The Visian ICL (Implantable Collamer Lens) is a lens implant, which is capable of correcting extremely large amounts of nearsightedness (ranging from –3.0 D to –20.0 D), which is well beyond the treatment range of LASIK (up to -12.0 D). The soft, flexible nature of the Visian ICL allows it to be inserted through a self-sealing micro-opening that measures only ~2 millimeters. The Visian ICL is designed to stay permanently, but it could be removed or updated, if necessary. The lens is made of a material called Collamer, which filters ultraviolet light and is very well-tolerated within the eye.
Like a soft contact lens: Visian ICL is soft & flexible
The U.S. FDA approved the Visian ICL in 2005 after reviewing the long term data since 1995. In the FDA clinical studies, 526 eyes underwent the lens implant procedure, averaging -10 D of preoperative nearsightedness. Three years after the procedure, nearly 95% of patients had “20/40 vision or better” without glasses, which is good enough to pass the DMV test (4). These are remarkably good results considering the extremely high level of nearsightedness that was treated.
Like LASIK: The Visian ICL procedure is painless
Lens implants/inserts have been used for over half a century in various forms of eye surgery, such as cataract surgery. With the Visian ICL, the eye’s natural lens is left in place. The lens implant procedure is done as an outpatient procedure, under topical eye drop anesthesia. Most patients experience little to no discomfort during the actual procedure, which takes about 15-20 minutes. Most patients report a nearly instantaneous improvement in their vision within hours, similar to LASIK.
Like nothing: It doesn’t require any daily care, and can’t be seen or “felt”
In the FDA clinical studies, 93.6% of patients (averaging -12.6 D nearsightedness) saw “20/40 or better” without glasses one year after the procedure. At three years after the procedure, 92% of patients had uncorrected vision of “20/40 or better”, and 61.7% were seeing “20/25 or better” without any glasses (1). In a recent study published in the scientific journal Ophthalmology, for the treatment of extreme nearsightedness (between – 9.00D and –19.50D), 72.2% of patients who received underwent lens implants in one eye and LASIK in the other preferred the vision in the lens implant eye over the LASIK eye because of the better quality of vision (3).
