Sure, you’ve probably heard the hype about Lasik surgery; in fact, you probably know a few people yourself who have benefitted from this corrective procedure. After all, giving up contact and glasses for good is a BIG reason to celebrate. But our patients are often confused about the difference between cataract surgery and Lasik surgery.
These procedures are actually quite different and are used to treat much different patients. Read on for clarification.
Lasik surgery is a procedure that uses a laser beam to actually re-sculpt the surface of the cornea –the transparent front covering of the eye – to create a more rounded shape. Lasik actually stands for “laser in situ keratomileusis.” That’s a mouthful!
During the Lasik procedure, your trained surgeon will create a small, thin hinged corneal flap, then pulls this flap back to expose the corneal tissue. He or she will then use a laser to reshape the cornea into the pre-specified pattern, which depends on the results of your Lasik eye exam.
Lasik surgery is a good option for patients who suffer from refractive error, which means that the eye’s natural “focusing system” is not perfectly focusing incoming light rays onto the surface of the retina, making images blurry at some point.
Cataract surgery, however, is a different procedure altogether. A cataract is an opacification—or clouding—of the lens of the eye. Cataracts vary in degrees of severity and can obstruct the passage of light into the eye, affecting overall vision.
Cataracts develop due to metabolic changes of the crystalline lens, and can become a serious issue for suffering patients.
Cataract surgery involves the surgical removal of the clouded lens of the eye. This is replaced by an artificial intraocular lens implant. Ophthalmologists perform cataract surgery using local anesthesia, and there is a low complication rate for this type of surgery.
