July 11, 2023 | LASIK

Experience Freedom with ClearSight: The Journey Towards Unaided Vision Begins Here

The world as we know it revolves around choices. From our attire to our food and everything in between, our options play an integral role in the way we live our lives. This fact extends to the realm of vision correction as well, where understanding your choices is a critical step towards making an informed decision. Among these options, LASIK eye surgery stands out as a transformative game-changer for many, offering the tantalizing prospect of life free from glasses or contact lenses. So how do you know if you're the ideal candidate for LASIK? The answer lies in a comprehensive pre-operative evaluation.

In this article, we invite you to accompany us on a deep dive into the thorough LASIK preoperative evaluation process, spotlighting what we test for, the reasons behind these tests, and how they pave the way to your personalized laser vision correction journey. At ClearSight, we believe in the freedom that comes with clear vision. So, let's get started on your journey towards waking up and seeing, being ready at a moment's notice, never losing a contact again, and eliminating the cost of glasses & contacts!

ClearSight and LASIK: Bringing the World into Focus

LASIK, the acronym for Laser-Assisted In Situ Keratomileusis, is a highly successful outpatient procedure extensively used for vision correction. This sophisticated laser vision correction procedure employs cutting-edge laser technology to reshape the cornea - the transparent front section of the eye, thereby rectifying prevalent vision issues such as near-sightedness, far-sightedness, and astigmatism.

Picture the LASIK process: An ultra-thin flap is made on the cornea's surface using a femtosecond laser. With extreme care, the flap is then delicately lifted to reveal the underlying corneal tissue. This is when an excimer laser, distinguished by its cool ultraviolet light beam, is used to minimally and gently reshape corneal tissue. Once the cornea is reshaped, the light entering the eye will accurately direct onto the retina, leading to dramatically improved vision.

Following this, the corneal flap is repositioned onto the underlying tissue without the need for stitches. The flap naturally adheres and commences healing promptly. Most patients notice a significant improvement in their vision within hours after the surgery, and visual acuity continues to improve in the subsequent days and weeks.

Imagine living without total dependence on glasses or contact lenses, with a world of freedom at your fingertips and a significant enhancement in the quality of life. To guarantee the optimal possible outcome and minimize risk, a thorough preoperative evaluation is indispensable. Here at ClearSight, we are devoted to making this journey as comfortable, informative, and beneficial for you as possible. After all, enabling you to simply wake up and see is our ultimate passion.

The LASIK Evaluation: Your Personalized Journey Towards Clear Vision with ClearSight

At ClearSight, our mission is to transform your world into a clearer one, thanks to revolutionary vision correction methods like LASIK surgery. To guarantee your suitability for this transformative refractive surgery and optimize your visual outcome, a meticulous preoperative evaluation is paramount.

This evaluation is more than a simple eye examination; it's a comprehensive assessment of your eye's specific anatomy, the quality of your vision, and your overall health. This detailed information is fundamental to assist your LASIK surgeon in tailoring your procedure to your specific needs and managing your expectations for the LASIK surgery outcome.

From Past to Present: The History and Physical Examination

The journey towards clear vision begins with an in-depth look at your past medical history, any known eye conditions, family history, and relevant systemic diseases such as diabetes. We'll also discuss your medication and drug history, as certain medications may affect healing or inflammation control.

Furthermore, the physical examination includes a detailed inspection of your eyes and their surrounding structures. Your eyelids, the anterior segments of your eyeballs, and the vital cornea are inspected meticulously. The posterior corneal surface, retina, and other inner components of your eye are also examined utilizing state-of-the-art ophthalmology diagnostics.

Comprehensive LASIK Testing: Ensuring Optimal Results

A variety of tests are performed during your preoperative evaluation to fully assess your suitability for LASIK eye surgery. This array of tests evaluates your eye's unique topography, tomography, and corneal biomechanics, along with dry eye testing, contrast sensitivity testing, and pupil testing.

Dry Eye Testing: This is essential as LASIK could potentially exacerbate pre-existing dry eye syndrome. If dry eye is diagnosed, it must be managed appropriately before LASIK. Tear film stability and quality are among the key measurements taken during this test.

Pupil Testing: Pupil size, motility, and visual axis are precisely noted in order to align your LASIK procedure.

Topography: Corneal topography is a non-invasive medical imaging technique for mapping the surface curvature of the cornea - the clear, front surface of the eye. This process involves projecting illuminated rings onto the cornea and capturing the reflection with a camera. The data captured is then computed to generate a topographical map of the eye.

Tomography: Corneal tomography is a sophisticated imaging technique that provides a three-dimensional view of the cornea. It provides detailed information about your corneal thickness (pachymetry) across its full area and the elevation and curvature of both the anterior and posterior corneal surfaces..

Wavefront Analysis: This sophisticated tool helps identify unique optical aberrations that affect your visual perception. It is a significant determinant for Wavefront-guided LASIK.

Your Journey, Your Choice: Are All LASIK Consultations the Same?

The answer is no. LASIK consultations vary widely from one practice to another. At ClearSight, we believe in a meticulous approach to patient evaluation and selection. Your initial consultation includes a full diagnostic workup using many different tests and the latest technology to evaluate your eye health.

Preparing for Your Evaluation: Why Can't You Wear Contacts Before a LASIK Evaluation?

Contact lenses modify the shape of your cornea, and it takes time for your eyes to revert to their natural shape after you cease wearing them. This period without contacts is crucial to ensure accurate measurements during your LASIK evaluation.

Determining Your Suitability: How Do I Know if I am a Candidate for LASIK Eye Surgery?

Determining your candidacy for LASIK eye surgery is a multi-factorial process, where your age, general health, eye health, the stability of your refractive error, and your lifestyle needs all play crucial roles.

However, it's not just about your suitability for surgery; it's also about providing you with a clear understanding of what to expect. We advocate informed consent, where you are empowered with all the necessary data to make an informed decision about your vision correction journey.

Potential Barriers: What Disqualifies You from Being a LASIK Candidate?

Certain conditions and situations might disqualify you from being a LASIK candidate. These include:

Unstable Refraction: If your prescription is still changing, you may need to wait until it stabilizes.

Thin Corneas: LASIK involves creating a flap in the cornea and reshaping its inner layer. If your corneas are too thin, you may be best suited for one of our other vision correction procedures.

Certain Eye Conditions: Diseases like severe dry eye, ocular herpes, keratoconus, pellucid marginal degeneration, and others may prevent you from having LASIK.

Systemic Conditions: Certain autoimmune diseases and medications can affect healing and may be contraindications for LASIK.

Unrealistic Expectations: While LASIK can significantly improve your vision, it may not always eliminate the need for glasses or contacts entirely, especially for reading in presbyopia patients.
