ICL vs. LASIK: Which One is Better for Whom?

When it comes to vision correction procedures, two popular options stand out: Implantable Collamer Lenses (ICL) and LASIK. Both offer effective solutions for achieving clear vision without the need for glasses or contact lenses.

However, the choice between ICL and LASIK depends on various factors, including the individual’s eye health, refractive errors, and personal preferences. In this article, we’ll delve into the details of ICL and LASIK to help you understand which one might be the better choice for your unique needs.

Understanding ICL and LASIK

ICL eye surgery and LASIK are both advanced vision correction procedures designed to address refractive errors and improve visual acuity. Both methods aim to reduce or eliminate the need for glasses or contact lenses, offering individuals the opportunity to experience clear and unaided vision.


ICL is a procedure that involves implanting a thin, biocompatible lens inside the eye to correct refractive errors such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. These lenses are made from a collagen copolymer material called Collamer, which is designed to be compatible with the natural tissues of the eye.

During the ICL procedure, a small incision is made in the cornea, and the lens is inserted behind the iris and in front of the eye’s natural lens. Once in place, the ICL corrects the way light focuses on the retina, improving vision.


LASIK is a laser eye surgery that reshapes the cornea to correct refractive errors. The procedure begins with the creation of a thin corneal flap using a microkeratome or femtosecond laser.

The surgeon then uses an excimer laser to precisely remove tissue from the cornea, reshaping it to achieve the desired refractive correction. After reshaping the cornea, the flap is carefully repositioned, and it adheres naturally without the need for stitches. The reshaped cornea allows light to properly focus on the retina, resulting in clearer vision.

Candidates for ICL & LASIK

To determine eligibility for LASIK, you can do a LASIK self evaluation test. However, for either procedure, it’s best to go to an eyecare specialist to get a professional opinion. Eye care professionals evaluate several factors to determine the suitability of each procedure for a patient:

  1. Refractive Error: The type and degree of refractive error play a significant role in selecting the most suitable procedure. ICL is often recommended for individuals with higher degrees of myopia or thinner corneas, while LASIK can effectively address a broader range of refractive errors, including myopia, hyperopia, and astigmatism.
  2. Corneal Thickness: Corneal thickness is a critical factor in LASIK candidacy. LASIK involves reshaping the cornea by removing tissue, so individuals with thinner corneas might be better suited for ICL. ICL does not alter the corneal structure and can be an option for those with thinner corneas or irregular corneal shapes.
  3. Age and Stability of Refractive Error: The stability of a person’s refractive error is essential. Younger individuals with rapidly changing prescriptions may be advised to wait until their prescription stabilizes before undergoing any vision correction procedure. Both ICL and LASIK are generally more suitable for individuals whose refractive error has remained stable for at least a year.
  4. Eye Health and Medical History: A comprehensive eye examination is conducted to assess the overall health of the eyes. Certain medical conditions, such as dry eye syndrome, glaucoma, or cataracts, can influence the choice of procedure. Individuals with conditions that might affect healing or recovery may be better candidates for ICL, as it does not involve altering the corneal tissue.
  5. Lifestyle and Visual Goals: The patient’s lifestyle and visual goals also play a role in selecting the appropriate procedure. LASIK eye surgery Kansas City typically offers faster visual recovery, while ICL may be more suitable for those seeking reversible vision correction or individuals at risk of dry eye symptoms.

Comparing Safety and Risks

The safety and risk considerations between ICL vs LASIK are very important. Both ICL and LASIK are safe procedures when performed by skilled and experienced eye surgeons.

The decision between the two should be made after a thorough discussion of individual health, lifestyle, and visual goals, along with a clear understanding of the potential risks and benefits associated with each option.

  • ICL is generally considered safe and has a strong track record of success. As the lens is placed behind the iris and in front of the natural lens, it doesn’t alter the corneal structure. This can be beneficial for individuals with thinner corneas, as no corneal tissue is removed.
  • LASIK is a widely performed and established procedure known for its effectiveness and relatively rapid visual recovery. The risks associated with LASIK are also generally low. However, it involves corneal reshaping, which might lead to temporary dry eyes and glare or halos around lights, especially at night.

ICL surgery is reversible, meaning the lens can be removed or replaced if needed, and it doesn’t induce dry eye symptoms as corneal procedures might. LASIK’s safety largely depends on the health of the cornea, and complications can include undercorrections, overcorrections, or corneal ectasia (weakening of the cornea).

Wrapping Up

ICL vs. LASIK: Which One is Better for Whom?

Ultimately, the choice between ICL and LASIK should be based on a thorough assessment of your eye health, refractive errors, and individual preferences. While ICL may be more suitable for individuals with certain refractive errors and eye conditions, LASIK offers a proven track record of success for a wide range of candidates.

It’s crucial to consult with an experienced eye care professional who can evaluate your unique needs and provide personalized recommendations.
