Can Cataract Surgery Be Redone? An Expert's Perspective

Cataract surgery is a common and essential procedure that can significantly improve the quality of life for the patient and reduce the need for other forms of treatment. However, many people wonder if the surgery can be done again if the patient develops complications. In this article, an expert will discuss the potential causes of cloudy vision, double vision, and glare after cataract surgery, as well as the possibility of redoing the procedure.

Cloudy Vision

The cloudy natural lens is removed during cataract surgery, and a clear lens is implanted. This allows the eye to see more clearly without glasses. After surgery, patients may experience a few days of cloudy vision. This can be due to inflammation in the eye, which can be treated with anti-inflammatory eye drops. Other causes of cloudy vision include infection, macular degeneration, diabetic retinopathy, dryness, and a retained cataract fragment.

Double Vision

Having double vision after cataract surgery can be very disturbing for the patient and physician. The reason for this is the change in visual acuity caused by the new lens. The underlying etiology is not always easy to determine. For instance, patients with anisometropia, a preexisting misalignment, can be asymptomatic. Other causes of double vision include decompensation of preexisting phoria, sensory exotropia, binocular diplopia, and topical anesthesia.


During cataract surgery, a cataract is removed from your eye and replaced by a clear artificial lens. This clear artificial lens doesn't block light as the cataract did before. However, some people still experience glare when looking at a light source. This glare is most noticeable when you are looking at a light source and is caused by diffraction when light bends as it enters your eye. There are several reasons why glare might occur after cataract surgery including corneal edema, corneal scarring, pupil size mismatch, and lens tilt or decentration.

Can Cataract Surgery Be Redone?

In some cases, it may be possible to redo cataract surgery if complications arise after the initial procedure. However, it is important to note that redoing cataract surgery is not always necessary or recommended. If you experience any of the symptoms discussed above after your cataract surgery, it is important to speak with your doctor about your options. Your doctor will be able to assess your condition and determine if redoing the procedure is necessary or if there are other treatments that may be more effective.
