Is ICL Better Than Lasik?

The ICL is a rapid, procedure used to implant a lens inside the eye to correct high nearsightedness. This procedure does not involve removal of tissue nor reshaping of the cornea, thus, the quality of vision has been shown in several studies to be better than LASIK for high prescriptions.
The ICL offers another procedure in the doctor's "bag" to correct refractive errors or prescriptions of the eye. It is important to seek the care of an eyeMD to determine which procedure is best for you.

Lasik will always be the gold standard for laser vision correction, although Contact lens implants are also great. You should look into the type of lasers available in your area. I am the only surgeon in Michigan routinely performing CATz lasik which is the most advanced form. If your surgeon is using CATz then lasik is great, if they are using an older style laser, I believe the ICL should be considered. There many benefits to ICL as well including the fact that it will void any risk of cataracts as your natural lens is removed. An experienced surgeon should be be able to help you decide which is best for you, during a consultation

I agree with most of these posts.  Refractive surgery is not a one-size-fits-all solution.  For most of these inquiries ("which procedure, if any, is right for me"), the answer depends on age, general eye health, expectations following the procedure and safety profile of each procedure.  Furthermore, I will often encourage my patients to have the procedure that will last the longest (lifetime, if possible).  That way, this can be a one-off procedure. We have a lot of exciting technology at our fingertips. The more tools your surgeon has, and the more experience/expertise he or she has in using those tools, the better your result is typically going to be.  Lastly, I highly recommend a thorough consultation with your surgeon to discuss risks and realistic expectations.  In other words, these are your eyes. Don't undervalue face-to-face discussion about your options with your surgeon.

ICL should not be considered an inferior alternative to LASIK. It very frequently produces quality of vision superior to that of LASIK or PRK especially for higher prescriptions. This is possible for 2 reasons:The ICL doesn't change the corneal shape, thus preserving the natural corneal a-sphericity. Corneal a-sphericity is what gives us the ability to see in high contrast day or night, as it compensates for the so called spherical abberations. The best camera lenses are always aspheric.ICL produces crisper vision because it is physically closer to the retina than the corneal refractive procedures. As anyone who ever tried to cast a shadow puppet knows, the closer you are to the surface on which the shadow/image is projected the sharper and better defined the image. Hence, quality of vision increases in the following order - glasses < contacts < LASIK < ICL since the refractive element that corrects the vision is progressively closer to the retina. 

There are is no best surgery to correct vision, there is only the best surgery for you. Your goal should be to find a doctor who specializes in refractive surgery and is comfortable will all the different procedures available. Once you have found a doctor, have a discussion of the pros and cons of each surgery as they relate to your eyes and make a decision together.

Both LASIK and ICL have advantages and disadvantages.  Neither is superior to the other in all cases and a surgeon who performs both will advise individual patients which treatment would be preferred and the reason for that preference.  High prescriptions would begin to favor ICL particularly for patient with large pupils and/or thin corneas.  Low prescriptions would tend to favor LASIK.  A comprehensive eye examination would be necessary to advise a patient which treatment would be best for them.  A patient could then be involved in weighing the advantages of the various options as well as the option of using glasses or contacts.
