Lasik stands for Laser assisted in-situ Keratomileusis and is done for short sightedness, long sightedness and cylindrical power.
The ideal candidate is over 18 years of age with healthy eyes and stable vision. LASIK treatment can correct a wide range of near-sightedness, farsightedness and astigmatism.
Nearsightedness (myopia) is a common cause of blurred vision. It can be mild, moderate, or severe. If you are nearsighted, objects in the distance appear blurry and out of focus. You might squint or frown when trying to see distant objects clearly. These problems cause light rays entering the eye to focus in front of the retina . Normally, light focuses directly on the retina.
Farsightedness or hyperopic means that the eye focuses better on distant objects than on those that are close. Adults with hyperopic or farsightedness may have difficulty focusing on objects close up, such as print in a book. As they mature, these same adults may have difficulty focusing on distant objects, as well. If the eye is too short, or the focusing power too weak, the image is focused behind the retina. At the retinal surface, the image is blurred. Thus, the vision, too, is blurred. Hyperopic often runs in families. It is often present at birth; however, many children outgrow it.
Astigmatism is characterized by an irregular curvature of the cornea. This is one type of refractive error. Astigmatism occurs in nearly everybody to some degree. For significant curvature, treatment is required. A person’s eye is naturally spherical in shape. Under normal circumstances, when light enters the eye, it refracts evenly, creating a clear view of the object. However, the eye of a person with astigmatism is shaped more like a football or the back of a spoon. For this person, when light enters the eye it is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. Objects at any distance can appear blurry and wavy.
Because of high power or thin cornea, if patient is not suitable for Lasik, ICL will be the option provided if ACD is more than 2.8mm (Measured using Orbs Scan).
Near sightedness, farsightedness and astigmatism.
Glaucoma is a group of diseases that can damage the eye’s optic nerve and result in vision loss and blindness. The most common form of the disease is open-angle glaucoma. With early treatment, you can often protect your eyes against serious vision loss.
The optic nerve is a bundle of more than 1 million nerve fibers. It connects the retina to the brain.
Open-angle glaucoma is the most common form of glaucoma. In the normal eye, the clear fluid leaves the anterior chamber at the open angle where the cornea and iris meet. When the fluid reaches the angle, it flows through a spongy meshwork, like a drain, and leaves the eye.
Not necessarily. Increased eye pressure means you are at risk for glaucoma, but does not mean you have the disease. A person has glaucoma only if the optic nerve is damaged. If you have increased eye pressure but no damage to the optic nerve, you do not have glaucoma. However, you are at risk. Follow the advice of your eye care professional.
Not necessarily. Not every person with increased eye pressure will develop glaucoma. Some people can tolerate higher eye pressure better than others. Also, a certain level of eye pressure may be high for one person but normal for another.
The eye is similar to a camera – cornea and lens focus the light on to the retina; the pupil works like a camera diaphragm, controls the amount of light entering in the eye.
The retina is the light sensitive layer which lines the inner wall of the eye. The retina converts the visual image in to a signal and brain reads the signal. Retina transmit the signal to brain through Optic nerve. The retina is similar to the film of a camera. Even if we have a expensive camera but film is not good, camera cannot take good picture. Similarly if Retina is affected due to any disease, vision is not clearly.
All the patients should go for retina checkup every year. This helps to treat the problem before it causes irreversible vision loss. Retinal checkup is especially important for Diabetic, Hypertensive patients and patient who wear glasses.
Doctor will see you and ask the nurse to put an eye drop to dilate your pupil (this allows a complete retinal examination). Eye drop takes 20-30 minutes to dilate the pupil then Retina specialist will examine you.
Retina Angiography (FFA & ICG)
Optical Coherence Tomography (OCT)
Ultrasound (B SCAN)
This is a simple test where an injection of a dye (Fluoresce in dye in FFA and indocynin green dye in ICG) is injected in your vein of hand and photographs are taken of your eye. This test helps to Retina specialist to make a decision about further treatment specially in cases of Diabetic Retinopathy, Age Related macular Degeneration (ARMD), Retinal Vein Occlusion etc.
Allowing transmission of light by its transparency helping the eye to focus light by refraction maintaining the structural.
Cornea may became damaged by disease or injury.
No, Corneal transplantation was started since 1936.
No, it can done for any age group.
You have to consult an ophthalmologist.
Child not looking at parents / lights and not playing with toys etc.
Child with white reflex in eyes (Cataract / RD / eye tumor etc…).
Child with defective vision / headache / eye pain. Child with deviated eyes (Squint).
Child with involuntary movements of eyes (Nystagmus).
Child with eye trauma.
Child with small sized eye ball or cornea.
Premature & low birth weight babies.
Child not fairing in school.
Complain of constant watering / discharge from eyes.
Child with frequent itching, redness, watering from eyes.
Child with systemic / metabolic disorders, neurological problems developmental delay etc…
Child with lid abnormalities (ptosis, hemangioma, coloboma etc..).
If parents are using spectacles then child should get annual checkup starting from two years of age.
If one child in a family is using glass then other siblings needs detail checkup.
Have your child examined before age of five years and then on a yearly basis through out the school years.
Amblyopic or Lazy eye is the term for poor vision in one or both eyes. It can result from refractive error, squint or other causes. This needs to be identified and treated at an early age to recover vision.
Nearsightedness simply means that is easier to see up close than far away. Usually this is because the eye is too long and brings light to focus before it reaches the retina. The eye has no mechanism for correcting that on its own, so a nearsighted person requires contact lenses or glasses to see clearly at distance. Though very young children may be nearsighted, nearsightedness more commonly shows up at age eight or nine, and tends to increase through the teens, eventually leveling off in the late teens. This increase in nearsightedness would occur whether glasses were worn or not; it is not the glasses that make the eyes get more nearsighted.
