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 excimerlaser 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!

Understanding LASIK Incisions

LASIK eye surgery has brought lens-free vision to literally millions of people over the years. Technology continues to improve this medical procedure, making the outcomes more precise than ever before.

So why hasn’t everyone jumped on the LASIK bandwagon? Fear is one factor that keeps some people away. Specifically, fear of the LASIK incision. Let’s face it: our eyes are sensitive, and the thought of having a procedure that involves cutting the cornea can be scary. When you have detailed information about the procedure, you can make an informed decision about whether or not to pursue LASIK.

Type of LASIK Incisions

In LASIK surgery, the surgeon makes a thin flap in the cornea via one of two methods:

·         Mechanical tool called a Microkeratome. This is an oscillating, hand-held blade that is controlled by the surgeon.

·         Femtosecond laser also referred to as “bladeless” LASIK. Pre-calculated computer software guides the laser beam to cut the flap at a precise diameter and depth.

The corneal flap is folded back to allow the surgeon to reshape the cornea and correct nearsightedness, farsightedness and astigmatism issues. When the refractive error work is completed, the surgeon folds the corneal flap back down, where it heals itself. The whole process only takes minutes per eye! And most patients are already experiencing improved vision when they leave the office.

The truth of the matter is that LASIK surgery is quite safe when it is performed by an experienced LASIK surgeon. The Food and Drug Administration has approved nearly 30 lasers; lasers they have deemed to be safe and effective for LASIK surgery. There have also been advances in the microkeratome technology that have increased the effectiveness of the hand-held blade method.
