Hi. Welcome. This is doctor Khanna. I want to talk to you about fear of eye surgery. This lesson is divided into three parts. Today’s lesson is on why we are so afraid of eye surgery. In the forth coming lesson, we will discuss how to overcome the fear. Why are we so afraid of eye surgery, we have to delve back into evolution, our upbringing and find some answers there. People are always afraid of the dark. Remember when you were a kid; you thought that there might be a monster in the closet or under the bed. People are afraid to go to the graveyard but today it is so much better. There are streetlights everywhere and we have a phone with flashlight on it.
Imagine Sherlock Holmes going out in the night when there is fog and mist around. There is an inherent fear in us coming from the times we lived in the forest. In the night, predators would come out and that fear has continued. Another thing you might have heard of is insomnia, when people are unable to sleep. It is very interesting why some people find it difficult to fall asleep and the simple answer might surprise you. The answer could be that they are afraid that they may not be able to get up if they go to sleep. They are afraid to lose their consciousness and go into a semi-conscious state. It is inculcated in every culture. Each civilization that is present on earth celebrate the festival of light in the dark days. That is their hope to overcome the darkness.
Another fear the people have is for the white coat. It is funny that people can check their blood pressure at home and it is okay and then they come to the hospital and see the white coat and the blood pressure shoots up. These are all evolutionary mechanisms that are built in for safety to preserve us and they all stack against us. There is one more called the menace reflex; when something comes near the eyes or when we sneeze, they instantly close. That is encoded in our DNA.
Corneas and eyes are every important. In fact, some evolutionary biologists feel that this reflex may have pre-dated the existence of eyes. Small microorganism who do not have eyes have had light shun on them and they immediately move away. All those things combined in the subconscious and conscious mind are all playing to develop fear about eye surgery. Do not feel fearful.
In the next lesson, we are going to come up with methods that are time tested and true to see, how we can overcome the fears regarding eye surgery. Thank you
Newer LASIK is here. The laser used for lasik is shinier faster and more accurate. These factors make it more safer. We always focus on safety. The more safer the procedure the less fear we will have- consciously and subconsciously.
Do you think all LASIK are the same?
Just like all cars are not the same, even though each one usually takes us to our destination. LASIK quality may vary depending on the surgeons experience, LASER used.
It has become much safer since the early days of LASIK in the nineties.
The tracker can follow all micro movements of the eyes.
Experienced surgeons know the limitations of LASIK
Current 4th generation LASERS are more precise. Utilizing knowledge of maths and physics the shape of cornea is maintained similar to that before surgery. This reduces aberrations, which was another cause for visual dissatisfaction. Early lasers were whole beam lasers like carpet-bombing, Newer ones are flying spot or variable spot, yielding precise placement only where needed
The diagnostic Wavefront devices can map visual errors more accurately and even show the surgeon what the patient is seeing.
The flap designing instruments are more refined and tested. They are more friendly to the eyes.
Sterilization techniques have improved.
Blend zones (a way of applying the computer controlled laser) and larger zones have decreased the incidence of glare and haloes.
More than 5 million procedures have been performed. The cumulative data has yielded learning points which would have taken a surgeon a lifetime to accumulate. Dedicated LASIK surgeons have access to this data, and can use the wisdom of their peers. As the computer chips have advanced they have increased the speed and response rate of the lasers. The surgeon has power to override all these gizmos. Hence an attentive surgeon with quick reflexes is still the most important.
If not candidate for LASIK, Advanced surface ablation or epilasik an option.
Blended vision for better distance and near reading.
Newly discovered drops reduce pain and increase tear production. Modern materials help preserves tears and keep the eyes moist
As important as the car is the driver. Age restrictions. Numbers of successful surgeries done are important.
Are lasers maintained by authorized companies? The assistants are certified and only Licensed operators used.
If by any chance you were not able to comprehend the stuff above it does not matter- rest assured we understand. We apply the same knowledge when we touch your precious eyes – so place your trust in us.
If you use corrective lenses or contacts, chances are you’ve heard about Lasik Eye Surgery as a permanent vision correction option for certain candidates. With continued research and technology, ophthalmologists have developed a less invasive procedure called Super Lasik eye surgery. Instead of cutting a flap into part of the deeper, permanent corneal layer, Super Lasik is a “No-Cut” surgery that only opens a flap on the outermost layer of corneal cells, therefore making it a safer option.
Super Lasik can correct most vision conditions caused by a misshapen cornea. Patients with near-sightedness, farsightedness, or an astigmatism are eligible to have their conditions corrected with this quick laser surgery. Even if you’ve been turned down as a candidate for traditional Lasik, you can still be considered for Super Lasik, since it’s less invasive. An ideal candidate for this procedure is over 18 years old, has a stable prescription that doesn’t change more than 1.0 in a year, and has a prescription between -14.0 and +6.0. However, the ultimate decision for candidacy can only be determined in a consultation with an ophthalmologist.
The actual procedure is very simple and quick, taking between four to six minutes per eye. After numbing the eye with eye drops and marking the cornea with a ring of dye as a reference point, the eye is held open by a retainer and the surgery is ready to begin. Using an epikeratome, a vacuum-like instrument that helps to cut specific points of the cornea, the surgeon gently opens a flap of the outer layer of the cornea and applies a cool beam of light that gently reshapes the cornea, correcting the eye vision conditions specific to each patient. Then the surgeon places back the corneal flap in its original position and the cornea begins to heal immediately. Right after the procedure is finished, the patient takes home a few bottles of medicative eye drops to use for the next few weeks that aid in the healing of the cornea and most patients regain their vision within a day or two. This entire process is painless and has minimal patient discomfort.
Super Lasik is a great option for patients ineligible for traditional Lasik or prefer a less invasive, safer procedure and can create permanent 20/20 vision without the discomfort or price of correction lenses and contacts.
