Common Complications With Cataract Surgery

For most patients, cataract surgery remains safe but some people face difficulties after surgeries. These problems could be due to carelessness on the part of surgeons or patients.


 Germs could enter your eye at the operation table and develop infection that would result in pain, redness in eye and vision related problems. But it can be cured with a shot of antibiotics or with removal of vitreous, the clear gel in eye, in rare cases.


 A little swelling and redness post surgical treatment is considered normal but you can get it treated with eye drops, if you find it difficult to cope with inflammation.

Retinal Detachment

 The surgery could pull the retina away from its natural position leading to detachment. Located at the back of eye, retina does the job of sensing light and sending messages to brain. But this condition demands attention as it could lead to loss of vision. See your doctor if you have any of the following issues:

  • Feeling like a part of the eye is covered
  • View new floating spots in eye
  • See flashes of light

Lens Fragments

Surgery could lead to fragmentation of cloudy lens and a few pieces of the lens could be left in the eye. They need to be removed with a second surgery.

Fluid Buildup in the Retina

Surgery could puncture blood vessels leading to bleeding and fluid buildup in the Retina. It creates blurred vision but it curable with eye drops or sometimes with steroid.

Dislocated Intraocular Lens (IOL)

The IOL is the lens replaced with the cloudy lens. Sometimes the lens slips from its position causing vision problems. But sometimes it could lead to serious issues like bleeding. A correction surgery is needed to set the lens in the eye.

Secondary Cataract

The surgery removes only the front part of the cloudy lens leaving the back part in the eye. It is this part of eye that could develop secondary cataract called posterior capsule opacification (PCO). It is cataract that requires a second surgery called YAG laser capsulotomy.

Swelling in the Cornea

The front part of the eye is called cornea. This part remains clear but a cataract surgery might cause it to swell. But the problem subsides within a few days or your doctor might prescribe an eye drop for cornea.
