Dr. Anthony Roberts, an eye health specialist, provides a variety of treatments for common eye conditions. Additionally, for patients who qualify for the procedure, Dr. Anthony Roberts performs Lasik surgery.
For many individuals, Lasik surgery, a type of surgery that uses a laser to correct vision, can provide good results. However, certain individuals are not good candidates. Doctors look at a number of factors when determining a person’s suitability.
To start, the person should be over 18 years of age and in good health overall. This includes eye health, as having conditions such as glaucoma, herpes zoster, and others can disqualify a person. People who have ongoing issues with eye dryness and whose vision is unstable should not get the procedure, and pregnant and nursing women should wait for a period of time as advised by their doctor. This is because hormones during this time can affect vision.
Other factors doctors evaluate include the thickness of the patient’s corneas, as people who have corneas less than around 0.5 millimeters thick shouldn’t get the surgery. The doctor must deem the person’s farsightedness, nearsightedness, or astigmatism to be treatable through the procedure as well. An eye doctor can check for these and other important factors during a consultative visit.
Dr. Anthony Roberts is a Rockville, Maryland, physician who leads Shady Grove Ophthalmology and offers LASIK treatments. Experienced in employing advanced technologies in vision correction, Dr. Anthony Roberts undertakes the majority of LASIK procedures using the femtosecond laser, which offers a host of distinct advantages over other techniques.
Femtosecond laser systems are infrared and were first developed for ophthalmic use in the 1990s. They employ an ultrashort pulse of light that is achieved through passive mode locking. Finely tuned application of these ultrashort pulses results in a quickly expanding cloud of ionized molecules and free electrons, like an acoustic shock wave.
This is used to perform a variety of procedures, including corneal refractive surgery, particularly for correcting presbyopia and implanting intrastromal corneal ring segments. Femtosecond lasers are also used in LASIK procedures to cleave the cornea over the pupil and create what is known as the “LASIK flap.” Advantages include the reduced incidence of flap complications and greater physician control in determining variables such as flap thickness and diameter.
Dr. Anthony Roberts, founding physician at Shady Grove Ophthalmology, treats patients with a wide variety of vision difficulties. Dr. Anthony Roberts offers Lasik as well as nonsurgical therapies for myopia and is extensively experienced in the treatment of presbyopia.
Presbyopia, or farsightedness, is traditionally a condition of middle and older age. In a healthy and young eye, the ciliary body adjusts the thickness of the crystalline lens so that a person can focus on an object close to the body. Around the age of 40, however, the ciliary body muscle begins to break down and the crystalline lens begins to harden.
Lately, however, ophthalmologists and opticians in Japan have begun to notice an increase in presbyopia symptoms among young adults. A recent survey suggests that while only 0.5 percent of individuals aged from the late teens to 34 reported such symptoms in 2012, more than 6.6 percent did so in 2013. Eye care professionals believe that this increase may be largely due to this population’s near-constant use of smartphones, which invite a sustained focus on a small screen.
Staring at a close object causes the ciliary body to stiffen, thus decreasing the ability of the eye to adjust when switching from near to far vision and back again. Known as adjustment tension, this process is most often temporary but may become permanent in more severe cases. Some ophthalmologists have responded to this trend by calling for a reduction in the extended use of mobile devices and an increased focus on personal eye care.
Dr. Anthony Roberts has worked as an eye physician at Shady Grove Ophthalmology in Rockville, Maryland, since 2002. In this position, Dr. Anthony Roberts addresses a number of eye conditions, such as myopia and dry eyes.
While a number of environmental factors can cause a person to experience dry eyes for a period of time, certain medical conditions can lead to a dryness in the eyes that does not dissipate until treated by an eye physician. The primary cause of dry eyes is a lack of tear production. Although some people might assume that tears are simply a mixture of water and salt, tears also contain important fatty oils and mucus that help the eyes maintain a smooth, clear texture. Tears also defend eyes against potential infections.
There are basically two causes of dry eyes. In certain cases, a person is incapable of producing enough tears. Officially known as keratoconjunctivitis, lack of tear production can be attributed to advanced age, medical conditions such as diabetes or vitamin A deficiency, and damage to the tear glands due to inflammation or radiation.
In other cases, a person might produce a sufficient amount of tears, but they may evaporate quicker than normal. These situations are often more temporary than instances of decreased tear production. For instance, wind or smoke in the air can cause tears to evaporate faster than normal, as can periods of intense concentration. However, conditions affecting the eyelids like ectropion and entropion can also lead to tear evaporation.
Dr. Anthony Roberts of Shady Grove Ophthalmology in Rockville, Maryland, has extensive experience in LASIK vision correction and photorefractive keratectomy (PRK), having performed more than 55,000 refractive procedures over his nearly two-decade career. At his practice, Dr. Anthony Roberts also administers treatments for cataracts.
Cataracts affect approximately 20.5 million people over the age of 40 and more than half the population of those 80 years old and up. The condition causes clouding of the lens, resulting in vision impairment, and develops from a buildup of protein that is compacted into the center of the lens as new lens cells form.
Cataracts can occur at any age. Babies can be born with the condition, known as congenital cataracts, because of an infection or injury caused while still in the womb. A traumatic injury to the eye or development of diabetes can also result in cataracts. Further, the condition can be brought on by smoking cigarettes, consuming mass quantities of alcohol, and/or living in polluted areas.
Dr. Anthony Roberts has extensive expertise in evaluating and treating eye conditions. In addition to providing patients with routine eye care, Dr. Anthony Roberts also performs LASIK surgery to address patients’ vision problems.
For many people, wearing glasses or contact lens has long been a part of life. However, with new surgical options, a doctor can fix many common vision problems. For those opting for LASIK, a doctor can provide details of the procedure and outline exactly what the patient should expect.
First, the doctor uses drops to numb the eye; as a result, the procedure is typically painless. The doctor will use a special surgical instrument to hold the patient’s eye open and make a flap on the cornea’s surface. At this point, the doctor will use the laser to make small modifications to the corneal shape in accordance with the patient’s particular prescription. After completing this stage, the doctor will then put the flap back in place. Once the procedure ends, the patient should then follow the doctor’s instructions for aftercare during the recovery period. For instance, the patient will need to use certain eye drops for a period of time after the surgery and return for follow-up visits.
Dr. Anthony Roberts heads Shady Grove Ophthalmology, a practice located in Rockville, Maryland. There, Dr. Anthony Roberts performs specialized procedures, such as LASIK, as well as provides routine eye examinations.
In order to keep the eyes healthy for the long term, you should get regular eye exams. During these sessions, the eye doctor will perform various tests that can highlight issues that might affect your eye health.
For instance, the doctor will often check how well you can see over distances by asking you to read lines of letters from a chart. He or she might also ask you to cover one eye at a time during certain tests in order to identify any potential issues with eye movement.
Other common tests include a visual examination of the eye itself to identify potential problems. Additionally, the doctor may look at parts of the back of the eye after dilating, or enlarging, the pupils with special eye drops. The eye examination may also include a test of the pressure inside the eye, which can alert the doctor of a potential risk for glaucoma.
