Helpful eye care tips, vision education, and modern optometry insights from OPTISM in Tampa, FL.

Refractive lens exchange uses the same basic technique as cataract surgery but removes a clear natural lens to reduce dependence on glasses before a significant cataract develops.

SMILE is a minimally invasive laser vision procedure that removes a thin piece of corneal tissue through a small incision. Learn how it differs from LASIK and PRK.

LASIK can reduce dependence on glasses and contact lenses by reshaping the cornea. Learn how the procedure works, what recovery is like, and why a complete eye evaluation is essential before surgery.

Modern cataract surgery can do more than remove a cloudy lens. Premium intraocular lenses may also correct astigmatism or provide a broader range of vision, but every design has tradeoffs.

Test your knowledge of the different types of amblyopia with this 6-question quiz covering refractive, strabismic, deprivation, mixed-mechanism, and reverse amblyopia, plus common treatment approaches.

PRK offers laser vision correction without creating a corneal flap. Although healing takes longer than LASIK, it may be preferred for certain corneas, occupations, and active lifestyles.

Giant cell arteritis, also called temporal arteritis, is a serious inflammatory condition that can cause headaches, jaw pain, scalp tenderness, and sudden vision loss. Learn the warning signs and why early treatment is critical.

A pigment epithelial detachment, or PED, is a finding on retinal imaging, while central serous retinopathy is a disease process that can cause fluid under the retina. Here’s how they compare.

Central serous retinopathy occurs when fluid builds up under the retina, often causing blurry or distorted central vision. Learn how stress, cortisol, steroid use, and Type A personality traits may contribute to this condition.

Super glue in the eye can cause the eyelids or lashes to stick together and may scratch the cornea. Patients should avoid forcing the eye open, avoid acetone or household solvents, rinse gently if possible, and seek prompt eye care.

Before LASIK, radial keratotomy used spoke-like corneal incisions to reduce nearsightedness. Although many patients initially achieved clearer distance vision, RK can cause prescription changes, irregular astigmatism, glare, and fluctuating vision decades later.

An epiretinal membrane, also called a macular pucker, is a thin layer of scar-like tissue that forms over the macula and can cause blurry or distorted central vision. Learn how eye doctors detect it, monitor it, and when treatment may be needed.

Multiple sclerosis can affect the eyes by causing optic neuritis, double vision, shaky vision, poor eye tracking, and trouble with color or contrast. Learn the early signs and when to schedule an eye exam.

A rapidly growing red bump on your eye may be a pyogenic granuloma. Discover why these benign vascular growths develop, how eye doctors diagnose them, and which treatments can help.

Vision is more than light entering the eye. It is a coordinated process that begins with image formation, continues through phototransduction and retinal signal processing, and ends with interpretation in the visual cortex. This clinician-friendly guide reviews how the cornea and lens focus light onto the retina, how rods and cones convert photons into neural signals, how inner retinal circuitry refines the message, and how the optic nerve, chiasm, LGN, optic radiations, and

Thinking about LASIK but still wearing contact lenses every day? Overwearing contacts can temporarily distort the cornea, worsen dry eye, and make LASIK measurements less reliable. Before moving forward with laser vision correction, your eye doctor needs to make sure your cornea is clear, healthy, and stable.

Different lens tint colors can improve comfort, reduce glare, and enhance contrast for specific activities like driving, golf, fishing, sports, and computer work. Here’s how to choose the best tint for your lifestyle

A quick-reference guide for optometrists covering orbital blowout fracture symptoms, trauma exam essentials, entrapment warning signs, CT findings, red flags, and urgent referral decisions.

A practical guide for optometrists on recognizing orbital blowout fractures, evaluating diplopia and motility restriction, identifying entrapment and emergency red flags, and knowing when urgent referral is needed.

Why do some babies’ and young children’s eyes turn inward? Learn how farsightedness, focusing effort, and accommodative esotropia are connected, what signs parents may notice, and how glasses can help improve eye alignment and support healthy visual development.
