This creates a thermodynamically unstable diffusion gradient, which is corrected over 12 to 15 hours as macromers diffuse toward the irradiated region to once again establish uniform concentration throughout the matrix. The LAL is the only IOL available that allows for post-operative refractive adjustment and is currently available in Europe, Canada and Mexico, while it is still undergoing clinical trials in the US. The same group at the University of Utah performed a retina safety study16 in a rabbit model in which they performed phacoemulsification with implantation of the LAL in one eye and a silicone lens with no UV filter in the other eye (to serve as control). Intracameral Lens (ICL) or phakic IOL: While not a lens replacement, intracameral lenses also offer a permanent vision correction by way of an artificial lens implant.

The past three decades has seen a spirited, noble race to intraocular lens perfection. The Light Adjustable Lens (RxSight) is different from prior IOLs, as the power of the lens can be changed after implantation. They jointly developed a lens whose three dimensional structure could be altered non-invasively with the application of light energy. The Light Adjustable Lens is a unique IOL that offers patients truly customized vision after theyve had cataract surgery. There are mainly two potential shortcomings with this technology, the first one is the number of post-operative visits required for the adjustment and lock-in procedures, something that can be managed by a standardised protocol for the post-operative visits and trained staff, since the LDD treatment itself takes usually under two minutes. "In fact, a Swedish study 6 using national data showed that we reach desired refraction in only around 50% of patients," said Dr. Schultz. Offering unprecedented versatility and control, these lenses have revolutionized vision correction.

The adjustment occurs when all non-attached solutes equally distribute themselves throughout the optic after irradiation with ultraviolet light that causes the photosensitive macromers to polymerise in the irradiated region. As Light Adjustable Lenses are designed to react to UV light during the adjustment process, exposure can cause unintended vision changes that make it difficult to properly adjust the LAL with light treatments. The research can speak for itself. Jin GJ, Crandall AS, Jones JJ, Intraocular lens exchange due to incorrect lens power.

In fact, in a study which was conducted by the FDA involving a total of 600 subjects, those subjects with LAL implanted in their eyes were twice as likely to achieve 20/20 vision without requiring glasses, as opposed to those subjects which received a normal monofocal IOL. Dr. Chang added that the EUREQUO study reported refractive results from more than 280,000 patients from 100 clinics. Toric IOLs accommodate the abnormal, football-like shape of the eye caused by astigmatism. Intake of medications that increase the sensitivity to ultraviolet (UV) light, Intake of retino-toxic medications (example: Tamoxifen). Light Output angle easily adjustable Soft edged light easy to blend with other lights More expensive models have a very even field of light distribution. If you have astigmatism and want the most out of cataract surgery, the Light Adjustable Lens may be the right IOL for you! In such a situation, the next best option is to have a corneal-based refractive surgery, such as LASIK, after cataract surgery. Fam HB, Lim KL, A comparative analysis of intraocular lens power calculation methods after myopic excimer laser surgery. With this method, the natural lens stays in place and the lens is inserted to rest in the space between the iris and the lens. The Vivity lens is mainly a distance lens with good intermediate and possibly some reading. The lens prescription can be adjusted after it's implanted in the eye by exposing it to UV light. Olson R, Mamalis N, Haugen B, A light adjustable lens with injectable optics. If you pick this lens, you won't need to undergo LASIK or any other laser vision correction surgery.
