What is Lasik Eye Surgery

LASIK Eye Surgery

Those who are nearsighted, farsighted, or have astigmatism may benefit from LASIK, an acronym for laser in-situ keratomileusis, which refers to the procedure that corrects vision with the use of a laser.


LASIK is one of the numerous procedures that may correct your eyesight and works by reshaping your cornea, the transparent front portion of your eye, to direct light onto the retina, which is located in the rear of your eye.

Why Does Someone Have LASIK Done?

Your eyesight will become blurry if the light that reaches your retina does not concentrate on it the way it should. The medical community refers eye this as a refractive error. The following are the primary categories:

  • Nearsightedness (myopia) (myopia). When something is near you, you can see it clearly, but when it is far away, it seems hazy.
  • Farsightedness (hyperopia) (hyperopia). Those in the distance are more distinct to you, while those in the front are hazier.
  • Astigmatism. The shape of your eye might make it difficult to distinguish between different objects.

Have a discussion with your primary care physician to determine whether LASIK is the best option for you. You should not go through with the operation if any of the following applies to you:

  • Are less than 18 years of age
  • Are you pregnant or breastfeeding
  • Consume the appropriate drugs.
  • Have you recently made a lot of adjustments to your eyeglass or contact lens prescription?
  • Have corneas that are thin or irregular.
  • Have disorders that affect the eyes, such as glaucoma or dehydrated eyes
  • Have one or more other health conditions, such as diabetes, lupus, or rheumatoid arthritis

LASIK Eye Surgery Advantages

LASIK offers the following advantages:

  • It has been in existence for more than 25 years. After the procedure, about 96% of patients achieve their
  • desired level of vision. This figure has the potential to increase even more thanks to an enhancement.
  • There is little to no discomfort at all involved here.
  • There is neither a bandage nor any evidence of stitching.
  • If your eyesight changes as you age, your doctor may modify it.
  • After LASIK, you generally won’t need corrective lenses like glasses or contacts nearly as often, if at all.

LASIK Eye Surgery Hazards

LASIK, like any other surgical procedure, is not without its hazards, including the following:

  • This is an instead involved process. Even though it’s unlikely, certain conditions may leave a lasting mark on your eyesight. This is one of the reasons you should choose a surgeon with a great deal of expertise doing operations of this kind.
  • With LASIK, you have a minimal risk of losing your “best” correctable vision, which refers to the maximum degree of fabrication when using corrective lenses such as eyeglasses or contacts.
  • Most insurance doesn’t cover LASIK.

Complications Associated with LASIK Eye Surgery

After LASIK eye surgery, some individuals experience pain the first day or two following the procedure. Such adverse effects are relatively uncommon and often disappear over time. They are as follows:

  • Glare
  • The phenomenon of seeing halos around photographs
  • Having difficulty driving at night
  • The vision that is not constant
  • Dry eyes
  • Itchy and watery eyes
  • sensitivity to the light
  • You have some minor bruising on your watch.

What Should I Expect During My Pre-LASIK Follow-Up Visit?

A coordinator or an eye surgeon will visit you before your LASIK treatment to discuss what you may anticipate experiencing during and after the operation. In addition to doing a comprehensive eye exam, they will inquire about your past medical conditions. The thickness of your cornea, your refraction, and the pressure in your eyes may all be measured during this process. They may also dilate your pupils and create a map of your corneas. The surgeon will address any queries that you may have. After that, you can make an appointment for the surgical procedure.

Stop using your rigid gas-permeable contact lenses at least three weeks before you are scheduled for an exam if you currently use them. It is strongly recommended that you refrain from using any other contact lenses for at least three days before the assessment. Remember to bring your glasses to the appointment so the surgeon can assess your prescription.

On the day of your operation, eat a small breakfast before going in, and be sure you take all the drugs your doctor recommended. Avoid using eye makeup or oversized items in your hair that might get in the way of how your head is positioned. Call the doctor’s office first thing in the morning if you don’t feel well and inquire what you should do if you don’t feel well.

What Can You Expect From Your LASIK Eye Surgery?

Your eyes will be rendered numb with drops that your doctor will provide. You also have the option of requesting a light sedative.

To create a small flap in your cornea, they will either use a microkeratome or a femtosecond laser device. They will peel it back and then use another laser to alter the tissue behind it. After that, the flap will be reattached to its original position, and the operation will be finished.

