Laser Cataract Surgery


A Cataract is a clouding of the natural lens inside the eye. This lens, located behind the Iris, works just like the lens of a camera. It focuses light images on the retina, which sends images to the brain. The human lens can become so clouded, it keeps light and images from reaching the retina.

A cataract can be the reason sharp images become blurred, bright colors become dull, or seeing at night is more difficult. It may also be the reason reading glasses or bifocals, that used to help with reading, or simple tasks no longer seem effective. Vision with cataracts has been described as seeing life through old, cloudy film. But, a cataract is not a “film” over the eyes. It cannot be prevented, and changes in diet will not make it go away. Eye injury, certain diseases, or even some medications can cause the clouding.

The best way to treat a cataract is with surgery that removes the old, clouded lens and replaces it with a new, artificial lens to restore your vision, and significantly improve your quality of life. Modern technology has made both the surgery, and the replacement lenses safer, and more effective. For instance, the refractive cataract laser has significantly increased surgical precision. And, unlike traditional replacement lenses that only worked for distance, multifocal lenses allow patients to see better at all distances. Near, far, and in-between, are all crystal clear without glasses.


Great leaps in medical technology make cataract surgery one of the safest, and most successful procedures. Cataract surgery is generally a simple, outpatient procedure with little discomfort, requiring only a few hours, and a topical anesthetic. The goal of the operation is to break the old, cloudy lens into pieces, remove the pieces from the eye, and insert a lens to replace the natural lens. Traditionally, the surgeon would make a tiny incision in the eye with an instrument about the size of a pen tip. Now, patients also have the option of choosing a bladeless, computer-controlled refractive cataract laser to perform several of the most critical steps of cataract surgery to avoid any human error.


The CATALYS® Precision Laser System is indicated for use in patients undergoing cataract surgery for removal of the crystalline lens. Intended uses in cataract surgery include anterior capsulotomy, phacofragmentation, and the creation of single plane and multi-plane arc cuts/incisions in the cornea, each of which may be performed either individually or consecutively during the same procedure.

Femtosecond laser assisted cataract surgery offers a reproducible, noninvasive technique to replace the least predictable and most technically demanding steps of conventional cataract procedures.

Ocular Refractive Lenses

There are four different types of refractive errors: Myopia, or nearsightedness; Hyperopia, or farsightedness; Astigmatism, or steeper meridians in a cornea; and Prebyopia, an age-related decline in eyesight. While glasses and contact lenses can correct refractive errors, there is a more permanent solution. Ocular refractive lenses are a new technology that may be more effective to correct astigmatism as well as reading vision, than the traditional single vision lenses that are typically used in cataract surgery. A Refractive Lens is an intraocular lens that is placed in the eye to correct refractive errors. However, this procedure is only recommended for patients who have a Cataract and need Cataract surgery to restore there vision. If you have a refractive error, consult Dr. Garrana to see if Refractive Lenses would work for you.
