Presbyopia is the slow, but progressive loss of near vision due to the gradual hardening of the natural lens of the eye. This hardening irreversibly reduces the lens' ability to change shape (accommodation). It is surprising but we have all lost about 50% of our accommodation by...
No single person invented LASIK. Rather, it was the child of a marriage of two different, early myopia (nearsightedness) correcting procedures: 1) Keratomileusis and 2) PRK (PhotoRefractive Keratoplasty). Pioneered by Columbian ophthalmologist, José Barraquer, in Bogotà, Keratomilieusis reshaped the cornea mechanically. A micro-blade removed the front half of the cornea which was then...
The decision of whether LASIK is "worth it" depends on how unhappy you are with your current vision. You might imagine the out-of-pocket cost of LASIK would be directly related to how nearsighted you are: you would be getting more "value" for the money treating...
I imagine you mean can there be problems with one's vision or eyes from having LASIK that do not show up until years later. For the most part, if there was good patient selection and an initial good visual result, the answer is "No." Most...
I am not sure what you mean exactly by "sensitive eyes" but I am assuming you may be referring to chronic irritation, redness, or perhaps dryness. Any laser vision treatment of the your eye's cornea is going to change it permanently. Most of these changes are very good...
The lightweight, unobtrusive nature of contact lenses has made them a popular choice for vision correction. If you've ever had a pair of eyeglasses fly off during a gym workout, or had them fog up on a cold day, then you can appreciate the freedom...
Your question illustrates the unintended consequences of using what is arguably an outdated term: "cataract." Being 1) a noun and 2) requiring surgical removal to fix, a "cataract" seems similar in nature to a "tumor" or a "gall bladder." But "cataract" is the word we inherited...
Contact lenses have come a long way since the late 1800s, when the earliest models were made from blown glass. New contact lens technology is constantly being developed, resulting in more comfortable, safe, and effective lenses made from better materials. Check out a few of...
What vitamins are good for your eyes? Some vitamins and minerals may help maintain good eye health, and getting extra amounts of these won't hurt you. Most of us living in the United States are fortunate enough to enjoy a quality diet and don't have...
We see with our eyes, right? Surprisingly perhaps, but the answer is "No." We see with our brain, the part with the most neuronal connections, by the way. The Occipital Cortex is dedicated to assembling the most useful virtual image of all that sensory data coming...
