Cataracts refer to the clouding of the native lens of the human eye. This occurs with aging, and may present earlier in some individuals such as diabetics and patients on long-term steroid use.
Patients most commonly experience slowly progressive, painless blurring of vision. One eye may also be more affected than the other.
Risk factors include:
Early Cataracts are managed conservatively, and patients are usually prescribed glasses to aid their vision. When Cataracts affect one’s vision significantly, or in the case of those with other eye problems, Cataracts are managed by the surgical removal of the lens (Cataract extraction surgery).
As Cataract surgery is normally done as a day surgery procedure, patients are usually discharged on the same day, a few hours after surgery. They would be started on an eye drop and reviewed in the clinic one day, one week, and one month after the operation. Patients who undergo ECCE may require suture removal one to two months after the surgery.
After the operation, patients are given an eye shield to be used when sleeping. Patients are advised not to rub their eyes and to keep the affected eye clean and dry.
IOL focus light beams onto the retina so that distant objects appear sharp without glasses. It is placed into the capsular bag at the end of Cataract surgery.
There are rare instances that a repeat surgery may be required to adjust the IOL rotation.
