Patient Profiles 

One of the best ways to learn about vision correction is to talk to, read about, and learn from people who have already had similar care. We invite you to browse here a very broad selection of profiles about our patients.

Our profiles include data on:

  1. Unaided vision before and after treatment;

  2. Prescription before and after treatment;

  3. Age, occupation, and photo (if provided);

  4. Certain special case concerns;

  5. Comments from patients; and

  6. Comments from Dr. Wallace.

We invite you to browse by the various treatment types listed in the 'right rail' (column at right).  Or, to review all patient profiles, simply select one of the featured patients, then the "Next" or "Previous" tabs on the individual profile pages.

These are real people, and their letters speak for themselves. To respect and protect the privacy of these patients, we have identified them only by first name in the letters published here.

RE: Question for Dr. Wallace... High Altitude and LASIK

Question...
You performed a successful and amazing surgery on my eyes a couple of years ago. I have had no problems with my new eyesight and am greatly appreciative of the procedure. However, since having my corrective surgery, I have ventured into the exciting domain of mountaineering (I have since moved from LA to Colorado). I have hopes of summiting high altitude peaks in the near future. To date, I have only climbed to 14,000 feet (with no eyesight problems), but have a trip planned to 18,000' (Mexican Volcanoes) in November, then another trip to 22,500' (Aconcogua) in February. I have been trying to research the effects of altitude on corrected vision with Lasik, but have not found any information (research indicates problems with RK surgery). Do you have any current information on studies of this nature? I'm REALLY hoping that my awesome surgery won't cause any problems at high altitudes... please advise.

Thank you, and again... thank you Dr. Wallace for my perfect vision (well... at least here, at 9,500 feet!!!)

Doctor Wallace says:

Hi, Kelly,

Glad to hear everything is going well for you in Colorado. You are correct; radial keratotomy (""RK"") can and did cause problems for one of the Everest climbers, Beck Weathers, that contributed to his demise in the terrible '96 season chronicled by John Krakauer's ""Into Thin Air"". Weathers' visual problems, along with other major errors in judgment, and brutally severe weather, led to numerous casualties that year on the mountain. Since then, intelligent climbers and trekkers have been wise to inquire about their own risk factors, and ask whether LASIK is different than RK in regard to altitude-related risk.

What was not well reported at the time was that Weathers had undertaken RK surgery something like ONE WEEK before flying to Kathmandu and then Everest base camp. Apparently, he did not inform his eye surgeon about the imminent plans to climb Everest, nor did he advise his mountain guides that he had just received RK surgery. The short interval from surgery to altitude challenge certainly made things far worse than they might have been for him otherwise.

Thankfully, RK surgery is now obsolete, having been replaced by the much more accurate and stable methods of laser vision correction (LASIK nd PRK). The radial, deep corneal incisions of RK have been eliminated in favor of very superficial laser sculpting as in the latter procedures.

You may also find solace in knowing that the partial pressure of oxygen at 29,000 feet is much lower than the partial pressure on either Anconagua (I think peaking at 22,500) or in the Mexican volcanoes which you say are in the 18,000+ range.

The other good news is that LASIK does not pose the same altitude hazard as RK, even shortly after surgery. A friend of mine did a LASIK fellowship in Argentina in '97, and his wife had LASIK there just before he finished. Two weeks later they went trekking in the Cordilliera Blanca, I think, climbing to above 16,000 ft. He brought along some testing equipment, measured her vision and a bunch of other parameters, and actually wrote this up in one of the ophthalmology journals. She did fine; had no problems, not even any temporary blurring; she retained great vision, and they are still (happily!) married.

Have a great time, stay healthy, hike well and send us a postcard when you can! And keep enjoying that great vision.

Dr. Wallace

NOTE: Kelly had LASIK in August, '00. Her referring optometrist informed me of that her vision after surgery was 20/15 in one eye and 20/20 in the other. She was, to say the least, extremely pleased with her vision, and that was before the correspondence noted above. - DW
