How old do you have to be to get lasik?
In the United States, the FDA has approved LASIK for age 18 or 22 and over because the vision has to stabilize. More importantly the patient's eye prescription should be stable for at least one year prior to surgery. The patient may be examined with pupillary dilation and education given prior to the procedure. Before the surgery, the patient's corneas are examined with a pachymeter to determine their thickness, and with a topographer, or corneal topography machine, to measure their surface contour. Using low-power lasers, a topographer creates a topographic map of the cornea. The procedure is contraindicated if the topographer finds difficulties such as keratoconus The preparatory process also detects astigmatism and other irregularities in the shape of the cornea. Using this information, the surgeon calculates the amount and the location of corneal tissue to be removed. The patient is prescribed and self-administers an antibiotic beforehand to minimize the risk of infection after the procedure and is sometimes offered a short acting oral sedative medication as a pre-medication. Prior to the procedure, anaesthetic eye drops are instilled. Factors that may rule out LASIK for some patients include large pupils, thin corneas and extremely dry eyes.

Who Invented LASIK Eye Surgery?
A prominent Russian eye surgeon, Dr. Svyatoslav Fydorov, was treating a severely nearsighted young boy who had fallen and gotten shards of glass stuck in his eye. Fortunately, the damage was minimal; a sliver was shaved off the cornea – the clear tissue that forms a protective layer over the eye. Following the accident the boy noticed a vast improvement in his vision. Dr. Fyodorov examined the child’s eyes and discovered that the tiny cuts made by the glass had reshaped the cornea and corrected the child’s focus. The doctor became exceedingly intrigued with this unforeseen discovery that he continued to study the matter and published his findings. It was not until a few American doctors with ample funding that the serious research began, bringing the procedure to the U.S. after observing the results in the former U.S.S.R. This is the manner in which the original All Laser LASIK vision correction began. They used a scalpel to create the cuts, calling the procedure Radial Keratotomy. Ultimately, the scalpel would be replaced with a laser, resulting in the laser eye surgery that we now call All Laser LASIK.
When was lasik eye surgery discovered?

An ophthalmologist is a physician who specializes in ophthalmology. The credentials include a degree in medicine, followed by additional four to five years of residency training in ophthalmology. Residency training programs for ophthalmology may require a one-year internship with training in internal medicine, pediatrics, or general surgery. Additional specialty training (or fellowship) may be sought in a particular aspect of eye pathology. Ophthalmologists are allowed to prescribe medications to treat eye diseases, implement laser therapy, and perform surgery when needed. Ophthalmologists may participate in academic research on the diagnosis and treatment for eye disorders.
What is an ophthalmologist?
Ophthalmologists are physicians ( MD/DO in the U.S. or MBBS in the UK and elsewhere or D.O. /DOMS/ DNB, not OD or BOptom) who have completed a college degree, medical school, and residency in ophthalmology. Training in ophthalmology equips eye specialists to provide the full spectrum of eye care, including the prescription of glasses and contact lenses, medical treatment, and complex microsurgery. In many countries, ophthalmologists also undergo additional specialized training in one of the many subspecialties. Ophthalmology was the first branch of medicine to offer board certification, now a standard practice among all specialties.
What is the Greek root for ophthalmology?
The Greek roots of the word ophthalmology are ὀφθαλμός ( ophthalmos, "eye") and -λoγία (- logia, "study, discourse"), i.e., "the study of eyes".

How much do you need to pay for Lasik surgery in India?
Laser or Lasik eye treatment in India can cost from 20,000 INR to 90,000 INR depending on factors such as type of clinic/Hospital you choose, Your city of residence and other associated treatments based on your conditions. Some centres may offer you a much lower cost, but you’ll tacitly be agreeing to the usage of inferior technology, lower involvement of the surgeon, and far less follow up care. Perhaps you might even not be satisfied by the results. Some centres offer a low price from appearances but the prices begin to rise steeply once you’ve been evaluated and treatment is finalised. Sometimes it would perhaps not even be a surgeon conducting your evaluation! Which, I believe, is the single most important step in the LASIK process because here accuracy is established by collecting data. So be very careful before you opt for a centre.

