Vision usually improves quickly (within a few days) following cataract surgery. For some, vision may be excellent within hours. For others, it may take several days or even a few weeks to return to normal. This longer interval does not necessarily indicate any complication or failure of the surgery. During the healing process, you may be surprised by changes in color: because the clouded lens, which commonly filters out some colors, has been removed, colors may appear more luminous or seem to have a bluish glow. Spending time in bright sunlight may give objects a reddish afterimage when you come indoors.
Sticky eyelids, itching, sensitivity to light, and mild tearing are perfectly normal after surgery, but severe pain and sudden changes in vision are unusual and warrant an immediate call to your doctor. Patients who suffer minor discomfort can take a non-aspirin pain reliever such as acetaminophen (Tylenol) every four to six hours. Any discomfort should subside on its own within a day or two.
The ophthalmologist will schedule several postoperative visits: the day after surgery, after about a week, at three to four weeks, and then usually six to eight weeks later. The doctor will examine your eye, test your visual acuity, and measure eye pressure. Corrections for eyeglasses will probably not be prescribed until three to six weeks following surgery.
