Pregnancy, Breastfeeding, and LASIK


Pregnancy, Breastfeeding, and LASIK


Many potential LASIK candidates inquire about the relationships between pregnancy, breastfeeding, and LASIK.  In the most basic terms, LASIK is not an option for women who are pregnant, planning on becoming pregnant, or lactating.

One of the main reasons why LASIK is not suitable for pregnant or breastfeeding women is the fact that both pregnancy and lactation can cause eyesight changes.  The hormonal fluctuations that women go through in these conditions cause the body to retain fluid, even in the eyes.   When the eyes’ lenses swell, the way they bend or refract light changes, which causes vision to be slightly distorted. 
In order to make eyesight clearer, LASIK changes the way the cornea refracts light.  Prior to conducting a LASIK procedure, our certified LASIK surgeon carefully diagnoses each eye’s refractive error using Wavefront technology, which produces a 3-D map of the irregularities in each of the corneas.  The LASIK procedure utilizes this information to determine the correction that needs to be done.  If a diagnosis is made while the patient is experiencing fluctuations in their eyes as a result of pregnancy or lactation, their refractive error could be overcorrected or under corrected, resulting in unsatisfactory vision results.
Aside from the potential result of unsatisfactory results due to pregnancy or lactation, the medications associated with the LASIC procedure could be harmful.  The antibiotic eye drops and inflammation reducing cortisone eye drops that are part of the necessary post-operative care for LASIK patients could harm a pregnant mother and her child if absorbed into the bloodstream, especially during the first trimester.  Further, eye drops used to dilate the pupils have not been tested on pregnant women, and studies have not been done to discern whether or not any of these medications, if absorbed into the milk supply of a lactating mother, could harm the baby. 
Lastly, dryness in the eyes, the predominant symptom of the LASIK procedure could cause problems for pregnant women as it is a symptom of both LASIK and pregnancy.  Typically, the dryness resulting from LASIK is temporary, but in some cases, it can develop into Dry Eye Syndrome, which must be managed long-term.  The combination of pregnancy and LASIK could cause particularly dry eyes post-surgery.
Because of these health factors and risks, if you are hoping to have the LASIK procedure but are also planning on becoming pregnant, you must have the baby, finish breastfeeding, and allow at least three months before going through with the operation.

The Better Technology of the Wavefront


The Better Technology of the Wavefront

Today, many LASIK surgeons use outdated LASIK equipment for their procedures under the false assumption that they can create satisfactory results with old technology.  Such suppositions, however, are vastly inaccurate due to the advancement in technology used in Wavefront guided laser treatments, the same treatments we use here at InSight LASIK and Refractive Group.
Wavefront laser vision correction provides vision clarity for people with nearsightedness, farsightedness, and astigmatism that the older equipment of traditional LASIK simply cannot achieve.
Most eyes experience blur, glare, or halo effects around lights, even with the best glasses and contact lenses.  In the past, post-LASIK patients experienced exaggerated effects of these visual distortions.  Such problems are caused by small irregularities, medically referred to as higher order aberrations, in the way that light is refracted, or bent, by the optical system.    However, with the updated technology of the Wavefront guided laser treatment, such distortions can be significantly reduced or even eliminated completely. 
The Wavefront makes these results possible by measuring all of the lower and higher aberrations of the eye which allows us to create a laser treatment plan that is unique to every individual.  The Wavefront technology makes LASIK the ultimate in customized designer surgery, and as a result, many patients achieve vision even superior to normal 20/20 acuity. 
With the wavefront guided treatments that we offer at InSight LASIK and Refractive Group, we can help you to achieve exceptionally clear vision without nighttime glare and halos, so that you can have the best sight possible.

Understanding Common Focusing Errors


Understanding Common Focusing Errors


Focusing errors fall under four categories: Myopia, Astigmatism, Hyperopia, and Presbyopia.  Below is a guide to understanding the characteristics of each of these optical conditions.
Myopia:
Myopia is the medical term for nearsightedness, a condition that affects more than 70 million people in North America.  It occurs when the eye is too long for the curvature of the cornea.  As a result, light rays that enter the eye do not come into sharp focus on the retina which is at the back of the eye, and instead they focus further forward.  The result of this skewed focus is blurred vision.
The term ‘nearsighted’ means that one can see ‘near’ objects clearly without glasses or contact lenses, but objects that are further away are blurry.  The condition occurs in varying degrees.  The more myopic  a person is, the blurrier the appearance of distant objects, the higher the eyeglass prescription, and the thicker the lenses.
Of all myopic people, about 90% have corrections that are less than -6.00 diopters.   Below shows the categories of myopia severity:
Mild Myopia                                       < -3.00 diopters
Moderate Myopia                                    -3.00 to -6.00 diopters
Severe Myopia                                        -6.00 to -9.00 diopters
Extreme Myopia                                  > -9.00 diopters
Astigmatism:

Many myopic patients have a degree of astigmatism.  In fact, it is the most common refractive condition.  Astigmatism occurs when the eye is oval shaped instead of being a perfect sphere.   As a result, patients with astigmatism experience distorted or tilted images as a result of the unequal bending of the light that enters the eye.  Patients that have high degrees of astigmatism have blurred vision for both near and far objects.