What are the complications of laser surgery?
Complications in Laser Surgery may only arise due to the following reasons: 1 Inflammation under flap (DLK): There may be various reasons for this condition. However, if not controlled, it can cause hindrance in healing or lead to loss of vision too. Lifting of the flap will be necessitated if such a condition arises for removing inflammation causing cells and prevent further damage to tissue. 2 Dry eyes: There are some patients who may experience dry eyes post laser surgery. For one, the patient must not suffer from continuous dry eye. Tear production may be reduced and blurred vision along with discomfort are common factors associated. This condition is experienced by close to half patients who undergo laser eye surgery. 3 Eye Health: A thorough check up with the doctor himself can prevent this problem. Patients shouldn’t have any complicated eye diseases such as corneal diseases, glaucoma, cataracts, and retinal or optic nerve diseases. Certain eye conditions like herpes, must also not exist prior to the procedure. 4 Contacts: Usage of Contact lens needs to be avoided prior to a LASIK procedure. The time duration of this can be decided by your medical practitioner, on a case by case basis. Corneal stability before your LASIK surgery procedure, is ensured by this. 5 Ingrowth in epithelium: LASIK surgery may lead to growth of cells from the cornea’s outer layer below the flap. Though this condition can be self-limiting, it may cause blurred vision or discomfort to some patients.

Patient Care: Often an optometrist or optician will carry out the initial assessments, which can help reduce the cost when compared to an assessment by the surgeon. Be a little cautious with this because it doesn’t allow you to build a professional relationship with the surgeon prior to your surgery. Which is often underestimated but an integral part of your comfort with the procedure?
Can lasik surgery be resolved?
Though LASIK surgeries show excellent success, complications may arise post treatment. These are rare and can be resolved with medical treatments or additional surgery. We understand your concerns about the process, although, you should know that it is relatively free from major medical problems.
Can you use contact lenses before lasik?
Contacts: Usage of Contact lens needs to be avoided prior to a LASIK procedure. The time duration of this can be decided by your medical practitioner, on a case by case basis. Corneal stability before your LASIK surgery procedure, is ensured by this.

Overview
LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea. LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity. For most people, LASIK provides a long-lasting alternative to eyeglasses or contact l…
Effectiveness
In 2006, the British National Health Service's National Institute for Health and Clinical Excellence (NICE) considered evidence of the effectiveness and the potential risks of the laser surgery stating "current evidence suggests that photorefractive (laser) surgery for the correction of refractive errors is safe and effective for use in appropriately selected patients. Clinicians undertaking photorefractive (laser) surgery for the correction of refractive errors should ensure t…
Risks
Higher-order aberrations are visual problems that require special testing for diagnosis and are not corrected with normal spectacles (eyeglasses). These aberrations include 'starbursts', 'ghosting', 'halos' and others. Some patients describe these symptoms post-operatively and associate them with the LASIK technique including the formation of the flap and the tissue ablation.
There is a correlation between pupil size and aberrations. This correlation may be the result of ir…
Process
The planning and analysis of corneal reshaping techniques such as LASIK have been standardized by the American National Standards Institute, an approach based on the Alpins method of astigmatism analysis. The FDA website on LASIK states,
"Before undergoing a refractive procedure, you should carefully weigh the risks and benefits based on your own personal value system, and try to avoid being influenced by friends that have had th…
Wavefront-guided
Wavefront-guided LASIK is a variation of LASIK surgery in which, rather than applying a simple correction of only long/short-sightedness and astigmatism (only lower order aberrations as in traditional LASIK), an ophthalmologist applies a spatially varying correction, guiding the computer-controlled excimer laser with measurements from a wavefront sensor. The goal is to achieve a more optically perfect eye, though the final result still depends on the physician's success at pre…
Topography-assisted
Topography-assisted LASIK is intended to be an advancement in precision and reduce night-vision side effects. The first topography-assisted device received FDA approval September 13, 2013.
History
In the 1950s, the microkeratome and keratomileusis technique were developed in Bogotá, Colombia, by the Spanish ophthalmologist Jose Barraquer. In his clinic, he would cut thin (one hundredth of a mm thick) flaps in the cornea to alter its shape. Barraquer also investigated how much of the cornea had to be left unaltered in order to provide stable long-term results. This work was followed by that of the Russian scientist, Svyatoslav Fyodorov, who developed radial keratot…
Further research
Since 1991, there have been further developments such as faster lasers; larger spot areas; bladeless flap incisions; intraoperative corneal pachymetry; and "wavefront-optimized" and "wavefront-guided" techniques which were introduced by the University of Michigan's Center for Ultrafast Optical Science. The goal of replacing standard LASIK in refractive surgery is to avoid permanently weakening the cornea with incisions and to deliver less energy to the surrounding ti…
