Laser eye surgery, including LASIK surgery, is a form of refractive surgery used to correct certain vision conditions by reshaping the cornea. But can you get laser eye surgery twice?
This article explores the factors that determine whether laser eye surgery can be performed twice, including eligibility, clinical considerations, and potential alternatives.
Understanding Laser Eye Surgery
Laser eye surgery, also known as refractive surgery, uses laser technology to reshape the cornea. The goal is to improve how light is focused onto the retina, helping to correct refractive errors such as short-sightedness, long-sightedness, and astigmatism.
One form of laser eye treatment is LASIK eye surgery. During a LASIK procedure, an ophthalmic surgeon creates a thin corneal flap, lifts it, and reshapes the underlying corneal tissue. After the reshaping is complete, the flap is repositioned to heal.
Can You Get Laser Eye Surgery Twice?
Yes, in certain cases, it is possible to have laser eye surgery twice. If enough corneal tissue remains to support treatment, a second LASIK procedure may be considered, sometimes referred to as a LASIK enhancement, secondary LASIK surgery, or repeat procedure.
However, undergoing LASIK surgery twice is not compatible with everyone. The decision depends on individual eye health, corneal thickness, and the reason for further treatment.
Why Some People Consider a Second LASIK Procedure
There are several reasons why a person may consider laser eye surgery twice.
1. Residual Refractive Error After the First Surgery
Sometimes, the initial procedure may leave a small degree of refractive error. This could result in minor blurriness or a need for mild vision correction after the first surgery.
2. Natural Ageing Process and Vision Changes
Even after laser vision correction, the natural ageing process can affect eyesight. Over time, people may develop presbyopia, which affects near vision, or experience age-related vision changes that alter visual acuity.
3. Regression of Vision
Sometimes, the eye may heal in a way that causes partial regression. A secondary procedure may help correct vision again if it is clinically appropriate.
Timing Between the First and Second LASIK Surgeries
A second procedure is usually considered only after the eye has recovered from the initial surgery. Healing time varies from person to person, but ophthalmic surgeons may generally prefer waiting several months to a year before evaluating suitability for further treatment.
This waiting period allows your vision to stabilise so that enhancement surgery can be considered under appropriate clinical conditions.
What to Expect During the Second Procedure
The process of having laser eye surgery twice is similar to the first. The ophthalmic surgeon re-lifts the corneal flap created during the initial procedure or, in some cases, creates a new one if necessary. The underlying corneal tissue is reshaped using a high-precision laser to correct the remaining refractive error.
Since the corneal flap is already present from the first surgery, enhancement procedures are often shorter. However, individual outcomes vary.
Risks Involved in Having Laser Eye Surgery Twice
As with any surgical or invasive procedure, there are risks involved with a second surgery. Potential risks include:
- Irregular corneal surface due to reduced corneal thickness
- Dry eyes during the healing process
- Light sensitivity or glare
- Infection, although uncommon with modern techniques
Your ophthalmic surgeon will discuss these risks with you before any decision is made.
Healing and Aftercare Following a Second LASIK Surgery
After the second surgery, similar aftercare applies as with the first. You may need to use prescribed eye drops to aid the healing process and attend follow-up appointments to monitor your progress.
It is essential to follow the guidance of your ophthalmic surgeon and avoid rubbing your eyes or exposing them to irritants while healing.
Frequently Asked Questions
Does a second LASIK procedure hurt?
As numbing drops are used during the procedure, you should not feel severe pain. Mild discomfort or dryness may occur during the healing process.
Can you have multiple LASIK surgeries over a lifetime?
The number of possible LASIK enhancements depends on your corneal thickness and eye health. Some people may have repeat surgery, while others may not be eligible.
What if I do not qualify for a second LASIK surgery?
If you do not have enough corneal tissue or if your eye health has changed, your ophthalmic surgeon may recommend alternatives.
Conclusion
Having laser eye surgery twice is possible for some patients, provided the eyes remain healthy and there is enough corneal tissue for the treatment. An appropriately qualified health practitioner will evaluate your vision, healing, and eye structure to determine suitability.
If you are considering a second LASIK surgery or enhancement procedure, discussing your situation with an experienced ophthalmic surgeon is recommended. They will provide tailored advice based on your eye health and help you make an informed decision about improving your vision.
