What are the complications of cataract surgery?
Cataract surgery is one of the most successful surgeries. Over 90% of patients operated for cataract gain a useful vision. But like any other surgery, problems may develop occasionally. If any of these complications occur, you should contact your surgeon immediately.
• Infection following cataract surgery is very uncommon but can be serious. There may be decrease in vision and the eye may become red and painful. This is an emergency, and you must contact your ophthalmologist immediately.
• Inflammation of the eye: This is called uveitis. The eye may become red and aching. This can be treated with drops.
• An accumulation of fluid in the retina may occur causing blurring of the central vision - this is known as cystoid macular edema. This usually resolves itself within a couple of weeks using drops.
• The implanted lens may occasionally move from its original position causing distorted vision. If this happens, further surgery may be needed to reposition the displaced lens.
• The retina may become separate from the inner wall of the eye. This is referred to as a retinal detachment and may require surgery. If you notice a shadow in your field of vision, floaters or flashing lights, immediately report to your surgeon.
• Thickening of the membrane behind the new lens can occur in the months following surgery. This is referred to as capsular opacity or 'aftercataract'. Although the vision becomes blurred it can be treated with laser.
