Laser vision correction is a credible option for vision correction amongst the more common options of glasses and contact lenses. Eye tests after laser eye surgery should not be overlooked.
For some eye surgery brings goosebumps and for others its an obvious choice. Whether you decide to go for laser eye surgery or not is your choice.
Here at Oldfields Opticians, our Optometrist is experienced in post operative care following cataract surgery, lens replacement surgery, LASIK and LASEK. Working with some of the top eye surgeons in the country he is able to bring another layer of clinical expertise to independent practice.
We can give you potential suitability options for any of the above. However, once you take the step and complete your period of aftercare, what happens next?
I am sure most, good surgery centres will have advised you to keep up with your routine eye tests in the years ahead. But what sort of eye test after LASIK is needed?
To demonstrate this, let’s take the example of a person who is shortsighted. Not just a little bit , but has a lot of shortsightedness.
The shortsighted eye has a different anatomical structure to a normal eye. The eyeball is more elongated and the retina inside is more stretched. This means that if you are shortsighted, you are at greater risk of have a retinal detachment.
The best way of checking is through a dilated examination of the retina , the light sensitive layer of the back of the eye. This allows a view into the most peripheral areas of your retina.
Other structures that should be checked after laser vision surgery are the thickness of the front of the eye and the microscopic surface profile of the cornea. This is called corneal topography and is measured using a corneal topographer.
Even if you don’t have a high glasses prescription before having lasik, there is the dryness that can follow a LASIK or LASEK procedure . This can last for variable length of time and for some 5% of people can continue beyond the one year mark from surgery.
The dryness is caused be the effect of the laser on the corneal nerves. These nerves traverse the whole of the corneal stroma, end to end and front to back
The image (taken from research gate) shows the distribution of corneal nerves which were taken from imaging the eyes of mice. The human eye being similar you can see how dense the nerve network is. In fact, the eye is the only part of your body with the highest density of nerves. Which is why is hurts so much when you get pocked in the eye.
The dryness associated with LASIK or LASEK isn’t always directly due to refractive surgery. Sometimes, you may be less conscious about the way your eyes feel before laser eye surgery but more conscious after eye surgery. This can mean you may feel things you may have not noticed before.
As an Optometrist who sees patients before and after laser eye surgery and lens exchange / cataract surgery, there are many who report no dryness when asked but show corneal dryness when examined.
Why this discrepancy? Signs and symptoms often do not correlate as the assessment and feeling of pain is relative and has psychosomatic elements.
This is why it is important to have an eye examination tailored to post-LASIK eyes.
