An Implantable Collamer Lens (ICL) and LASIK can both decrease dependence on glasses or contacts, but they correct vision in very different ways. LASIK reshapes your cornea with laser energy, while an ICL is a lens placed inside your eye without removing your natural lens. Your prescription, corneal anatomy, eye health, and vision needs all influence which choice makes more sense for you.
At Austin Eye’s Northwest and Westlake offices in Austin, TX, Shannon Wong, MD, John Odette, MD, and Max Medert, MD, evaluate people considering surgical vision correction and help determine which option fits their eyes. All three are board-certified ophthalmologists. Dr. Wong has performed more than 7,000 laser vision correction procedures, while Dr. Medert completed fellowship training in glaucoma and advanced anterior segment surgery.
How Do ICL and LASIK Correct Vision?
LASIK changes the cornea’s shape so incoming light can come into sharper focus on the retina. Austin Eye performs all-laser iLASIK, using one laser to create the corneal flap and an excimer laser to reshape the cornea.
An ICL works differently. The EVO ICL is placed behind the iris and in front of your natural lens. Because the cornea isn’t reshaped, the implanted lens supplies the refractive correction instead. Austin Eye uses ICL for nearsightedness and for some people who aren’t suitable candidates for corneal laser surgery.
Who Might Be Better Suited for ICL?
Prescription strength can make a major difference. ICL is an option for myopia ranging from about -3.00 to -20.00 diopters, including higher prescriptions that fall beyond the range of LASIK. It may also be considered when corneal surgery isn’t advisable.
Another distinction is that an ICL can be removed if necessary. LASIK permanently changes the corneal shape.
Because ICL involves surgery inside the eye, it also carries risks that differ from LASIK, including possible effects on the natural lens, cornea, or retina. A detailed eye examination helps your surgeon compare those considerations with the risks and benefits of laser correction.
What Makes Someone a Good LASIK Candidate?
LASIK may make sense when your prescription falls within an appropriate range, and your corneas can safely undergo reshaping. Austin Eye evaluates corneal thickness and mapping, vision stability, and general eye health before recommending iLASIK.
No single vision correction method is right for every set of eyes. A comprehensive evaluation gives you a clearer comparison based on your own prescription and anatomy rather than the advantages of either option in isolation.
