Diagnosis and Tests
The diagnostic phase for LASEK is a comprehensive evaluation of your eyes’ health and structure. Because this procedure involves the delicate surface of the cornea, we must have a perfect understanding of your ocular landscape before treatment begins. At Liv Hospital, we use a series of digital and physical tests to ensure that your eyes are stable and that your corneal thickness is sufficient for a safe outcome. This thorough approach is what ensures the long term success and stability of our visual results.
The most essential test in the diagnostic journey is corneal topography. This non-invasive procedure creates a detailed 3D map of the surface of your eye.
This digital map allows the surgeon to see your eye in microscopic detail, ensuring the treatment is tailored to your unique shape.
Since this procedure is often chosen specifically because of corneal thickness concerns, pachymetry is a vital test.
It uses light waves or ultrasound to measure the thickness of the cornea in microns. We must ensure that after the laser has reshaped the surface, there is still enough tissue left to keep the eye strong and stable.
The surface based nature of this surgery allows us to treat many patients who might be disqualified from other flap based procedures due to thin tissue.
The surgeon will use a slit lamp to inspect the health of your eye under high magnification. This allows for a close up look at the cornea, iris, and lens. We look for any signs of previous infection, scarring, or active inflammation that could interfere with the healing of the epithelial layer. This physical inspection ensures that the “soil” of your eye is healthy before we perform the laser treatment, ensuring a smoother and more predictable recovery period.
We measure the size of your pupils in different lighting conditions, especially in total darkness.
By accounting for how your eye reacts in the dark, we can provide a treatment that not only works in daylight but also improves your safety and comfort during night driving.
To ensure that your results last a lifetime, we must verify that your prescription has been stable for at least one year. We will review your previous records and perform multiple vision tests. This includes a “dry” refraction and a “wet” refraction using drops that relax your focusing muscles. This ensures that the numbers we program into the laser are your true refractive error, not a temporary measurement caused by eye strain or fatigue.

A healthy tear film is essential for the epithelial layer to heal quickly and smoothly after the procedure. We use specific tests to measure the quality and volume of your tears. If your eyes are naturally dry, we may recommend a pre treatment plan to improve your ocular surface before surgery. Identifying and treating dry eye before the procedure leads to much better comfort and clearer vision during the first few weeks of recovery.
Every diagnostic exam includes a test to measure the pressure inside your eye. This is a standard safety check to rule out glaucoma or other underlying issues. High eye pressure must be managed before any laser surgery can be considered. This quick and painless test ensures that your internal ocular environment is healthy and that your optic nerve is not under any unnecessary stress before we proceed with the surface reshaping.
Although this laser surgery is performed on the surface of the eye, we must ensure that the “sensor” at the back—the retina—is in good condition. We perform a dilated exam to check the retina and the optic nerve. This ensures that the high quality image created by the reshaped cornea will be accurately processed by the brain. If the retina is healthy, we can be confident that you will achieve the best possible visual result from your procedure.
Once all the tests are complete, your surgeon will sit down with you to review the data. We will explain the maps of your eyes and discuss the expected recovery timeline. This is the time to discuss your lifestyle, your hobbies, and any questions you have. At Liv Hospital, we believe that an informed patient is a safe patient. By the end of this diagnostic appointment, you will have a personalized treatment plan that is perfectly calibrated for your eyes.
Lenses can temporarily change the shape of your cornea; we need to see your eye’s natural shape for the most accurate laser results.
No, the tests are non-invasive and painless; you will mostly be looking at lights and images in various machines.
Expect to spend about two hours at the clinic, as we need time for the dilation drops to work and to perform several detailed scans.
One of the advantages of this procedure is that it is often safe for thinner corneas, but if it’s still not safe, we will discuss other options with you.
Yes, the digital map from the topography test is uploaded directly into the laser system to guide the treatment with microscopic precision.
