Toric Intraocular Lenses
Thursday, October 15th, 2009
In cataract surgery the cloudy natural lens of the eye is removed and replaced with a perfectly clear intra ocular lens (IOL). There are three types of IOL’s used in modern cataract surgery; monofocal, multifocal and toric. The standard lens we have had for decades is a monofocal IOL. This lens can give good vision at a set distance but won’t correct astigmatism and won’t give both reading and distance vision. A multifocal lens will give good vision for reading and distance without glasses. It does not correct astigmatism so that has to be done separately. I am writing about toric IOL’s.
Until recently we have not been able to correct for astigmatism in the eye without performing a second surgery on the cornea. LASIK, for example, can correct astigmatism. Astigmatism is when the cornea is not dome shaped, like half of a basketball, but steeper on one side and flatter on the other, like half of a football. When an eye has astigmatism it can’t see clearly at any distance without glasses or contacts. This left many people dependent on glasses for near and distance vision after cataract surgery.
A few years ago the Food and Drug Administration approved toric lenses to be placed in the eye at the time of cataract surgery. These toric lenses have astigmatism power built into the lens. Cataract surgery can now correct near sightedness, far sightedness, and astigmatism. Correcting astigmatism with glasses is good, correcting it with contact lenses is better, but correcting astigmatism with a toric lens is the best. The distance vision obtained with the toric lenses is excellent but they don’t give both distance and near vision. That is the only problem with toric IOL’s, patients still need glasses for reading. They are not multifocal (yet!).
A toric IOL is right for you if; you need cataract surgery, you have significant astigmatism, and you don’t mind wearing glasses for reading.

The History of Lens Implants
Friday, September 18th, 2009
Implanting a tiny plastic lens inside the eye is the standard procedure for correcting cataracts and is also used for correcting the vision in people who are nearsighted, farsighted, and have astigmatism. How did the idea of using a plastic lens implant get started ?
In World War II, some British fighter pilots were wounded in their eyes by plastic fragments from their airplane canopy. Harold Ridley, one of the eye surgeons who treated them, and continued to care for them after the war, recognized that this plastic material that remained in the eye was not rejected by the body as a ‘foreign object’. It was just serendipity that the material was a medically pure grade of plastic, and perfectly suited for use as a lens that could be implanted inside the eye.
Ridley performed the first lens implant surgery on November 29, 1949. This radical idea of putting a lens inside the eye was not completely accepted by the ophthalmology profession until 25 years later. Today, lens implant surgery is the most common operation done. Not just the most common eye operation, but the most common operation done in the United States and in the world. Ridley lived to see his truly visionary idea vindicated. He received many international awards and was knighted by Queen Elizabeth II in 2000. (The actor Sean Connery was knighted at the same ceremony.)
At Barnet Dulaney Perkins Eye Center, we have been using lens implants since 1972 – the first in Arizona. We do over 10,000 lens implant procedures each year, making us one of the leading eye surgery centers in the United States.
