Do Starfish Have Eyes?

The next time you stumble across a starfish while swimming in the ocean, gaze into his arms to see if he notices you. That’s right…his arms!

Oddly enough, most starfish have primitive compound eyes on the tips of each of their arms. A recent study showed demonstrated that starfish use these eyes to process visual information, especially when there was a need to locate food sources. Two groups of starfish were studied: one group with eyes and one group without. The two groups were placed in a sandy area of the ocean and studied how they moved toward the coral reef, which was their food source. The group with eyes was able to navigate directly toward the reef, while the group without eyes wandered aimlessly.

Additional studies into starfish may help researchers learn more about eye evolution.

Researchers are also continually studying human eyes and devising new technologies to correct vision problems. For example, in the past if you were nearsighted, farsighted or had astigmatism, you were stuck wearing glasses or contact lenses for life. Today, people have options, such as LASIK laser vision correction, to potentially eliminate their need for corrective lenses.

That means swimming in the ocean (and checking out the starfish) with clear vision using just a regular snorkel/diving mask or goggles.

If seeing starfish and other sea creatures more clearly sounds attractive to you, contact Charleston Cornea & Refractive Surgery at 843-856-5275 or charlestoncornea.com today to schedule your free LASIK Consultation. Dr. O'Day isn't an expert on starfish, but he has extensive experience in helping qualified candidates improve their vision. 

National Eye Exam Month Has Arrived

August is National Eye Exam Month. This observance is a good reminder about the importance of having regular eye exams. Often people take their vision for granted, especially if they don’t need to wear corrective lenses. Even those who are nearsighted, farsighted or have astigmatism might become complacent about exams if their vision is stable.

The Mayo Clinic recommends the following guidelines for a healthy eye exam schedule:

·         Children: before entering first grade, then every two years

·         Healthy adults up to age 40: every 5-10 years

·         Adults age 40-65: every 2-4 years

·         Adults over age 65: every 1-2 years

Of course, if you have any family history of eye disease or vision problems, you should schedule eye exams more frequently.

Why Eye Exams are Important

Eye exams can detect vision problems that you may be completely unaware of (like glaucoma or cataracts), and allow for the earliest treatment possible. Some vision conditions can lead to blindness if left untreated, so early detection gives you the opportunity to consider a wider range of treatment options.

You may also learn that you are a good candidate for a vision correction surgery, like LASIK, which could reduce or even eliminate your need for glasses or contact lenses.

Be honest: when was the last time you had an eye exam? Don’t put it off another year. Schedule a free LASIK Consultation at Charleston Cornea & Refractive Surgery. You can schedule it online at charlestoncornea.com or by calling 843-856-5275.

Potential Risks of LASIK Surgery

If you ever have a doctor tell you that there are no potential complications of LASIK, run the other way – and don’t look back! LASIK eye surgery, not unlike any type of surgery, carries with it possible risks. More than 14 million Americans have had LASIK, and if you search hard enough, you will find people who are willing to share their LASIK horror stories.

You may hear of LASIK patients who experienced:

·         Temporary vision problems and discomfort, such as light sensitivity, halos, glare, double vision or hazy vision

·         Corneal flap complications (this is the flap that is created on your cornea to allow the surgeon access to reshape your underlying corneal tissue and correct your refractive error), such as flap wrinkles, irregular healing, inflammation under the flap, epithelial ingrowth

·         Decreased tear production leading to dry eyes

·         Need for glasses after surgery due to incomplete vision correction

·         Eye infection

·         Vision loss

People who do report negative outcomes of LASIK may be the receiving end of:

·         Inferior technologies

·         Inexperienced surgeon

·         Not being a suitable candidate for LASIK in the first place

The fact is that LASIK has an overall excellent safety record and very high success rates for the majority of people who want to reverse their nearsightedness, farsightedness or astigmatism. Studies in the 1990s showed that up to 5% of people who had laser vision correction had some type of problem; today this percentage is under 1% for serious complications. When you are researching different LASIK providers, be sure to ask them hard questions to find out what their LASIK success rates are. If the surgeon isn’t willing or able to provide you with a satisfactory answer, keep looking.

A LASIK Consultation will provide answers as to your candidacy for this popular procedure. Your eye health and unique vision characteristics may not be suitable for LASIK, and the Consultation is the only way to properly determine this.
