Small Incision Cataract Surgery

Cataracts are the leading cause of blindness in people. Cataracts have a variety of symptoms that can worsen over time — blurriness, double vision, difficulty seeing at night or in light, and colors that seem faded. Cataracts are a progressive ailment and should be treated properly once symptoms are being noticed. There are a number of ways that cataracts can be treated. Initial options to treat cataracts are receiving a stronger prescription on your glasses, anti-glare sunglasses, or even magnifying lenses. In more progressive cases of cataracts, a surgical procedure may need to take place in order to restore proper vision. One of the surgeries that can be performed is called a Small-incision cataract surgery, (SICS) sometimes referred to as manual small-incision cataract surgery or sutureless extra-capsular cataract extraction. This article will briefly talk about what cataracts are and how a SICS procedure can help restore vision.

What Are Cataracts?

Every person has a lens in their eye that helps them filter light and perceive objects. Cataracts cause your lens to become cloudy, ultimately affecting your vision. Cataracts can be caused by a number of reasons why people get cataracts, but the main cause is age. The proteins in your eye that make up the lens start to deteriorate as you age and is a gradual process. Other causes can include Diabetes, eye injury, medications, or prolonged sun exposure. I severe cases, a surgery like a SICS can be performed.

Small-Incision Cataract Surgery

A SICS is a proficient and cost-effective procedure that can replace your natural lens with an intraocular lens or IOL. The surgeon will have to make an incision to get to the lens and be able to extract it without disrupting the cornea. Once the clouded lens is out, the surgeon will replace is with an artificial lens that is correctly tuned to your eye. The IOL can either be monofocal, multifocal or accommodative. The IOL will allow you to focus on certain ranges of distance depending on what kind of IOL you have inserted.

A SICS is estimated to have eighty percent of the improved vision in patients that undergo the surgery. Even with a high success rate, it is vital to find a competent surgeon to perform the surgery!

Smart Contact Lenses

The Hargrave Eye Center’s latest post:

Recent advancements in technology have sparked the innovation of smart wearable tech. Smart watches and Virtual Reality headsets are just two examples of very popular smart technologies that have taken off over the last few years. Smart contact lenses are on the rise and in development with many tech companies. Smart contact lenses open a plethora of doors for individuals and have a significant amount of potential to help people in various ways.


A company called Medella Health has recently been working on contact lenses that could potentially help people identify their blood glucose level. The way the contact lens would track the glucose level would be through tears of the individual. Once the information is gathered, the micro-antenna in the contact will send a message to the individual’s smartphone with the information. The contact lens has a sensor and a chip installed in it to be able to track the information. Another company called Verily is starting to create similar smart technology for patients, but instead of it being a contact lens, the product would be an injection into one’s eye.

Past and Future

Information gathering smart lenses are still in the preliminary stages. We have come a long with wearable smart technology before. Smart contact lenses have helped people cure their color blindness and implementing multi-focal lenses instead of monofocal. The next step would be gathering information from the human body to determine health risks such as the  low-blood-sugar which companies like Medella and Verily are developing now. Thinking even further in the future would be to incorporate Augmented Reality into contact lenses. Augmented Reality (AR) is required to be either location-based or image-based. Whether it be location or image-based, AR contact lenses would need to have a camera or GPS in them to work properly. One company called Emacula is looking to create a contact lens that seamlessly integrates AR technology into their product.

An even further leap into smart tech for contact lenses would be to use Virtual Reality in contact lenses. Virtual Reality requires motion sensors for people to experience it accurately. Unlike Augmented Reality, there is no need for a camera or a GPS signal to work appropriately for VR. Virtual and Augmented Reality will open a whole new world for people and has unlimited potential to change the lives of many people.

Eye Floaters

The Hargrave Eye Center’s latest post:

You see a strange-shaped figure in your vision that looks like cobwebs or specks of dust but, what are they? You may have experienced eye floaters at one point in your life but have you ever wondered what causes them? Eye floaters are caused by a detachment from the vitreous in the eye. The vitreous is a gel-like substance that helps the eye maintain it’s round shape. Millions of fibers run through the vitreous and attach to the retina. When these fibers break, detach, or begin to shrink, people begin to see floaters in there vision. Although these floaters should not cause immediate alarm, they should be monitored carefully, so they do not cause further problems.


What Are Eye Floaters?


Eye floaters are small spots in your vision that can take a variety of forms. Some eye floaters have been noted to look like cobwebs, strings, and other odd shapes. In addition to the vitreous detachment, temporary floaters can be caused by looking at something very bright. Other causes could be more serious like eye diseases, injuries to the eyes, infection, or even inflammation of the eyes. Enough floaters in your eyes could cause a problem, and there is a time when you should seek treatment from a healthcare professional.


Other Causes


Over time, the vitreous changes and can affect our vision. The vitreous can sometimes begin to liquify and detach from the retina otherwise known as retina detachment. With the vitreous shrinking or liquifying, it can clump together causing floaters in one’s vision. Inflammation or bleeding in the eye can cause eye floaters. Blood cells in the vitreous can be seen as floaters. Inflammation in the back of the eye can cause eye floaters by having inflammatory debris enter into the vitreous.  


Treatment Options


In extreme cases, treatment options can include surgery to replace the vitreous. Replacing the vitreous is called a vitrectomy. A vitrectomy is not common in these cases, and other options can be pursued beforehand. If eye floaters are clouding your vision, laser surgery can be used to help alleviate them. Consistent follow-up exams will be needed for either procedure.


If you have consistent or lasting eye floaters for over several weeks, visit your eye doctor for treatment options!
