Archive | Cataract



A cataract is a slow, progressive clouding of the eye's natural lens. It is caused by a change in the proteins of the lens, which make it less translucent. The cataract interferes with light passing through the eye, resulting in blurred or fuzzy vision. People with advanced cataracts often describe their vision as “looking through a piece of wax paper.” A cataract may make nighttime driving difficult due to glare from oncoming car headlights. Cataracts often make reading more difficult. For the majority of cases, surgery is the only cure.


Cataract Surgery


For the majority of cases, surgery is the only cure. Modern cataract surgery is typically performed through a small incision. High-frequency ultrasound, called phacoemulsification, is used to break up the cloudy lens material, and a micro-vacuum removes it from the eye. A clear, artificial implant lens of appropriate power is placed inside the eye to provide focusing power. Today, no-stitch cataract surgery is performed whenever possible.

The Procedure


Before the procedure can begin the pupil is dilated, and the surgical area is prepared using a sterile cleanser. A topical anesthetic is then administered to the surface of the eye. An incision of 2.5 to 3 millimeters in length is then created at the junction of the cornea (the clear front of the eye) and the sclera (the white part of the eye).

Intraocular Lenses

Intraocular Lenses come in a variety of materials and designs. Your surgeon generally chooses a lens made of a material that is best suited to your individual situation. All intraocular lenses used in our practice are coated with UV filters. Some lenses are yellow in color. These lenses are theoretically better at blocking the light rays in the blue spectrum which are thought to be related to the development of macular degeneration in some patients. Some intraocular lenses are designed to be multifocal in certain lighting circumstances, which may enable patients to see both at distance and near without the aid of spectacles.

PRELEX is a term used to describe presbyopic lens exchange with a multifocal intraocular lens. While the application of the technology is new, the surgical techniques employed are proven successful over many years of use.

Your cornea (the outside part of the eye) and the eye’s natural lens (inside your eye) work together to focus light that comes into your eye. The lens, which is flexible when you are younger, becomes increasingly inflexible as you mature, often after you’ve passed the age of forty. Consequently, you have a difficult time focusing on objects. This condition is known as presbyopia.

Intraocular Refractive Surgery

Intraocular Procedures

Most candidates for intraocular refractive surgery have extreme myopia,hyperopia, and/or significant presbyopia. For such patients, laser ablation of corneal tissue may not be the best option. The risk of corneal instability, dry eye, and bothersome visual side effects make excimer therapy suboptimal for high refractive errors. Although cornea-based procedures have dominated the refractive surgery market, newer intraocular techniques are presenting options for select patients seeking independence from glasses and contact lenses.

All intraocular procedures utilize implantation of an artificial lens to ideally focus light. The practice of lens implantation was first developed for cataract surgery. Lens implantation has multiple potential advantages over corneal refractive procedures, including:

Visian ICL: an alternative to LASIK

Implantable Collamer Lens (ICL)


Introducing a solution for patients with high amounts of nearsightedness. The Visian ICL is a revolutionary refractive lens that can correct vision up to 15 diopters of nearsightedness. The ICL procedure has been repeatedly improved through years of studies and continued refinement. This lens is a posterior chamber implant that is situated behind the iris and in front of the natural crystalline lens. It is also known as a Phakic IOL. The surgery is performed on an outpatient basis, which means that a patient has surgery and leaves the same day.

The Procedure

Prior to the surgery, a surgeon will make two microscopic holes in the iris. Your eye will be numbed with a light topical or local anesthetic. Once the eye is numbed the surgeon will make 2 side port incisions and one main temporal incision that is critical to the insertion process. Next the surgeon will insert the ICL through the main temporal incision and place the lens behind the iris and in front of the crystalline lens. This insertion procedure is typically performed one eye at a time. There is very little discomfort and normally no pain associated with the procedure. Some drops or perhaps oral medication may be prescribed and a visit is usually scheduled the day after surgery. Patients will be advised to arrange for someone to drive them to and from surgery.
