As we age, the lens of the eye becomes mistier and opaque. It’s similar to looking through a fog, or patchy vision, that makes it harder to focus. When you are young, the lens is clear, but as you age, the lens becomes more and more opaque than before.
A cataract begins yellowish in colour, then turns brown, and then eventually it goes white. As a cataract changes, it impairs the amount of light that can get into your eye. Removing the cataract allows you to see more light and enables you to focus again.
Cataracts are common – in fact we probably all know at least one or two people who have had cataracts treated. Nearly 1/3 of people over 65 have a cataract. The most frequent cause of cataracts is age-related degeneration of the lens in the eye. If you have a cataract, you will progressively lose your vision in time.
There are many risk factors for developing a cataract. We list a few of them below:
Causes of cataracts in younger patients include:
These are just some of the causes of cataracts in both adults and children – there are many more that I haven’t mentioned here. The critical thing to remember is that the most frequent cause of cataracts is the changes in the lens of the eye caused by aging. Because there are so many older people in Canada today than before there are a lot of people with cataracts that need treating.
A cataract assessment starts with taking a history. We’ll ask you detailed questions and explore all optical errors and other diseases in your family. For example, we’ll want to know whether you or any of your family members suffer from diabetes, high blood pressure, allergies or similar problems. We’ll also want to know the names of all of the medications that you take. We will measure the glasses you are using and will test your reading skills with and without glasses.
We will measure your refractive errors. We will check your intraocular pressure. The measurement of the intraocular pressure is crucial at any age because a higher intraocular pressure can signal a higher risk of glaucoma.
Furthermore, we will conduct a biometric examination as part of your pre-operative examination. That involves measuring your eye. We’ll use the data from that measurement for the calculation of your new artificial intraocular eye lens.
After that, we’ll conduct a Pentacam examination. A Pentacam measures the anterior (front) segment of the eye. We also examine the posterior (back) segment of the eye after we dilate your eyes. We will administer eye drops into your eyes, which will widen your pupil. The eye drops are entirely painless.
After we widen your pupil with these painless drops, we will take a photograph of your retina (the very back of your eye). In this step of the examination, we will uncover any potential hidden bleeding or damage to the retina. We will also scan for a disease called AMD (the age-related macular degeneration of the retina).
You will end your examination with a consultation with an ophthalmologist, who will perform a detailed analysis of the back eye segment of the eye. This eye doctor will be the one with whom you will discuss and choose the best treatment option to remove your cataract.
Eye surgeons perform 15 million cataract treatments each year making them the the most common eye procedures worldwide. At Clearview Institute we offer our patients cataract surgery to restore good vision at a distance, or to treat both the cataract and presbyopia with a procedure we call Customised Multifocal Intraocular Lens Replacement.
Both approaches involve removing your natural crystalline lens and replacing it with a high-resolution lens called an intraocular lens (IOL) implant. Today’s IOLs, medical device manufacturers design lenses to closely mimic the performance of a young and healthy eye.
Dear Dr. Kranemann, Many thanks in the nice, smooth and trouble free cataract surgery you carried out on both my eyes at Clearview Institute. I would like also to extend my thanks to all the staff of clearview. They are efficient, kind hearted and very helpful.
Dr. Kranemann is exceptionally intelligent and experienced. He is passionate about achieving perfect results for his patients, and proved it by correcting my father’s vision perfectly. We are very happy and grateful and highly recommend Dr. Kranemann.
Had the new vision correction procedure SMILE. WOW is all I can say. Life without glasses is amazing. Great surgeon and medical staff. Will refer his expertise on to family and friends.
