It is designed to be readily removed and exchanged through the same incision. These centers offer a full range of customized treatment options, from wavefront-guided LASIK to intraocular lens (IOL) implants.For more than a decade, Dougherty Laser Vision has also been a leader in clinical research, participating in numerous clinical trials on the latest vision correction techniques and technology. Dougherty is one of just 39 surgeons in the world to serve on the editorial board of the Journal of Refractive Surgery – the American Academy of Ophthalmology’s peer-reviewed scientific journal about new developments in refractive surgery.The investigational Tetraflex lens implant procedure takes just minutes, and is essentially identical to standard intraocular lens insertion during cataract surgery.The lens is made from 100% biocompatible material, and is inserted into the eye through a 3-mm or smaller clear corneal incision. About Dougherty Laser Vision Dougherty Laser Vision serves an expansive three county area, with offices in Los Angeles (Larchmont Village), Ventura County (Camarillo) and Santa Barbara.While corneal procedures for presbyopia are still under a serious debate regarding their long term outcomes and success rate, current surgical options mostly include refractive lens exchange by either monofocal IOLs for monovision or multifocal IOLs.However, none of them could achieve a complete restoration of accommodation, and multifocal lenses are frequently associated to visual symptoms that may decrease patient satisfaction.Pseudoaccommodation comprises a group of techniques that can improve near vision on the basis of the use of the cornea or intraocular lenses (IOLs), resulting in an increased depth of field, multifocality or both .Some of these techniques are based on the adequate performance of the ciliary body using part of the physiological accommodative mechanism, but a surgery for the “real” restoration of accommodation has not yet arrived for clinical practice.
This movement is designed to allow the lens to focus on a single point of light, and truly accommodate (i.e., zoom) to see clear vision at all distances.However, the real restoration of accommodation is more complex, and it has been tried by the use of different, so called, “accommodative” pseudophakic intraocular lenses (AIOL).Overall, the reported results with these lenses by independent authors have been modest in relation with the restoration of the accommodative power of the eye and these modest benefits are usually lost with time due to the long term changes in the capsular bag.“What makes the new Tetraflex lens so exciting is its advanced design, which has been developed to restore zooming power in a way that closely replicates the eye’s natural lens,” said Dr. “Results from earlier international studies are very promising, and show that the Tetraflex may provide superior results to the current crop of accommodating IOLs already approved by the FDA.” Earlier generation IOLs attempt to restore reading vision by diverting incoming light in a multifocal fashion, rather than focusing a single point of light at various distances.Using this approach, they try to trick the brain into perceiving clear all-distance vision.Patients who meet the eligibility criteria and participate in the study will receive the Tetraflex lens at no cost.
