Types Of Laser Eye Surgery

Implementation In The Us

Types of Laser Eye Surgery Treatments

The LASIK technique was implemented in the U.S. after its successful application elsewhere. The Food and Drug Administration commenced a trial of the excimer laser in 1989. The first enterprise to receive FDA approval to use an excimer laser for photo-refractive keratectomy was Summit Technology .In 1992, under the direction of the FDA, Greek ophthalmologist Ioannis Pallikaris introduced LASIK to ten VISX centers. In 1998, the “Kremer Excimer Laser”, serial number KEA 940202, received FDA approval for its singular use for performing LASIK. Subsequently, Summit Technology was the first company to receive FDA approval to mass manufacture and distribute excimer lasers. VISX and other companies followed.

Pallikaris suggested a flap of cornea could be raised by microkeratome prior to the performing of PRK with the excimer laser. The addition of a flap to PRK became known as LASIK.

Laser Treatment For Glaucoma

While there is no cure for glaucoma, there are several approaches to managing the condition to reduce eye pressure and keep your vision for as long as possible. Most glaucoma treatments involve eye drops that reduce inner eye pressure, but sometimes, your eye needs additional help regulating how much aqueous humor moves in and out. Lasers are now used on various parts of the eye to create small, temporary drains so internal eye pressure lowers.

Prk Or Photorefractive Keratectomy

PRK was the first laser eye surgery method, its been available since 1988 and was approved by the FDA in 1995. Although LASIK has largely replaced it, it continues to be used to treat people with thin corneas.

Its a blade-free technique for treating and correcting myopia and astigmatism, but its not appropriate for moderate to severe hyperopia . PRK was the first type of laser eye surgery for vision correction and is the forerunner to the well-known LASIK procedure. Even the same excimer laser that is used in LASIK is used in PRK.

PRK works similarly to LASIK in that it reshapes the cornea, but the reshaping is done on the surface after the epithelial cells are removed.

One of the main differences between LASIK and PRK surgery is that no corneal flap is created during PRK surgery. PRK may be a better option than LASIK for patients with thin corneas or active lifestyles because there is no corneal flap.

The frontal layer of the cornea is removed at the start of treatment to allow the laser to reshape the stromal layer deeper into the cornea. The laser vaporizes parts of the cornea, guided by an extremely accurate computer, to give it a different shape that is corrected for its vision. A bandage contact lens is used at the end of the laser treatment.

PRK recovery takes a little longer than LASIK recovery. Whereas LASIK recovery takes only 4-5 hours, PRK recovery can take 4-5 days and the final improvement takes 3-4 weeks.

Is Laser Eye Surgery Permanent

LASIK, ASLA, SMILE®/SMILE® pro permanently reshape the cornea. Some people may require a follow-up procedure to enhance or improve the initial results. Its important to be aware that presbyopia can develop at around 4050 years of age. Presbyopia is an age-related condition of your lens, which reduces your ability to focus on near objects and will occur regardless of whether you have laser eye surgery or not. Presbyopia does not involve the cornea.Laser eye surgery will not prevent the development of presbyopia, although it is sometimes used to delay the need for glasses.

How Many Aftercare Appointments Are Required Following Laser Eye Surgery

  • 12 weeks after surgery, and
  • 23 months after surgery.

Patients who have undergone PRK generally have aftercare appointments:

  • On the same day or the day after surgery
  • 35 days after surgery to remove the bandage contact lens
  • 2 weeks after surgery

Types Of Corrective Eye Surgeries

Refractive surgery refers to procedures that correct refractive errors, which include:

  • Myopia. Also called nearsightedness, this causes blurry distance vision but clear vision up close.
  • Hyperopia. Also called farsightedness, this is when nearby objects are blurry and distant ones are clear.
  • Astigmatism. This is when the eye is oval-shaped instead of round, causing blurry vision near and far.

Refractive surgery is usually done as an outpatient procedure.

The Cornea And Laser Eye Surgery

The cornea is the transparent dome of tissue at the front surface of the eye. In addition to the crystalline lens located behind the coloured iris inside the eyeball, the cornea is responsible for focusing light through the eye.

When light doesnt come to a sharp focus on the retina, we then perceive this as unclear vision. However, by adjusting the shape and curvature of the cornea through laser vision correction, your eye surgeon can redirect the way that light bends through this structure.

All types of laser eye surgery are based on the premise of reshaping the cornea.

Astigmatic Keratotomy And Limbal Relaxing Incisions

These procedures also include making incisions on the cornea to flatten the tissue. Astigmatic keratotomy and limbal relaxing incisions correct lower levels of astigmatism. Theyre often performed after cataract surgery or corneal transplants.

The surgeon makes incisions where the cornea is steepest. LRIs are more common than AK. One reason is that LRI incisions are closer to the edge of your cornea, resulting in better vision and less glare.

Now, these procedures may be replaced with laser refractive surgery or toric intraocular lens implants.

