Post Cataract Surgery Complications

A cataract resembles a thin film that can cloud the eye and create difficulty seeing. When the cataract begins to dramatically impede vision, an eye surgeon may recommend a procedure to remove the cataract. Major surgical complications are rare; however, the surgery is not without complications.

Decentered Intraocular Lens Implant

• During cataract surgery, an eye surgeon places a lens in the eye to enhance vision. It is possible that the lens can shift over time, shifting slightly or dramatically off center. This can cause a variety of symptoms, including blurry vision, glare, halos, double vision or shimmering vision. If this occurs, further surgery may be required.

Cystoid Macular Edema

• This condition can cause swelling in the macula, which is the retina's center. This swelling can cause blurring of the vision, particularly when looking straight ahead. If a patient experiences this symptom, it can be treated with a nonsteroidal anti-inflammatory medication, taken either via pill or applied as an eye drop.

Secondary Cataract

• According to the About Cataract Surgery website, a secondary cataract is the most common complication related to surgery. This results in a cataract buildup around the lens capsule, which can blur the vision. A secondary cataract can be treated via a laser procedure or through more invasive means, if necessary.

Retinal Detachment

• This complication risk is generally associated with those who are extremely nearsighted, as the retina is already somewhat detached. Symptoms include seeing floaters, flashes of light or a curve in vision. Retinal detachment is considered a medical emergency, meaning fast treatment is imperative.

Posterior Capsule Rupture

• When the cataract portion is removed during surgery, extra pressure is placed on the posterior capsule, which can sometimes cause it to tear or rupture. If this occurs, a surgeon must restore shape to the capsule to ensure successful implantation of the intraocular lens.
