Q: What are multifocal lens implants?
A: Multifocal lens implants are often used in cataract surgery to reduce the dependency upon glasses for both distance and near vision after the surgery is completed. As with other medical technology, not everyone will be a good candidate for this type of surgical implant. Patients with corneal scarring or significant astigmatism, as well as surgical candidates with eye diseases such as diabetic retinopathy, glaucoma and macular degeneration, may not receive the full benefit from these lenses. Your eye care professional can help determine if this lens implant option is right for you.
Q: How does high blood pressure affect vision?
A: High blood pressure alone does not usually affect vision directly, however hypertension is a known risk factor in the onset and/or progression of other eye disease, such as glaucoma, diabetic retinopathy, and macular degeneration, as well as blocked veins and arteries in the retina or nerves of the eye that can severely affect vision. In malignant hypertension, very high blood pressure can damage organs, and may cause swelling of the macula and acute loss of vision.
Q: What exactly is glaucoma?
A: Glaucoma is a condition in which the eye's intraocular pressure (IOP) is too high. This means that your eye has too much aqueous humor in it, either because it produced too much, or because it's not draining properly. Other symptoms are optic nerve damage and vision loss. Glaucoma is a silent disease that robs the patient of their peripheral vision. Early detection is very important.
Q: What is Keratoconus?
A: Keratoconus is a disorder of the anterior surface of the eye (the cornea). In simple terms, the cornea becomes thinner causing it to bulge from its normal round shape to a cone-like shape. This bulging interferes with a person's vision and can severely affect the way they see the world, making simple tasks like reading, watching TV or driving very difficult. The distortion caused by keratoconus has been compared to viewing a street sign through your car windshield during a driving rainstorm.
Q: Am I a good candidate for refractive surgery?
A: Patients who are at least 18 years of age, have healthy eyes that are free from retinal problems, corneal scars, and any eye diseases are generally suitable. Many patients who are nearsighted, farsighted or have astigmatism are potential candidates. We will also discuss your lifestyle needs to help you decide if LASIK is the best alternative for you. If you would like to schedule a free LASIK consultation, please contact our office.
Q: What exactly is macular degeneration?
A: Macular degeneration is a condition in which the eye's macula breaks down, causing a gradual or sudden loss of central vision. There are two forms called wet and dry. Patients need a detailed retinal eye exam to determine if they have this condition.
Q: What are the signs of a retinal detachment?
A: A detachment of the retina may be preceded by flashes of light, increased “floater” spots in the vision or areas of “wavy, distorted vision”, etc. Most retinal detachments are painless. They can happen as a result of recent or past trauma such as falls, automobile accidents or other types of head injury. In some instances, people may be at risk for retinal detachments based on family history and increased nearsightedness. If you experience any of the above symptoms, consult your eye care professional as soon as possible.
Q: What is snow blindness?
A: Snow blindness is a form of photokeratitis, meaning a burn of the cornea caused by UV light exposure. The UV light is reflected off of the snow; and without sunglasses or other eye protection, it can lead to a painful injury. Photokeratitis is more common at higher altitudes due to the thinner atmosphere. A similar injury can result from welders, water reflections or tanning beds. Don’t forget your sunglasses on your powder days!
