Dr Khalil answers frequently asked questions about LASIK

Dr Ahmad Khalil answers questions about lasik and vision correction in Cairo, Egypt at his Dokki Eye CLInic
Is the effect of LASIK permanent?
Yes! When properly done for the suitable person. Following an initial healing period of two to three months, the effect of surgery is lifelong.
Who is a candidate for LASIK?
LASIK candidates are generally active people who are unhappy with their current system of vision correction: glasses and/or contact lenses. Candidates must have healthy eyes, and be at least 18 years old. There is no upper age limit! Also, your vision must be stable for at least one year before the procedure. For example, you need to have worn the same prescription for that whole year.
Is LASIK safe?
NASA approved the use of advanced Lasik surgery for U.S. astronauts. LASIK is also already approved by the Navy and more recently the Air Force for use on fighter pilots. Naval aviator clinical trial data however, made a compelling case that the procedure could withstand even the most extreme rigors of warfare and flight. The American Food and Drug Administration (FDA) recognizes LASIK as proven, safe and effective. According to guidelines recently released by the Eye Surgery Education Council (ESEC), fewer than 1% of patients who have received LASIK to date have experienced serious, vision-threatening problems. Most LASIK complications can b e treated and usually resolve within several months of surgery. There are no known cases of blindness resulting from LASIK
What is the right age for laser vision correction?
the minimum age for regular laser treatment is when the power of the eye (glasses prescription) stabilizes, and that usually is between 18 and 21 years. Dr Khalil recommendation is to wait till the age of 20 with most cases. There is no maximum age, provided that there is no other abnormality in the eye. Dr Khalil has treated patients between 18 and 66 years
I don't live in Cairo, for how long do I have to be in Cairo for the LASIK operation?
A minimum of 3 days is required to hav the full consultation with Dr Khalil in one day, the operation, if decided on the following day, and an important first follow up visit a day later. You will be encouraged to come for another follow up visit within a week or so if available, and you will always be welcome to drop later for an eyes check
What are the success rates with laser vision correction?
Overall, 80% of patients will have perfect (6/6) vision without glasses, and 98% of the patients will see well enough without glasses to pass the driver's license eye test (6/12). The results are better than this for patients with low amounts of nearsightedness. Unsatisfactory results often can be improved by retreatment when indicated.
What are the most common negative side effects of laser vision correction?
Although no one knows the exact number of complications, studies suggest that the incidence of minor difficulties such as dry eyes and nighttime glare is around 3% to 5% from combined LASIK and PRK procedures.
These minor complications include:
Halos - Some patients will notice glare halos or starburst around objects in low-light conditions. For the vast majority, these symptoms are temporary. However, others will continue to experience them for several months or longer. During pre-operative evaluation, the refractive surgeon can determine whether or not a person is at high risk for seeing long-term halos.
Dry eyes - There is increased dryness of the eyes typically for several months following LASIK, though some patients may experience dryness for a longer period of time. It is important to use lubricating drops frequently. If the eyes remain dry for prolonged period, there are other drops or techniques that can help. Pre-operative evaluation will help determine whether or not a person is a likely candidate for experiencing dry eyes.
What are the serious risks associated with LASIK?
Serious risks for LASIK are extremely rare, and virtually do not occur in any eye center obeying routines of excellence. Unfortunate infection is an extremely rare occurrence, with a 1 in 2000-3000 chance (similar to any eye surgery). Fortunately, as the LASIK technique has developed over the years and proven to be of great benefit to millions of patients nationwide, firmly established protocols now exist which minimize the risk of infection

