Pachymetry - Very Cool Stuff!

The optometrist will often have a patient return to the office for a special test called pachymety. This instrument using ultrasound technology will determine the central cornea thickness. This measurement is important in evaluating the intraocular pressure (IOP) for a patient who may be a glaucoma suspect. A thicker cornea results in an IOP reading for a patient that is higher than the actual pressure reading, whereas a thinner cornea will have an IOP reading lower than actual. A correction or adjustment is then applied to the IOP measurement to give the optometrist a more true reading. Pachymetry has other clinical uses involving the cornea. The thickness measurement is needed to determine if a patient is a suitable candidate for laser refractive correction or surgery. It also has a role in measuring corneal swelling from contact lens wear or from corneal disease.

Contact Lenses for BiFocals!

Many people feel that once they need a bifocal, they are unable to wear contact lenses. This is not true. In fact there are several options available. A person can wear two contact lenses for distance vision and then wear over-the-counter reading glasses over the contact lenses when reading. Another option is called monovision. In this method, a person wears a contact lenses that focuses them at distance in one eye and another contact lens that focuses them at near in the other eye. The brain learns to ignore the blurry eye not being used. The third option is multifocal contact lenses. At one point these were not very successful, however they are much better now and have a high success rate. These contact lenses let the patient view distance and near out of both eyes without any glasses.

Your Eyes on Steroids! (Hint: it won't make your eyes bulky)

Many of our patients have been placed on medications by their family doctor that have adverse reactions upon our eyes. One group of these medications, steroids, are often used in treating conditions as arthritis, some autoimmune diseases such as systemic lupus, and respiratory conditions as asthma. The two most common side effects are cataracts and increased intraocular pressure.

The ocular side effects of steroids are related to the method or route of administration. There is a strong association between inhaled steroids and a type of cataract called posterior subcapsular cataract or PSC. Patients on long-term rather than short term use of steroids such as prednisone, are at higher risk for this type of cataract formation. Increased intraocular pressures provides the patient with a risk factor for possible glaucoma development. Due to these two adverse effects of steroids, the patient should have a dilated and slit lamp examination of the eyes every 6 to 12 months. Both of these important tests are part of a comprehensive eye exam at any of our Rinkov Eyecare locations.

Morning Eye Irritation is Irritating!

Often patients will report waking in the morning with severe eye irritation, watering, blur, and light sensitivity. These symptoms will often dissipate after a few hours of being awake. One thing this can be due to is a condition called #lagophthalmos. This is a condition in which the patient sleeps with their eyes partially open. Therefore during the night the eyes dry out and the patient awakens to severe discomfort. A few ways to combat this problem are to tape the eyelids shut with medical tape before bed, or use a thick artificial tear ointment immediately before going to bed. This ointment protects the eye's surface from drying out due to environmental exposure. The only real way to tell if you suffer from this condition is to have someone look at your eyes while you are sleeping. The first step is to call your Optometrist to see if lagophthalmos may be the cause of your morning eye irritation.

The Lens of the Eye

The lens of the eye or often called the natural lens, is a transparent bioconvex structure positioned behind the pupil. The lens and the corneal are the predominate refracting surfaces of the eye.....that is they provide the power or our prescription in order to see. The internal structure of the lens allows for a large amount of elasticity to thicken or thin its size. This property of elasticity provides the eye the increased power to do most near tasks, as in reading. However, as we age, the lens gradually loses this elasticity, so by the age of 45 years, we have to supplement this loss with reading glasses. This decrease of elasticity or power is called presbyopia. Any loss in the transparency of the lens , which can greatly reduce our vision, is called an opacity or a cataract. We as optometrists during a normal comprehensive vision examination will evaluate the elasticity and transparency of the lens.

Winter Sunglasses are Must Have!

Now that we are in the winter months, many people don't think about sunglasses. They consider them summertime eyewear. However, sunglasses may be even more important in the winter. When snow is on the ground, sunlight and therefore UV radiation reflects off of it into our eyes.This can be worse than in the summer, when sunlight only comes from above. What can be particularly helpful, is a polarized sunglass lens, as these will help cut the blinding glare off the snow's surface.

My Eyes are Changing!

Many people around the age of forty go to the eye doctor after noticing that their near vision is blurry, often requiring them to push their reading material farther away. The is caused by a natural aging change called presbyopia. Presbyopia causes the natural crystalline lens within the eye to slowly harden. Until now, the lens is flexible and changes shape, with the help of the muscles that surround it, to allow for focusing at different focal distances. As the lens hardens, the focal distance becomes set at distance instead of near. This happens gradually from about age forty to fifty five. During this time is when people will notice a benefit from reading glasses or bifocals.
