Post-LASIK Refraction and Pregnancy – Much Ado About Nothing?

Written by Dr. David Evans Last modified on August 23, 2018

During pregnancy, women experience a drastic shift in their hormonal balance that has a ripple effect throughout the body. The spike in hormones like progesterone, estrogen, prolactin, oxytocin and relaxin are all important for a healthy pregnancy, but these increased levels can also impact gastrointestinal processes, blood pressure, skin pigmentation and, you guessed it, ocular health. Due to refractive changes that often occur during pregnancy, most refractive surgeons advise against LASIK during pregnancy, instead suggesting women wait several months after giving birth before considering treatment. Women who have already undergone LASIK may then wonder if the changes in ocular health that can occur during and after pregnancy impact post-LASIK refraction. New research presented by John Kanellopoulos, MD, New York University Medical School, NY, and LaserVision.gr seems to throw cold water on any such concern. pregnancy-410x263.jpgThe Eyes and Pregnancy A number of studies have previously evaluated the correlation between pregnancy and ocular changes. Dry eye syndrome, decreased sensitivity of the cornea, increased corneal thickness and decreased intraocular pressure are a few of the side effects previously linked with pregnancy. These combination of changes can affect refractive error during pregnancy. But the question of refractive changes for post-LASIK patients is something of an open question. The current study involved 61 female patients from a single practice who had undergone LASIK prior to pregnancy to correct myopia and/or astigmatism, and had since giving birth. The average patient age was 28, and the average period of time that passed between LASIK surgery and pregnancy was 55 months. The study also weighed the various epithelial profiles of all patients using optical coherence tomography in order to obtain a more precise measure of spherical refraction. Although refractive error changes have previously been attributed in part to the hormonal shifts during pregnancy, the study found no such correlation with long term changes.  Dr. Kanellopoulos noted that “pregnancy does not appear to affect long-term post-LASIK refractive stability.” However he noted that there are few studies evaluating this aspect of pregnancy and ocular health, and suggested that further study could help confirm his findings. What This Means for You If you are considering LASIK but also planning on having children, and are concerned about how the latter may interfere with the former, then this study is good news. It suggests that women need not put off LASIK until after pregnancy and sacrifice their quality of vision in the short term out of a concern that a future pregnancy could impact the long-term quality of vision achieved with LASIK.  It is still a good idea not to have LASIK during pregnancy, but based on this study, treatment before pregnancy does not appear to pose any post-pregnancy problems. However, as Dr. Kanellopoulos clearly states, this is but one, relatively small-scale study, and further evaluation is needed to corroborate the findings. If you’re interested in LASIK and unsure whether or not the timing is right, or whether you are a good candidate for LASIK, I urge you to sit down with a qualified ophthalmologist to discuss your options in detail. If you’re looking for a LASIK surgeon, I’ve written previously about the best method for choosing the right surgeon for your needs.

Overuse of Contact Lenses

Image
How do make sure you aren’t overusing your lenses? Most people who have prescription eye glasses prefer wearing contact lenses. It’s not only comfortable but it also doesn’t alter your natural look. Though contact lenses are convenient they shouldn’t be used extensively. Overuse of contact lenses can cause serious damages to your eye. If you are not following the 18 hour week rule, then you could be overusing your contact lenses. In other words you must take out your contact lenses for at least 18 hours a week. Here are some symptoms which are indications that you are using you have your lenses on longer than you should, and you need to consult your eye doctor immediately: Pain and redness in the eye Itching when you remove your lenses Increased mucous secretion in the eye Decreased vision Photophobia or light sensitivity Tearing Inability to remove your lenses because they are stuck in the eye   Your eye needs direct oxygen to ‘breathe’ and remain healthy.

I Spy a Stye in Your Eye

Written by Dr. David Evans Last modified on August 6, 2018 What’s that small, red, pimple-like bump on your eyelid that’s causing so much discomfort? It’s probably a stye (sometimes referred to as a sty or hordeolum). Besides being difficult to say 5 times quickly, an eye stye is a type of localized infection that can occur along the base of your eyelashes or underneath your eyelid. Styes that form along the base of the eyelashes are called external styes. They typically occur as a result of an infected eyelash hair follicle and look like the type of pimple that occurs when your pores are clogged with dirt and oil. Styes that form inside the eyelid are called internal styes. Similar to external styes, they are caused by an infection of an oil-producing gland behind the eyelid rather than an eyelash hair follicle. Internal styes result in generalized swelling of the eyelid rather than forming a pimple-like bump. Stye Symptoms As a stye develops, you might begin to experience pain

Eyelash Extensions – Yay or Nay?

Image
What You Should Know Before Heading To The Salon. Eyelash extensions are individual lashes, made of a synthetic fiber such as nylon, which a professional aesthetician glues one by one to each of your top lashes. Using long, pointed tweezers, the tech brushes a single synthetic lash in a dab of adhesive. With another pair of tweezers, she separates the natural lashes to isolate just one. Then the synthetic lash is placed on the natural lash, holding it for a few seconds while the glue bonds. The tech repeats the process, one lash at a time, attaching 40 to 100 lashes per eye. The tech will use several lengths of lashes, attaching the longest artificial lashes to your longest natural lashes. The expected outcome is a dramatic, lush look, so some consumers are surprised when faced with side effects they hadn’t bargained for. Recently, the American Academy of Ophthalmology (AAO) has warned of these dangers associated with eyelash extensions: Irritation and redness. Inflammation and s
