What are the potential short-term side effects of cataract surgery?
In the first days and weeks, it's common to have mild blurring, scratchiness, dryness, light sensitivity, tearing, glare or halos, a bloodshot eye, or fluctuating vision as the eye heals and settles. Most of this improves within a few months, though full comfort can take up to a year. Certain symptoms are not routine: increasing pain, worsening redness, a sudden drop in vision, or new flashes, floaters, or a curtain in your side vision need urgent evaluation, so call rather than wait.

Complications after cataract surgery are rare... but short-term side effects are common. Knowing which side effects to expect will help you feel more in control and have a smoother recovery. Cataract surgery side effects include eye dryness, because your eye makes fewer tears for about 3 months after surgery. Some sensitivity to light is also common because your eyes are more dry. Blurry vision is caused by swelling after surgery and may last for weeks. Glare and halos are most common at night and probably caused by the artificial lens used in surgery. A red (or bloodshot) eye is usually caused by inflammation or a broken blood vessel. A droopy eyelid often comes from swelling after surgery or pulling back your lid during surgery. Most side effects of cataract surgery won't last more than a few months, but patience is important; it may take up to a year for your eyes to feel normal. If you notice flashes of light, shadows in your side vision, or eye redness with other vision symptoms, call your doctor right away
