Cataract

Risks & complications

Cataract surgery is the most commonly performed surgical procedure in the world and among the safest. No surgical procedure, however, can be guaranteed 100% safe. Below you'll find honest information about possible complications.

Post-operative eye drops — infection and inflammation prevention
Post-operative drops substantially reduce the risk of infection and inflammation.
In numbers

Less than 5% risk of complications

Serious complications are rare. Risk can be increased by certain conditions or unusual eye anatomy. During the pre-operative work-up we identify these and discuss them openly with you.

When is risk increased?

Some conditions or eye features increase risk:

  • High myopia or high hyperopia
  • Corneal damage (scar, dystrophy)
  • A very hard lens nucleus (advanced, "white" cataract)
  • Poor pupil dilation
  • Pseudoexfoliation syndrome (weak lens-support system)
  • Previous eye surgery

Serious complications (rare)

Endophthalmitis (infection)

Acute eye infection — less than 1 in 1000. Requires urgent treatment.

Intraocular bleeding

Bleeding inside the eye during or after surgery.

Corneal oedema (Descemet)

Swelling of the cornea — usually transient, rarely persistent.

Macular oedema (Irvine-Gass)

Swelling of the central retina — temporary blurry vision, treatable.

Strong rise in eye pressure

Usually temporary; sometimes short course of drops needed.

Capsular tear

Tear in the lens capsule during surgery — sometimes a second procedure by a vitreoretinal surgeon is needed.

Milder complications

Occur a little more often and usually resolve spontaneously:

  • Transient bruising of the white of the eye (small red patch)
  • Delayed healing of the incision
  • Allergic reaction to the drops
  • Superficial inflammation of the ocular surface
  • Temporary rise in eye pressure
  • Minor corneal distortion (astigmatism)

Posterior capsule opacification (PCO)

In the months or years after surgery, the posterior lens capsule can become cloudy — known as after-cataract. This is not a complication of the operation itself and is easily treated with a short, painless laser treatment (YAG laser capsulotomy) at the practice. The treatment is largely reimbursed.

How do we minimise the risk?

  • Extensive pre-operative work-up (biometry, OCT, topography, endothelial measurement)
  • Sterile operating environment in a dedicated ophthalmology suite
  • Modern phaco machines with low ultrasound energy
  • Strict post-operative drop schedule
  • Short-term check the day after surgery

During your pre-operative consultation Dr. Pinxten discusses all your questions about risk in detail and personally. You also receive a written information brochure.
