Eye Exams for Adults

by Siems Lasik on August 18, 2013

Receiving routine and comprehensive adult eye exams is critical for maintaining healthy vision and identifying and treating various diseases or disorders. Adults in Las Vegas should receive eye exams every other year and every year after turning sixty years of age. These exams are crucial for detecting cataracts, glaucoma, diabetic retinopathy, and macular degeneration. Exams are particularly important for people that have risk factors or a family history of eye problems. Dr. Jon L. Siems has performed routine adult exams in Las Vegas since 2001, and is one of the most experienced Ophthalmologists in Nevada.

What to do before your eye exam

It is very important for patients to be prepared.  The first step is the initial phone call to an experienced optometrist of the patients choosing to schedule an appointment.  Patients should be prepared to describe any vision problems.

Patients should create a list of questions they have or any specific issues with their vision. They should also list all current medications along with noting their family history regarding eye health.

If the patient wears glasses or contact lenses, they should bring them to the appointment. It is also a good idea to bring a dark pair of sunglasses in case the pupils are dilated.  The patient may be advised to plan to have someone take them home if needed.

What to expect during an eye exam

A thorough medical and vision history is generally requested as the first step in exams for adults, followed by a 30-60 minute evaluation of their vision and their overall eye health. Tests that are typically administered during a routine adult exam are listed as the following:

Test for movement of eye muscles:

This test is performed by observing the patient’s ability to visually follow a moving light that continually changes direction.  This test identifies control and muscle strength.

Test your eyes for visual acuity:

This test requires the patient to cover one eye at a time and then read the letters they see on the chart in front of them.  They are asked to read as far down as possible to the smallest letters they are able to see clearly.

Test for reaction of pupils and the exterior:

This test allows the optometrist to observe how the patient’s pupils react to light and to nearby objects. The exterior of each eye is also observed, including the eyelid position and the white part of the eye.

Eye cover test:

This test determines whether the patient’s eyes work well together by covering and uncovering each one as the patient stares at objects of varying distances.

Retinoscopy:

This test can be conducted either by shining a light in to the patient’s eyes or by having them look through a machine with flip lenses while the optometrist observes how the light is reflecting off each of their eyes.

Test for glaucoma:

This tests the fluid pressure of the eye and is administered by blowing a puff of air using a special instrument used after numbing drops are administered.

Refraction test:

This test is only used if the patient has or needs corrective lenses. It is typically administered by having the patient identify the clearer of two slides that are continuously flipped back and forth.

Retinal eye exam:

This test involves dilating the pupils and using an ophthalmoscope to examine the back of the eyes, including the retina, vitreous, retinal blood vessels, and the head of the optic nerve.

Slit lamp test:

This test uses a slit lamp to light up and magnify the front of the eye in order to detect a number of disorders and diseases by observing the lens, cornea, iris, and anterior chamber.

Test of the visual field:

This exam tests the patients peripheral vision.

Pachymetry exam:

By using ultrasound, the optometrist is able to get a baseline reading of the corneal thickness used for future comparison for patients possibly needing corneal surgery.

Dilating the pupils in your eyes:

This is done by enlarging the pupils by using special drops.  This allows the optometrist to fully examine the inside of the eye using various lights and instruments.  It takes about twenty to thirty minutes for the pupils to dilate and may cause the eyes to be more sensitive to light or cause blurry vision.  This is where bringing sunglasses to the exam may come in handy.

Tips for finding an Optometrist

  • Family doctor referrals
  • Friends and family referrals

Cataract and Refractive Surgery

by Siems Lasik on August 10, 2013

Refractive cataract surgery is a newer process that uses refractive technology to correct the long-standing issues of cataract development on the eyes. Not too long ago, cataract surgery was used to remove the cloudiness that appeared in the lenses of patients, and after the completion of the procedure, to continue enjoying good vision, the patient would have to depend upon the use of corrective lens alternatives such as eyeglasses, contact lenses, or reading glasses to assist in their vision maintenance. The newer process of combining refractive surgery with cataract repair highly increases the odds of patients post-surgery not having to be solely dependent upon vision corrective measures. Prior to choosing refractive cataract surgery as a viable option for vision correction, it is important for the patient to consult their eye doctor, usually an ophthalmologist to determine whether the procedure is the best route to clear vision.

The Original Procedure

Normal cataract surgery is one of the most common types of procedures performed on patients after consulting with their eye doctor or ophthalmologist. The outcome of the procedure is dependent upon the skill set of the surgeon, and generally the more procedures that surgeon has completed during their career, the more efficient they become in successfully helping their patient. The eye generally heals itself from the multiple incisions made on the lens to remove the cataract. Once the cloudy portion of the lens is removed, an IOL or intra-ocular lens is placed where the cloudy lens once was.

The New Option

With the newer, more advanced refractive version of the procedure, the surgeon uses a three-dimension view of the eye to make a more accurate, crisp incision into the eye called an optical coherence tomography. This helps ensure that regardless of surgeon experience, the procedure is completed easily and accurately to solve vision issues such as cataracts.

Costs of the New Option

For surgeons, the purchase of the refractive devise for this procedure, it can cost upwards of half a million dollars. This will automatically make the cost of the procedure more than the standard, older procedure that has been used for years. Most of the cost of the new procedure will not be covered by medical insurance or by Medicaid and Medicare. This is another reason why it is so very important to meet with an eye doctor such as an ophthalmologist to ensure that the newer procedure is best suited not only from a medical standpoint but a financial standpoint for the patient as well.
