LASIK or Lasik (laser-assisted in situ keratomileusis) is a type of refractive surgery for correcting myopia, hyperopia, and astigmatism. LASIK is performed by ophthalmologists using a laser.LASIK is similar to other surgical corrective procedures such as photorefractive keratectomy, PRK, (also called ASA, Advanced Surface Ablation) though it provides benefits such as faster patient recovery.Read More
A cataract is a clouding of the lens of the eye.
Factors that may speed up cataract formation are:
In many cases, the cause of cataract is unknown.Read More
Glaucoma refers to a group of eye conditions that lead to damage to the optic nerve (the nerve that carries visual information from the eye to the brain).In many cases, damage to the optic nerve is due to increased pressure in the eye, also known as intraocular pressure. Glaucoma is characterized by a particular pattern of progressive damage to the optic nerve that generally begins with a subtle loss of side vision (peripheral vision). If glaucoma is not diagnosed and treated, it can progress to loss of central vision and blindness.Read More
Wet macular degeneration is the result of the formation of new, fragile and leaky blood vessels growing under the retina. The growth of these new blood vessels is called angiogenesis.Read More
Myopia is a condition whereby images come into focus in front of the eye, resulting in a blurred image on the retina. The more severe the nearsightedness, the farther the image is from the retina, which results in more blurry vision in the distance.Read More
Retinal detachment is a separation of the light-sensitive membrane in the back of the eye (the retina) from its supporting layers. The retina is a transparent tissue in the back of the eye. It helps you see the images that are focused on it by the cornea and the lens. Retinal detachments are often associated with a tear or hole in the retina through which eye fluids may leak. This causes separation of the retina from the underlying tissues. If not promptly treated, retinal detachment can cause permanent vision loss.Read More
Retinitis pigmentosa (RP) is a group of genetic eye conditions that leads to incurable blindness. In the progression of symptoms for RP, night blindness generally precedes tunnel vision by years or even decades.Read More
At birth a baby's vision is very immature, with an acuity of around 3/60. Visual experience in infancy and childhood has a major influence on the development of the visual pathways, particularly the visual cortex. During the critical periods of visual development visual acuity develops as do other modalities such as contrast sensitivity, colour, pattern and motion perception, and binocular function with stereopsis.Read More
Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft) in its entirety (penetrating keratoplasty) or in part (lamellar keratoplasty).Read More
Keratoconus (from Greek: kerato- horn, cornea; and konos cone), is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than its normal gradual curve.Read More
Read on for some yogic eye exercises to strengthen eyes. They are easy to do and most of them can be performed any time of the day wherever you are.
Most of us do not exercise our eye muscles at all, but yet, we work them all the time, causing them to be under constant strain. The only time the eyes rest for more than a split second, is when we are asleep. Here are a few yogic eye exercises to strengthen eyes. They are easy to do, and most of them can be performed any time of the day, wherever you are.Read More
Dry eye syndrome is caused by a chronic lack of sufficient lubrication and moisture on the surface of the eye.
Its consequences range from subtle but constant irritation to inflammation of the anterior (front) tissues of the eye.
Dry eyes also are described by the medical term, keratitis sicca, which generally means decreased quality or quantity of tears. Keratoconjunctivitis sicca refers to eye dryness affecting both the cornea and the conjunctiva.Read More