Below is a list of the categories of severity of astigmatism:

                                                      Mild Astigmatism                           < 1.00 diopters
                                                      Moderate Astigmatism                       1.00 to 2.00 diopters
                                                      Severe Astigmatism                           2.00 to 3.00 diopters
                                                      Extreme Astigmatism                      > 3.00 diopters
Hyperopia:

Hyperopia is the medical term for ‘farsightedness’ and it occurs when the eye is too short for the corneal curvature.  Light rays focus behind the retina, which produces a blurred image.  Farsighted individuals can use their focusing muscles to move the image forward into the retina, but distant objects are seen more clearly than near objects.  Laser technologies, like LASIK, can correct this condition.

Presbyopia:

Presbyopia is part of the normal aging process, where the lens of the eye loses some of its flexibility.  The condition usually occurs between the ages of 40 and 50, and everyone experiences some degree of presbyopia.  As a result, many nearsighted people begin wearing bifocals in the forties, and people who have never worn glasses may begin to need reading glasses.

An advantage of mild myopia is the ability to stop wearing glasses after age 40 as the myopia counteracts the presbyopia.  The downfall of LASIK is that it causes patients to lose this ability.  As LASIK produces normal sight in individuals, LASIK patients begin to need reading glasses like any other normally sighted person would, when they reach the age of 40 or 50.

Understanding Optical Prescriptions


Understanding Optical Prescriptions

Most people know the numbers that signify the prescription of their eyes, but not everyone understands what they mean.  To better understand your own eyes, here is a brief guide to reading optical prescriptions:
Visual refractive disorders such as myopia, astigmatism, hyperopia, and presbyopia are measured in units that are known as diopters.  Diopters represent the amount of correction that is needed to achieve normal vision.  The more nearsighted or farsighted a person is, the higher their prescription is in terms of dippers.
Prescriptions are written in three numbers.
As an example, -5.00 -1.50 x 180 represents a typical prescription.
The first digit signifies the degree of nearsightedness or farsightedness.  The sign identifies whether the person is nearsighted (which is demonstrated by a - sign) or farsighted (which is demonstrated by a + sign).  In the case of the example prescription above, the first number (-5.00) shows that the person is nearsighted to a degree of 5.00 diopters.
The second number identifies the degree of astigmatism.  It can be written with either a + sign or a – sign.  The example prescription shows that the patient has astigmatism of 1.50 diopters.
The third number is the axis, which indicates the direction of the astigmatism.  In the example, an axis of 180 degrees means that the astigmatism is in the horizontal direction.
In terms of connecting these numbers to LASIK eligibility, most excimer laser studies have found that the average laser patient has a prescription between -3.00 and -4.00 diopters of myopia with less than 1.00 diopters of astigmatism.

DJ Scottro's Personal Experience with LASIK

96.1 Kiss FM's late night DJ with Dr. Zimmer

DJ Scottro's Testimonial after his LASIK surgery at InSight LASIK Group in Cranberry Township

If you are interested in viewing his video of his experience please click here!

"For all of my adult life (and a lot of my adolescent years) I haven't been able to see without glasses or contacts. Poor vision hindered my athletic endeavors and social interactions for a long time… but not anymore.

When I found out I would be receiving the LASIK procedure from Dr. Dan Zimmer at InSight, I was pumped! And kind of nervous.  I NEED my eyes… you know, to see and stuff. But as soon as I walked through the door at InSight LASIK & Refractive Group, Lynn and the staff took me in like family and laid it all out for me. They walked me through the entire process step by step from top to bottom, answering all of my inquiries along the way.  
I've heard some horror stories about other patients that went to sub-standard facilities and had doctors that were just trying to make a buck.  Not at InSight. They actually care about helping people achieve better vision.

I was amazed that I didn't feel a thing. It was almost surreal. It took about 15 minutes total and as soon as I sat up, I could see the clock on the wall. Something I hadn't been able to do since I was a little kid. And off I went. After a nice long nap I woke up, and could see for miles. Literally perfect vision within hours of the procedure!

Bottom line, my experience at InSight LASIK Group has changed my life.  Truly great people who are amazing at what they do and also care about their profession. They left me smiling from ear to ear and able to see perfectly. Dr. Dan, Lynn, and the entire staff are truly the best at what they do, and anyone considering this procedure would be insane not to go to InSight!"
