Diagnosis and Tests
The journey toward visual freedom begins with a thorough clinical evaluation. This is not a standard eye test for glasses; it is a specialized diagnostic session that lasts between 60 and 90 minutes. During this visit, the specialist at Liv Hospital will review your entire medical history and lifestyle needs. This evaluation ensures that your eyes are in peak health and that your prescription is stable. This data-driven approach is the foundation of surgical safety, ensuring that the procedure discussed—whether it be relex smile vs lasik—is the perfect fit for your eyes.
The first diagnostic step is measuring your precise prescription. This involves the classic “one or two” test using a phoropter.
The clinician uses drops to temporarily prevent your eye from focusing, which reveals the “true” refractive error. This prevents your eye muscles from “cheating” during the test and ensures the laser is programmed with perfect accuracy.
A critical test for any refractive candidate is corneal topography. This machine creates a highly detailed 3D map of the surface of your eye.
The safety of your procedure depends on the thickness of your cornea. Pachymetry is a quick, non-contact test used to measure this. Because the laser removes a microscopic “lenticule” from within the cornea, there must be enough tissue left to maintain the eye’s strength.
This diagnostic data is a non-negotiable safety check performed on every patient at Liv Hospital.
The slit lamp is a specialized high-powered microscope that allows the doctor to see the eye’s structures in three dimensions.
This hands-on exam ensures that the “canvas” the surgeon is working on is in perfect health. If any minor issues like dryness or inflammation are found, they are treated before the surgery proceeds.
The size of your pupils in different lighting conditions is an essential diagnostic factor. Some people have naturally large pupils, which can increase the risk of seeing halos or glare at night after surgery.
By tailoring the treatment zone to your pupil size, the specialists at Liv Hospital ensure that your night vision remains clear and comfortable.
OCT is an advanced imaging technology that uses light waves to take cross-sectional pictures of your eye.
This technology allows for a level of planning that was impossible with older diagnostic tools, adding an extra layer of safety to the surgical process.
To ensure the back of your eye is as healthy as the front, a dilated retinal exam is performed. Using special drops to widen the pupil, the specialist looks at the retina, macula, and optic nerve.
Finding and treating a retinal issue before vision correction is a vital safety step that protects your sight for the long term.
Post-operative comfort depends heavily on the health of your tears. The diagnostic team performs several tests to check tear quality.
One of the main reasons patients choose relex smile over other methods is because it is less likely to worsen dry eye. However, optimizing the eye surface beforehand ensures the fastest possible healing and the best visual clarity.
Once all the tests are complete, the specialist reviews the data to reach a final conclusion. You will be told if you are a “Go” for surgery and which specific procedure is safest for your unique anatomy.
This final consultation is a collaborative process where your questions are answered, ensuring you feel calm, confident, and prepared for your life-changing procedure at Liv Hospital.

They may cause a mild, brief stinging sensation for a few seconds, similar to the feeling of getting soap in your eye, but it passes quickly.
If your eyes are dilated, your vision will be sensitive to light and blurry for close-up tasks for about 4 to 6 hours; bringing sunglasses is recommended.
No, you must leave your soft contacts out for 5 to 7 days (longer for rigid lenses) before your tests so your cornea can return to its natural shape.
The evaluation is usually performed on patients over 18, as this is when vision typically stabilizes, though medical diagnostic tests can be done at any age.
If significant dry eye is found, we will prescribe a course of treatment to improve your tear film before rescheduling your procedure.
