A cataract is an opacity that clouds the natural lens inside the eye. Normally the path of light to the retina (where the light sensors are) is as clear as possible. When proteins that make up the lens clump together, the resulting cataract blocks some of the light, making vision blurry or hazy.
Cataracts typically occur more frequently in the aging population, however there are many other factors such as family history, diabetes, long term UV exposure, or certain medications like steroids that can cause cataracts. Also, previous eye injuries can be an attributing factor.
Cataract symptoms may include:
Some people actually experience an improvement in their near vision during the beginning stages of a cataract. Unfortunately, this effect goes away as the disease progresses. Early on, a cataract may be treated with increased glasses or contact prescription. Once the cataract begins to interfere with daily tasks such as reading and driving, surgery is the only remaining option.
Cataract Surgery
Cataract surgery is a frequently performed and highly successful procedure. It is an outpatient procedure usually taking less than 20 minutes to complete.
During the surgery, Dr. Yoon removes the cloudy natural lens from the eye while the patient is under a topical anesthesia. Next, Dr. Yoon inserts an intraocular lens (IOL), which remains permanently in place of the removed natural lens. The IOL compensates for the magnification the old lens provided. Modern IOLs are designed for various functions and made out of different materials; your doctor will know which is most appropriate for your individual case. After the operation, Dr. Yoon will apply a shield for the eye and provide you with eye drops to use as directed.
Near Vision Correction with Cataract Surgery: Freedom from reading glasses and bifocals
Patients now have the option of choosing a multifocal or accommodating lens implant during cataract surgery. These implants allow you to see up close as well as distance without the help of bifocals or reading glasses. It corrects the process of "presbyopia" which is the gradual loss of focusing ability that happens after the age of 40. Most patients will be able to read, sew, drive, and play golf without the need for eyeglasses; adding convenience and freedom to their lives. These "presbyopia" correcting implants are generally not covered by insurance and usually require additional out of pocket expense. Dr. Yoon will discuss with you if you are a candidate for this type of implant.
Recovery from Cataract Surgery
The patient may return home shortly after the procedure. With proper rest and avoidance of any strenuous activities such as heavy lifting, recovery is usually a matter of days, with only minor discomfort. A few follow up appointments will be required to ensure the eye is healing properly and initial results are sustained.
