What is LASIK Eye Surgery?

In its most classic sense of the word, LASIK surgery (laser-assisted in situ keratomileusis) employs a specially-calibrated, computer-guided excimer laser to treat nearsightedness, farsightedness, and astigmatism. It is a procedure that permanently remolds the shape of the cornea, the clear covering of the front of the eye, using an excimer laser to help you see more clearly. In nearly all cases, LASIK is pain-free and takes about 8-10 minutes for both eyes.

The LASIK procedure works by reshaping the cornea to enable the light entering the eye to focus properly onto the retina. Numbing eye drops are applied to the eye surface and the surgeon creates a thin circular flap in the cornea. The surgeon then folds back the hinged flap to access the underlying cornea. Using a highly specialized laser with a cool ultraviolet light beam, the surgeon removes and remolds a small amount of tissue to change the shape of the cornea, improving how light rays are focused to enhance your vision. After reshaping the main part of the cornea, the flap is replaced to serve as a type of natural bandage.

LASIK is performed on each eye separately, with each procedure taking only about five minutes. Most patients experience little or no discomfort after LASIK. In as short as 24-hours, patients typically enjoyvision of 20/20 or better without glasses or contacts.

What are the Success Rates of LASIK in San Antonio?

When LASIK and other Advanced Vision Correction procedures are performed by experienced surgeons after detailed in-person consultations with their patients personally, the success rates are astoundingly high. Patients are encouraged to have a detailed consultation with their surgeon prior to the day of surgery, describing all of the potential risks and benefits for their particular situation. We are happy to provide a few general guidelines about what proper expectations should be regarding outcomes for most patients.

In a clinical trial performed by Dr. Parkhurst and presented at the American Academy of Ophthalmology in 2010, 94% of eyes and 100% of patients saw 20/20 or better without glasses after LASIK surgery while 96% of eyes and 100% of patients saw 20/20 or better without glasses after Visian ICL. Dr. Parkhurst has never had to perform a corneal transplant or had a patient experience significant loss of vision after LASIK. We believe this is partly do to careful patient selection. When LASIK surgery is performed on patients who are not suitable candidates, success rates are likely to occur with lower frequency.

NASA followed the Naval Aviation clinical studies of nearsighted patients closely with a particular interest in both safety and quality of vision under extreme conditions. Wavefront-guided and femtosecond lasers provided superior safety with the majority of patients achieving 20/20 or better vision. The Navy studies demonstrated that advanced technology LASIK is stable ad effective in even the most extreme physical conditions or warfare and high-performance flight. With that kind of rigorous testing and validation, the average customer can choose LASIK with confidence.

Is LASIK Surgery Painful?

Typically, no. LASIK surgery is performed with the use of numbing eye drops so that the procedure is typically not felt by the patient. However, in the first few hours after the procedure, it is possible to have a sandy-gritty or typically mild "stinging" sensation while the numbing drops are wearing off and the eye is healing. Any stinging sensation is usually gone by the next morning.

I have a family member/friend who had LASIK. Why do they still need glasses?

The most common reason people need glasses after LASIK is presbyopia. Presbyopia is the naturally occurring loss of near vision that occursfrom the normal aging process in 100% of humans. After age 40, the natural lens of the eye hardens and is no longer able to zoom in close like it could when it was younger.

For people who wear glasses at this age, bifocals are prescribed for far and near vision. For people who wear contacts, were born with good vision, or who had their vision corrected via LASIK, reading glasses become necessary after age 40. This is not a failure of LASIK, but rather an expected event due to the normal aging process. Many of our patients over 40 understand this limitation and still see the value in LASIK, which is to be able to see most things except for the smaller print up close.

There are now several options to treat not onlyfarvision but also near vision after 40. We encourage you to call us at 210-585-2020 or fill out the web form today, to find out how technology has advanced. We may be able to help.

Who is the Best LASIK Surgeon in San Antonio?

The best LASIK surgeons in San Antonio are those that are board certified, are fellowship trained cornea specialists with advanced training in the procedure, have significant experience performing LASIK, know when to recommend against surgery and offer the full range of FDA-approved options to patients seeking vision correction. It is also preferred to have a surgeon who lives and practices in San Antonio full-time in case you have a need for urgent consultation or care with your surgeon.

We admit to being a little biased, and while there are a few well-respected surgeons that we work with, we believe Dr. Parkhurst is one of the top, if not the top LASIK surgeon in San Antonio.  We believe this in part because he was elected by his ophthalmologist colleagues and peers to serve as president of the Refractive Surgery Alliance, an international society of refractive eye surgeons.  Furthermore, he was identified as one of the Top 40 Under 40 Ophthalmologists in the world, by The Ophthalmologist, a publication out of Europe.

Dr. Parkhurst has performed over 15,000 procedures, has written multiple refractive surgery textbook chapters and peer-reviewed journal articles, is the Principal Investigator for multiple FDA clinical trials on new refractive surgery technologies, and he teaches refractive surgery techniques for the American Academy of Ophthalmology, the American Society of Cataract & Refractive Surgery, the International Society of Refractive Surgery, and the European Society of Cataract & Refractive Surgery to name a few.

