What is a Cataract?
Our natural lens, which is behind coloured part (iris) of eye, focusses light on retina and forms the image. This image is transferred to brain which finally makes us to see. When this lens becomes cloudy, we call it cataract. This cloudy lens (cataract) blocks and distort the light, hence clear image is not formed on retina.
How Can I Tell If I Have a Cataract?
If you are over 40 and notice your vision getting blurry for both near and far distances, even with glasses, you might have a cataract. You might also experience problems like glare from car headlights, faded colours, and difficulty seeing well in bright light or sunlight. Sometimes, bright lights like bulbs or the moon might appear as multiple images.
Can Cataracts Develop at a Young Age?
Yes, cataracts can develop at any age, from birth to old age. Several factors can contribute to cataracts, including poor diet, too much sun exposure, genetic factors, and smoking.
What is the Phaco Technique?
Phacoemulsification, often called "Phaco," is a modern method for cataract surgery. This technique uses a tiny incision, about 2.2 millimetres wide, to perform the surgery. The procedure causes minimal discomfort and allows for quicker recovery with less risk of astigmatism. A small needle uses ultrasound to break up the cataract, which is then removed. A new lens called a foldable Intraocular Lens is inserted through the same tiny opening.
How is the Phaco Technique Better Than Older Methods?
Phaco has several benefits over older methods. Most people can see well the day after surgery and resume normal activities quickly. Post-surgery care is less complicated, and you might not need glasses for daily activities. However, some fine adjustments might still need glasses.
Do I Have to Wait Until the Cataract is Fully Mature?
No, you don’t have to wait until the cataract is fully mature or white. It’s best to have surgery when your vision starts to affect your daily life. Waiting too long can make the cataract harder and the surgery more difficult. As one of the best eyecare centre in Patna, we use the latest technology for a smoother surgery experience.
Will I Need Glasses After Surgery if I Have an IOL (Lens) Implanted?
Monofocal IOLs are designed to give clear vision at either distance or near, so you might need reading glasses for close work. However, multifocal IOLs are available and can provide clear vision for both distance and near, though sometimes glasses may still be needed for excellent work.
What Types of IOLs Are Available?
IOLs (Intraocular Lenses) come in two main types: foldable and non-foldable. Foldable IOLs can be inserted through a tiny incision and unfold inside the eye, so no stitches are needed, and you can see clearly soon after. Non-foldable IOLs require a larger incision and stitches. Foldable IOLs, especially those made from hydrophobic acrylic, generally have fewer complications and better performance.
Can Cataracts Come Back After Surgery?
Cataracts do not come back after surgery. However, the membrane holding the IOL might thicken over time, causing blurry vision. This can be easily treated with a laser procedure in the doctor’s office, usually occurring between 1 and 5 years after surgery.
