It is sophisticated microsurgical technique in which the vitreous gel is removed from inside the eye with a small, specialized cutting device with the help of an operating microscope to look into the eye, and microsurgical instruments.
The vitreous gel is then replaced with a clear saline fluid.
Vitrectomy is performed for many conditions including retinal detachment, diabetic retinopathy, macular pucker or hole, haemorrhage or infection inside the eye, and ocular trauma.
Vitrectomy is usually performed under local anaesthesia.
Refractive errors occur when the shape of the eye prevents light from focusing directly on the retina.
The most common types of refractive errors are myopia, hyperopia, presbyopia, and astigmatism.
- Myopia (near-sightedness) is a condition where objects up close appear clearly, while objects far away appear blurry.
- Hyperopia (farsightedness) is a common type of refractive error where distant objects may be seen more clearly than objects that are near.
- Astigmatism is a condition in which the eye does not focus light evenly onto the retina, the light-sensitive tissue at the back of the eye
- Presbyopia is an age-related condition in which the ability to focus up close becomes more difficult.
Eyeglasses or contact lenses are the simplest and safest way to correct refractive errors. Your eye care professional can prescribe appropriate lenses to correct your refractive error and give you optimal vision. Refractive Surgery aims to change the shape of the cornea permanently.
Squint is a condition where the two eyes are misaligned. That is both eyes do not appear to be looking in the same direction. One eye may be looking at an object and the other eye may be turned in or out or up or down.
Squints are more commonly seen in children. The condition affects 2% of children under 3 years and 3% of children and young adults.
