Cool Facts About Dolphin Eyes- Part 3

“A dolphin’s pupil has a type of built-in shade. When our eyes are exposed to light, our pupils get smaller to let less light in. Dolphins have a kind of lid, called an operculum, that slides down to cover most of the pupil when it is bright. It almost looks like two pupils when this ‘lid’ comes down.”

-          Joy Clausen Soto, Senior Dolphin Trainer at SeaWorld

Humans don’t have instant shades on our eyes. We have to wear sunglasses to protect our eyes from the harsh sun. When you are nearsighted, farsighted or have astigmatism, it’s often necessary for you to purchase expensive prescription sunglasses to be able to see in sunlight.

LASIK has allowed millions of Americans to expand their sunglasses collections with a multitude of cheap sunglasses by correcting their refractive errors.

In a LASIK procedure, a surgeon creates a thin flap on the cornea that is peeled back to allow access to the underlying corneal tissue. This can be done using a microkeratome or femtosecond laser. Once the flap has been created, an excimer laser is used to reshape the cornea (correct the refractive error) so it can properly focus light on the retina (the back of the eye). This is the actual vision correction step in the procedure. Once the cornea is reshaped, the flap is put back into place so it can heal. The entire procedure only takes minutes per eye.

Like any surgical procedure, LASIK does carry risks. You should always have an open discussion about all of the risks of LASIK with your surgeon before you make any decisions to move forward with the procedure. You should also remember that even if you have 20/20 vision, it’s still important to wear sunglasses to protect your eyes. You’re not a dolphin, after all!

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.
