Diagnosis and Tests
The path to a successful Eye Surgery begins with an in-depth diagnostic process. This is more than just a simple vision check; it is a thorough investigation of the eye’s anatomy and health. During your initial visit to Liv Hospital, a specialist will review your medical history and specific visual complaints. This evaluation ensures that you are a safe candidate for surgery and helps the surgeon choose the exact technique that will yield the best results for your unique eyes. Precision at this stage is the foundation of patient safety and satisfaction.
The first step in any eye exam is measuring your visual acuity. This involves reading letters on a chart to determine the clarity of your vision at various distances.
A detailed refraction test is performed to determine the exact degree of nearsightedness, farsightedness, or astigmatism. This data is the primary input for programming the lasers used in laser eye surgery.
For refractive procedures, the surgeon must have a perfect “map” of the eye’s surface. Corneal topography is a non-invasive imaging technique that creates a 3D map of the curvature of the cornea.
This technology identifies any irregularities or steep areas that might affect the surgery. It is essential for planning lasik eye surgery and smile eye surgery, as it allows the laser to be customized to the microscopic contours of your eye, much like a fingerprint.
Safety is paramount, and one of the most important safety checks is measuring the thickness of the cornea, a test called pachymetry. Because laser procedures remove a tiny amount of tissue to reshape the eye, there must be enough “reserve” tissue left to maintain the structural integrity of the eyeball. If a patient’s cornea is naturally too thin, a specialist might recommend a surface-based procedure rather than one that involves a flap. This diagnostic step prevents long-term complications and ensures a stable result.
The slit lamp is a high-powered microscope that allows the doctor to see the structures of the eye in three dimensions.
During this exam, the specialist looks for signs of dryness, inflammation, or early cataracts. This hands-on evaluation ensures that the “canvas” the surgeon is working on is healthy and free from active infections that could compromise the surgical outcome.
The size of your pupils in both bright and dim light is a critical factor in surgical planning. Some people have naturally large pupils, which can increase the risk of seeing halos or glare at night after vision correction. Using infrared technology, the clinician measures your pupil’s diameter accurately. If your pupils are very large, the surgeon will adjust the “treatment zone” of the laser eye surgery to ensure your night vision remains as clear and comfortable as your daytime vision.
To see the back of the eye, the specialist will use drops to dilate (widen) your pupils. This allows for a clear view of the retina, macula, and optic nerve.
It is important to ensure the back of the “camera” is healthy before fixing the front “lens.” This comprehensive checkup is standard for every patient at Liv Hospital to ensure that no hidden issues exist that could affect the long-term success of the procedure.
OCT is an advanced imaging technology that uses light waves to take cross-sectional pictures of your retina. It is similar to an ultrasound but uses light instead of sound to provide much higher resolution.
This test allows specialists to see each of the retina’s distinctive layers, helping to diagnose conditions like macular degeneration or edema. For patients considering eye color change surgery, OCT can also be used to evaluate the anterior chamber and ensure there is enough space for an implant if that method is chosen.
For patients seeking lazy eye surgery, specific tests are used to measure the degree of eye misalignment. The doctor uses prisms and “cover tests” to see how the eyes move together and independently.
This diagnostic data tells the surgeon exactly which muscles need to be tightened or loosened during the operation to achieve perfect alignment and restore binocular vision.
Once all the tests are complete, the specialist compiles the data to create your personalized surgical plan. You will be told if you are a candidate for surgery and which procedure is most likely to meet your goals.
This final consultation is the most important part of the diagnostic journey, as it ensures you are well-informed and confident as you move toward your procedure at Liv Hospital.