Dr. Parkhurst has been selected to perform LASIK on many professional athletes, US Olympians, other eye surgeons and optometrists, military fighter pilots, and has performed refractive surgery procedures on his own family members including his mother and father, and has even had the procedure done himself. That broad range of experience and perspective makes Dr. Parkhurst an excellent choice for your LASIK surgery in San Antonio.

What is Z-LASIK?

Z-LASIK uses all-laser technology with a particular femtosecond laser, instead of a microkeratome or mechanical instrument. All laser technology using the femto is more precise and customized to each eye. Dr. Parkhurst is highly experienced in using many femtosecond lasers including Zeimer,Inralase, Zeiss Visumax, LensAR, and LenSx. He is certified to teach other surgeons how to use many of these lasers, teaches his techniques all over the world, and has written several textbook chapters on laser applications in ophthalmic surgery.  Some people refer to LASIK using either Zeimer or Zeiss femtosecond laser brands as "Z"-LASIK.

What is "Custom LASIK"?

Custom LASIK, also known as Wavefront Guided or Wavefront Optimized LASIK is a permanent vision correction solution that corrects nearsightedness, farsightedness, and astigmatism, providing permanent vision correction. It is an advanced form of LASIK that is a procedure performed by some of the country’s thought leading ophthalmologists, including Dr. Parkhurst here at Parkhurst NuVision.

With Custom LASIK, we take detailed diagnosis allowing us to personalize your vision needs treatment. Our advanced vision treatment procedure platform will adjust to your individual vision needs and can be wavefront-guided, wavefront optimized, or a blend of our measurements. By providing custom blade-free Lasik to his patients in the greater San Antonio area, Dr. Parkhurst is able to develop a treatment plan that is unique to each patient, allowing for precisely individualized blade-free Lasik vision correction.

Doctor Parkhurst Perfoming LASIK Surgery

During your free consultation, we will answer any questions regarding your vision or your treatment options.

The custom wavefront exam covers thousands of points across the entire visual system of your eyes with our wavefront diagnostic devices. The detailed exam of your eye is used to guide the laser, enabling Dr. Parkhurst to treat “high order” aberrations in addition to myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. High order aberrations have been found to contribute to roughly 20 percent of a normal eye’s visual defects. For your convenience, Parkhurst-NuVision offers you a personalize Complimentary Lasik Consultation to understand if you are a candidate for these procedures.

Are you a candidate for Advanced Vision Correction? If you are experiencing the following symptoms you may be a good candidate: blurry vision, tired of glasses and contacts, frustrated not able to see across the room, street signs are fuzzy and blurry, low vision at night, have had a stable eye prescription (has not changed) for at least one year, you must be at least 18 years old.

According to the US Food and Drug Administration, the risks of LASIK and PRK can include dry eye syndrome, which can be severe, the possible need for glasses or contact lenses after surgery, visual symptoms including halos, glare, starbursts, and double vision, which can be debilitating, and loss of vision.

After a thorough eye exam, you and the doctor will determine if advanced LASIK is an option for you. Dr. Parkhurst is highly trained in performing Advanced Custom LASIK. Having personally performed over 15,000 ophthalmic surgical procedures, he is one of the most experienced refractive eye surgeons in the state of Texas. He has performed the procedure on professional athletes, military snipers, and fighter pilots as well as his own family members. Because his job as an eye surgeon requires fine-detailed vision, in 2003, he underwent a laser vision correction procedure himself!

LASIK Day – What to Expect

First, it is up to you to understand our easy-to-follow instructions. Our doctors and highly trained staff will describe in detail how to take necessary precautions and use eye drops properly. We will provide a written instruction card for you to refer to with any questions, and because your best vision is our top priority, Dr. Parkhurst provides each patient his direct cell phone number on the day of the procedure in case you need him. Your comfort and care are our number one priority!

While the treatment itself takes only seconds, you should plan to be at our center for over 45 minutes. Dr. Parkhurst uses special anesthetic eye drops (similar to those you’ve experienced during your preoperative exam) to numb your eyes along with a mild sedative that will provide complete comfort during the treatment. Using the femtosecond Intralase laser, Dr. Parkhurst will prepare the cornea for treatment. Dr. Parkhurst then uses an excimer laser to reshape the cornea. The entire process under the laser is usually less than 10 seconds.

After-Procedure Care

Most patients see improved visual recovery within hours! Patients recovering from LASIK are advised to avoid rubbing their eyes, as this could disrupt healing of the cornea. However, most of our patients are able to go to work and continue their daily routine the following day. Contact Parkhurst-NuVision today to schedule your appointment or call (210) 585-2020 to schedule your free, no-obligation consultation.

If you are searching for the reduction or elimination of the need for glasses and contacts, undergoing the Advanced Vision Correction procedure at Parkhurst-NuVision may be the ideal solution.

