Posted by It has been more than two decades since excimer laser eye surgery, sometimes known as laser vision correction, first became popular. When this operation is performed, the requirement for glasses or contact lenses is reduced or eliminated entirely. In order to make an informed decision about laser eye surgery, you must be aware of the procedure’s basics, including what to expect as well as its advantages, dangers, and alternatives.
Candidates for Laser Eye Surgery who are in good health
Individuals who are myopic (nearsighted), hyperopic (farsighted), or/and have astigmatism, which is an abnormality in the surface of the front of the eye, the cornea, can benefit from laser vision correction. learn more about laser vision correction by clicking here
There are certain people who should not get laser eye surgery. If you meet the following criteria, you may be a candidate for this procedure:
- You are over the age of 18 years.
- You would want to lessen or eliminate the need for contact lenses or glasses in your everyday life.
- It has been at least a year since your eyesight has been unaffected.
- Surgery is not contraindicated in the case of ocular or medical contraindication.
- You are not barred from having this surgery because of your profession, career, or passion.
Precautions to Take Before Having Laser Eye Surgery
Certain medical conditions that may interfere with healing may preclude you from being a good candidate for laser eye surgery. Disorders such as collagen vascular illnesses, lupus, rheumatoid arthritis, and HIV-associated diseases can all have an impact on the correct healing of wounds, which is essential for achieving a successful outcome.
This technique may also be unsuitable for those who have dry eyes, Sjögren’s disease, uneven astigmatism, a high pupillary size, thin corneas, or corneal keratoconus (a cone-shaped cornea), among other problems.
It’s possible that you’ll still require glasses.
Laser eye surgery is intended to lessen or eliminate the need for corrective lenses such as glasses or contact lenses. Despite the fact that many patients are able to operate normally without the need for glasses or contact lenses, some nevertheless require optical correction for specific jobs. Furthermore, laser vision correction has no effect on the condition known as presbyopia, which is the predicted problem with close work when one approaches the age of 40 or older, as previously stated. Presbyopia can be reduced with the use of monovision laser operations, which entail having one eye corrected for distant vision and the other treated for up-close vision in one session.
What laser eye surgery Is and How It Works
Laser eye surgery is the abbreviation for the refractive laser operation that is most routinely done. To perform this procedure, an excimer laser is utilized to vaporize a little piece of corneal tissue after creating a very thin flap in the cornea and folding it back on its own hinge. The flap is then repositioned in its original position.
Laser eye surgery using wavefront guidance
Laser eye surgery and other refractive laser surgeries, like all other technologies, are always evolving and improving. There are now methods for tailoring the application of excimer laser removal of corneal tissue to each patient’s eyes, resulting in better and more predictable visual outcomes with fewer visual side effects than previously possible.

Laser eye surgery, PRK, Epi-LASIK, and LASEK are all types of laser eye surgery.
Photo-refractive keratectomy (PRK) is a procedure in which the excimer laser is used on the cornea instead of a LASIK flap is created. This method was developed prior to laser eye surgery and was mostly displaced by laser eye surgery, but it has recently re-emerged as a more advantageous option for patients who have thinner corneas or who have pre-existing dry eye conditions.
Implantable lenses have a high prescription strength.
A small percentage of people suffer from extreme nearsightedness (myopia) to the point at which laser eye surgery cannot fix their vision without drastically weakening the corneal tissue. For those who fall into this category, an artificial lens that is implanted into the front of the iris by a tiny incision may be an option. These plastic lenses have been authorized by the Food and Drug Administration (FDA) for the treatment of severe myopia. There are dangers associated with this procedure, including the possibility of visual loss.
Laser eye surgery has a number of risks.
It is important to remember that elective laser eye surgery is a surgical procedure and should not be conducted carelessly. As with any surgical procedure, there is the possibility of temporary or permanent damage to the eye. This can include things like blurred or distorted vision, haloes around lights, increased sensitivity to bright lights, glare, dry eyes, and the need to continue wearing glasses or contact lenses. It is also possible to lose your vision after laser eye surgery or PRK. You can read about Some preemptive measures to take before laser eye surgery by clicking here.
What to Look for When Choosing an Eye Surgeon
Carry out some preliminary research before selecting an ophthalmologist to visit with regarding laser eye surgery. This is a significant issue, and your selection should take into consideration more than just the price element. When it comes to eye surgery, personal recommendations, expertise, and actual outcomes are significantly more essential than viewing commercials on television or in the media.
The actual procedure of refractive laser eye surgery takes around 30 minutes. The pre-operative examination is vitally essential, and this will be carried out prior to your surgical session to ensure that you get the best possible outcome. The results of the tests performed before surgery will be utilized to make the necessary intraoperative decisions during the laser eye surgery itself. The eye(s) will be numbed with several drops before the surgery begins, and you will be laying down on an operating table. Most of the time, both eyes are operated on the same day. Following the procedure, you will be given specific instructions, including the usage of certain eye drops to aid in the healing process.
Preparing for a Surgical Procedure
Dry eye or inflammation may be reduced using eye drops prior to the laser eye surgery, depending on your ophthalmologist’s recommendations. You will also be given guidelines on when to quit using contact lenses as well as when to discontinue applying facial lotions and creams to your face.
Early Post-Operative Recuperation
Following your procedure, your ophthalmologist will want to visit you within 1 or 2 days. You will be given specific instructions on when you are permitted to drive and what activities you are not permitted to engage in. Following surgery, you may have slight pain or discomfort, a foreign body sensation in one or both eyes, variations in your vision from hour to hour, occasional visual blur, and weeping of the eyes.