The actual LASIK treatment itself takes roughly 20 minutes on average to complete. Make arrangements for someone to drive you home following the procedure.

After having LASIK eye surgery, what can I expect in terms of recovery?

Even though it may not seem like it, your eyes will get drier. Eyedrops with anti-infective and anti-inflammatory properties will be prescribed to you by your doctor, and they will also give you drops to keep your eyes moist. When you use them, you can have a momentary, mild burning sensation or a temporary blurring of your eyesight. Eyedrops should only be used after consulting with your primary care physician.

Your eyes will likely recover quite fast. The majority of patients see improved eyesight after a short period. You should contact your doctor if you have any issues or odd side effects.

After surgery, you won’t be able to utilize a hot tub or swim for the next two weeks. It is recommended that you purchase a plastic shield to use over your eyes when you sleep for the next several days.

Your primary care physician will let you know when you need to return for further appointments. The first one will likely occur between one and three days following the treatment.

With LASIK, there is a possibility that your eyesight may improve. As you become older, you may need to start using reading glasses. More than ten percent of patients require a second LASIK operation at some point in the future to get the desired results. However, with LASIK surgery, the vision of the vast majority of patients is improved to a level between 20/20 and 20/40.

LASEK Eye Surgery


The LASEK EYE surgery combines many of the advantages that are associated with several other vision-correcting procedures.

LASEK, which stands for laser epithelial keratomileusis, is a technique that combines the advantages of the two procedures that are done the most frequently: LASIK and PRK. The LASEK procedure is an eye surgery that may be performed to cure nearsightedness, farsightedness, or astigmatism.

What Are Some Benefits Along with LASEK Eye Surgery?

Some people believe that LASEK surgery offers several benefits, including the following:

  • There is no need to worry about the complications that might arise from making the flap in the cornea and then reattaching it.
  • The likelihood of experiencing dry eye after LASEK eye surgery is lower than that of LASIK eye surgery.

During LASEK eye surgery, various procedures are used to preserve the skinny layer of cells (epithelium) that covers the corneal surface. This layer is necessary to restore the cornea after the laser sculpting procedure has been carried out. When LASIK is performed, a laser or a mechanical instrument called a microkeratome generates a larger flap on the cornea, which is then subjected to laser sculpting.

What Are Some of the Drawbacks Along with LASEK Eye Surgery?

The following are some of the drawbacks associated with LASEK eye surgery:

  • Recovery of vision takes much longer than with LASIK eye surgery. During the healing process after
  • LASEK eye surgery, many patients will not have an utterly functional image for at least one to two weeks, comparable to the recovery period that patients experience following PRK eye surgery. Those who have had LASIK surgery often have improved vision within a day following the procedure.
  • The LASEK eye surgery often produces more significant pain and discomfort than the LASIK eye surgery, although the PRK eye surgery may cause less pain overall.
  • After LASEK eye surgery, patients are required to wear what is known as a “bandage contact lens” for around three to four days to serve as a protective covering between their blinking eyelids and the treated eye surface. This step is not required after LASIK eye surgery.
  • After LASIK eye surgery, patients must continue using topical steroid drops for several weeks longer than usual.

What Are the Potential Complications Associated with LASEK Eye Surgery?

Among the potential adverse consequences are the following:

  • A feeling similar to that of having something strange lodged in your eye (lasts anywhere from one to four days)
  • The vision that is temporarily impaired due to the low lighting circumstances (up to 12 months)
  • For dry eyes, needing you to apply drops to moisten them (up to six months)
  • The vision that is hazy or foggy (should disappear within six to nine months)

How Can I Determine Whether the LASEK Eye Surgery Is Right for Me?

Patients with incredibly steep or skinny corneas, which makes it difficult for the physician to construct a right flap during LASIK eye surgery, may benefit more from LASEK eye surgery. Patients participating in professional or recreational sports that place their eyes at an elevated risk for damage (such as boxing) may be better suited for LASEK eye surgery because traumatic injury to the eye is more significant after LASIK eye surgery than after LASEK eye surgery. Eye surgery, known as LASEK (or PRK), may be preferable for patients who suffer from dry eye syndrome. This is because the corneal nerves responsible for the tearing reflex are not severed during LASEK (or PRK) eye surgery.

What Can I Expect During My Preparation for LASEK Laser Eye Surgery?

