Conditions

  • Myopia
  • Optical Coherence Tomography
  • Refractive Errors

Eligibility Criteria

ALL
Age
19 Years - N/A

Interventions

  • Optical coherence tomography — DIAGNOSTIC_TEST
    Posterior segment OCT (a non-contact procedure performed over one minute) is additionally performed for patients participating in this study. Proportion of change in measurements in microns will be analyzed.

Study Details

Corrective eye surgeries, such as Lasik, are widely used to correct focusing problems such as myopia, or nearsightedness. Often these patients develop other conditions like myopic maculopathy or glaucoma which require monitoring with optical coherence tomography (OCT). Since OCT is a light-based test and changes the refractive status of the eye (in the cornea or the lens), it can potentially affect the results of the OCT measurements but has not been sufficiently studied. This pilot study aims at studying the potential change in OCT parameters in the eye after undergoing such surgery.

Arms

  • Arm: Ocular parameters
    Patients aged 19 years or more who are scheduled to undergo refractive surgery will be included in the study. OCT will be performed at baseline (before surgery), 1 day after surgery and 1 week after surgery. Each patient will be tested 3 times.
