Is ICL Better Than Lasik?

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.
