Implantable collamer lens or ICL, called by its manufacturer Visian ICL, is a soft, flexible gel-lens used in refractive surgeries for the permanent correction of myopia (nearsightedness), made of a collagen copolymer material, named by combining "collagen" and "polymer". The ICL procedure is a popular alternative to LASIK and PRK since it requires no removal of the corneal tissue and reportedly produces better visual results.
The ICL procedure is a type of refractive surgery performed by an ophthalmologist in which the ICL is surgically implanted inside the eye, where it resides permanently. The ICL requires no maintenance after the procedure and functions very similarly to contact lenses in improving visual acuity. For most patients, ICL provides permanent freedom from eyeglasses or contact lenses.
With the Visian Implantable Contact Lens, you can achieve high-definition vision without many of the risks associated with LASIK. Rather than changing the shape of the cornea as in LASIK eye surgery, implantable lenses are placed inside the eye to enhance the focusing abilities of the eye?s natural lens, providing excellent quality of vision for a wide range of vision correction. Should your prescription change, the lens is replaceable to maintain your vision for years to come.
Suitability criteria for ICL candidate
Candidates for the ICL are above 18 years of age, suffer from myopia (nearsightedness), hyperopia (farsightedness) and/or astigmatism (Cylindrical power) and want to experience superior vision correction.
Candidate with refractive error who are unsuitable for laser refractive surgery.
Prospective person should consult his/her ophthalmologist (eye surgeon) for more information, including an assessment of their candidacy.
Women who are pregnant or nursing should wait to have the ICL implanted. Lastly, those without a large enough anterior chamber depth or endothelial cell density may not be a good ICL candidate.
