Cataract is a common but treatable cause of visual loss where the natural lens of the eye becomes clouded. Cataracts can be caused by injury, certain medications, illness (such as diabetes), prolonged exposure to ultraviolet, and smoking. Millions of people including more than half of Americans over the age of 65 are affected by cataracts. Vision in patients with early cataract can often be improved with a change in eye glass prescription, though, as the cataract progresses, cataract surgery in the only option for visual rehabilitation.
Symptoms of Cataract
- Blurry or hazy vision
- Double Vision
- Sensitivity to glare
- Frequent changes in eyeglasses prescription
- Poor night time vision
- Vision that has a yellow tinge
Cataract surgery is a minimally invasive procedure that is typically performed on an out- patient basis using local anesthesia. Cataract surgery replaces the cloudy natural lens of the eye with a clear artificial lens known as an intraocular lens (IOL). Dr. Greco performs small- incision cataract surgery called phacoemulsification, also known as phaco surgery. Through small incisions in the eye, special instruments are used to deliver ultrasound power to break up the crystalline lens and remove it from the eye. Usually, an acrylic or silicone lens is then inserted in the eye to replace the cataract. This leaves the eye with a normal power at the end of the surgery. Because of its small size, the incision usually does not require a stitch.
A wide range of lens implants are available to cataract patients each offering different advantages for post surgery vision. The most effective lens to use depends upon the patient’s individual preferences and goals for their vision. The Premium IOLs reduce the need for glasses or contacts after cataract surgery.
Crystalens® is the only FDA approved accommodating intraocular lens. Accommodation is the ability to shift focus between near by and distance objects. Crystalens® is made with flexible silicon that has hinges on each side allowing it to change position in the eye slightly to adjust focus at different distances. This lens gives excellent distance and intermediate vision and good near vision. More than 200,000 crystaLenses have been implanted worldwide.
Acrysof® IQ ReSTOR® IOL is a multifocal intraocular lens that provides excellent distance and near vision and good intermediate vision.
Benefits of the ReSTOR® IOL
The Acrysoft® ReSTOR® IOL is the only IOL with patented apodized diffractive technology. Apodized diffraction provides the patient with an increased depth of focus.
- Unlike other IOLs that are made of silicone or hard plastic, the Acrysof® IQ ReSTOR® IOl is a soft, foldable acrylic lens.
- There is no need for stitches because a smaller incision is made in the eye.
- The ReSTOR® IOL corrects for both cataracts and presbyopia.
- The implant filters blue light without affecting the quality of vision.
Acrysof® IQ Toric
Toric IOLs are able to correct varying degrees of astigmatism in patient undergoing cataract surgery. If you have astigmatism and cataract, Dr. Greco may recommend the Acrysof® IQ Toric lens.
Yag Laser Posterior Capsulotomy is laser surgery to correct the most common after affect of cataract surgery called posterior capsular opacification or PCO. When PCO occurs, the patient experiences a recurrence of the visual difficulties that precipitated the original cataract surgery. During cataract surgery, the clouded lens in the eye is removed from the capsule and is replaced with a clear artificial lens called an intraocular lens or IOL. Weeks, months, and even years after the surgery, some patients may again experience diminished or abnormal vision. This may result if the lens capsule has become cloudy or wrinkled. When visual difficulties become too intrusive in daily life, a Yag Laser Posterior Capsulotomy can be performed on a outpatient basis to restore vision.
