People with dry eyes
This eye surgery may be the solution to those who are told not suitable for LASIK. One of the reasons why someone may not be suitable for LASIK is that they have dry eyes.
It is well known that patients will experience dry eyes as well as sensitive eyes after their LASIK surgery. To understand the reason why let’s get a little bit into the characteristics of the cornea.
The surface of the cornea is a very sensitive part. It has a lot of nerve endings that allow us to be aware of any injury or problem to our eye. The nerve endings that exist in the cornea are also responsible to send signals to the tear gland for the production of tear that lubricates the eyes.
The creation of a flap during the LASIK procedure severs these nerve fibers. As a result, this causes more disturbance to the signaling of tear production. Hence, the dry eyes.
ReLEx SMILE, being a flapless laser eye surgery does not involve a huge incision compared to that of LASIK. The cut is also slightly deeper and does no harm the surface of the cornea that much. Hence, theoretically lesser nerves are damaged, allowing the tear production to function normally. The time take for the nerve endings to grow back also is significantly faster than that of LASIK.
