Dr. Nancy Ann Tanchel M.D.'s Expert Contributions
You will really enjoy your vision without glasses or contacts. You can expect to have great distance vision for many years, until you develop cataracts - hopefully in your 80's. Your up-close vision for reading and small things will become a problem at about age 45; at that time you will likely need over the counter reading glasses. So, for the next 8 years you can expect great far and near vision, with excellent distance vision for 40 or more years. Congratulations on getting laser eye surgery - it will be one of the happiest decisions you make for many years to come! READ MORE
During LASIK, there is a flap created on the surface of the eye, so laser can be delivered underneath, to correct our vision. The nerve endings in the flap have been cut, so the flap does not have sensation; the nerve endings will grow back and your tear film will eventually get back to normal. However, early in the healing process, your brain doesn't feel the surface of your eyes, so you make less tears than normal. You need to use artificial tears every 1 - 2 hours at the beginning to keep the surface healthy. The best tears to use are tears that help replace the fat layer of the tear film. You can find many good options at the drugstore or any place they sell artificial tears. Since you will be using the tears very frequently, you should only use preservative-free tears until your doctor tells you to decrease to four times a day or less. Hope this helps! READ MORE
Normal intraocular pressure should be between 10 - 22mmHg. The thickness of the cornea (the clear circle in the front of the eye) affects the pressure reading, so this should also be measured to get an accurate reading. I hope this info helps. READ MORE
The cost of laser vision correction varies, depending upon the type of technology and level of correction needed. When you see ultra low prices advertised, it's not real - the fine print indicates those prices are really for people who don't need or would likely not even qualify for a procedure. The average real price for laser vision correction, with the latest technology by a reputable physician is around $2000/eye - a little more or less, depending upon the level of correction. This includes follow-up care, which is very important, as well as some type of touch-up policy for the future. I hope this helps. Now days, the safety and precision of laser vision correction is amazing - you should get it done and enjoy the freedom of waking up each morning with clear vision! READ MORE
How often you should use the drops depends upon the reason you have dry eyes and they type of drops your are using. Therefore, it's a complicated question. If you are finding you must use the drops more than every 2 - 3 hours during the colder winter months, when the humidity is quite low, you should see your ophthalmologist to determine a better solution than just using drops, or possibly changing the type of drops you are using. Unfortunately, I can't be more specific, since the underlying reason for your dry eyes is very important to the answer. READ MORE
A 3yo with itchy, watery eyes is most likely suffering from an allergy of some sort. However, it could be other things, like a tear duct drain blockage or some sort of infection. The best option is to bring your child to a pediatric ophthalmologist to assess the problem. At that age, it's also good to assess the vision and just be sure the eyes are developing normally.

In general, you should not remove cataracts until you are unable to do the activities you want to do comfortably, despite wearing glasses or contact lenses. You are very young to have cataracts, but I've seen people like you before. If your every day activities are unaffected, and your night vision for driving is okay, you should just wait. The intraocular lenses that are used to replace your natural lens are very good today, as are the surgical techniques, but in time they'll get even better; so, if you don't have a problem today, just wait, and take advantage of better technology in the future.

-1.25 is a lower prescription than -1.75, so you would think that your visual ability has improved. However, it's more likely that the -1.75 was an over-correction and you were actually -1.25 all along. READ MORE

You will need a driver to take you home after LASIK, but you will likely be seeing well enough to drive the next day. READ MORE
A small, springy instrument called a lid speculum is used to keep your lids from blinking or closing. It doesn't hurt; you will feel pressure on your lids, but not pain. During the procedure, you will be asked to focus on a light above you, but small movements are normal, and will be automatically and rapidly tracked by the laser itself. Don't worry or stress yourself out - the procedure will be very fast and will not hurt. Within a very short time, you will notice a big improvement in your vision and will be very glad you had it done - you will wonder why you didn't do it sooner! Nancy A. Tanchel, M.D. READ MORE
LASIK is absolutely a great option for those with astigmatism. Your surgeon will review your eye maps and the exam findings and if your astigmatism is a regular astigmatism and your eyes are healthy, you will do great with a laser treatment. Frequently, laser vision correction will make your vision even better than glasses or contact lenses, since the correction is placed directly onto your eyes, so eye movement will not have any effect on your vision, as it can with glasses and contacts. You will really enjoy your vision without astigmatism, so definitely move forward and get the procedure - you will be really happy. READ MORE
Yes, excessive use of computer screens can cause dry eyes. Even though you don't consciously perceive it, the computer screens are flashing on and off at a very high rate. It is believed that your brain misinterprets this flash to assume your eyes blinked. Blinking is how we move tears over the eyes and keep the surface moisturized. As a consequence, your natural blinking rate is diminished, allowing your eyes to dry out. READ MORE
It may be something simple, related to dry eyes or something else like eye rubbing. However, it also may be a sign of a weakness of the corneal tissue - a problem called keratoconus. Hopefully, it's not anything serious, however, you should see an ophthalmologist soon, to assess what is happening and get the appropriate treatment, so your vision stabilizes. READ MORE
The vision may be different in your right eye due to astigmatism, or another reason. Astigmatism just means that one axis of your cornea has a different curvature than the opposite axis. That means, essentially, the eye is slightly football shaped, rather than basketball shaped. There can be many reasons you have astigmatism; it can be normal for you, or it can be part of a more complicated issue. You will need an eye exam to determine what's happening. Astigmatism can be easily corrected with LASIK, PRK or other procedures in most cases. However, you will need an exam to determine if that is a good option for you. Hopefully, this information is helpful. READ MORE
