THE POTENTIAL COMPLICATIONS OF CATARACT SURGERY

A COMPREHENSIVE DISCUSSION WHICH SHALL BE PERSONALISED WHERE NECESSARY

Overall complications are rare (less than 1%), ranging from mild to severe:

Corneal abrasion - Where the surface of your eye gets scratched during operation (1:5,000). This is easily treated with antibiotic eye drops

Ecchymosis – Bruising of eye or eyelids (1:10,000). Bleeding behind eyeball – rarely severe.

Allergy – Causing an itchy swollen eye (1:500). This usually settles.

Posterior capsular opacification – Clouding of the membrane behind the implant (early 1:100; late 20:100). This is treated with laser.

Post operative glaucoma – Raised pressure in the eye. This may require treatment (1:500).

Cystoid macular oedema – Poor vision due to inflammatory fluid in the centre of the retina. This is usually mild and needs no treatment. It can be severe and require prolonged treatment (1:250).

Optical aberrations – Glare and starbursts in bright light conditions (virtually never).

Iris damage – Leading to an irregular pupil. This is usually optically insignificant (virtually never).

Ptosis – Droopy eyelid. This can be surgically corrected (virtually never).

Posterior capsule rupture and / or vitreous prolapse – A split in the thin back wall of the cataract (1:500). Requires a longer than average time to complete the surgery. At a higher risk of inflammation, glaucoma and reduced vision after surgery. May require second operation.

Refractive surprise – Unexpectedly large (or different from expected) need for glasses (never occurred). May require second operation.

Double vision - May need prism or rarely surgery (never occurred).

Dropped nucleus – The cataract falls deeper in the eye, needing another operation to remove it (1:10,000).

Dislocation of the lens implant – Movement out of position of the new lens. May require further surgery (1:10,000).

Suprachorodial haemorrhage – Bleeding inside the eye, which may require further surgery (never occurred). Risk of blindness / loss of eye.

Corneal decompensation – Clouding of the normally clear front window of the eye (never occurred). Can be painful. May need a corneal graft operation to restore vision and / or comfort.

Detached retina – Peeling off of the light sensitive layer within the eye (never occurred). Requires further surgery to repair.

Endophthalmitis – Rare severe (usually painful) infection inside the eye, which can lead to blindness (1:10,000). Treated with powerful antibiotics into the eye, but with often poor outcomes, and sometimes loss of eye.

Sympathetic Ophthalmitis – Inflammation occurring in sympathy in the fellow eye (never occurred).

Death – Incredibly rare with modern anaesthetic techniques (never occurred).
