Best options for cataract surgery in Louisville

June is Cataract Awareness Month, so now is a good time to present your options clearly explained.

Intraocular lenses, or IOLs, are implantable devices that replace the natural lens in the human eye, typically after the natural lens has developed cataracts. Cataracts are an irreversible progressive condition that diminishes vision quality.
When cataract surgery is performed the natural lens you were born with is removed.  The new lens we replace it with will determine how you see and what you clearly see. If we use standard Intraocular lenses, the ones that Medicare and many insurance companies pay for, you will have three options:

David W. Karp, MD, F.A.C.S. 
  • Distance option - Both lenses give you distant vision only
  • Close-up option - Both lenses give you close up vision only
  • Mono-vision - One lens gives you close up vision/one lens gives you distance vision.
Premium intraocular lenses, on the other hand, can allow you to see near, mid distance and far distance.

The premium IOL we recommend is the AcrySof® ReSTOR® lens. It was designed to provide quality near, mid-range and distance vision by combining the strengths of what are know as apodized diffractive and refractive technologies. That may sound confusing so let's try to simplify those terms because that apodization is what makes these lenses so special and effective.

First, please understand that similar technology has been used for years in microscopes and telescopes to improve image quality, and has now been patented for use in intraocular lenses by Alcon.

Apodization is the gradual tapering of the diffractive steps from the center to the outside edge of a lens to create a smooth transition of light between the distance, intermediate and near focal points. Diffraction involves the bending or spreading of light to multiple focal points as it passes through the lens. On the AcrySof® ReSTOR® IOL, the center of the lens surface consists of an apodized diffractive optic. This means that the series of tiny steps in that center area work together to focus light for near through distance vision.

Basically, that's about it. It takes more than just bending light to make a multifocal intraocular lens effective and efficient. The lens also has to let in as much light as possible where it is needed and that is precisely what apodization does. Simply put, that's what makes the AcrySof®ReSTOR® IOL the best of its kind on the market today.

If you want to see the best you can possible see with the one and only pair of eyes you have, then we recommend the  AcrySof® ReSTOR® lenses as your smartest option.

How Glaucoma Eye Drops Can Grow Eyelashes

Glaucoma is a disorder of the eye in which patients can lose vision due to gradual optic nerve deterioration. The way ophthalmologists treat this is by lowering the eye pressure or intraocular pressure (IOP).

Over the past decade, the most commonly used class of eyedrops for glaucoma has been the daily-use prostaglandin analogues. The currently available medicines are latanoprost (name brand Xalatan and its generic equivalents), bimatoprost (Lumigan), travoprost (Travatan), and most recently tafluprost (Zioptan). These work on a cellular level to reduce production of fluid within the eye and increase the outflow, thereby lowering the IOP. All of these have been found to have some minor side effects, including eyelid darkening, eye redness which is often temporary, iris darkening, eye irritation and eyelash growth. Women who use these drops are often pleased by the thicker, fuller eyelashes that can result. The makers of Lumigan have created the product Latisse, which is basically the same medication packaged with a brush for placement on the eyelid skin near the lashes.

In 2008, Latisse was approved by the FDA for the treatment for eyelash hypotrichosis, meaning inadequate, sparse or insufficient eyelashes. This condition can occur as eyelashes are pulled off from repeated wearing of false eyelashes or simply breaking off. When Latisse is applied once daily to the base of the eyelashes, growth of lashes can be seen within 8 to 16 weeks, which represents the hair cycle of the eyelash.

Daily use of these glaucoma medicines has a similar effect on eyelashes; in fact, this is how it was discovered. Other adverse side-effects include eye inflammation, swelling in the retina which could affect vision, and darkening of the iris, which is not reversible. These occur very rarely, whereas eyelash growth is so common, it is expected. So here is a circumstance where one “side effect” or “adverse reaction” has yielded positive results for many women seeking to grow longer and thicker eyelashes.
