A cataract is a clouding of the natural lens of the eye. This clouding distorts the way light enters the eye and ultimately disturbs the clarity of vision. People who have cataracts will first usually complain of needing more light to read and glare from artificial and natural lights (especially in dim situations). The complaints then progress to describing things as hazy or smoky looking.
There are different types of cataracts. The most common type is age-related and is a result of the natural hardening of the lens. Other types are often genetic or a result of previous injury or inflammation. Almost all types can be treated with surgery to remove the cataract and replace it with a lens implant.
Why choose Center for Sight for your cataract surgery?
We believe in treating each patient with a cataract with customized treatment. While the actual cataract may be the same, no two patients are exactly alike in their needs, desires and expectations.
Preoperatively, we work hard to evaluate the severity of the cataract and more importantly, its direct effect on the patient’s vision and their quality of life. This is all part of the examination and discussion of the potential benefits of cataract surgery. This evaluation and discussion is all done with the doctor.
Once the patient and doctor have decided to proceed with surgical removal of the cataract, the discussion turns to optical outcomes after the surgery. During this evaluation, the patient’s desired vision will be discussed. Some people prefer having better near vision and some like better distance vision. These parameters can be decided preoperatively and the advantages and disadvantages of each vision system can be discussed.
It is at this point that the possibility of premium lens implantation is discussed. The crystalens ®, Tecnis® Multifocal, AcrySof ® ReSTOR ®, AcrySof ® Toric are four lenses that we currently use to decrease the need for any glasses after surgery. Dr. Behforouz is one of only a few surgeons who have extensive experience using all of these lenses. It is this experience that allows him to match the patient’s needs, desires and expectations with the best lens implant design and surgical plan. Sometimes, after cataract surgery, there is a need for further correction with a Carmel LASIK procedure. This is often the case if there is corneal astigmatism or residual refractive error after the initial surgery. It is important to remember that premium lens implantation is designed to reduce the need for spectacles.
The next step in the process is the evaluation for the power of the lens implant that is inserted in the eye to replace the cataractous lens. At Center for Sight, a laser based instrument called the IOLmaster is used to measure the length of the eye. This is the single most important step in determining the correct power of the lens implant. Having the correct implant power will give the patient the highest chance of getting the desired optical outcome.
The cataract surgery is performed at an outpatient surgery center. After dilating the patient’s operative eye, the patient is taken to the operating suite where IV sedation is started. The eye is numbed with drops only and the procedure begins. The procedure itself takes about 10 minutes and the patient is escorted to the post-operative area where instructions are given. Topical anesthesia allow for quicker visual recovery from the surgery and stitch-less incision.
The patient is seen one day post-operatively, one week post-operatively, and one month post-operatively.
During these examinations, the eye is checked for adequate healing. There is a requirement to use eye drops following the surgery for a three-week period to prevent infection and inflammation. Approximately one month post-operatively, an examination for any necessary glasses is done.
Generally, the patients are then seen 6 months after the surgery. After this period, the examinations are spaced out to once a year (the recommended frequency of visits for people over the age of 60).
