Question 1

What's the difference between an ophthalmologist, optometrist, and optician?

Accepted Answer

Ophthalmologists are medical doctors (MD or DO) who provide comprehensive medical and surgical eye care, treat all eye diseases, and perform surgery. Optometrists (OD) are doctors of optometry who perform eye exams, prescribe glasses and contacts, and can diagnose and treat some eye conditions with medications (scope varies by state), but don't perform surgery. Opticians fit and dispense eyeglasses and contact lenses based on prescriptions but don't examine eyes or diagnose conditions. For eye disease or surgery, you need an ophthalmologist.

Question 2

How often should I have an eye exam?

Accepted Answer

Recommended frequency depends on age and risk factors. Adults 18-60 with no risk factors should have comprehensive eye exams every 2 years. Adults over 60 should have annual exams due to increased risk of cataracts, glaucoma, and macular degeneration. People with diabetes, family history of eye disease, or existing eye conditions need annual or more frequent exams. Children should have exams at 6 months, 3 years, before first grade, and then every 1-2 years. Your eye doctor will recommend appropriate intervals based on your situation.

Question 3

Is cataract surgery safe and what's the recovery like?

Accepted Answer

Cataract surgery is one of the safest and most successful surgeries performed, with over 95% success rate. It's outpatient surgery taking 15-20 minutes under local anesthesia. Most patients experience minimal discomfort and improved vision within days. You'll use antibiotic and anti-inflammatory eye drops for a few weeks. Avoid rubbing your eye, swimming, and heavy lifting for 1-2 weeks. Most people return to normal activities within days. Serious complications like infection or retinal detachment occur in less than 1% of cases. Vision continues improving over several weeks.

Question 4

Am I a candidate for LASIK or refractive surgery?

Accepted Answer

Good LASIK candidates are: over 18 years old (preferably over 21), have stable vision prescription for at least 1 year, have healthy corneas with adequate thickness, have moderate myopia (nearsightedness), hyperopia (farsightedness), or astigmatism within treatable range, and have realistic expectations. You're likely NOT a candidate if you have: thin corneas, keratoconus, severe dry eye, unstable vision, certain autoimmune diseases, or are pregnant. A comprehensive evaluation by a refractive surgeon with corneal topography and pachymetry determines candidacy. Alternatives like PRK, SMILE, or ICL exist for those not suitable for LASIK.

Question 5

What should I do if I experience sudden vision loss?

Accepted Answer

Sudden vision loss is a medical emergency requiring immediate attention. Go to the emergency room or call your ophthalmologist immediately for: sudden vision loss in one or both eyes, sudden onset of many floaters or flashing lights, curtain or shadow over your vision, sudden eye pain with vision changes, or sudden double vision. Conditions like retinal detachment, retinal artery or vein occlusion, and vitreous hemorrhage need urgent treatment to prevent permanent vision loss. For stroke-like symptoms with vision changes, call 911. 'Time is vision' - prompt treatment can save sight.

Question 6

Will I need glasses after cataract surgery?

Accepted Answer

It depends on the type of intraocular lens (IOL) implanted. Standard monofocal IOLs correct vision at one distance (usually far), so you'll likely need reading glasses. Premium IOLs offer more options: multifocal IOLs reduce dependence on glasses for both distance and near vision (though some patients still need glasses for certain tasks), toric IOLs correct astigmatism, and extended depth of focus IOLs provide good intermediate and distance vision. Discuss goals and expectations with your surgeon. Most people are very satisfied with their vision after cataract surgery, whether or not they need glasses.

Question 7

Can glaucoma be cured?

Accepted Answer

Glaucoma cannot be cured, but it can be controlled to prevent vision loss. The goal is lowering intraocular pressure to slow or stop optic nerve damage. Treatment includes: eye drops (first line - several classes available), laser trabeculoplasty, and glaucoma surgery (trabeculectomy, tube shunts, MIGS). Vision already lost to glaucoma cannot be recovered, which is why early detection through regular eye exams is critical. With treatment, most people maintain useful vision throughout life. Adherence to eye drops and regular monitoring are essential for success.

Question 8

What causes floaters and when should I be concerned?

Accepted Answer

Floaters are tiny clumps in the vitreous gel inside your eye casting shadows on your retina. They're common and usually benign, especially with age as vitreous liquefies. However, seek urgent care if you experience: sudden increase in floaters, flashing lights, shadow or curtain over your vision, or sudden vision decrease - these may indicate retinal tear or detachment requiring prompt treatment. Gradual increase in floaters over years is usually normal aging. Most floaters become less bothersome over time as your brain adapts. Rarely, floaters can be treated with laser vitreolysis or vitrectomy if severely bothersome.

Question 9

How can I prevent or slow macular degeneration?

Accepted Answer

While you can't completely prevent AMD, you can reduce risk and slow progression: don't smoke (biggest risk factor you can control), eat diet rich in leafy greens and fish (omega-3 fatty acids), take AREDS2 vitamins if you have intermediate AMD or advanced AMD in one eye (specific formulation of antioxidants and zinc), maintain healthy blood pressure and cholesterol, protect eyes from UV light with sunglasses, maintain healthy weight, and get regular exercise. Monitor vision with Amsler grid at home to detect changes early. If you have wet AMD, prompt anti-VEGF injections can preserve vision.

Question 10

Do I need to see an ophthalmologist if I have diabetes?

Accepted Answer

Yes, all people with diabetes need regular comprehensive dilated eye exams by an ophthalmologist or optometrist. For type 1 diabetes, have first exam within 5 years of diagnosis, then annually. For type 2 diabetes, have exam at time of diagnosis, then annually (some low-risk patients may extend to every 2 years per doctor recommendation). Diabetic retinopathy often has no symptoms until advanced, so regular screening is essential for early detection and treatment. Pregnancy with diabetes requires exams each trimester. Good blood sugar control, blood pressure control, and regular eye exams can prevent or delay diabetic eye disease.
