LASIK eye surgery

LASIK eye surgery
LASIK is a surgical procedure intended to reduce a persons dependency on glasses or contact lenses LASIK stands for LaserAssisted In Situ Keratomileusis and is a procedure that permanently changes the shape of the cornea the clear covering of the front of the eye using an excimer laser A knife called a microkeratome is used to cut a flap in the cornea A hinge is left at one end of this flap The flap is folded back revealing the stroma the middlesection of the cornea Pulses from a computercontrolled laser vaporize a portion of the stroma and the flap is replaced
The surgery improves the vision in patients who have nearsightedness farsightedness and astigmatism LASIK surgery usually takes less than one minute per eye Treatment involves reshaping the cornea the protruding portion of surface of the eye to improve vision A large percentage of nearsighted farsighted and astigmatic patients are potential candidates for LASIK Patients who are 18 years of age or older have healthy eyes that are free from retinal problems corneal scars and any eye disease are suitable Along with being medically suitable the best candidates are people with a lifestyle or occupation in which they are dissatisfied with their contact lenses or glasses By having an evaluation examination and consultation with you the doctor will be able to determine if you are a good candidate

Advantages of LASIK surgeryThe LASIK technique takes less than 30 minutes to perform and is very effective The technical advancements incorporated in the LASIK technique eliminates the clinically significant risks leading to visual impairment after a refractive surgery Most surveys show that 9298% of people who undergo the surgery are satisfied with the results The LASIK surgery done on the most sensitive part of the eye and is not reversible Even after a LASIK surgery a person may require reading glasses during midlife The moments after a major lifealtering event are usually filled with joy laughter and camaraderie but this usually doesnt happen after surgery LASIK surgery is no different than any other surgery but its drawbacks may be a little different than others The results of LASIK surgery are much akin to the results of being pestered by a pet day after day Instead of the healing of bruises or incisions LASIK surgery is accompanied by more burning and itching of an area that you are completely unable to scratch or cool At this point any touching of the eye could undo everything the surgery just repaired Your vision will be blurry because of the watering and tearing up of your eye but you cannot under any circumstances touch your eye The eye may appear dry or bloodshot for several days if this occurs you should consider taking time off of work If you experience severe pain from LASIK surgery at any time you should contact your surgeon Within 24 to 48 hours after your surgery you should have a postoperative exam to make sure everything is healing well At regular intervals after the LASIK surgery up to six months you should continue seeing your doctor for checkups At the first visit after LASIK surgery your doctor will remove the shield and make sure your eye is responding correctly to the surgery You will not be able to use contact lenses for sometime to keep from further irritation and you may have to use drops or artificial tears to help with lubricating the eye

The possibility of complications or imperfect vision after LASIK vision correction can be greatly reduced if you simply find out if you are a good prospect for the surgery Not everyone who wants LASIK vision correction is necessarily a good candidate to have the surgery You should consider a few things before you settle on LASIK If you dont like to take a chance every now and then you probably shouldnt have LASIK vision correction There are possibilities of complications as a result of LASIK that you should research before having the procedure done If having LASIK vision correction could affect your career or is not covered by your insurance you should think of another alternative The cost of LASIK is getting cheaper but is still quite expensive and youll want to make sure it isnt prohibited by your employer You must be an adult with refractive stability to be accepted for LASIK vision correction Refractive instability is determined by patients who are 20 or younger with fluctuating hormones due to such things as diabetes or someone who is pregnant or breastfeeding or taking medications that cause fluctuation in vision Preparing for any type of surgery is an unenviable and tedious process You must make sure you have everything ready and your body in tiptop shape While preparing for LASIK eye surgery may not be quite as difficult there are some things you need to prepare for before LASIK You definitely need to stop wearing your contact lenses in the weeks leading up to your consultation before LASIK Since the surgery is dependent on the shape and measurement of your cornea you must let it regain its shape Lenses sometimes reshape the cornea themselves causing problems with LASIK

Soft contact lenses should be removed and not worn for at least two weeks prior to your LASIK evaluation Rigid gas permeable lenses should be removed and not worn for at least three weeks prior to LASIK evaluation Hard lenses should be removed and not worn for at least four weeks prior to LASIK evaluation When you meet the doctor to discuss LASIK eye surgery you should let him know a few things about yourself Let the doctor know about any past or present medical and eye conditions as well as all medications you are taking or are allergic to It is important that you disclose all of this to your doctor before deciding if LASIK is right for you After you have disclosed this personal information to the doctor you should then discuss if you are a good candidate for LASIK surgery Let him explain to you the risks benefits and alternatives of the surgery as well as what you can expect from beginning to end
You should stop using any lotions perfumes or creams the day before the surgery as well as any makeup that may cause debris to get in the eye The doctor may even request that you scrub and wash out your eyes for a good time before LASIK surgery to prevent the chance of any type of infection Finally you should definitely arrange with a loved one for transportation to and from the LASIK surgery Before LASIK surgery some doctors will arrange for you to take some medicine to help you relax that could impair your vision and reaction time After LASIK surgery you may need a few days to recover your vision hence the need to arrange for a drive home

LASIK has advantages over other procedures including a relative lack of pain afterward and the fact that good vision is usually achieved almost immediately or at least by the very next day LASIK Eye Surgery Laser vision correction gives most people the freedom to enjoy their normal daily activities without the dependence of corrective lenses It also allows people to pursue careers that they would not have been eligible for without excellent vision In general laser vision correction can make your life much simpler and more enjoyable An instrument called a microkeratome is used in LASIK eye surgery to create a thin circular flap in the cornea Another newer way of making the flap is with a laser The surgeon folds the flap back out of the way then removes some corneal tissue underneath using a laser The laser uses a cool ultraviolet light beam to precisely remove very tiny bits of tissue from the cornea to reshape it When the cornea is reshaped in the right way it works better to focus light into the eye and onto the retina providing clearer vision than before The flap is then laid back in place covering the area where the corneal tissue was removed.
