Cataract services & Intraocular Lens
Cataract Serivces
How a cataract looks?
In a normal eye, the lens-which lies behind the pupil-is clear (transparent), so the pupil appears black. In an eye with a severe cataract, the cataract clouds the lens. So the pupil may look gray or cloudy.
Incision for surgical instrument is made –
Two small cuts (incisions) are made in the eye where the clear front covering of the eye (cornea) meets the white of the eye (sclera). Next, a small, circular opening is made in the front of the lens capsule to allow access to the cataract. A small surgical instrument (phaco probe) is inserted into the eye.
Intraocular Lens (IOL)
A variety of IOL types are available to replace your natural lens. After the cataract is removed, an intraocular lens (IOL) may be placed inside the lens capsule. The intraocular lens (IOL) takes the place of the eye’s natural lens. The incision does not usually require stitches, unless the surgeon decides they are needed.
Foldable IOL –
They can be placed into the eye through a much smaller incision. These implants have flexible optic lenses made of acrylic or solid silicone. They can be placed into the eye through a self-sealing incision as small as 1/8th of an inch. Through the small incision, the cataract is broken apart with an ultrasound device and gently vacuumed from the eye. These small incisions do not induce significant changes in the patient’s astigmatism seen with larger incisions of the past, thus results are more predictable.
Multifocal IOL –
These IOLs provide both distance and near focus at the same time. The lens has different zones set at different powers. It is designed so that your brain learns to select the right focus automatically.
Toric IOL –
For people with astigmatism, there is an IOL called a toric lens. Astigmatism is a refractive error caused by an uneven curve in your cornea or lens. The toric lens is designed to correct that refractive error .
