12 Steps to Deal with Dry Eye After Lasik
Posted by Dr. John Suson in Milwaukee Eye Care on June 25th, 2009
Dry eye is something that can occur after Lasik eye surgery and every patient should be aware of it. Actually, studies indicate that tear production and blink reflexes are reduced in all patients that undergo Lasik, but it does not usually cause any symptoms. The cause of the dry eye is due to the disruption of the corneal nerves by the cutting of the Lasik flap and the excimer laser treatment of the cornea itself. The deeper the treatment goes, the more likely that dry eye symptoms will occur. Actually, recent studies have shown that contact lens wear also causes increase in dry eye over time. This contact lens effect is a slower, more chronic process. Because it happens so gradually, contact lens related dry eye takes longer to be noticed by a patient whereas a Lasik patient may be aware of it within days or weeks.
For those rare patients that experience dry eye symptoms, as the cornea heals over a three to six month period, the nerves regenerate and much of the dry eye problems will resolve. Nonetheless, there are a number of measures that can be taken to speed the process and make it a better overall experience for the patient. The sooner the dry eye resolves, the sooner you will be more comfortable and your vision will return to its crispest potential. I have even seen some second opinion patients that were 6 months to a year after Lasik that never had their dry eye problems aggressively treated and still had persistent discomfort and moderately diminished (although annoying) vision. It seems to me that many chain surgery centers and surgeons under treat dry eye because they perceive it as a minimal problem whereas the some patients may feel it is significant.
I use a number of strategies to minimize and treat dry eye in all of my Lasik patients:
Wavefront Guided Lasik and Night Driving Performance

Wavefront Guided Lasik and Night Driving.
Wavefront Guided Lasik treatments use a highly advanced method of scanning the eye for higher order optical aberrations. It has been known for some time that using the excimer laser to eliminate these optical aberrations gives better visual outcomes in situations of low light compared to conventional Lasik treatments. The Wavefront system that I use is called the Visx Star S4 IR Customvue™ system.
Epithelial Ingrowth After Lasik Surgery
Posted by Dr. John Suson in Milwaukee Eye Care on May 29th, 2009
One well known complication of Lasik Surgery is Epithelial Ingrowth. Epithelium is the very fast growing cell layer that covers the eye. Actually, there is an epithelium that covers every part of the outside of your body. It is rapidly growing and constantly shedding and renewing itself throughout your lifetime. The epithelium should remain on the very outer surface of the body, but at times we can see it grow beneath the surface where it becomes trapped and cannot properly shed and renew itself. On the skin, epithelial ingrowth appears as a cyst or bump and has only a cosmetic consequence.

Lasik for Military Pilots and Astronauts
Posted by Dr. John Suson in Milwaukee Eye Care on May 19th, 2009
In my last blog, I wrote about the reasons that I chose to have Lasik eye surgery to improve my vision and function at work. Of course, as a surgeon, my vision is critical to what I do and there are many other professions where that is the case too. One of the most important professions where vision is vital is the military. Not surprisingly, a lot of the most respected and rigorous research work into Lasik and PRK has been by armed forces ophthalmologists who try to determine the appropriateness of different kinds of refractive surgery for military personnel.
Why does an Eye Surgeon get iLasik?
Posted by Dr. John Suson in Milwaukee Eye Care on May 15th, 2009
People have refractive eye surgery (usually Lasik these days) for many reasons including lifestyle, functional, or cosmetic issues. I had Lasik and my reasons were largely due to function. Previously, I wore contact lenses, but as time passed and I grew older, my eyes became less and less tolerant of them. I remember very well the moment that I realized that contact lenses were becoming a problem for me. I was an eye surgery resident in the middle of a surgery. My eyes were bothering me from dryness and allergy, so my contact lenses were quite irritating. This problem had been increasing steadily over time so that usually by early afternoon I could no longer wear the contact lenses. In this case, while I was doing surgery, the problem became so bad that one contact lense actually popped out of an eye. Luckily, it was toward the end of the surgery and I was able to complete the case without incident using just one eye. From that time until I had Lasik, I did all my surgeries wearing glasses.
