My Answers

What should avoid before LASIK?
You should avoid getting eyelash extensions or false lashes and be very diligent about cleaning your eyelids and lashes when washing your face. That will decrease the risk of post-op infection. READ MORE
Can your eyesight be fixed with laser surgery?
If your eyesight is poor due to myopia or astigmatism, LASIK, PRK, or SMILE are effective treatments. Other causes of reduced vision won't be solved with laser. READ MORE
How long does LASIK surgery last?
The changes made to your eye from LASIK are permanent, but the visual result will fluctuate. Many patients find themselves needing glasses for night driving after a few years and needing reading glasses starting in their early to mid 40s. Lens replacement will result in more stable vision, but is more invasive and expensive. READ MORE
How permanent is LASIK surgery?
LASIK is permanent, meaning the corneal tissue is altered forever. However, the correction of vision is not permanent. The lens inside the eye continues to grow layers of protein, changing its curvature and changing your refraction (the measurement of a glasses prescription.) Expect that LASIK will reduce your dependency on glasses, but not replace them forever. READ MORE
How do you relax sore eyes?
This would need to be answered with an eye exam- to determine if they are sore from lack of glasses (strain) or ocular surface disease. READ MORE
Should I wear sunglasses after LASIK surgery?
Yes, you should always wear sunglasses to prevent UV damage that causes cataracts, macular degeneration, and growths on the eyelids and eyeball itself. READ MORE
Can lazy eye go away?
A "lazy eye" or strabismus is a serious condition. Please get your daughter evaluated *this week*. When the eye is turned in or out, the brain isn't using it. This can be due to a higher prescription in that eye, a muscle imbalance, cataract, or other factors causing poor vision. By correcting an eye turn at a young age (before age 3) there is a high chance for normal neurological development. Correction for strabismus may be as simple as glasses, vision therapy, or surgery for cases of a large angle (very obvious eye turn.) READ MORE
Which vitamin supplement is best for eyesight?
Antioxidants in general are protective against cataracts, macular degeneration, and other aging-related conditions from UV light. These include Vitamins A, C, E and are found in leafy greens and berries- fruits and vegetables rich in colored pigments. READ MORE
How should I sleep after LASIK?
Your surgeon's office will probably give you eye shields to wear the first night. READ MORE
How do you know what strength reading glasses to get?
When you have an eye exam, the refraction measures this with precision. READ MORE
How can I fix myopia?
Myopia is best corrected with glasses, contact lenses, or ortho keratology. The only "fix" is surgery like Lasik, PRK, ICL, or Refractive Lens Exchange. These should only be considered once a patient has reached their early 20s and the surgeon deems the shape of the eye appropriate and conditions safe. READ MORE
Can presbyopia lead to blindness?
Presbyopia is corrected by reading glasses, progressives, bifocals, trifocals, or contact lenses. Surgically, it can be corrected by multifocal lens implants. This natural aging process doesn't lead to blindness, just the need for reading correction. READ MORE
Can you put eye drops in your eyes while wearing contacts?
Only certain eye drops will do well with contact lenses and their label will specifically mention "for contacts." Otherwise, they're to use without contact lenses to make sure they're effective and don't ruin your lenses. READ MORE
Can type 2 diabetics get Lasik eye surgery?
Yes, but you want to ensure your A1c is normal and glucose is stable so that your measurements are accurate. If not, wait until they are. READ MORE
Redness of eye won’t go away
It sounds like you need an exam with an optometrist or ophthalmologist to diagnose the problem and treat it. READ MORE
What helps eye pain after cataract surgery?
Your surgeon should have prescribed medicated eyedrops to prevent infection (an antibiotic) and calm inflammation and pain (a steroid and sometimes also an NSAID.) You should call your surgeon's office if you're experiencing pain. READ MORE
How often should you change contacts?
This depends upon the type of contact lens and how it was designed and FDA-approved. Daily disposable contact lenses should be discarded after wearing once and are the healthiest modality. READ MORE
Can you wear glasses for farsightedness all the time?
Yes, if the prescription was measured for distance viewing. READ MORE
How long do eye floaters usually last?
A lifetime- if they're the benign floaters which are strands of collagen in the vitreous which have clumped together. You need a dilated eye exam to determine the type of floaters and if treatment is needed. READ MORE
Should my eye hurt after wearing contacts?
No, your eye should not hurt. Either your contact lens doesn't fit properly or you have an infection. I would schedule an appointment with your optometrist or ophthalmologist today. READ MORE