How long does LASIK take?
LASIK is generally performed as an outpatient procedure. Normally, Dr Khalil performs the entire process within about 10 minutes for BOTH eyes! The ultra-LASIK or iLASIK procedure takes a longer time as it involves additional steps applying the femto-laser system
What kind of anesthesia is used during LASIK? Does laser vision correction hurt?
Anesthetic eye drops are used. No needles or intravenous drugs are used. You will feel no pain during the surgery. You will feel pressure on and around the eye, but you will never, at any time, experience any pain.. With modern techniques, there is very rarely more than a mild discomfort for 12 hours.
Will I have both eyes done in the same time?
Surgery can be performed on both eyes at the same time, and in fact, this is prefered because it takes away the troublesome effects of being nearsighted/farsighted in only one eye. However, you may elect to have one eye done at a time.
What about long term results? Can my eyes deteriorate in the future?
Since 1988, over one million laser vision correction procedures have been performed around the world. There is no evidence of anything that would adversely affect long-term health of the eye.
Will I be able to see anything during this procedure?
Yes. During the procedure you will be asked to look at a blinking light. This will help to maintain proper alignment of the eye during the procedure.
What if I move during the procedure?
Patients worry about this a great deal, and their fear is largely unnecessary. Modern equipment and machines use ultrafast tracking systems, faster than any motion the human eye can make. So if your eye move during the procedure, the laserr machine and the laser beam can folow your eye in its movement. If your movement is extreme to the extent that it does not allow for proper laser delivery, then the mahine stops laser delivery altogether. The main disadvantage of eye movement during laser vision correction is not compromising the result, but lenghthening the time of the procedure as the laser machine waits your eye to be back in proper position, extending the time you spend in the laser room extra-minutes.
What if I blink during the lasik procedure?
Your eye will be held open by a device called a speculum. You will not be able to blink, and it is best to relax your eye muscles so that you do not feel any discomfort
Will there be any restrictions on my activities after excimer laser treatment?
There are no restrictions on your activities except that you will be asked to avoid rubbing your eyes during the first week or so. You should not resume activities like driving until your vision is adequate, which is usually achieved by most people by the second day. Touch sports; like diving are better avoided for 3 weeks.
How soon can I use eye makeup after lasik?
You may begin using eye makeup again 1 week after surgery. However, it is STRONGLY recommended that you purchase brand new eye makeup, specifially mascara, to avoid a potential infection.
If I don't get perfect (20/20) correction, will I be able to wear contacts after laser vision correction?
Few patients do not get a full correction with laser vision correction and will want to wear contact lenses. The general rule is: If you could wear contact lenses before the procedure, you should be able to wear them afterward. If you were unable to wear contacts before the procedure, then you probably will not be able to wear them afterward. There are some exceptions to this rule. After surgery the cornea has a slightly different shape, so some patients who could wear contacts before the procedure will not find an adequate fit after. However, because there are so many contacts now available, this would be exceedingly rare. More often, the opposite is true: Some patients can wear thin contacts after the excimer procedure who could not tolerate the thick lenses that were necessary before the procedure.
Will I need to use glasses again after LASIK?
The goal of the surgery is to reduce the person's dependance on lenses of any kind. However, many people still benefit from reading glasses, and many people will wear a thin pair of glasses for night driving.
If I don't get a perfect (20/20) correction, will I be able to have a repeat procedure to improve the results of LASIK?
If you have an undercorrection (with nearsightedness remaining), or an overcorrection (resulting in farsightedness) then a repeat procedure can be performed to improve your vision. In rare cases, when patients originally have irregularity in the cornea, they may respond better to repeat treatment.
How soon can I bathe or have a shower after lasik?
You can bathe or shower the same day as the lasik. As always, please avoid getting soap and water directly into your eye. Also, avoid rubbing your eyes for the first month after surgery.
How soon can I use computer and watch TV?
Non-contact sports can be resumed as soon as you wish. Swimming and strenuous contact sports such as boxing, football, karate, etc. should not be attempted for at least four weeks after surgery. Eye protection is always recommended for racquet sports or other rough sports where the risks of getting hit in the eye are high. You should stay out of swimming pools for one week, and lakes, rives, and oceans for two weeks following surgery.

can I wear contacts again after lasik?
Yes, but after few weeks. Many people like to wear colored contacts after their operation, and this can usually be done safely about 3 months following lasik. In other rare occarions, if there is any under- or over-correction, this can be temprarily corrected by contacts, again some months after lasik
