One of the best options for the treatment of cataracts is the implantation of intraocular lenses, or IOLs. Replacing natural lenses with artificial lenses allows for improved vision and often for decreased reliance on glasses or contact lenses. At Washington Eye Physicians & Surgeons, Howard S. Weiss, MD, provides quality cataract care to his patients. With more than 20 years of experience, Howard S. Weiss, MD, is highly familiar with a variety of astigmatic and multifocal lens implants for cataract treatments, including Restor, Tecnis, Crystalens, and Rezoom.

Unlike standard intraocular lenses, multifocal lens implants provide the ability to see at different distances, reducing dependence on glasses after cataract surgery for many patients. These artificial lens implants are similar to the natural lens in the eye and allow for a more normal range of vision for activities like driving, reading, and working on a computer. Many patients who have multifocal lens implants find they are dramatically freed from glasses after surgery, and some no longer need to wear glasses at all.

Like a standard intraocular lens implant, a multifocal intraocular lens implant fits into the eye in the same space as the natural lens. These FDA-approved implants can be used in surgeries performed by either conventional techniques or with femto-second laser-assisted techniques to reduce astigmatism.

Practicing in the suburban DC offices of Washington Eye Physicians & Surgeons, Howard S. Weiss, MD, specializes in eye surgery and laser treatment. Howard S. Weiss, MD, has improved the vision of many patients through bladeless femtosecond laser-assisted cataract surgery.

Bladeless femtosecond laser-assisted cataract surgery allows an ophthalmologist to customize each procedure based on the anatomy of the patient’s eye. Because this surgery is performed with a laser, the many steps previously done by hand are eliminated. The procedure is completed in minutes, with an extraordinary level of precision.

The LenSx femtosecond laser system used during the surgery provides a real-time video image of the eye, enabling Dr. Weiss to make an exact bladeless incision according to the dimensions of the patient’s eye. This accurate technology also fragments the cataract to facilitate removal and allows for precise centration of the new intraocular lens.

On the day of the surgery, the patient receives a mild sedative to help him or her to relax. Medical personnel then cleanse and drape the eye area. After the procedure, the patient is fitted with a clear eye shield that allows immediate vision. Most patients return to their normal activities within one or two days. Follow-up medical visits typically are scheduled for the first and third weeks after the procedure.

Howard S. Weiss, MD has more than 20 years of experience as a prominent cataract surgeon. Howard S. Weiss, MD practices in Washington, DC and is an expert in astigmatic and multifocal lens implants.

Astigmatic and multifocal lens implants help patients reduce their dependence on eyeglasses after cataract surgery. With these lens implants, patients can usually enjoy activities such as driving, reading, and/or watching television without glasses.

The success of astigmatic and multifocal lens implants varies for each patient, and some implant recipients still need to use eyeglasses for certain activities. Some may choose to have laser vision correction to get additional improvement. Most patients who have multifocal lens implants are happy with the process and the result.

Howard S. Weiss, MD, is a skilled cataract surgeon with thousands of procedures to his credit. An expert on glaucoma and cataracts, Howard S. Weiss, MD, has taught his fellow ophthalmologists through the American Academy of Ophthalmology and teaches eye doctors at Georgetown University and Walter Reed National Military Medical Center.

Aging is often considered the cause of cataracts, but new findings are beginning to uncover the biology behind the disease. Researchers have been considering oxygen-free radicals, which are suspected to play a role in the development of cataracts. Researchers first began focusing on these particles because of their correlation with changes in the body.

Oxygen-free radicals, also known as oxidants, can be produced in superfluous amounts due to toxins, smoke, ultraviolet radiation, and infections entering the body. An excessive amount of oxygen-free radicals can create harmful changes to nearly any cell in the body. The development of cataracts is one of the changes that can occur. Scientists believe the abundance of oxidants, coupled with a deficiency in glutathione, causes the cataract to form. Glutathione is an important antioxidant that can limit the impact of oxygen-free radicals. The theory is, as we age, glutathione in the eye decreases, making the eye susceptible to oxidation.
