When your ophthalmologist tells you that you have cataracts, he’s referring to the cloudiness on the lenses in your eyes.
Cataracts can happen in one or both eyes and are closely related to ageing. The lens that develops a cloudy abnormality lies on the top of your eye.
It’s the clear part that focuses light on your retina, which sits at the back of your eye. When light hits the retina, it sends signals to your brain and delivers the images you take for granted. If there is a cloudy covering on the lens, your vision is blurred too.
Glaucoma is the term describing a group of eye diseases associated with damage to the optic nerve, which is the nerve that connects your eye to your brain and transmits signals back and forth.
Glaucoma is the leading cause of irreversible blindness and often appears without warning, with no symptoms. When symptoms of glaucoma manifest, it’s often too late, and vision loss has already begun.
Management is a step by step process, usually starting with drops, but treatment would include or progress to laser and surgery. Your ophthalmologist will discuss the best option for you.
LASIK AND PRK SURGERY
Laser-assisted in situ keratomileusis (LASIK) and Photorefractive keratectomy (PRK) are both laser surgery techniques used to help improve eyesight. PRK has been around longer, but both surgeries are still widely used today. PRK and LASIK are both used to reshape the cornea in an effort to correct vision problems.