Before your LASEK laser eye surgery, you will meet with an eye surgeon or coordinator. At this meeting, the eye surgeon or coordinator will review what you anticipate experiencing before and after the laser eye surgery. At this appointment, your eye health and medical history will be examined, and your blood pressure will be measured. The measurement of corneal thickness, refraction, corneal mapping, eye pressure, and pupil dilation are all tests that are likely to be performed. When you have completed the assessment that was performed on you, your surgeon will address any questions or concerns that you may have. After that, you can make an appointment to have the surgery done.

If you use contact lenses that are gas permeable and hard, you shouldn’t wear them for at least five to seven days before your examination. Other contact lenses, such as regular soft contacts, must be removed at least three days before the investigation.

On the day of your LASEK laser eye surgery, eat a light breakfast before heading to the doctor, and be sure to take all of the medicines your doctor recommended for you. You must not use eye makeup and do not have any cumbersome items in your hair that might prevent you from adequately situating your head beneath the laser. If you wake up feeling unwell on the day of the surgery, you should contact the doctor’s office to see if the treatment may be moved to a later date.

What Can You Expect From Your LASEK Eye Surgery?

Eye surgery, known as LASEK, is performed while the patient is sedated with a topical anesthetic injected directly into the eye. During the operation, the outermost layer of cells, known as the epithelium, is cleaned with alcohol for approximately a minute and a half before peeling away from the tissue underneath it. After that, the eye doctor will either raise it or roll it back so it may reach the tissue of the cornea. Laser refractive surgery, also known as LASIK and PRK, uses the same kind of laser to treat newly exposed tissue. After that, the uppermost layer of cells is positioned correctly.

This is in contrast to LASIK eye surgery, which involves creating a flap in the cornea using a laser or other equipment that cuts tissue. In contrast to PRK, which involves scraping away the top layer of cells and then waiting for new ones to sprout in their place, LASEK eye surgery consists in leaving the top layer of cells alone. It is thought that this makes the healing of the cornea easier while causing less pain than PRK does; nevertheless, it also produces greater blurriness in the eyes during the first few days compared to PRK.

What Should You Expect After Your LASEK Eye Surgery?

Expectations for vision correction after LASEK eye surgery are comparable to those after LASIK. The flap generated during LASEK eye surgery typically heals within approximately four to seven days. The patient usually wears a specialized contact lens that functions as a bandage for up to four days following the procedure. In addition, patients who have LASEK eye surgery may feel discomfort in their eyes within the first day or two after the procedure.

Patients with LASIK surgery often see an improvement in their vision within a few days after the treatment. On the other hand, the LASEK eye surgery might take as much as a week to complete.

The day following your LASEK eye surgery, you will go back to the doctor for an examination. In most cases, you will also have follow-up appointments one week and three months after surgery.

When to Worry About LASEK and Contact the Doctor

Contact your eye doctor as soon as possible if you are experiencing discomfort, a sudden loss of vision, red eye(s), or discharge from your eye(s) after your LASEK eye surgery. In addition, your eye doctor should be contacted if you have any concerns about the procedure.

How to Take Care of Your Eyes After a Laser Eye Procedure?

After having laser eye surgery, you should take the following measures to avoid being hurt or getting an infection:

  • Wait to wash your hair or shower until the next day after the event.
  • During the first few days following surgery, you should do your best to avoid getting the water that isn’t sterile into your eyes. This includes water from showers, washing your hair, and other similar activities.
  • Take extra precautions to ensure your safety while you’re in the bathroom. As you wash your hair, be sure that you don’t get soap in your eyes, and you should also be careful with hair spray and shaving cream.
  • Please refrain from rubbing your eyes for at least one whole month.
  • Be sure to use all the eye drops, including the artificial tears your doctor recommended.
  • Only drive if you feel comfortable. First things first: get your doctor’s approval.
  • During the first week, when you sleep, you should wear the eye protection or goggles that the doctor provided you.
  • You should avoid getting any water from the faucet into your eyes for at least a week.
  • You should stay away from lakes, pools, whirlpools, and saunas for at least three weeks.
  • Please wait at least a week before applying eye makeup again. To prevent illness, throw away any goods that are only partially used.
  • You should wait ten days before getting your hair dyed or permed again.
  • No physical activity over the next two days.
  • After you’ve started working out and participating in sports again, safeguard your eyes by wearing eye protection for at least a month.
  • Your eyes may be more sensitive to light for a short period. Sunglasses with a dark lens are helpful.
  • Stay away from unclean and dusty places over the next week.
  • Using sunglasses during sunny days for at least a year is recommended to reduce the risk of scarring caused by the sun.

