Why Does a LASIK Evaluation Take 40 Minutes?

Our systematic screening process minimizes your time commitment while maximizing accuracy.


Hello from BGN Eye Clinic, Jamsil Lotte Tower Branch!

Today, I want to share a helpful tip for those considering LASIK surgery. One of the most frequently asked questions during consultations is, "How long does the LASIK eye exam take?"

Some patients worry they might have to spend the entire day at the clinic. While many assume the screening is a long and exhausting process, that is simply not the case!


Hours for an Exam? Don't Worry!

We often hear concerns from patients who read reviews about long exam times. While individual eye conditions may cause slight variations, the exam itself takes around 40 minutes!

We maintain our equipment in top condition every morning and run a highly routinized system. Even during peak seasons, our know-how ensures a much faster process than you might expect, so you can put your mind at ease.


What Does the LASIK Exam Involve?

Your eyes hold a vast amount of information. At BGN Eye Clinic, we conduct the following comprehensive tests tailored to various purposes:

  • • Vision & Refraction Test: Determines the exact degree of myopia and astigmatism to set the correction range.
  • • Corneal Thickness Test: A key indicator for surgical suitability, determining whether LASIK or LASEK is the right choice for you.
  • • Corneal Topography (Pentacam): Maps the 3D shape and curvature of the cornea to check for even the most microscopic abnormalities.
  • • Intraocular Pressure (IOP) & Fundus Exam: Ensures surgical safety by screening for glaucoma or retinal diseases.


    Why Do We Perform Multiple Tests?

    The reason our exams are completed so efficiently is due to our optimized pathways and systematic approach. However, many patients ask, "Why do you repeat similar tests?"

    The Importance of Cross-Checking

    For instance, corneal topography is performed using different devices, such as the Pentacam and Galilei. Reliable data requires consistent results across multiple machines. If the numbers vary even slightly, we must re-verify to ensure absolute accuracy. In short, these repeated tests are the ultimate safety measure to understand your eyes precisely.


    Experiencing Discomfort During the Exam?

    Some patients feel tense when asked to keep their eyes wide open without blinking. Others may squint due to the bright lights. If this happens, our optometrists are right there to help. We can apply lubricating eye drops and allow you to take a short break before gently resuming the process.


    The Surest Way to Protect Your Eyes

    The exam is not a tedious procedure, but rather the most critical first step toward safe surgery. We are here to ensure that you walk out of the exam room feeling completely at ease.