What are the Risks of LASIK?

LASIK and other Advanced Vision Correction procedures are some of the most successful surgical procedures ever introduced to human medicine. That being said, every surgical procedure performed on the human body (including LASIK) has unfortunately resulted in some complications in rare cases. Following is a list of some of the risks of LASIK:

Under response/Overresponse: During LASIK surgery, the surgeon uses a computer-guided laser to reshape precise amounts of corneal tissue to correct vision. In a biological system, it is possible for some tissues to behave differently than the vast majority of others. If this occurs, it is possible to have a small amount of residual nearsightedness or farsightedness after the first procedure. In most cases, this may be enhanced via a 2nd "fine-tuning" procedure if necessary.  In our experience, enhancement procedures are needed in less than 1% of cases.

Dryness: Some patients have noticed dryness of the eyes after LASIK. In almost all cases, this resolves quickly with the use of artificial tears and healing time in a matter of a few weeks.  It is rare for dryness to be a long-term side-effect or complication of modern LASIK performed on good candidates.  In fact, recent studies show dryness after LASIK is less on average than dry eyes experienced in people who stay in their contact lenses.

Night Vision and other Quality of Vision Disturbance: Some patients have noticed glare and halo's, glare, and starburst at night after LASIK. This is fairly common during the healing period but tends to improve dramatically as the eye heals. This is one area where technological advancement has resulted in significant improvement. Persistent night vision disturbances are now rare, and in more cases improved after LASIK. In a clinical trial performed by Dr. Parkhurst and presented at the American Society of Cataract & Refractive Surgery in 2011, there was a statistically significant improvement in night vision after both LASIK and Visian ICL.

According to the US Food and Drug Administration, the risks of LASIK and PRK can include dry eye syndrome, which can be severe, the possible need for glasses or contact lenses after surgery, visual symptoms including halos, glare, starbursts, and double vision, which can be debilitating, and loss of vision.

In our experience, these risks are extremely rare when patients are selected properly, modern technology is used, and those who may not be good candidates are instructed they may have different or lower risks if they remain in their glasses and contact lenses to see.

Recent peer-reviewed scientific publications on the safety and effectiveness of modern LASIK is proving that our experience is more in-line with results using modern technology across the world. The research is effectively debunking some myths regarding the commonality (or lack there-of) of complications and side effects from older treatment modalities. Recent research performed by current ASCRS President Kerry Solomon, MD titled “Modern Laser in Situ Keratomileusis Outcomes” updated the work from the “LASIK World Literature Review: Quality of Life and Patient Satisfaction” published in 2009. Dr. Solomon analyzed the impact of advanced treatment profiles in LASIK, such as the use of a femtosecond laser and "wavefront ablation" profiles. This analysis evaluated nearly 4,500 clinical study papers on modern LASIK for relevancy and authority. The final data set included 97 high-quality studies that together represented over 67,000 procedures. In this very large analysis, 99.5 of patients achieved at least 20/40 vision, with 90.8% achieving 20/20 vision. From a safety perspective, fewer than 1% of patients lost two or more lines of vision on the eye chart in this very large aggregate analysis.

In another prospective, multi-center study published in August 2016 in Ophthalmology (one of the most respected peer-reviewed scientific ophthalmic journals for physicians) by Price et al., the researchers looked at approximately 1,800 patients over a three-year period, 694 who stayed in contacts versus 819 contact lenses users who graduated to LASIK.  They compared patient-reported levels of satisfaction with vision, risks, and benefits between contact lenses and LASIK. This study formally compared these two common methods of refractive correction, which hadn’t been done on this scale in the past. Patients in the contact lens group reported having more abrasions, infections, complaints of dry eye, and worsening night vision/glare compared to those patients who went on to have LASIK. Furthermore, people who had LASIK surgery, compared to those who stayed in their contacts, were more satisfied with their vision on every metric and at one, two and three years out.

Yet another recent study of 574 people (262 active duty military personnel, 312 civilians from five investigational sites) performed at the behest of the FDA specifically looked at patient satisfaction after LASIK. This large, FDA-monitored study, referred to as the Patient-Reported Outcomes with LASIK (PROWL) protocol, showed that satisfaction after LASIK is extremely high. Early PROWL results showed overall patient satisfaction rates of more than 96%. Also, visual symptoms, such as glare, starbursts, ghosting, and halos, decreased on average. More than twice the number of patients reported their pre-operative visual symptoms were gone at three months than those who reported an increase in symptoms at three months out.

As a successful laser vision correction patient himself back in 2003, Dr. Parkhurst and his colleagues recently published a paper showing that over 90% of refractive surgeons have recommended or performed refractive surgery on their immediate family members, and that refractive surgeons are approximately five times more likely to have already undergone refractive surgery on their own eyes than the general public.  Dr. Parkhurst is one of the many vision correction surgeons who has not only had laser vision correction on his own eyes but also recommended and performed LASIK and other advanced vision correction procedures on his immediate family members, including his own mother and father.
