Laser-Assisted in Situ Keratomileusis (LASIK) uses a computer controlled laser to reshape the eye's cornea ( the transparent part in the front region of the eye), so as to enable light passing through it to focus correctly onto the retina of the eye.
When do you need this surgery?
This surgical procedure is ideal for people having following conditions making spectacle use mandatory :
1. Myopia or nearsightedness - Far off objects appears blurry
2. Hypermetropia or farsightedness - Close objects appear indistinct
3. Astigmatism - Overall fuzzy vision
Facts about the surgery -
- Practically painless procedure done under numbing drops
- Short surgery time as well as recovery time
- No use of stitches
- Reduced dependency on glasses and contact lenses
- Better vision as compared to vision through high power glasses
- Minimum age to opt for the procedure is 18 years
LASIK in Presbyopia or Presbylasik:
The surgery can also be opted for individuals who suffer from presbyopia, which is long-sightedness brought on by the loss of flexibility of the eye lens, and usually occurs in individuals in their middle and old age. The condition renders individuals with the inability to focus on objects that are close by, leading to difficulty in reading smaller prints or doing chores close up.
In Presbylasik or Multifocal LASIK different power zones are created for seeing at varying distances - near , intermediate and distance vision. Consulting a doctor is best as he or she can help you to decide on the right course of action.
I am 38 years ,getting speedy stain and eyes, body is not flexible, mind sharpness is falling, please help.
Doc. I got viral conjunctivitis on both of my eyes. I got cleared one month back. After that I started to see lot of floaters on my eyes and my vision also became poor. I visited the opt. And they told me I got corneal scarring. My doc. Prescribed me lotepred 0.5 ml, which I have used nearly for a month. Now my vision has improved, doc. Examined and told me that the corneal scar has cleared but still I see mild floaters and specks on day light. I am not do diabetic and my BP is normal. After conjunctivitis only I am seeing this. What could be the reason doc? Pls help me out. Thanks.
Sir I have the problem of weak eye sight and my eye sight is getting weak now also so what to do for that Tell me diet for that.
Hello, my 4 year daughter's visual acuity is 6/18 in both eyes with use of glasses with following power (O.D. +1.0 spherical, -3.32 cylindrical 10 degree axis) AND (O.S +0.75 spherical, -3.0 cylindrical 180 degree axis). I am concerned about the development of her vision. Our ophthalmologist says she is expecting a good vision within 1 year of regular eyeglasses use. Is it amblyopia / lazy eye and should we look for any further treatment like pleoptic exercises for her? We have not been advised anything in this regard by our ophthalmologist. As per her she will have normal 6/6 vision within one year. Please guide.
Sir, I have a small sight I want to go for laser treatment is it a better idea? Or is there any alternative to cure my sight permanently? Is laser treatment done for all age groups? Will there be any side effects after laser treatment?
Amblyopia is commonly known as 'Lazy Eye'. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to 'see' and develop binocularity, that is the ability to perceive depth (Stereoacuity). This occurs in the first 8 to 10 years of life.
Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions ( adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to 'see' and becomes 'lazy'. This condition is seen in 1-4% of population.
The common causes for dissimilar images or Amblyopia are:
1. Misalignment of the eyes or squint: It is the primary reason for Amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different , resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.
2. Refractive Amblyopia:
- Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5D of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
- High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.
3. Cloudiness in visual system or visual deprivation Amblyopia: Any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to Amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood( drooping of one eyelid, eyelid swelling, patching of one eye).
Treatment for Amblyopia: For treatment of Amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.
Patching or occlusion of the good eye: This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye 'learns to see'. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.
To be effective, treatment should be implement as early as possible , within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.
