To Study the Effects of Refractive Surgery on OCT Measurements in the Eye
To Study the Effects of Refractive Surgery on Optical Coherence Tomography (OCT) Measurements in the Eye: A Pilot Study
University of Nebraska

Conditions
Summary
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.
Eligibility
Inclusion Criteria2
- Patients undergoing refractive surgery
- For patients undergoing bilateral eye surgery, the one with higher degree of ametropia will be included.
Exclusion Criteria4
- Astigmatism more than 3 Diopters
- Visual acuity worse than 20/25
- Patients with unstable visual fixation
- Severe Dry Eye

Interventions
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.
