At Kelly Laser Center, our New York, Manhattan, and Long Island eye doctors offer many types of refractive eye surgery, including LASIK, but also lens implant surgery. In this procedure, an additional lens, sometimes described as a “helper” lens but more technically known as a phakic intraocular lens (IOL), is inserted either in front of or behind your eye’s iris. This lens is able to correct your eye’s natural refractive error so light is properly focused on the retina, leading to clear vision.
These lens implants are a great option for people with nearsightedness who either are not candidates for LASIK or would rather not have LASIK. Some people may even have better vision with these implantable lenses than with LASIK. To learn whether you are a candidate for phakic IOLs, please call 855-328-0201 or email us today to schedule a consultation at the Manhattan, NYC location ofKelly Laser Center.
Understanding Implant Lens Technology
Clear vision depends on light focusing directly on the retina, which receives the light and translates it into electrical impulses that are sent to the brain. However, when you have refractive errors, such as myopia, your eye’s two lenses, the cornea and the crystalline lens, are not able to focus light on your retina. There are two solutions to this problem: use additional lenses to achieve the appropriate focus or reshape one of the lenses (the cornea) so the focus is right. The first approach has long been used in glasses and contact lenses, and now includes implantable lenses.
Implantable lenses work the same as glasses or contacts: they give your eye additional focusing power. Only, instead of being on the outside where they need cleaning and can be broken, scratched, or lost, they are inside your eye. They become part of your eye and you’ll forget they’re there.
At Kelly Laser Center, our New York area eye doctors use two types of implant lens technologies: Visian ICL and Verisyse. Both are approved for use in treating myopia (nearsightedness), and we generally use them only for treating severe myopia, but in the future they may be available for hyperopia and astigmatism.
Visian ICL Technology
The Visian Implantable Collamer Lens (ICL) is unique not only in its design, but also in its materials. Visian ICL is designed to be placed behind your iris, where it is invisible to you and to others. Visian has a foldable design that allows it to be placed via a smaller incision. Visian is made of Collamer, a proprietary material exclusive to Staar Surgical Company, which, according to the manufacturer, has many superior properties. Increased transparency to visual light, reduced glare, and absorption of UV light are all optical benefits of Collamer.
Verisyse works in a very similar fashion to Visian, but with a couple of minor differences. Instead of being placed behind the iris, Verisyse is placed in front of the iris, which gives it greater stability, decreasing the likelihood that the lens will move, which would require and additional surgery to correct. Verisyse is made of PMMA, a type of plastic that is used in many monofocal intraocular lenses used in cataract surgery, and some advanced intraocular lenses, such as ReSTOR. It is a material that your body readily accepts.
Results of Implantable Lens Surgery
Phakic IOLs generally give very good results, comparable to LASIK in many ways and superior in others.
There are some potential complications associated with implantable lens surgery. These include the possibility of cataract formation, retinal detachment, and transient spikes in intraocular pressure that can be treated with glaucoma medication. During your consultation, we can provide you with the clinical data and talk to you about our personal experience with these lenses.
