LASIK

 
Individuals consider the option of refractive surgery and EPILASIK for a variety of very personal reasons.While EPILASIK does not promise perfect vision, it does hold the promise of reducing one's dependence on contact lenses or glasses, which will allow many people to more freely pursue their hobbies, sports activities or career options.
Sports Enthusiasts - from weekend warriors coming on bikes from Camarillo,Fillmore,OjaiOxnard,Port Hueneme ,Santa Paula,Simi Valley,Thousand Oaks,Ventura, to professional athletes from Moorpark , many wish to be reduce their need for contacts or glasses for safety or performance reasons.
Mothers of Young Children - many women express concern about the safety of their children if they should lose their glasses or contact lenses -- while playing in the surf or trying to escape a burning building, for example. EPILASIK may even reduce the anxiety produced by simple tasks, like finding one's way through the house at night.
Frequent Travelers - for those who spend a considerable amount of time on the road, being less dependent on glasses or contacts promises numerous advantages, from safety (ability to read evacuation signs) to convenience (less to pack).
We remind all patients that EPILASIK is a surgical procedure, and like all such procedures, there are risks involved. We also suggest that you review information you find elsewhere through additional research and then discuss this information in depth with your ophthalmologist.

Hail the King.
From plantation slavery to The Cabinet.
This journey requires courage determination and a futuristic vision.

A DAREDEVIL 29,000ft hike to the summit of Mount Everest by a group of climbers who had all undergone Lasik surgery indicates that the procedure is safe for those pursuing adventure in the most extreme conditions.

Six climbers who underwent Lasik embark on 29,000ft hike to the summit of Mt Everest to examine the effects of hypobaric hypoxia on the cornea.
The extraordinary climb was organised by ophthalmologists Geoff Tabin MD and Jason Dimming MD, who are also mountaineers. It is one of the few studies to look at the effects of hypobaric hypoxia on the cornea following Lasik and the only one examining the phenomenon at such altitude.
Climbers preparing to scale Everest must undergo a lengthy period of acclimatisation at altitude, which includes spending at least one month at base camp altitude of 17,600ft, as well as repeated visits to higher camps at 20,000ft and above.

After acclimatisation, an attempt at the summit typically involves one night each at 20,000ft, 21,300ft, 24,000ft and 26,400ft, before the final push to 29,028ft.
The mountaineering ophthalmologists monitored the visual acuity of 12 eyes of six climbers in the expedition. They obtained refractions at sea level before and after the climb and at the 17,600ft base camp before and after the climbers attempted the summit.
They measured intraocular pressures at base camp using a portable tonometer and tracked the climbers’ subjective visual experiences at higher altitudes.

“Such extended time at and above 17,600ft provided an excellent model to study the effects of hypobaric hypoxia on the cornea after Lasik,” noted Dr Tabin, who in 1988 became the first ophthalmologist to reach the top of Everest.
All the climbers in the expedition reached 26,000ft, with four who had bilateral Lasik reaching the summit. All used supplemental oxygen above 26,400ft.
Five of the six climbers reported no subjective visual changes at up 26,400ft. One team member reported some blurring of vision above 16,000ft and two climbers reported similar problems above 27,000ft.

Three of the four who reached the summit reported no visual changes at the peak. One climber who reached the top reported some transient blurring. In each case the blurring improved with the subsequent descent and the use of lubricating drops.
One climber who reached the summit reported a milky haze above 28,500ft but this disappeared on descent. He noted that the haziness was not accompanied by any myopic shift, an effect reported by a climber who climbed Aconcagua in Argentina after undergoing Lasik.

Another climber turned around at 27,500ft when he developed a similar problem. He described his blurred vision as “like looking through waxed paper”. His vision returned to normal with 36 hours after descending to a lower altitude. All of the eyes returned to pre-climb visual acuity when the climbers returned to base camp.
One adventurer, who had attempted Everest previously while wearing glasses, experienced decreased visual acuity (to 20/30) at the summit. He noted: “All in all, the advantage of not having glasses on Everest far outweighed any loss of visual acuity I had on the mountain.”

“Having Lasik was the best training for Everest I’ve ever done. The view from the top was the best I’ve ever had,” said another climber, Peter Athans MD, who reached the summit without difficulty. He had previously climbed to the summit of Everest six times, the most ascents by any non Sherpa climber, while wearing contact lenses.
Dr Tabin suspects that the problems encountered by climbers who experienced difficulties were surface-related. Those who climbed to 27,000ft and above in particular may have experienced corneal oedema or corneal surface changes associated with dry eye induced by oxygen flow from the facemask. Even at the lower altitudes, he believes dry eye may have been associated with the visual changes.

“Dry eye may be biggest concern with Lasik in extreme conditions. Climbing at altitude is very dry and there can be a lot of wind. Any climber who has undergone Lasik needs to be evaluated for dry eye and to be maximally treated prior to going. They should also be advised to bring appropriate drops on the expedition,” Dr Tabin told EuroTimes.
The amount of time elapsed after surgery did not appear to predict complications. The climbers had undergone Lasik anywhere from six weeks to three years prior to the expedition.

