an immediate call:
We review these carefully before any procedure and provide written instructions and direct contact info for our Manhattan, Queens, and New Jersey locations.
You can literally bring this checklist to a consultation:
At Cohen Eye Institute's Manhattan location, we deliberately offer both:
If you're the "researcher" type, you're not asking for too much when you say:
"I want sharp distance and functional near vision with a plan that makes sense for my age and my corneas."
That's exactly what our proprietary tools like RealSight™ (for lens planning) and FAZE™ (for astigmatism correction) were built to do.
When you're ready, you can start with a consultation or take our refractive surgery quiz to see how your age, prescription, and goals line up with your options.
All four are safe in proper candidates, but the "safest" choice is the one that fits your age, cornea, and lens health. For thin or irregular corneas, EVO ICL or RLE may be safer than LASIK/SMILE. For early presbyopes, RLE may avoid multiple surgeries later.
There's no strict cutoff, but after 50, many people are better served by RLE or advanced cataract-style solutions because the lens is already aging and will eventually need to be replaced.
SMILE uses a smaller incision and may have slightly less dry eye early on, but it has a narrower prescription range and doesn't treat hyperopia. For many patients who qualify for topography-guided or FAZE LASIK, SMILE doesn't provide a clear long-term advantage.
EVO ICL is often better for high myopia, thin/borderline corneas, or when we want to avoid further corneal thinning. It lets us correct vision while keeping your cornea structurally intact.
If you're 50+, already struggling with readers, and highly motivated to be glasses-independent, RLE can treat both distance and near vision and prevent future cataract surgery on that eye. The trade-off is that you're choosing surgery earlier in exchange for fewer surgeries overall.
Look for a surgeon who:
