Lens Implants

Verisyse™ and ICL

Lens Implants | Encino CA | West Hills CAThe Verisyse™ phakic intraocular lens can be surgically implanted in the eye to improve vision in patients with severe nearsightedness. Most of these patients are not candidates for other corrective treatments such as LASIK because their corneas are too thin and their prescriptions are too high. These patients are often resigned to wearing thick glasses or contact lenses.

The cornea acts a lens in the front of the eye, bending light rays so that they focus on the retina. In nearsighted patients the cornea is elongated or steepened, so light rays focus in front of the retina and patients suffer from blurry vision. The Verisyse™ IOL is implanted on the iris behind the cornea to correct the way light is focused and to improve vision. The cornea is left in place to retain the ability to focus between near and distant objects. The procedure is outpatient and takes 15-30 minutes under local anesthesia. The next day, patients notice an incredible difference.

The Verisyse™ IOL has been used in over 150,000 procedures worldwide with precise and predictable results. The lenses are made with PMMA, the material used in cataract surgery for the last 50 years. Please schedule an appointment or consultation to find out if the Verisyse™ lens is right for you. Candidates should be over 21, have good eye health and stable vision, and should not be pregnant or nursing.

ICL (Intraocular Contact Lens/Visian) are a different type of phakic intraocular that can also correct extreme nearsightedness. They are made of the same material used for lens implantation during cataract surgery, but the contact lenses are actually placed on top of the patient's crystalline lenses.

Refractive Lens Exchange - Clear Lens Extraction

LASIK is able to correct virtually all levels of nearsightedness, farsightedness, and astigmatism. However, some patients who are too nearsighted for LASIK, are better candidates for a Phakic IOL (Verisyse or ICL). Furthermore, some farsighted patients are better candidates for Refractive Lens Exchange/Clear Lens Extraction. Two types of farsighted patients benefit from this procedure which is really no different from standard cataract surgery. The first type is patients who are too farsighted for LASIK. The second is middle aged farsighted patients who want to eliminate or reduce the need for bifocals.

Phakic Intraocular lenses are implanted in front of the patient's natural lens either in the anterior chamber (in front of the iris) or the posterior chamber (between the iris and natural lens). The new lens helps the patient focus better, leaving the natural lens in place allowing the patient to "accommodate," or shift focus between distant and nearby objects. The procedure is reversible.

Clear Lens Replacement (CLR) is usually recommended to patients over 45 who wear bifocals, since it replaces the natural lens with an artificial one.

RK/AK (Radial Keratotomy/Astigmatic Keratotomy)

Lens Implants | Encino CA | West Hills CARK/AK is a procedure in which the surgeon makes micro-incisions in the cornea with a diamond blade. Although less popular now that the excimer laser is available, RK/AK is still very helpful for low levels of nearsightedness and astigmatism. It can be useful for enhancements as well. The main current use for these incisions is to treat astigmatism during cataract surgery. This is often referred to as Limbal Relaxing Incisions (LRIs).

INTACS (Intracorneal Ring) is a non-laser based procedure that can treat low levels of nearsightedness. The plastic ring segments are placed in the peripheral cornea to flatten the center cornea. The major advantage is that the ring segments can be removed if necessary. However, astigmatism and higher amounts of nearsightedness cannot be treated. Also, enhancements are not possible.
