Cataract Lens Implants

Educational articles about the benefits and health issues associated with cataract lens implants from the doctors of Ophthalmology at Fort Lauderdale Eye Institute.

Clear Lens Extraction

Clear lens extraction (CLE or CLEAR) is the process of removing a non cataractous natural lens of the eye with intraocular lens placement as a refractive procedure; and is also known as RLE (refractive lens exchange).

CLE has been around for decades and is the same procedure used to remove cataracts except there is no cataract present therefore the lens is clear versus cloudy.  CLE is usually performed on those who no longer wish to wear glasses or contact lenses; and patients over 40 years of age that are considered less than ideal candidates for LASIK.  Other indications for clear lens extraction include correction of vision loss due to mild cataracts, hyperopia (farsightedness), and patients with high myopia that is not easily managed by other refractive procedures.  Your ophthalmologist will be able to tell you whether or not CLE is […]

Premium Intraocular Lenses

If you are having cataract surgery, your cataract surgeon will replace your clouded lens with a clear artificial lens.  There are several different types of premium intraocular lenses:

Aspheric Lens Implants

Specifically designed to reduce the visual disturbances caused by the optical aberrations found in ordinary lens implants, aspheric lens implants reduce the tendency to see “glare”. Aspheric lens implants are primarily used to correct distance vision and reading glasses will still be needed following cataract surgery.

Toric Lens Implants

As discussed in a previous article, toric lens implants are a type of intraocular lens implant that provide a safe and predictable alternative to reduce or eliminate refractive astigmatism following cataract surgery.

Near Vision Presbyopia Correcting Multifocal Lens Implants

Near vision presbyopia correction premium intraocular lenses may result in excellent vision at both distance, intermediate, and near and may entirely eliminate the need for glasses. Types […]

Cataract Lens Implants – Premium vs Standard Lenses

A cataract, otherwise known as a “crystalline lens,” is a clouding of the natural lens of the eye. Cataracts are usually found in middle-aged to older people and can be a normal part of the ageing process. When a cataract becomes too cloudy it will make it difficult for that person to see and cataract surgery will need to be performed. Not to worry though, cataract removal is one of the most common surgical procedures in the United States and it is estimated that nearly 3 million operations are performed annually.

The actual surgical procedure to remove cataracts involves removal of the cataract lens and inserting an artificial lens (cataract lens implant) as a replacement to restore vision. This artificial lens is also known as an IOL or intraocular lens. Cataract removal is typically done under local anesthesia, it is […]

Advanced Technology Implants for Cataract Patients

There are many factors that can cause a patient to develop cataracts, a condition where the lens, found behind the iris and the pupil, becomes clouded: aging, eye trauma, excessive sun exposure, disease inside the eye, family history, smoking, diabetes, and poor nutrition. No matter the underlying cause, it is important to have the clouded natural lenses removed and replaced with new implanted artificial lenses.
Cataracts most commonly develop in people over the age of sixty. People often don’t realize they have cataracts as their vision deteriorates very slowly and, over time, they don’t notice the changes. But at a certain point, the clouding begins to really impact the vision. This is the time to have your cataracts removed.
Lens choices for cataract replacement
Surgery is the only way to remove a cataract. The clouded lens will be replaced with an […]

The Fascinating History Behind the Intraocular Lens

In 1946, Dr. Harold Ridley of London, was removing a cataract from a patient. A medical student was observing. After surgery, the student asked Dr. Ridley: “You took out the cataract, but you did not replace it with anything. Why not?”. Dr. Ridley patiently explained that that was not the way things were done. But that got him thinking. He had cared for many injured RAF pilots during the war. It was not unusual for him to see a pilot with a fragment of a shattered cockpit inside the pilot’s eye. Surprisingly, this fragment was usually well-tolerated for lengthy periods. Why, he thought, could we not make an intraocular lens out of this plastic material and implant it at the time of surgery? The material was polymethyl methacrylate, which is also known as Plexiglas, Lucite and Perspex. Ridley’s early attempts were usually unsuccessful.
