Can You Have Laser Eye Surgery Twice?

Laser eye surgery is a great solution when you’re struggling with poor vision. Sharp, focused distance vision is something that you can enjoy for years to come, but there are situations whereby you may notice a slight regression in the quality of your sight.

Albeit quite uncommon, there are instances where you may need re-treatment. There is a range of criteria that will need to be checked in order for you to continue with your second laser treatment and your suitability will be determined by an optometrist.

Although there are many factors that contribute to your suitability, many people aren’t aware of two of the most important:

. Thickness of the corneal tissue

. The amount of the corneal tissue that will need removing in the second re-treatment.

Alongside the two mentioned above, general eyesight, genetics and age play a big part in the healing process post-surgery. You may experience blurred vision or glare (particularly after LASEK treatment), but this generally subsides after a few weeks.

How Long Does Laser Eye Surgery Last?

The majority of patients enjoy the benefits of laser eye surgery for years, up until they require treatment to correct their reading vision (Lens Replacement Surgery). The muscles around your eye weaken as you age, which is a contributing factor to vision deterioration.

Reasons For Needing a Secondary LASIK Surgery

There are many reasons why a patient could need a secondary LASIK procedure. For example, your first surgeon may not have removed enough corneal tissue to correctly address your refractive error.  In more common cases, however, your vision may change over time due to natural aging. This is called presbyopia, and it occurs when your eye lens becomes less flexible over time. You may not be able to focus on nearby objects as well as in the past. If this is your situation, there are other ways to improve your eyesight without LASIK.

What Happens in A Laser Re-Treatment?

In your initial treatment, the surgeon will have removed corneal tissue (including Wavefront treatment), reshaping the surface of your eye. What this effectively does, is allows light to enter the eye and refract correctly to properly focus on objects in the distance. The higher your prescription, the higher the amount of tissue that will need to be removed. It’s not possible for this tissue to be replaced and it will not grow back.

In your consultation to determine if you are suitable (remember, this is case by case, dependent on the individual), the specialist will accurately measure the thickness of your cornea to check if it is possible to retreat. If they decide that there is not a sufficient amount of tissue to work with, you will be informed in your consultation, alongside a discussion around what your alternative options are.

Will I Definitely Need to Have Laser Eye Surgery Again?

The chances of needing a second laser eye treatment are slim, is down to the variables mentioned, including over healing or under healing.

As we previously highlighted, as you get older, you will be required to wear reading glasses or contact lenses, due to presbyopia. This may not affect your distance vision, however, that is the inevitable process of aging. This is not sufficient enough to require a second laser treatment, and is therefore not a factor that the optometrist will take into account when assessing your suitability.

Risks Of Undergoing More Than One LASIK Surgery

While LASIK is considered safe and effective by most medical professionals, it is still important for patients to be aware of the potential complications and risks involved. These may include but aren’t limited to:

. Dry eyes for several weeks or months (this can be alleviated with prescription drops)

. Temporary itchiness or discomfort of the eyes

. Nighttime glare and halos around certain light sources

. Undercorrection or overcorrection of your vision issues

    Can LASIK be performed on both eyes at the same time or it is not possible?

    • Iranian Surgery Adviser says:

      Since visual improvement is almost immediate, and the healing time is minimal, LASIK eye surgery in iran is performed on both eyes during the same procedure. Each eye is done separately, with the laser being used for less than 60 seconds per eye. If the patient prefers to have one eye done at a time, it is certainly possible, but it is rare for patients to take this route
