Cataract Surgery FAQ

What is a cataract?

A cataract is a condition in which the lens of the eye becomes clouded or opaque. When this occurs, visual disturbances (for example: glare or fuzzy vision) may make daily activities more difficult.View with cataracts

What is cataract surgery?

Cataract Surgery San JoseCataract surgery is the most frequently performed surgical procedure in the world. In traditional cataract surgery, the surgeon uses hand held instruments to manually create a circular opening in the outer shell of the cataract. Next, the surgeon uses instruments to break up and remove the cataract. Finally, the surgeon implants an artificial intraocular lens (IOL) inside the remaining shell to replace the natural lense.In recent years, laser techonology (which is used in procedures like LASIK) has been incorporated into cataract surgery to enhance the precision and accuracy of the procedure. Dr. Pham uses The Catalys Precision Laser System from Optimedica. It is the world’s most sophisticated laser cataract surgery system. The result of years of development and clinical study, Catalys delivers industry-leading precision and a premium experience for patients.

How does laser cataract surgery work?

The Catalys Precision Laser System features a state-of-the-art laser, advanced 3D imaging, sophisticated software, and other unique features that deliver a precise, customized procedure with exceptional patient comfort.Catalys enables surgeons like Dr. Pham to create a perfectly sized, shaped, and centered circular incision to access, break up, and remove the cataract. This precise and accurate incision allows Dr. Pham to place the artificial intraocular lense (IOL) in the exact intended position. Using the Catalys System, the cataract is removed much more easily and very gently. With the help of sophisticated laser pattern scanning technology, Dr. Pham can create grid-like patterns in the cataract to aid in its break-up and removal.

Is laser cataract surgery safe?

Absolutely. Dr. Pham’s Catalys System uses advanced 3D mapping and image-guidance software that ensures that the laser pulses are delivered only to the intended treatment area, protecting the surrounding eye anatomy. In addition, the Catalys laser system allows for gentler and easier cataract removal.With Catalys, each individual treatment is pre-programmed into the system to improve accuracy and reduce the total procedure time. In addition, the Catalys laser system is uniquely designed to maximize patient comfort.

How precise is laser cataract surgery?

Catalys delivers precision that is unmatched in the industry, producing incisions that are accurate within tens of microns. To put this level of accuracy into perspective, the average width of a single human hair is 85 microns. This precision allows Dr. Pham to place the IOL in a patient’s eye with the utmost accuracy.

What is laser refractive surgery?

Refractive surgery encompasses a number of different surgical procedures for the correction of vision disorders. The most common vision disorders are farsightedness, nearsightedness, and astigmatism.Photorefractive Keratectorny (PRK) and Laser Assisted in Situ Keratomileusis (LASIK) are used in the correction of farsightedness, nearsightedness and astigmatism.Recent FDA approved wavefront technology enables the cornea to be precisely and individually sculpted by the laser to the unique shape of the patient’s eye. A common analogy is replacing mass produced clothes with custom tailored clothes. Custom clothes fit better and allow natural freedom of movement because tailored clothes are designed uniquely for the wearer. Wavefront technology enables the laser eye surgeon to custom fit the lasering of the patient’s cornea to the patient’s specific eye shape potentially improving results with fewer side effects.

How does laser refractive surgery work?

If you imagine the eye as a camera, the iris and the pupil work together like the shutter, regulating the amount of light entering the eye. The retina functions as the film and is the surface upon which light must be exactly focused. The retinal image is then transmitted to the brain where the picture the eye received is recognized. The cornea (the very front portion of your eye), combined with the lens, provides the focusing power that controls the clarity and accuracy of the image.Nearsightedness, farsightedness and astigmatism are the result when the cornea is too steep or too flat, or when the eye itself is too long or short. These refractive errors cause the light rays passing through the cornea and the lens to come into focus before or beyond the retina. The result is blurred vision. Refractive procedures of all types are designed to change the shape of the cornea.They improve vision by correcting the refractive error, focusing light rays passing through the lens of the eye more directly on the retina and creating a clearer image. There is no upper age limit for patients considering refractive surgery though they must be at least 18 years old.Patients with moderate or low degrees of myopia are especially suited for refractive surgery. Those with high degrees of myopia can expect a significant reduction in the prescription and thickness of their glasses, and may still need to wear them on a part-time basis. A touch up or enhancement with a second treatment may be advised to obtain the best results.
