About Cataract Surgery

The Nielsen Eye Center is proud to announce New All Laser Cataract Surgery! Alcon’s advanced LenSx® laser offers a precision based solution for your eyes. This bladeless, computer controlled laser surgery is planned and performed to exacting, individualized specifications not attainable with other surgical methods. The Nielsen Eye Center is one of the first eye care facilities in the Boston area to offer this state-of-the-art laser treatment.

Cataracts are one of the most common eye conditions affecting Americans over the age of 40. The LenSx® Femtosecond Laser is the first bladeless cataract surgery developed. While all human eyes share the same basic anatomical structure, each eye has a different size, depth, curvature of cornea and other key features, which is why every eye must be carefully measured and mapped prior to cataract surgery. While these measurements are routinely performed prior to any eye surgery, the LenSx® laser uses even more advanced technologies to capture incredibly precise, high definition images of your eyes. These images and measurements provide data that is then used to plan and perform a very precise procedure not otherwise attainable with traditional surgery. After these measurements are obtained, Dr. Nielsen guides the LenSx® Laser over the area of the cataract and gently makes small, corneal incisions or anterior capsulotomies. The cataract is then removed and a lens implanted. Since the LenSx® Femtosecond Laser is designed only to remove cataracts, not to improve vision after cataract removal, refractive lens implants can provide significant improvement of your vision once cataract surgery is complete. With many lens options available, Dr. Nielsen and Dr. Moreira will help determine which lens type is right for you.

About Cataract Surgery

On the day of cataract surgery, you will arrive at the Surgery Center in Dedham about an hour prior to your surgery time. Our well trained nurses greet you and prepare you for IV sedation. We make sure that you are comfortable and relaxed before we move into the operating room. You will then be taken into the surgery suite where both dilating and anesthetic drops will be administered to minimize any discomfort during the operation.

The Procedure

During cataract surgery, you lie on your back and look at a bright light. Most of our patients do not feel discomfort or even remember very much about cataract surgery. Cataract surgery is an outpatient procedure that will only take about 10 minutes. During cataract surgery, the cataract is removed with an advanced technique called phaco-emulsification, or small-incision cataract surgery. A tiny incision is made in the front part of the eye. The cataract is then broken into microscopic particles using high energy sound waves and gently suctioned from the eye. Then, to compensate for the removal of the eye’s natural lens, an intra-ocular lens (IOL) is implanted into the eye. The small incision does not need stitches and remains tightly sealed due to the eye’s natural pressure.


Treatment Options

Cataract surgery is the most common surgical procedure in the United States. Advancements in technology have led to the development of all-laser cataract surgery.

ALL-LASER CATARACT SURGERY

Unlike traditional cataract surgery, all-laser cataract surgery is bladeless. Dr. Nielsen uses a laser to create the access incision. The laser is also used to break up the affected lens, which optimizes reproducibility – in other words, the surgeon is able to make the same exact incision each time. Another advantage of all-laser surgery is that it provides Dr. Nielsen with real-time, three-dimensional imaging, allowing for true customization of the lens replacement procedure.

TRADITIONAL CATARACT SURGERY

In traditional cataract surgery, Dr. Nielsen uses hand-held instruments and blades to remove your cataract, and put in its place a basic fixed-focus lens implant to correct your vision. With basic cataract surgery, you will see clearest far away, but less clear at mid-range and blurry for near. Basic lens implants do not correct astigmatism. If you have astigmatism, which means that the front part of the eye is shaped more like the back of a spoon rather than round like a ping pong ball, then you would most likely end up in bifocals after surgery for best corrected vision. Individuals who choose basic cataract surgery usually see fairly well far away without glasses. In order for your eye to see all three zones, you will need glasses. Should you opt for basic cataract surgery, you will most likely still need glasses to read, or bifocals for best vision.

Recovery from Cataract Surgery

Cataract surgery is done on an outpatient basis, and patients are able to return home the very same day. An eye patch is worn at night for a week and patients are advised to avoid heavy lifting for a week. Patients begin postoperative eye drops to avoid inflammation or infection. According to a survey conducted by the American Society of Cataract and Refractive Surgery, more than 98% of cataract patients had their vision successfully improved after cataract surgery. Many patients experience vision that is actually better than before they developed cataracts.