When Should I Make an Appointment with a Doctor?

Make an appointment with your primary care physician as soon as possible if you have any of the following symptoms: discomfort, a sudden reduction in vision, redness, or discharge from your eye.

The LASIK Eye Procedure in Addition to Other Refractive Surgeries

Several kinds of refractive surgery

Three distinct approaches to refractive surgery may be used. They are as follows:

  • Excimer laser techniques (including LASIK surgery, LASEK, and others)
  • Artificial lens implants
  • Incisions made in the cornea and incisions made in the limbal tissue to relax them

The LASIK procedure is performed using an excimer laser.

The excimer laser, which was developed in the 1980s and is controlled by a computer, enables eye surgeons to remove specific quantities of tissue from the cornea, which in turn allows the cornea to be molded in order to create predictable changes in the patient’s field of vision. Laser-assisted surgeries like LASIK benefit from this since it ensures high safety and accuracy throughout the surgery.

The Procedures Included in LASIK Surgery

“laser-assisted in situ keratomileusis” is the full name for the procedure, abbreviated as “LASIK.” The following are some of the stages involved in LASIK surgery:

  • Before the procedure, your eyes will be treated with drops that numb them.
  • Holding the eyelid in place using an eyelid holder inhibits blinking and keeps the eye open.
  • A suction ring is put on the eye to prevent the eye from moving and to elevate and flatten the cornea.
  • A flap is created in the cornea by the ophthalmologist performing the procedure. The surgeon may use a femtosecond laser or a surgical blade known as a microkeratome during the process. When the flap is folded back, the central portion of the cornea is exposed (stroma).
  • The excimer laser is used to shape the tissue of the cornea that is exposed.
  • The corneal flap is then reattached to its proper position. It just takes a few minutes and does not need stitches to repair itself.
  • Eye drops are used to facilitate the healing process.

Following surgery, you can feel like your eyes are itching, burning, or inflamed. This clears up on its own after a day or two, most of the time. It is crucial to refrain from rubbing your eyes since doing so might cause the flap to dislodge. You will likely see an improvement in your vision the next day; however, it may take anywhere from three to six months for your eyesight to settle ultimately.

Protocols Connected with the LASIK Operation

Medical professionals have created several surgical procedures similar to the LASIK technique. They include the items listed below.

  • LASIK using a wavefront-guided approach The laser therapy is directed by a “map” that contains specific information about the path that light takes through the eye. This reveals even the most minute variations in the focus of the image. The objective is to lessen patients’ likelihood of issues after surgery, such as glare, light “halos,” fuzzy vision, and impaired night vision.
  • The procedure known as PRK (photorefractive keratectomy) may treat moderate to severe cases of nearsightedness, astigmatism, and mild to moderate cases of farsightedness. The ophthalmic surgeon removes the epithelium (surface cells on the cornea). The surgeon then uses the excimer laser to reshape the cornea. After the surgery, a “bandage contact lens” is applied to facilitate the healing process. The first week of recovery is when initial healing takes place, and you may experience some pain during this time. It might be weeks or even months before you regain your complete vision. As a result of these factors, LASIK surgery has primarily taken the role of PRK surgery. The only exceptions to this are individuals whose corneas are too thin for LASIK surgery and those with certain lifestyles or vocations (such as professional athletes).
  • PRK and LASEK, for laser epithelial keratomileusis, are highly comparable procedures. The epithelium is peeled off and reattached when the operation is finished, which distinguishes this procedure from others. LASEK is a procedure that, like PRK, may be advised for those with thin corneas. Similar to PRK, the healing process may entail some degree of pain.
  • The corneal flap that is created during Epi-LASIK is made using a specialized tool called an epi-keratome, which is placed on the layer of cells that cover the cornea (epithelium). Epi-LASIK is often reserved for individuals unable to undergo the regular LASIK surgical procedure.

