Refraction is a critical part of the eye examination process at Global Eye Clinic, and we take great pride in our commitment to achieving the highest level of accuracy for our patients. Our approach to refraction involves a 12-step process that ensures precision and thoroughness in determining the most accurate prescription for eyeglasses or contact lenses. Here’s an overview of our 12-step refraction process:

- Patient History: Our experienced optometrists begin by discussing your visual symptoms, medical history, and any specific vision-related concerns you may have.
- Visual Acuity Assessment: We measure your visual acuity using standard eye charts to determine your baseline vision.
- Autorefractor Test: An autorefractor is used to provide an initial estimate of your refractive error. This objective measurement serves as a starting point for the refraction process.
- Keratometry: We measure the curvature of your cornea (the front surface of the eye) using keratometry, which is essential for determining the correct contact lens fit and assessing astigmatism.
- Cover Test: The cover test helps us evaluate how well your eyes work together (binocular vision) and detect any eye alignment issues.
- Retinoscopy: Our optometrists use retinoscopy to obtain an objective estimate of your prescription by shining a light into your eyes and observing the reflection pattern.
- Trial of lens: We use a phoropter device to insert different lenses in front of your eyes, enabling you to provide subjective feedback on the clarity and comfort of each lens.
- Subjective Refraction: You will be asked to compare various lens options and provide feedback on which lenses offer the clearest vision and the most comfortable viewing experience.
- JCC: Cylinder Axis Determination: If astigmatism is present, we carefully determine the axis (orientation) of the cylinder correction to address this irregularity.
- Duochrometest: A duochrome test, also known as the red-green duochrome test or the red-green balance test, is a visual assessment tool used during an eye examination to refine the prescription for eyeglasses or contact lenses,
- Bifocal/Progressive Assessment: For patients requiring multifocal lenses, we assess your near and distance vision needs to prescribe the appropriate bifocal or progressive lens design.
- Final Prescription: Based on the results of the 12-step refraction process and your individual preferences, our optometrists determine your final eyeglass or contact lens prescription.
- Prescription Verification: We verify the accuracy of the prescription and ensure that it provides you with the best possible vision correction.
At Global Eye Clinic, we prioritize accuracy, patient comfort, and personalized care in our refraction process. Our optometrists stay up-to-date with the latest advancements in optometry to provide you with the highest standard of vision care. Your satisfaction and optimal visual outcomes are our primary goals.
