Farsighted patients can focus on more distant objects, but not images that are close at hand. If you’re nearsighted, you can see clear images of near objects but things far away are blurry. Both hyperopia and myopia can be treated with several laser and non-laser surgical treatments, as well as non-surgical treatment options like glasses and contact lenses.
If you’re nearsighted, you can see clear images of near objects but things far away are blurry. Unlike hyperopia, which is usually present from birth or a very young age, myopia can occur gradually and become worse over time. Most people notice their nearsightedness when trying to read objects at a distance, such a wall clocks or traffic signs, and having to squint to get a better view. Myopia is also caused by a refractor error, in which the cornea is curved to steeply, or the eye is longer than usual.
Presbyopia is a natural part of the aging process and affects everyone, usually becoming noticeable as people enter their 40s. The eyes’ lenses lose elasticity, resulting in a slow decrease in the ability of the eye to focus on nearby objects. This is why you may need to hold reading material further away for it to become clear.
There are several types of astigmatism, including regular, mixed and irregular. In all cases, astigmatism makes it difficult to see fine details, either close-up or from a distance. Currently, lasers surgery can treat both regular and mixed astigmatism. Recent advances in technology now allow for the therapeutic treatment of induced irregular astigmatism, and this application may be expanded to include all types of irregular astigmatism. Patients with astigmatism should discuss their options with their eye care specialist.
Your eye is much like a camera – with a lens that focuses objects on the retina (film). The information recorded on the retina is sent to the brain, creating a picture. As we grow older, the natural crystal clear lens can become cloudy, causing blurred or foggy vision, light and/or glare sensitivity, problems identifying colors, and problems seeing up close and at a distance. This condition is called a cataract.
Fuch’s Corneal Dystrophy
Fuch’s Corneal Dystrophy (FCD) affects the endothelium layer of the cornea. It is a degenerative disease most often found in the elderly that causes the cornea to swell, resulting in sensitivity to light, worsening glare, decreased/blurred vision and sometimes pain in the eye. Treatment depends on how severe FCD is, but can include medication and corneal transplant surgeries such as DSEK, DMEK, and PKP.
Glaucoma is a disease of eye that causes the pressure inside the eye to rise. This can damage the optic nerve and cause blind spots in vision. Because this happens slowly and there is no pain, a patient can be totally unaware that there is a vision threatening problem.
Glaucoma cannot be cured, nor can lost vision be replaced or regenerated. However, further visual damage can be prevented by special eye drops, medication, surgery and laser surgery.
Macular degeneration is a deterioration of the central portion of the retina that causes poor central vision, and is the leading cause of impaired reading or detailed vision. Although macular degeneration causes distortion of central and color vision, side vision is not affected. Macular degeneration is often a natural result of the aging process and is most common in people over 60, but can appear as early as age 40. Occasionally, macular degeneration is caused by injury, infection, or inflammation. The disease may also be hereditary.
Diabetic retinopathy is a complication of diabetes involving the blood vessels that nourish the retina of the eye, and the leading cause of blindness among adults. Approximately 25% of current diabetics have some form of the disease. Left untreated, diabetic retinopathy can result in severe visual loss, including blindness. Since there is no pain or other external symptoms, changes in the retina can go unnoticed unless detected by an eye examination by an eye specialist. All people diagnosed with diabetes are at risk.
Flashes and Floaters
Small specks, spots and flashes of light in the field of vision are called flashes and floaters. Caused by changes in the fluid of the eye, flashes and floaters are generally not cause for concern. Flashes can also occur with migraine headaches.
In some cases, floaters and flashes may be the symptoms of a more serious eye problem, such as retinal detachment. The retina tears as the internal eye fluid shrinks and pulls away from the retina, causing bleeding that appears as a new set of floaters. Retinal tears require immediate medical attention to prevent retinal detachment which could result in partial or total loss of vision.
Dry Eye Syndrome
Our desert climate is one cause of DES. Others include lack of adequate tear production, hormonal change, side effect of medication, contact lens wear or insufficient blinking. Symptoms include chronic dryness, scratching and burning in your eyes, possible “foreign body sensation” and oddly enough, can include excessive tearing.
Treatment can include artificial tears, prescription eye drops and a simple office procedure called Punctal Plug Occlusion during which temporary or permanent silicone plugs can be inserted in the lacrimal (tear) drainage ducts in your eyelids to keep tears on your eye from draining away as quickly.
Salzmann’s Nodular Degeneration
Salzmann’s Nodular Degeneration (SND) is a rare but serious disease that progresses slowly. Patients with SND may have sensitivity to light, blurry vision, watery eyes, and other symptoms due to nodular lesions on the Bowman’s layer of the cornea. They may also often feel like there is a foreign body in their eye. These nodular lesions can be removed with surgery.
Refraction is the name of an eye test and a physician interpretation to produce a valid prescription for your glasses. This is a non-covered service for Medicare and most medical insurance companies.
If you need a new prescription for new eyeglasses during your visit there is a $55.00 fee for this service beyond what your insurance will cover. We request that you pay this fee at the time of your visit.
Eyeglass prescriptions typically expire after one year.
The LASIK procedure (also known as laser vision correction or refractive surgery) permanently reshapes the cornea – the outer window of the eye – so that the light focuses more precisely on the retina. LASIK reduces or eliminates conditions like near or farsightedness and astigmatism. The computer-guided Excimer Laser creates extremely accurate, intense pulses of light that vaporize cells, leaving the surrounding tissue untouched.
Descemet Membrane Endothelial Keratoplasty
Descemet Membrane Endothelial Keratoplasty (DMEK) is a procedure that removes the damaged Descemet membrane and endothelium from the eye. This unhealthy tissue is then replaced with healthy donor tissue. DMEK is for patients who have corneal diseases such as Fuch’s Dystrophy, Iridocorneal Endothelial Syndrome (ICE) and Posterior Polymorphous Corneal Dystrophy (PPCD).
Descemet Stripping Endothelial Keratoplasty
Descemet Stripping Endothelial Keratoplasty (DSEK) is a corneal transplant procedure. The damaged, small cell layer of the cornea is removed and replaced with donor tissue. DSEK is a good solution for patients with Fuch’s Corneal Dystrophy (FCD) and Bullous Keratopathy.
Penetrating Keratoplasty (PKP) is a procedure to remove a circular portion of the damaged cornea, which is replaced with full-thickness, clear cornea from a donor. This procedure is used in patients with severe corneal scarring, corneal infections and rarely in patients with Fuch’s Corneal Dystrophy (FCD). The recovery time for PKP is longer than for procedures such as DSEK and DMEK.
For those who may not be good candidates for laser vision correction, our specialists also offer clear lens surgery as an option. Using specialized tools, we are able to get the precise measurements of a patient’s eye and replace the human eye lens with an artificial lens that can focus light properly. This relatively minimally invasive procedure produces great results, with close to 90% of patients—whether they’re nearsighted, farsighted, or suffer from astigmatism—having the ability to drive without glasses following the extraction, and the remainder needing only a small follow-up correction.
