The cornea is a vital part of the Eye handled during eye surgery using the LASIK procedure. Also, all laser eye surgeries attempt to correct the cornea utilizing different methods and technology. Meanwhile, LASIK remains the most commonly performed surgery that efficiently corrects refractive errors. But it is not an indication that LASIK is suitable for everyone.
One of the significant factors to determine if the LASIK eye surgery is perfect for you is the condition of your cornea. Mainly, what is the thickness of your cornea before the laser eye can proceed? In other words, your corneas must be thick enough before the doctors can approve you for a complete prescription and proceed with the surgery. If not, you may have to consider other laser eye surgery methods apart from the LASIK procedure.
Then, you may wonder why the thickness of your cornea is a prerequisite for laser eye correction surgery. A simple answer will be surgery. However, we will attempt to expand on that a bit further.
What is the relationship between Corneal Thickness and LASIK Safety?
It is crucial to do a pre-surgery examination or screening before scheduling your surgery. A primary reason for this step is to evaluate the general condition of your eyes to avoid any complications during the surgery. A professional surgeon understands the importance of your LASIK screening process to determine the thickness of your cornea. This step also concludes your final approval to have a particular type of laser eye surgery and not the other.
When a patient’s cornea is too thin, it can lead to severe complications during the surgery. And instead of obtaining a better vision, it could further adversely affect the visual quality and overall health. Personal Eye is committed to ensuring that you are completely safe during eye surgery with LASIK as a company with utmost concern about your health and safety. If your cornea’s thickness could cause complications by any chance, you may not qualify for LASIK.
Corneal thickness and the LASIK Procedure
To sufficiently answer your question of the relationship between your cornea and your LASIK procedure. During LASIK, your ophthalmologist uses laser technology to create a flap from the surface of the corneal tissue to access your corneal stroma. Removing this flap allows your surgeon to access the cornea stroma and then work on it to reshape and correct your vision.
The eyes’ refractive error happens in the diverging or converging or light rays traveling through the cornea into the lens to form an image on the retina. Therefore, the correction of a refractive error is done on the cornea and requires removing the corneal tissue. However, if your cornea is not thick enough to create a flap, it may not support any thinning process on the cornea.
Corneal Thickness Requirement for LASIK
Now we have analyzed the importance of your corneal thickness to the LASIK procedure. The next question will be, what is the standard measurement of the corneal thickness valid for a LASIK candidate? Indeed, the ideal LASIK candidate must have a corneal tissue thickness that ranges between 500 and 600 microns. This range will erase any complications as a result of the procedure.
On the other hand, this optimum range is suitable because the corneal flap to be created should be about 110 microns in thickness. Moreover, the procedure can remove up to 16 microns per diopter of vision correction as an essential requirement. And according to the standard medical guideline, a professional eye surgeon ensures that a certain amount of the corneal tissue remains on the Eye’s surface.

How to Measure your Cornea
There are two essential methods to measure the cornea of your eyes in preparation for laser eye surgery. These include direct imaging or technology mapping and ultrasound technology.
