You may assume that your eyes are healthy if you have no difficulty with your vision. Sometimes, we can determine that a glasses prescription can allow even better vision. Common eye diseases such as glaucoma, age related macular degeneration (ARMD),diabetic eye disease and early cataracts often have no symptoms at the early or even moderate stages. Early diagnosis and treatment can be very important.
Our goal at the Eye Surgery Institute is to allow you to keep optimal vision your entire life. Many diseases require diagnosis and treatment at early stages to help prevent vision loss in the future.
Many eye diseases can run in your family. It is important to know your family history of eye diseases. If you have a strong family history of eye problems, it is important to have more frequent eye examinations especially as you age.
It is important to wear safety eye protection especially when working with tools, machines or chemicals. This can include safety glasses, eye shields and goggles. Many are made of polycarbonate because it is much stronger and more protective. It is especially important to wear eye protection if you only have one eye that sees well.
It can be helpful to eat a healthy diet with lots of green, leafy vegetables. This can help prevent certain eye diseases such as macular degeneration.
It is useful to wear sunglasses when outside. This can help prevent against cataracts and macular degeneration. It is also helpful to not smoke. Smoking is bad for your overall health, including your eyes.
Lasik is an elective surgical procedure and the goal is improve vision and reduce or eliminate the need for glasses. We use a laser to correct nearsightedness, farsightedness, and/or astigmatism. The purpose of Lasik is to reshape the cornea so that the light rays entering into the eye are focused onto the retina.
With Lasik, a flap is created using either a microkeratome blade or a femtosecond laser. The flap is folded back and then the surgeon removes some corneal tissue underneath using an excimer laser. The purpose of the laser is to reshape the cornea so you are less dependent on glasses.
We need to make sure your glasses prescription is within certain limits and that your cornea has sufficient thickness. It is important to have your contact lenses out for several days prior to your surgery. We also need to check for irregularities of the cornea. Assuming you are a good candidate, we will discuss your options in detail.
What Can I Expect?
It is best to have someone drive you to your operation. Your eye will be numbed and you should be comfortable. Dr. Stanley Grandon or I will lay you back and perform the procedure while we are looking into a microscope.
After the surgery, your eye may feel a foreign body sensation, you may experience burning or itching. The vision may also be blurry. You will have drops to use for a few weeks and you will come into our office the next day for a checkup.
Astigmatism is a very common cause of blurry vision. The eye is shaped more like an egg or football rather than an orange. Either the cornea or the lens of the eye is not round if you have astigmatism. Instead it is oblong.
It is often hereditary and you are often born with it. Most people have astigmatism in their glasses prescription. The amount and direction can change over time. If you have astigmatism, objects can look elongated either vertically or horizontally.
Children and Astigmatism
It is important that astigmatism is diagnosed in children at an early age. Children may not complain of blurry vision. If your child has a lot of astigmatism that goes undiagnosed, the visual system may not develop properly. This can lead to a condition called amblyopia (lazy eye). If your child does not pass a screening evaluation at either their pediatrician or school, it is important that they have a comprehensive eye examination to determine the reason.
Undiagnosed astigmatism can cause blurry vision and possibly difficulty seeing at school. Refractive error is not affected if you child sits too close to the TV or reads in low light.
What Causes Astigmatism ?
Astigmatism can be caused by either the shape of the cornea or the lens. The cornea is the windshield of the eye and the lens focuses light inside the eye. If either structure is shaped more oblong, you may have astigmatism.
How Do I Treat Astigmatism?
You will want to have your astigmatism treated to provide the best possible vision. It can be treated with glasses and / or contact lenses. There are many contact lens options available.
If you have astigmatism and require cataract surgery, we can evaluate you for a special implant to correct the astigmatism. This implant is called a toric implant and can greatly reduce your dependency on glasses after cataract surgery.
