Diagnosis and Tests
The success of Super LASIK is built entirely on the accuracy of the preoperative diagnosis. Because this procedure is customized to the microscopic level, we cannot rely on standard eye exams alone. At Liv Hospital, we use a suite of advanced digital tools to create a comprehensive profile of your visual system. This data-driven approach allows our surgeons to see exactly how light behaves as it enters your eye, identifying flaws that standard testing would miss. This phase is about more than just finding your prescription; it is about mapping your optical identity.
The most critical test for this procedure is wavefront aberrometry. During this test, a safe beam of light is sent into the eye and reflected back out.
This test is what puts the “Super” in the procedure, providing the data necessary to correct vision beyond the capabilities of standard lenses.
Since the laser will be reshaping the cornea, we must understand its surface and internal structure in extreme detail. Corneal topography creates a high-resolution map of the cornea’s curvature, similar to a geographic map of mountains and valleys.
Tomography goes a step further by measuring the front and back surfaces as well as the thickness across the entire diameter. This ensures there are no hidden weaknesses in the corneal structure, such as keratoconus, which would make surgery unsafe.
Pachymetry is a vital safety test that measures the thickness of the cornea in microns. During Super LASIK, a small amount of tissue is removed to reshape the eye.
If a patient’s cornea is naturally too thin, our specialists will discuss alternative procedures that do not involve a flap, ensuring patient safety is never compromised.
Pupillometry measures the diameter of your pupil in different lighting conditions, especially in total darkness. This is essential for preventing night vision side effects. If a patient has very large pupils, the laser treatment area must be wide enough to cover the entire dilated pupil. If the treatment area is too small, light passing through the untreated edges of the cornea at night can cause glare or halos. We use this data to customize the “optical zone” of the laser for your specific pupil dynamics.
The slit lamp is a specialized microscope that allows the surgeon to inspect the health of the eye’s physical structures under high magnification.
This physical inspection ensures that the eye is in an optimal state for healing and that no underlying inflammation is present that could interfere with the surgical result.
A healthy tear film is necessary for clear vision and proper healing after laser surgery. We perform specific tests to measure the quantity and quality of your tears. If your eyes are naturally very dry, the surgeon may recommend a pre-treatment regimen to improve the ocular surface before surgery. Ensuring that your eyes are well-lubricated helps the corneal flap heal faster and reduces the chance of experiencing persistent dryness during the recovery period.
We must confirm that your vision has not changed significantly over the last year. Surgery is only performed on stable eyes to ensure that the results last for a lifetime. We compare your current measurements with your previous records and perform both “dry” and “wet” refractions. A wet refraction involves using drops to temporarily relax the eye’s focusing muscles, revealing the true, underlying refractive error. This prevents “over-correction” caused by the eye’s natural tendency to strain during testing.
Although Super LASIK is a corneal procedure, the health of the back of the eye is equally important. A dilated retinal exam is performed to ensure the retina and optic nerve are healthy.
A clear retina ensures that the high-quality image created by the reshaped cornea can be accurately processed by the brain, maximizing the visual benefits of the surgery.
Once all tests are complete, the surgical team at Liv Hospital integrates the data into a single treatment plan. We sit down with you to review the maps of your eyes and explain what the results mean for your specific outcome. This is the time to discuss your lifestyle goals and any remaining questions. By the end of this diagnostic journey, the laser is programmed with your unique optical “fingerprint,” ensuring that your procedure is as individual as you are.
