Cataract surgery involves placing a plastic lens inside a lens capsule or bag which frequently becomes cloudy following cataract surgery resulting in misty or blurred vision. YAG laser can clear this cloudiness and is a quick, painless and safe procedure taking about 10 minutes. It involves making an opening in the cloudy part of the capsular bag to allow the light through for you to be able to see clearly. It has to be done only once.
Laser treatment for diabetic eye disease has been successfully used for over two decades now to minimise the risk of progression of diabetic eye disease and to prevent further visual loss which usually occurs due to poor control of diabetes or delaying treatment.
Laser is used to treat advanced diabetic eye disease called proliferative diabetic retinopathy where new vessels formation causes a bleed inside the eye due to their fragility resulting in further sight loss. Similarly, laser is used to treat macular oedema which is fluid leaking from blood vessels into the central part of your retina called the macula. Laser treatment is painless and takes about 15 minutes after using drops for local anaesthesia for comfort. Laser treatment is effective after a few months and may need to be repeated depending upon the control of diabetic eye disease.
However, the latest evidence shows the best visual outcomes in diabetic eye disease are achieved with the combined use of intravitreal injections and laser.