One of the climbers who had minor problems at the highest altitudes had undergone Lasik only three months prior to the hike, while the other underwent surgery three years previously. Similarly, two climbers who reached the summit without encountering any problems underwent surgeries at six weeks and three months earlier respectively.

The above article is an excerpt from the Eurotimes.

An optometry resident asked how to convert mm to dioptres when dealing with contact lenses.

Formula: 337.5/mm = Dioptres

That is, 337.5 divided by EITHER you dioptric measurement, OR your millimetres of radius, will instantly convert to the other corresponding mesurement.

Dr. Khanna does a great job of explaining exactly what Lasik surgery is, and what we as patients can expect as an outcome.

What a gift it is to see clearly each and every moment of my life! No more glasses. No more itchy contacts. No more blindness in the pool and ocean. Clarity every waking moment. I started wearing glasses/contacts at age 28 when I realized I couldn't make out numbers on uniforms at baseball games and basketball games. Sports writers can't write about what they don't see! I wore glasses and contacts for 12 years and never was really comfortable with either as I also suffer from chronic dry eyes. After careful consideration of several doctors in the Ventura County area, I chose Dr. Khanna for my Lasik surgery. I was immediately warmed by the staff in Dr. Khanna's office and knew I would be in good, capable, caring hands. I was always treated with respect and importance. I can't say the same for the other three offices I visited in the Ventura area. My first impression of Dr.Khanna and his staff was on the money. I always felt safe and I went from 20/70 vision to 20/10 in a matter of minutes. That is not a typo, 20/10! The surgery was quick, mostly painless and enjoyable (Dr. Khanna, Brandis and Michelle have a pretty good comedy routine during surgery if you ask for it). Here I sit, three months later, still testing 20/10 and never missing a visual opportunity. Now for the big cliche: I should have done it sooner! What was I waiting for?

Frequently Asked Questions
About Dry Eye Disease


1. What is dry eye disease?

Dry eye disease is a common condition that affects millions of Americans – women more often than men. In some instances, it is characterized by dry, irritated eyes due to a lack of lubricating tears. Surprisingly, it can also be a result of excessively watery eyes due to tears lacking the proper balance of mucous, water, and oil to coat the eyes properly. Chronic dry eye can lead to damage of the eye’s surface, an increased risk of eye infections, and eventually, the inability to produce tears. Left untreated, severe forms of dry eye can even damage your vision.


2. How do I know if I have dry eye disease?

Symptoms of dry eyes may include burning and stinging. A foreign body sensation, like sand being in the eye, is often encountered. Vision can be blurred. Reflex tearing may be triggered causing excessively watery eyes. Sometimes, redness of the eye is experienced. When looking in a mirror, the eyes may seem to have lost their normal clearness and luster.


3. What causes dry eye disease?

C Environment

Sunny, dry, or windy weather, heaters, air conditioners, and arid high altitudes increase the evaporation of tears from the surface of your eyes. You may experience dry eye symptoms while viewing television, computer screens, or while reading. These environmental stress factors can make dry eye disease worse.

C Tear Drainage

If you have too much tear drainage, you may experience dry eye symptoms and related congestion of the nose, throat, and sinuses.

C Contact Lens Wear

Contact lens wear increases tear evaporation and related dry eye symptoms. Dryness may result in protein deposits on the lens, eye irritation, pain, infection, or sensitivity to contact lens solutions. Dry eye symptoms are the number one reason people stop wearing contact lenses.
C Aging

Tear production gradually decreases with age. At age 65, the tear glands produce significantly less of the lubricating tears than produced at age 18. Decreased tear production may cause eye irritation and excess tearing or watery eyes.

C Medications

Tear production may be reduced if you take certain medications, including decongestants, antihistamines, oral contraceptives, tranquilizers, and diuretics. If you are taking any medication, as your doctor if it contributes to your dry eye condition.

C Health Problems

Some special health problems can result in side effects of dry eye disease, such as arthritis, diabetes, thyroid abnormality, asthma, or an autoimmune condition known as Sjörgren’s Disease, which affects mostly middle-aged women. Also, women experiencing hormonal changes, such as pregnancy or menopause, may contract dry eye.


4. Can dry eye disease affect my ability to wear contact lenses?

Yes. Dry eye disease is the leading cause of contact lens intolerance or discomfort. Contacts can cause tears to evaporate from the eyes causing irritation, protein deposits, infection, and pain.


5. How is dry eye disease treated?

Common treatment of dry eye disease includes the use of artificial tears or artificial tear ointments; however, excessive or prolonged use of artificial tears can disrupt the eyes natural production of tears leading to further aggravation of the condition instead of providing desired relief.

Other treatments for dry eye disease include the following:

C Wearing special eyewear, such as goggles or moisture chambers.
C Temporary plugs in the tear drain (punctum) to allow the eyes time to gain full use of the lubricating tears before they are drained away from the eye.
C Laser treatment or minor surgery to close the punctum permanently.

Now there is a new breakthrough approach to treating chronic dry eye. We suggest you schedule an appointment to talk to one of our doctors about this new drug therapy.