Good visual function is achieved within 2448 hours with LASIK and SMILE/SMILE pro but may take up to 2 weeks with PRK .If surgery was routine and successful, contact sports may be resumed:

  • within 1 week of undergoing SMILE/SMILE pro
  • 24 weeks following PRK
  • 1 month after LASIK surgery.

For advice on your particular circumstances, speak to a surgeon.

What Happens During The Procedure

Your ophthalmologist will use eye drops to numb your eye and to make the pupil large. A special contact lens is put on your eye to help direct the lasers high-energy beam of light at the capsule behind the implant lens in your eye. The laser makes an opening in the capsule. You will see a few brief flashes of light and feel little, if any, discomfort. The procedure usually takes less than 5 minutes. You will be able to go home soon after it is done.

Complications In Laser Surgery May Only Arise Due To The Following Reasons:

  • Inflammation under flap : 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.

  • 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.

  • Eye Health: A thorough check up with the doctor himself can prevent this problem. Patients shouldnt 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.
  • 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.

  • Ingrowth in epithelium: LASIK surgery may lead to growth of cells from the corneas outer layer below the flap. Though this condition can be self-limiting, it may cause blurred vision or discomfort to some patients.

How Long Does Lasik Last

In theory, laser vision correction is a permanent surgery that should technically last a lifetime. The surgery corrects the current vision problem, but your eyes will continue to change over time, whether youve had surgery or not.

So, although the surgery can correct your original vision problem, you may develop other vision changes afterward, especially if you had laser surgery at a young age.

One study found that 94% of people who had laser surgery for vision correction were able to avoid using physical correction tools such as glasses and contacts even 5 years later. However, about 1 in 10 people who have laser surgery need follow-up procedures to get the best results.

A Modern Perspective On Laser Eye Surgery


Medical science is always advancing, and as such, new innovative technologies and methodologies are emerging for laser eye surgery all the time. Wavefront technology, for example, takes exceptionally precise measurements of the eye specifically the curvature of the cornea. These specific measurements allow the doctor to correct your eye with more accuracy, shaping your cornea in a way that is custom to you and your eyes, rather than simply replicating your prescription, which is not.

There are eye procedures that are completely bladeless, procedures to replace the lens of your eye, and even procedures specifically designed for those with thin corneas in mind. In a matter of 3 decades, laser eye surgery has become almost completely customizable, making it simpler than ever to get accurate, long-lasting vision correction.

How Does Laser Surgery In The Eye Work

Before your procedure, your surgeon will review your needs and any specific risks you may have, take measurements of your eyes, and give you specific instructions for the surgery.

On the day of surgery, you should dress comfortably and plan for an outpatient procedure with someone to drive you home afterward. Although the time the procedure takes can vary by person and location, laser vision correction usually takes about 30 minutes per eye.

Heres what you might expect during laser vision correction surgery:

  • A healthcare professional will administer eye drops to numb your eyes.
  • They will place an eyelid holder with a small suction cup over your eye to hold your eye steady and keep you from blinking. This may feel like a finger pressing over your eyelid, and your vision will be dim or black.
  • Your surgeon will use a laser to create a thin flap of tissue in your cornea and fold it back.
  • Your surgeon will ask you to stare straight ahead at a target light while they use another laser to reshape your cornea. This laser is programmed to correct your vision problem based on specific measurements taken before your procedure. During this portion of the surgery, you may hear a clicking sound.
  • When the reshaping is complete, your surgeon will put the corneal flap back into place and finish the procedure.
  • Any surgery carries a risk of some form of complication, and laser eye surgery is no exception. Possible complications or side effects of laser eye surgery include:

    Phakic Intraocular Lens Implantation

    With PIOL artificial lenses are placed in your eyes without removing your own natural lenses. It’s a bit like building contact lenses into your eyes.

    Because the lens is inside your eye, you can do things you could not normally do in contact lenses, such as swimming or water sports.

    Who is it suitable for?

    PIOL can be a good option for younger people who are not able to have eye laser surgery, perhaps because they have a high eye prescription or a high degree of astigmatism. Later in life, RLE may be a better alternative.

    What does PIOL involve?

    The surgeon makes a small cut in the surface of your eye and slips the news lens in through this. No stitches are needed.

    Are there any risks?

    Your surgeon will discuss any side effects and risks with you before you go ahead with surgery.

    It’s normal to get some disturbance in your vision after PIOL but this should gradually settle down. Glare from oncoming headlights while driving at night is common to begin with.

    The surface of your eye may feel uncomfortable for a while. You may also have red blotches on the white of your eye for few weeks.

    Serious complications are rare and, if you do have any problems after surgery, they can usually be corrected. Cataracts may develop earlier in life after PIOL.

    Refractive lens exchange

    RLE is basically the same as cataract surgery. The natural lens in your eye is removed and replaced with a new, artificial one.