Surgery for Implantable Contact Lenses

Implants are essential to the success of some different forms of refractive surgery. The following activities are included in these procedures:

  • Intacs implants are placed into the intrastromal layer of the cornea.
  • Intraocular lenses (IOLs), phakic intraocular lenses (IOLs), accommodative intraocular lenses (IOLs), multifocal intraocular lenses (IOLs), toric intraocular lenses (IOLs) for correcting astigmatism, also known as refractive lens exchange or precise lens extraction.
  • Implantable Collamer Lens (ICL) implants
  • The following describes each implant.
  • Implants are known as intrastromal corneal ring segments (INTACS). It is common practice to insert semicircular bits of plastic into the cornea. These things are referred to as INTACS (intrastromal corneal ring segments). They alter the cornea’s curvature and adjust the patient’s focusing ability. INTACS are implanted by making a very tiny incision in the cornea. The incision is closed using either two small sutures, sometimes known as stitches, or specialized tissue glue. After two to four weeks, the sutures are routinely removed. It is possible to do away with INTACS if that becomes required. After a few weeks, the cornea will have returned to its natural form. They became available just about the time when LASIK became the most common surgical method for treating myopia (nearsightedness). In refractive surgery, LASIK and other similar treatments have largely supplanted INTACS. The corneal deterioration known as keratoconus is the primary indication for using INTACS.
  • Phakic IOLs. Those with a degree of nearsightedness or farsightedness that prevents them from safely using an excimer laser may use these instead. The operation is similar to cataract surgery, with the critical difference being that the patient’s natural lens will not be removed. The eye surgeon will put a vision-correcting lens in front of the patient’s natural lens. These lenses may be composed of silicone, plastic, or a mix of plastic and collagen called Collamer. Phacoemulsification intraocular lens surgery is considered more intrusive than laser-assisted in situ keratomileusis (LASIK). This aspect must be weighed against the advantages enjoyed by those who have very high prescriptions for their eyeglasses or contact lenses but cannot undergo laser surgery.
  • Refractive lens exchange, accommodative intraocular lenses (IOLs), multifocal IOLs, and toric (astigmatism correcting) IOLs. These implants can correct presbyopia, nearsightedness, farsightedness, and astigmatism in patients. The patient’s natural lenses are removed during surgery, and in their place, artificial lenses that correct their vision are installed. There is no reshaping of the cornea performed.
  • EVO Implantable Collamer Lens (ICL). Depending on the patient’s specific needs, they may treat either nearsightedness, farsightedness, or astigmatism. The lenses, made of plastic and collagen known as collamer, are surgically placed between your natural lens and your iris. This allows your eye to maintain its standard shape while having clear vision.

Surgical Procedure to Alter the Shape of the Cornea

Radial keratotomy, sometimes known as RK, was the first refractive surgery performed in the United States. The LASIK surgical procedure has essentially supplanted it. A modification of the RK procedure, known as a limbal relaxing incision or arcuate keratotomy, could be recommended for patients with moderate cases of astigmatism. While making incisions in the cornea, the ophthalmologist will use a diamond-tipped scalpel. The cornea is reshaped and leveled out due to these incisions in RK. RK gradually compromises the eye’s structure, leading to fluctuations in vision and long-term instability; these are the fundamental reasons it is performed so seldom these days.

Who Is Eligible for LASIK Surgery and Who Is Not Eligible, as well as Other Refractive Procedures?

After consulting with a refractive specialist, anybody thinking about having LASIK or another kind of refractive surgery should choose only after doing so. General criteria include:

  • Being age 18 or older
  • Maintaining good eye health
  • Having gone the previous three years without requiring a new prescription for either eyeglasses or contact lenses
  • We possess eyesight that can be improved with the use of refractive surgery.

Those who fall into any of the following categories may not be good candidates for most types of refractive surgery:

  • Have a history of a pre-existing eye condition or a family history of a specific eye illness, most notably keratoconus, a disease that affects the cornea.
  • Use the prescribed medications known to influence eyesight or the healing of the cornea.
  • Are you pregnant or breastfeeding?

Always be sure to question your surgeon about the advantages as well as the potential hazards of the procedure. In this manner, you can make a more informed choice. There is a better chance that the result will live up to your anticipations.

The Price Tag Attached to LASIK Surgery

Laser refractive surgery often comes with prices ranging from $1,500 to $3,500 for each eye. The use of wavefront technology or the “laser microkeratome” increases costs. Treatments in practice where a skilled eye surgeon assesses the patient before surgery, carry out the procedure and monitors the patient afterward often come with a higher price tag. The price varies from one place to the next.

Be sure that your surgeon explains everything that is included and not included in the price you are being given. Inquire about the additional costs that may be incurred for treatment or follow-up visits if issues arise.
