Artificial lenses (IOLs) are implanted in the eye to replace natural lenses that have been damaged by cloudy cataracts or even presbyopia. The IOL procedure to replace a patient’s natural lens with a multifocal lens is the same procedure used in cataract surgery. Until recently, IOLs were only available to correct distance vision. These monofocal lenses helped improve distance vision after cataract surgery, but patient still needed glasses or contact lenses for near vision activities like reading or playing cards. Now, advancements in technology have produced a new multifocal IOL, which allows patients to see clearly at all distances—near, far and many distances in between. Multifocal IOL lenses such as the ReStor and the ReZoom™ preserve distance vision and also correct presbyopia, so many cataract surgery patients—and patients seeking treatment for presbyopia alone—can enjoy clear sight without relying on glasses.

 Using apodization, diffraction and refraction technologies, the ReSTOR lens improves upon ordinary, monofocal replacement lenses, by providing comprehensive focusing capabilities so the patient can see clearly in a range of lighting conditions and at all distances—at noon or midnight, nearby or far away, and many distances in between.
Up to 80% of those patients who use the ReSTOR lens don’t need to rely on glasses or contact lenses after surgery.
The ReZoom™ multifocal IOL helps patients focus clearly on objects at a range of distances and in varied light conditions. Featuring a patented lens design called Balanced View Optics Technology, the ReZoom™ lens has five spherical segments with smooth transitions in between so the eyes focus seamlessly from one distance to the next.
The center of the lens is optimized for bright light and distance vision, while the fourth zone supports near-vision in a variety of light conditions. the outermost zone will accommodate for low-light distance vision (such as when driving at night). The ReZoom™ lens is also specially designed to reduce internal reflections and minimize glare.
 Surgeons at the Mount Ogden Eye Center and our multifocal lens counselors can help patients decide which new lens technology would be best for their lifestyle and activities.
If you have been diagnosed as having cataracts and are experiencing one or more of the following vision problems, you may be a candidate for the ReZoom™ multifocal IOL:
- Difficulty reading
- Difficulty seeing close-in objects
- Difficulty in driving, especially at night
- Frequent changes in glasses prescription
- Need for bifocals
Blepharoplasty can rejuvenate puffy, sagging or tired-looking eyes by removing excess fat, skin and muscle from the upper and lower eyelids. It may be performed for cosmetic reasons or to improve sight by lifting droopy eyelids out of the patient's field of vision. Blepharoplasty can be combined with BOTOX® treatments to raise the eyebrows or reduce the appearance of wrinkles, crow's feet or dark circles under the eyes.
The retina is a thin sheet of nerve tissue in the back of the eye where light rays are focused and transmitted to the brain. The vitreous is a gel-like substance that fills the eye and is connected to the retina, optical nerve and many blood vessels. Problems with the retina and vitreous---including retinal tear and detachment, macular degeneration, diabetic retinopathy , infection and trauma---can lead to vision loss and blindness. Early detection and treatment are critical in correcting problems before vision is lost or preventing further deterioration from occurring.
As mentioned earlier, the vitreous is a clear liquid that fills our eyes and gives them shape. When we are young, the vitreous has a thick, gelatinous consistency and is firmly attached to the retina, at the back of the eye. As we age, however, the vitreous thins and separates from the retina. Although this usually results in nothing more than a few harmless floaters, tension from the detached vitreous can sometimes tear the retina.
If liquid were to penetrate the torn area and collect behind the retina, or between the nerve layers, the retinal tear can potentially progress to a retinal detachment. Retinal detachment can cause significant, permanent vision loss and requires immediate medical treatment.
Specifically there are three types of retinal detachment. The most common detachment will occur when fluid leaks into the retinal area. Those individuals who are nearsighted or who have had a recent eye injury or eye surgery are most susceptible. A second type of detachment can occur, although less frequently, when friction between the retina and vitreous or scar tissue pulls loose from the retina, something, which occurs most often in patients who have diabetes. The third type of retinal detachment is a disease-related swelling or bleeding under the retina, which can push the retina away from the eye wall.
Indications of retinal tear or detachment may include flashes of light, a group or web of floaters, wavy or watery vision, a sense that there is a veil or curtain obstructing vision, or a sudden drop in the patient’s quality of vision. If you experience any of these symptoms, call your doctor immediately. Early treatment is essential to prevent potential loss of vision.

Diabetic retinopathy is a complication of diabetes that weakens the blood vessels that supply nourishment to the retina (the light-sensitive lining in the back of the eye where vision is focused). When these weak vessels leak, swell or develop thin branches, vision loss occurs. Laser surgery is the treatment of choice.
Focal laser coagulation may be recommended for patients with clinically significant macular edema (CSME) – swelling of the central retina, called the macula. The laser coagulates, or dries up, the fluid that is causing the swelling. A similar procedure called scatter laser photocoagulation (also known as pan-retinal photocoagulation or PRP) destroys abnormal blood vessel growth in patients with proliferative diabetic retinopathy (PDR). If there is blood in the eye obscuring the laser, a vitrectomy (Vitreoretinal surgery) may be performed to drain the blood in preparation for photocoagulation.
Fortunately, diabetic retinopathy is preventable. People with diabetes are most susceptible to developing it, but your risk is reduced if you follow your prescribed diet and medications, exercise regularly, control your blood pressure, and avoid alcohol and cigarettes. Regular eye exams are an integral part of making sure your eyes are healthy.
Although damage caused by diabetic retinopathy cannot be corrected, patients diagnosed with the condition can be treated to slow its progression and prevent further vision loss.
Treatment modalities include laser and surgical procedures:
- Laser surgery
- Vitreoretinal surgery
- Medications
The macula is a part of the retina in the back of the eye that ensures that our central vision is clear and sharp. Macular degeneration causes a progressive loss of vision. It is the number one cause of blindness in the U.S.
There are two kinds of macular degeneration: "wet" and "dry." The "wet" form can be treated in its early stages. Regular eye exams are highly recommended to detect macular degeneration early and prevent permanent vision loss.
Symptoms often associated with macular degeneration include:
- A gradual loss of ability to see objects clearly
- A gradual loss of color vision
- Distorted vision
- A dark or empty area appearing in the center of vision
