Laser Cataract Surgery offers the most precise and predictable visual outcomes available, and our surgeons at Diagnostic Eye Center in Houston are proud to offer this revolutionary technology to our patients. While traditional cataract surgery is a safe and successful procedure, the LenSx® Laser replaces many of the steps previously done by hand, increasing the level of precision during the surgery and allowing our surgeons to achieve better results than ever before.
In addition to Laser Cataract Surgery, advanced technology intraocular implants give our patients throughout the Houston area patients more options for clear vision at all ranges, allowing us to customize your results for your lifestyle. It is an exciting time to have cataract surgery! The doctors and staff at Diagnostic Eye Center are ready to answer all of your questions and will help guide you along this process.
What is a Cataract?
A cataract is a term used to describe clouding of the natural lens inside the eye. In young people, the lens is not only clear, but flexible. The flexibility of the lens allows it to change focus for objects at different distances much like a camera does, meaning that vision at both far and near is sharp. As we enter our 40’s, the lens begins to change. It becomes less and less flexible with every passing year, resulting in the gradual loss of the ability to focus up close over time. It also becomes more cloudy.
Once the lens clouds enough to affect vision, it is called a cataract. This process is a normal and expected part of aging — every single one of us will eventually develop this condition if we live long enough. There is no good medical treatment for cataracts — the only treatment for cataracts is surgical removal and replacement with a clear Intraocular Lens (IOL) implant.
What can I expect during cataract surgery?
At our Houston Clinic, cataract surgery is performed as an outpatient procedure and only takes about ten to fifteen minutes. Patients are given mild oral or IV sedation, and eye drops are used to numb the eye. Our surgeons first use the LenSx femtosecond laser to make small incisions on the front of the eye, to create an opening in the capsule to access the cataract and to correct small amounts of astigmatism. Then in the operating room, the cataract is removed using a procedure called phacoemulsification, which involves an ultrasonic probe that dissolves the cataract. An intraocular lens implant is then placed inside the eye.
Following cataract surgery, patients use antibiotic and anti-inflammatory drops for about four weeks. Strenuous activity should be avoided for one week, but most patients return to a desk job the day after surgery. As with any surgery, complications and side-effects can occur. Fortunately, the rate of complications from modern cataract surgery is very low. Your surgeon will discuss possible complications and side effects with you at the time of your consultation.
What are the benefits of Laser Cataract Surgery?
Astigmatism Correction. In an eye that has astigmatism, the vision is blurred because the cornea (front surface of the eye) is shaped more like a football than a basketball. The LenSx laser can reduce small amounts of astigmatism by reshaping the cornea, resulting in better vision without glasses.
More Precise and Customized Corneal Incisions. In traditional cataract surgery, the surgeon makes tiny incisions on the front of the eye with a small blade. Using the innovative technology of the LenSx Laser to make these incisions provides greater precision and control.
Better Intraocular Lens Placement. One of the greatest capabilities of the LenSx Laser is its pristine and reproducible capsulorhexis formation, which creates an opening in the lens capsule to allow access to the cataract. The laser makes this opening as a perfect circle with the exact same size and position every single time. This allows more precise placement of the intraocular lens and ultimately more predictable visual outcomes.
Automated Cataract Fragmentation and Easier Removal. The laser fragments the cataract into pieces and softens it. You can think of it like putting a cookie in the microwave for a few seconds or dipping it in milk, making it soft and crumbly. This makes removal faster and easier.
Faster Recovery Times. Because the LenSx Laser fragments and softens the lens, less ultrasound energy is needed to remove it. This results in less swelling and faster visual recovery.
What is the ORA System™?
The ORA System can be used for all cataract surgery patients, but it is especially beneficial for patients who have undergone previous refractive surgery, such as LASIK, PRK, or RK. These patients have altered corneal curvatures, which have traditionally caused challenges when calculating the power of the intraocular lens to be placed inside the eye.
By using the ORA System, our cataract surgeons can now take multiple instantaneous measurements to ensure proper lens selection.The benefits of the ORA System include:
- Increased accuracy of lens power selection
- More precise astigmatism correction
- Improved visual outcomes
CUSTOMIZED INTRAOCULAR LENS OPTIONS
Intraocular lens (IOL) technology is continuously advancing, which means that our surgeons can offer a more customized surgical plan to give you the best visual results for your lifestyle. Every patient is different, and our doctors will take the time to understand your unique visual needs and help you choose the best intraocular lens for your eyes.
Dr. Marc Sanders and Dr. Andrew Salem, along with our team of ophthalmologists in Houston will discuss your cataract surgery options with you. If you are motivated to reduce your dependence on glasses and contacts, ask your surgeon if you are a candidate for an advanced technology IOL.
